My stepdad has an old Ford 9000 and they did the same on that truck and That Was 1980 Something. And she's still a good driver to this day.

There are more than one "Cat Yellows". I used to work as a cat engine mech here in Finland, and we always had to check which cat yellow we order as some engines were of lighter yellow than others. So, we had two different cat yellow spray cans to choose.

I’m an agricultural engineer for a claas dealer, some claas combines use cat engines and they are painted in a claas grey, no hint of yellow underneath that paint either

Sterling: orders 34 06s and C15s for their trucks Guitar riff

2 more fun facts: - Cats are often stolen for their metals - Cats hate you, but expect love

I’ve worked on private yachts my whole career and every cat engine I have turn wrenches on they come from the factory white but underneath if you chip the paint it’s cat yellow.

White truck engines were very common in the late 70's and early 80's.

Your videos are always full of great information. I’m getting ready to start a equipment technician program that’s sponsored by Quinn CAT at a local community college. I watch your videos to get some training on the company and their products. Keep up the great work!

There is nothing stopping a customer from buying a Cat engine & painting it whatever color he wants.

I did enjoy that, I’m such a diesel nerd :D I was fascinated by the Mitsubishi D3 and there were generators with komatsu gauges.

I have worked on 7 ships with 24 Cat engines between them. Main engines, generators, standby generators, emergency generators, every one of them was yellow.

There was actually two “cat” yellows starting in 1931 it was Hi-Way Yellow until 1979 when it was changed once more to the Official Cat Yellow we all know now

God, I love CAT so much

Interesting trivia about Cat diesel engines . Always amazed with your video content Josh. Learn something new every time . THANKS Amigo.....

In regards to the deal with the connectors, the term you're looking for is _"commonality."_ Many believe the amount commonality a product has is an example of how well it was designed and engineered. Personally I find that a very hard statement to argue

Great Video Josh as always I found it interesting that Cat only used one electrical connection. I have found other proprietary Cat features that really refine them Maybe you could do a video on the origins?Ive noticed Fastners,Hydraulic couplers Turbos and the cast iron It makes for a better product because everything is built to their standards

The naming of model SN prefixes to people is absolutely correct. An example is the LBM which is named after an Australian engineer working in Mossville at the time whose initials were LBM. From memory this is a Euro 3 C-12. Lou was liaison for rest of world (North America being prime) engine spec/design at the time. An awesome engineer who could go into any of the meetings by the various specialties (cooling, fuel, emissions etc) and be able to be very knowledgeable in each of them. “A Jack of all trades is a master of none, but often times better than a master of one” very much describes Lou's abilities. The Deutsch connectors where selected over every other connector available at the time due to their easy of serviceability and reliability. They were selected over the proprietary Cat connectors. The 3406B PEEC and 3176 (released at the same time as the DD S60) engines used them but using the HD style connector (same pins and sockets). However HD connectors proved to be both expensive and large so with the C-10/12 and 3406E they changed over to the DT connectors which are used to this day. The brown engines were an exclusive FL spec as part of the way Cat got into the FL80 build. FL wanted be able to say the engine was exclusive to them.... The engines actually being identical apart from the paint. The Ford LTS and Sterling needed the slant engine and in Australia it was even harder to get the engine in due to the RHS config putting the steering shaft right thru the turbo..... The 3406C (I think, may have been the E) was eventually engineered in though on the journey the breather was in the way which ended up with the classic line from the Cat account manager saying to just remove it....... For some reason the engineers didn't agree with this suggestion. FYI we had the 3208 installed in the Ford Cargo as the only engine for many years and had to store 2 years supply (from memory) when Cat stopped production but the truck was still being made.

The injectors on some of Cat Engines (HEUI's and C's) had not the regular Deutsch Connector style, because are made by Navistar. Under an emergency situation, I used injectors from a DT466E on a Cat engine. No issues (no trim code modified). And regarding the Cat yellow paint... that paint is also designed to change the shade of yellow towards the darker brown, even black, depending of how hot the component has being working. So that way, the Tech only need a quick look to find overheated component. CAT even have charts with the color shade and it's temperature range related

A friend has a CAT engine in his trike, mated to a 5 speed BMW gear box and a Ford back axle. The engine was out of a gen set , a three cylinder, CAT technical helped him along the way as a gen set runs a one speed a trike car ect needs a rev range. Top speed 65mph but excellent fuel economy.

Note to self: add engine when searching for "brown caterpillar" Unless you want to look at a picture of a bunch of caterpillars

Almost all the older military CAT engines were originally yellow, then were overcoated with the CARC (Tan or Green/camo, depending on the year) until they started shipping them raw to let the military contractors do the CARC coating directly. Most new CAT engines in military vehicles are that lovely mustard yellow.

The Cummins was also tilted in the Ford/sterling trucks.

By the way I love ur videos ur mic is great u can explain things great too. Great job man

The 3406A model Cats were painted white. Also the Ford LN9000 trucks had tilted engines when using the 3406 engines but they also done the same when using the 14 litre Cummins Big cam engine. I think it was all just a matter of fitting the larger engines under a short hood and the doghouse in the cab. Also Cat over the years has used many different shades of Cat yellow for their yellow paint.

Earlier Ford's with 3406b like the 1980s LTL9000 had tilted engines also.

The Sterling tilted engine is left over from FORD days . Ford was great for doing this. My guess is it gives the driver more foot space !!

CAT yellow has changed over the years. At least 3 times that I have come across so far.

Next time someone sends me cat facts, I’m gonna send them Cat facts.

Worked for cat doing R&D on the medium and heavy duty engines. Had a full feature file for a 3406E that had a marine map accidentally loaded in it. It pulled a fully loaded trailer up route 6 hill like I was in a corvette. About 1200hp.

I have seen cats that were painted white in Kenworth trucks from the 70.

Thank you! I am glad that I found your channel and subscribed. I just wish that I had found it sooner.

I don’t know anything about CAT engines but KZfaq knew i would be interested

My dad worked for a dealership in the 80's.. I saw more than a couple of Cats that were white (for marine engines) and a few that were red. The red ones were fire pumps. I saw a few custom engines that were kind of cool. A matching pair of 475hp 3208ta's that were white with chrome trim (rocker covers, air cleaner box, ect) for someone's pleasurecraft. If I recall correctly, the Cats that were in the Army Corps of Engineers dredges in the area were gloss gray with chromed trim also. Those were one offs, but the majority of the engines (even marine application), marine gears, and gen sets I saw were indeed Cat yellow.

Marine cats are usually white and so were the 3406a truck engines.

I sure love CATS, but decided to repower my truck with a Detroit.

Thanks for sharing this info, Subscribed to you're channel

Oliver 2255s (later White) used the Cat 3150 and 3208...they were painted Meadow Green. The White 2255 used red, and the replacement 2-180 had their Cats painted black. I grew up literally one mile from Caterpillar's Mossville engine facility and my father was a metallurgical engineer there...I was in the plants a fair number of times and saw all sorts of colors used on engines, including dark blue, possibly for Ford's Louisville Line. The white engines were probably most common from what I remember, after Cat yellow, of course. I recall seeing workers wiping the white engines down after dyno testing as they got fairly grungy.

I have worked on many 3126 cats. They were all yellow. And marine applications, such as yacht boats/ fishing boats, they are often white.

Thats what i thought ! I have have 3 olympian gensets that have the 4cyl perkapillars in them ! Good engines for being 20 years old !

There was a period when Cats in Petes were painted white. Not sure if Peterbilt was painting them or if Caterpillar was painting them at Peterbilt's request.

Cats were also painted white in Paccar products aka Peterbilts and Kenworths in the Late 70's into the 80s. Until the introduction of the C series Cat if you ordered the 3406 engine in a Pete or KW it came in painted White.

Cat were also painted white in trucks, and marine power engines.

Cat 3406 was white in peterbilts in at least 1986 as a buddy had one. He said white was the origianal color for that year. I had a 1987 3406B in a Pete and it was the typical cat yellow.

Very cool CAT trivia. Thanks!

Benjamin Holt started Caterpillar in Stockton, Ca. If for some strange reason you find yourself in Stockton, the Hagin Museum in Victory park has most of the entire lower floor dedicated to Benjamin Holt and early Caterpillar equipment.

I worked at a freight co where we had yellow and brown(ish) 3126s and the the tilted C15. I believe the brownish ones were 3 valvers.

The Ford LTL series was well known for the " Crooked Cat"

Neat video! Related to #1, Cat built olive drab-colored engines for military vehicles. My M35A3 has a olive drab 3116 in it.

Was hoping you would cover gas compression engines. I’m new to the gas compression business. 3606 is our big engines. 2000 hp ish.

KZfaq recommending me this after watching too many cat videos....

Fact....that expensive yellow paint will bankrupt you

I can remember some 1693 truck engines being off white back in the late 70s & early 80s

Early Cat tractors from the 20s were all gray and some special individual ones from expositions were white. Check out the tractor museum in Woodland Calif.

White marine, red fire engine, green military, grey and blue. Shipped pink for a lady trucker.

I was always curious about the 255 fault count thing.

most interesting and unexpected - thnx!

Great stuff...love it

This channel is fucking awesome, love your work man

The sterling thing isn't entirely correct. Sterling was originally Ford heavy duty trucks, sold to Daimler (which owned freightliner) then rebranded as sterling. The sideways engine thing was happening well before the ford HD truck division was sold to Daimler and Cats weren't the only engine they did it with. I know they did it with the cummins N14 because I've worked on them, so it's possible that they did it with others too.

excellent history lesson! thanks!

Thank you for sharing your knowledge

You make following this process of yours, to bring precision and durability, service excellence into the life of a rebuilt machine / engine a superb and inspirational joie - thank you kindly. Will follow closely, as time goes on, ex ZA. May 2021 be good and kind to you, us all, and shed some of the overload of ‘bads’ of 2020 with determined grace. All of the very best...

Our fire department used nothing but the CAT 3406 series diesel engines until CAT quit producing them. We still have one in service with over 170,000 miles on it and still nothing has gone wrong. Normal maintenance and monthly oil changes.

CAT's come in more colors than yeallow. Their marine engines often come in white. The reason they seem to "lean back" in the engine bay to help with prop shaft alignment (trans to rears).

FYI, The C9s in 2011 and up Claas harvester combines are grey.

I had a 1976 International Fleetstar 2010 A ( think that was the model). Anyway it had a 290 cummins which was installed on a slant also. Also had the doghouse in the cab as part of the engine stuck inside.

Years ago we had a 1960's Diamond -T (990 Series) with a 220 Cummins that was tilted to fit under the hood and cab. Interesting truck it was.

Cat changed their color from a standard safety yellow (at the time) to their own proprietary color today sometime in the 80's, but they certainly didn't tell the various mfg facilities to throw all the old paint out. And yes, the Chief Engineer gets to pick the SN prefix for a model change, within reason.

Caterpillar marine engines are painted white from the factory. Deutsch and ampseal connectors are both made by Te Connectivity.

There is actually Old cat yellow and new cat yellow.

Cat does build a marine engine that is painted orange. I worked at LEC in Lafayette Indiana.

Hey men I love your videos. I have a c12 cat motor in my freightliner. I watched every single video you have made about cats. Helped me understand my engine, thanks a lot. Quick question, I live in ohio and I just changed my oil to 5w40 T6 Rotella. Engine sounds a bit louder is that supposed to be like that or is it just in my head?!

Ive seen Cat engines in blue, grey, black, green, orange, red, you name it. Then again, I work on the industrial/marine side, so whoever makes the machine paints it to match the color of whatever the engine is put into.

This is the cat version of an anime nerd video- I love it

My dear Friend, please do videos on engine Testing & Adjusting training videos series please. Huge fan of your work !!!!!

White and orange are also often found on cat engines, white for pleasure craft Marine and orange is typically emergency power for hospitals

I recall seeing numerous white painted 3408's 1693's 3406 a and b's

I hauled asphalt with a 1995 International Paystar 5000. It had a 3406C and also sat at a angle. There were many people who asked me how come my oil pan was on crooked.

The 86 "cat engines in peterbilt trucks" bro sure shows all the engines in white.

The 1150 or 3208 Cat put in Ford trucks in the early ,mid 70s were painted Ford Blue, and in fact said Ford Diesel by Caterpillar ..

Another great informative video from the Cat Master. Yeah I know it wasn't about pulling pistons or replacing timing gears and other manly stuff...but it was chock full of cerebral stuff to feed your mind....and besides for a few minutes I got to quit watching Hallmark Christmas videos with my wife.

C11, C13, C15 in 2006 ACERT for paccar had 30 distinct yaws and pitches. The oil dipstick selection is very important. Good news is that assembly guys and girls will verify selection with engineering when question arises.

My Dad and myself ran heavy equipment building roads, our favorite was Cat, the power and durability of these earthmoving machines was remarkable . My nephew has a freightliner with a Claterpillar, if it ain't a Cat , then it's a Rat.

When you are working on a new product introduction at Cat, someone gets to pick the prefix and they all have some meaning behind them. Someone behind the curtain approves or denies, basically like customized license plates. I have heard of teams raffling off the right to designate the prefix, going towards charity and such.

It's always a surprise opening the hood on Sterling when one comes in lmao. So far I've worked Sterlings with the MBE 900 and 4000, Cummins isc, 3126, and a C7.

3406 engines in paccar truck products were white in color in the early to mid 80’s.

My grandpa worked for Cat in their Hydraulics from the 60’s through the 2000’s. Learned coding and general computer skills to stay ahead of the curve, all for me to make the connection that the Cat’s Byte and Black Ops 3 Zombies have the same “255” problem

I know that International licensed the HEUI injection design from CAT, but those injectors you showed look EXACTLY like Powerstroke injectors, down to the goofy 90 degree electrical connector.

In the water pump house where I work, the Cat engine that powers one of the pumps is red.

Ford L9000 brought on the crooked cat with the 3406B prefix escapes me it was 20 years ago when I saw it.

The cats that I have seen in the ROAD BOSS are also tilted.

I can confirm that the component serial numbers are often made up from the inetials of the product group lead engineer or engineers and the number of kids in there family or team members. This is an option rather then a rule. Also white is a colour option available in the marine product range, you can also chose yellow, white or black filters. Early Ford truck engines pre 3208 (I think 3196)engines were blue. Cheers mate🍻 As always very good information, keep up the good work👍

Color, quite a miss on that. Original CAT engines were actually Battleship Grey with red lettering, and all the way up into the 1990's many engines were white. The white ones were common mainly in marine and industrial uses, though they would occasionally be found in trucks as well. The CAT yellow was originally called Highway Yellow, before it became Caterpillar Yellow, and a great deal of effort was invested into finding the color that would stand out the most on a construction site.

Hopefully some day you'll have an opportunity to work on the CAT APE engine

I retired from Cat after 41 years and I can attest to the fact that that the alphanumeric serial number prefix were often the initials of the lead engineer, the lead project manager or the program manager responsible for the new product introduction.

New cat yellow and old cat yellow.. I worked as a engineer on a dredge it had 4 D370's and 2 3306's and 1 3304 they were old cat yellow when I repainted them it was in new cat yellow. Cheers Rory PS the were and are an awesome engine all of them they were new in the mid 1970's.

Cat marine engines are usually Matterhorn white.

Nice to have decent background music, too!

The C-7 had the nastiest smelling exhaust of any engine.

Drove a feed truck with a 3208 in it with a straight pipe up the side. That baby would cackle nice!
