This is a video describing how to properly set the Cam Gear backlash on a 3406E or C15 engine. This can be one of the most confusing parts on a C15 to set up properly, after watching this video though it will be easy to set.

Hey there, like your vids, they're very informational. I have a 3406E in a freightliner classic, truck run strong but... somewhere in the middle of the day my yellow check engine ligh comes on and almost immediately the red shut down engine light comes on they blink anywhere from 3-16 times before it turns off my engine, almost immediately they will turn off and the engine will operate normally again. All gauges are normal and engine doesn't studder or no noise or vibration from engine. would you have an idea what to look for or at?

Hey Josh, I know most people do not have a CAT back lash Bone but that's how I've always done it along with the timing pin in the 3/8 hole you're pointing out. So you really only have to use the hole and the tool is not used?

@nickforgey509 3 жыл бұрын

I know this is an old comment but if the head has been shaved or if the block has ever been decked the alignment hole will not work because the head, and cam gear, are physically closer to the idler gear. The back lash will be too tight and could spin the front cam bearing due to the gears trying to move away from each other under torque. I just snug two of the nuts on the stub shaft and tap it with a soft dead blow hammer until I get the back lash right, then torque everything with blue loctite.

I have rebuilt c-15's with a reman head the head was cut I set the timing gear with the pin backlash was tight I use a great tool for backlash cat tool #462-5095 it's a segment gear check it out

@johngoldsmith6629 5 жыл бұрын

Yes I am the guy who invented the gear. Showed it to a Cat factory man and in a few years guess what tool CAT released? I made the first one out of a normal gear that had a tooth failure (still use it). Cam gear CCW, increases lash, while CW decreases lash. I set my engine cam and crank on TDC 1. Install my cut gear and measure my lash. If I have to adjust lash sometimes I use the feeler gauge as a stop point. Usually a .006 and rotate cam gear until it starts to get tight. Snug my adjuster get feeler gauge out and recheck the lash. The .006 keeps from hitting the min spec. After I feel lash/timing is close enough and torqued adjuster. I than reinstall running gear and recheck lash. For some reason my cut gear can change lash by .002. All this mess started in the MBN days and CEL was coming on for timing out of phase. We had to replace reman cylinder heads just installed for this. Cat than increased lash a few times to solve the problem. I try and get as close to the timing mark as I can with lash in the window. I really don't like less than .010, but have to go with what you got.

hey Bro have a question for you. i have a BXS cat that i recently overhauled pulled front cover down and re-bushing all the gears i have been fighting code 22-11 for weeks now and i can not seem to get it to go away. I have been working on Cat motors for over 15 years.. and i have never had this much trouble with one . Truck did not have this problem before i repaired the motor. if you have ever had a problem like this please let me know what you found wrong. i have followed Cat SIS troubleshooting sensors are new and i have check OHM reading they are to cat specs and sensor are genuine cat. Today I tired another Camshaft gear in it and had same issue. I pulled transmission out of truck to make sure flywheel was on Dial pin on back of crankshaft. LOL I REALIZED after doing all that the flywheel can be checked by making sure both holes pin on driver and passenger side of motor. My next thing is doing a timing probe to reset the timing. if that does not work i am pulling the front cover again to see if the cluster gear is ok

@killercoolcole2698 2 жыл бұрын

@adeptape Question and hope to get an answer soon in my 3406e cat testing and adjusting manual it say my backlash should be between .003-.010 and what you showed is .011 different. Wonder if that was updated by cat or is just different in newer c15 manuals

@johngoldsmith6629 Жыл бұрын

With the dual sensors added and at that time Cat was offering reman heads that was shaved. Sometimes you could not get the lash in the window. So current spec is 0.014 +/- 0.010. Or min of 0.004, max 0.024. Try and stay off the min. Single sensor engines are more forgiving. Dual, you might get a CEL as you could be out of phase.

Roy Rodriguez Hi, I enjoyed your videos. I have a 1994 Peterbilt 379 with a 3406 B. Truck was running good until the turbo went out. Unfortunately the mechanic that was working on it miss diagnose the problem. The truck had lost power and was smoking real bad,,real bad. He replace all 6 fuel injectors then had me rebuild the fuel injector pump then he realized it was the turbo. After he put everything together the truck sounded like it was on steroids and still was smoking a little bit. I took it to another mechanic to check the timing and supposedly was out 2 teeth. But every time it went up a hill loaded it was lacking power. starting from the bottom off the hill it will only go to 35 or 40 max loaded 72,000 total weight. If it was driving at 65 and hit a hill it will go down to 40's. Engine sounds weak too. Any advice to what to work on. I am from Chicago west suburbs and is hard to find a mechanic that knows how to work on this older engines. Thanks Roy

I gotta crazy problem with my 3406b that no one can figure out. full inframe, head reconditioned and injector pump done but will only run, albeit not quite right (low boost hard starting poor power) with fuel timing retarded 2 or 3 degrees. I'm thinking cam timing is out. Care to way in?

@johngoldsmith6629 5 жыл бұрын

Did this start after rebuild? Who rebuilt engine? Cat dealer or local shop? Advance timing will cause low boost. Full serial number, major part numbers of replaced parts. Example, head, cylinder packs, nozzles, injection pumps. Also any part number that has to do with performance.

At 4.47 mins it , you are talking about putting the 3/8 bolt in the alignment hole . I did not see any 3/8 bolt in the video. is the bolt a tight fit in the hole. but the bolt has thread on the end of it , going into that what looks like a smooth bore alignment hole. You just lost me on that bit . I need to see the bolt in the hole , and how much play is left in that backing plate that u tighten with all those nuts ?

No it was the reason I lost the last engine. Constant blue smoke (not oil). New injectors and no change. turned out to be creating hotspots to the point it drilled down into the pistons until it blew out a chunk of number 3. then inframed and still had the blue smoke and barely started. Then injector pump (7W7800) fully rebuilt and still smoked and wouldn't start. Tried advancing fuel timing but got worse so tried retarding timing and got much better.
