Assembly begins on our classic Mini Cooper S 1275cc engine

Looks like Davin has everything he needs to get this 1965 Austin Mini Cooper S 1275cc engine back together... or so he thinks! Assembly begins with camshaft bearings and the camshaft. Then it's onto checking the main bearings and rod bearings for oil clearance, which is when Davin realizes we have the wrong rod bearings. Oops! That doesn't stop him from getting the crankshaft installed as well as assembling the valves and springs into the cylinder head.

A quote (roughly) from a book about tuning the Mini "Tuning for Speed, Tuning for Economy"; "It is not uncommon for a well tuned Mini to completely strip it's intermediate gears". Enjoying your videos, bringing back teen-aged memories of stripping down and rebuilding my Mini engines. Didn't have an engine hoist, made one out of two ladders, a 2x4, some rope and block and tackle, worked well but I was much, much younger then. My Cooper S had to have new rocker bushing installed and drilled, they were cast, my Dad took them to work and got them done over a couple of weeks, in the mean time, I had two complete rocker arm assembles, pressed steel type, prone to breaking in a 1275cc eng., in the boot just in case one to the rockers in the engine broke, which happened several times. I could remove and replace a rocker arm assembly and be on my way in ten minutes. I did it all, rebuilt the engine, transmission and replaced the clutch, all in my Mum's laundry room! Even did some minor body work. You wouldn't believe the corning ability of a Mini with hydrolastic suspension lacking fluid, had a leak, fixed it, let the other side down to drive the 25 miles to a dealer to get both sides refilled. I have so many stories... I wanted a Mini in my 30's to 40's, finally found one aged 50, after getting in and out, I realized that I was no longer as flexible as I used to be, drive a RAV4 now, love it but not even close to my Mini Cooper S. Good luck with your rebuild, stay safe.

In 1966, the Cooper S took the first 9 places at Bathurst, beating out the V8 Studebaker amongst others. In 1967, Ford Australia released the "Mustang Bred" 289 Falcon XR GT, which bettered the Cooper's best lap time by a full 7 seconds.

Between 1960 and 1972, the Mini won 32 rallies around the world, including three wins at Monte Carlo. Should have been 4 but in 1966 the first 3 positions held by Minis were ruled out as the French found an 'issue' with the headlights so the 4th placed Citroen could win. For the first Monte win the cars had the 1071cc engines. The 1275cc came afterwards.

@@devandrasimanjuntak1646 Depends how you define 'power dependent'. Having a big, heavy cart sprung beast that needs to slow down as it wallows around corners needs a big V8 to make up for the speed lost in that poor handling at corners. Minis are lighter, have brilliant suspension and so can go full chat round bends which means big power isn't needed. They just use the power they have all the time.

I "shrink" each cam bearing by leaving them in a cooler of dry ice overnight prior to installation. Liquid nitrogen is more efficient, but dry ice is logistically easier in every aspect (and exponentially less expensive). No need to drive any frozen cam bearings--each slips into place and each expands to fit within a few seconds.

My dad was a machinist who did all his own auto repairs. As such, I was raised in the garage and, as a kid, did all my own bike and car repairs. But I left that behind years ago and now use my “office hands” to make appointments so that others can do most of my mechanical work. This series is so meaningful in terms of my ability to remain in touch with my “working with my hands” past where eye protection and “blue gloves” were unknown. I still dabble with bikes and a race car, but I was always a amateur “component mechanic” … good at installing carburetors and brakes, not so good at pulling cranks. These videos take me back to my youth in dad’s garage. Thanks for this content. It is meaningful beyond words. Dave in Seattle

Always sadly reassuring that even the experts sometimes go, "Oops!" :)) One thing about depending upon tear-down photos... They should be good if the engine has never been rebuilt - essentially if everything is just as it was from the factory. But if some yayhoo already rebuilt it without the same care Davin is using, it would be put together the same wrong way a second time. No?

That is some nice machining work and bad luck with the rod bearings! But on that distributor jackshaft you engaged in the cam before the crankshaft went in that will have to come out! Basically you time the camshaft first and then slide the jackshaft in noting it rotates as it goes in using 5/16" UNF bolt to thread into the jackshaft to stop it becoming part of the gearbox! Ultimately you want the rotor arm pointing to "1 o'clock" @ TDC Compression No 1 piston

@TheLastSock 2 жыл бұрын

I always remembered that the Distributor could be rotated to match TDC, so it doesn't matter where the shaft is fitted, once you set the camshaft and Engine to TDC, you can rotate the distributor separately to TDC then adjust for your timing. Mind you its been over 30 years since i rebuilt my 1000cc Mini engine so my memory might be on the fuzzy side.

When I was in the business I rebuilt dozens of these "MOWOG" engines and I was always in a state of wonder as to how these little devils powered so many different vehicles. They were certainly not designed for a long life but they were designed to be easily rebuilt. The big failing in the Mini though was the fact that the transmission and the engine both used the same oil since the trans was actually the engines oil pan. All those metal particles created from the trans syncro rings and bushings were free to get into the engine.

Over on HREIRL 's channel, were a skilled Mini engine builder is doing a race engine build up currently, he advises only using valve seals on the intakes, as the exhaust valves/guides do not benefit from the seals (no suction to pull oil down the guides) and actually benefit from small amount of oil reaching the guide bore/valve stem wear surfaces. BTW, what happened to the block gouges in a previous video? Did they machine out?

hey not to be rude but with the snap gauges.. you loosen the top part of the gauge, pinch the anvils to where the are smaller then the bore you are looking to check. lightly tighten the top hat. then put in the bore and loosen the top hat again it will snap to the bore size. from there tilt the gauge letting the anvils get a little bigger in the bore . lightly tighten the top hat and with one motion tip the stem in the opposite direction you had it leaning. this will push the anvils into the snap gauge until it reaches the smallest size of the bore. that is how you get the most accurate measurement from those.

Those have some downsides, doing one engine per season box lasts for a long time, when you run the shop it just adds to cost. They are not the most accurate, when you already have bore/snap gages and micrometer's set you'll get better results (and you will have to have those to measure other things that you cannot with plastigage). Cleaning remains is sometimes cumbersome. As far as I remember there are different thicknesses of plastigage strips depending on clearance measured, so doing many engines you have to have few boxes.

Back in the 1980's and early 1990's, plastigage was what we were taught to use in school and we never questioned it. I have been out of the business since 1995, and kind of lost touch, but now everyone on KZfaq does the measurements and math instead of plastigage, so I have the same question.

I find that kind of odd as well.

So when you go to recondition one of them unless you measure every journal you could be caught Needless to say once it was running it didn’t take very long for the bottom end to be knocking its balls off and the whole thing had to come out again……..!!!!!!
