whos bearings are better than stock and yet made for the mini? anyone?
i'm tearing down soon and would like good bearings if needed .

 

Are you asking about wheel bearings?? If so the wheel bearings are integral to the drive flange/hub on our MCSs. Sooooooo I don't know if there is an aftermarket supplier that has smoother more precise wheel bearings that could be mated up to our existing drive flange/hub. Good luck with the tear down!

 

no engine bearings . mains and rod .

 

Ahhhhhh of course. On that note what about the cam bearings/caps??? Anybody?

 

i haven't looked at that issue yet ,though the valve train is also a candidate . are there bearing inserts in these heads? or does the cam just ride on the quality aluminum ?

You will find few if any aftermarket big end bearings for the MINI engine because the stock ones are so darn good and high quality BMW evidently got some decent third party engineering company to make them.

No reports yet of 500+WHP turbo cars spinning bearings and whatnot, so I would stick with OEM...oh wait, I have

Cheers,

The word is the bottom end is rock solid. Guys are pushing practically twice the OEM horse power out of this engine and no reports so far of bottom end failures.
Of course it is smart to ask first, i.e. doing your homework.

 

There are no cam bearings inserts in the head. Like so many OHC engines these days, the cam rides directly in precision bores in the aluminum head. This system works well, since the cam itself does not have anywhere near the pressure placed on it as does a typical OHV design. Spring pressures are a lot lighter since there is no need to overcome the weight/inertia of pushrods, lifters and heavy rocker arms. The only thing that can affect longevity of cam bearings in most cases is continuously running the head very hot, be it from overheating, water pump cavitation, etc. Temps will run so hot that the oil (especially if substandard) cannot do it's job.

 

I picked up a good 5whp replaciong my muffler bearings with swiss bearings from my skateboard. J/K :p

 

kinda thought so as that's how it is with most *** bikes. i've had an oil starvation problem in the past and am just lining up all the ducks so the car's not down too long . so mini manias are probly stock ?

 

Thanks for the note Greatbear! I guess if the precision bores in the head and the caps are worn then a new cylinder head core plus cam caps will be in order. Hopefully our heads will last 250,000 miles or so with regular servicing!


Yes cavitation from over spinning a water pump will cause cooling issues. Anybody out here with a 15-19% underdrive blower/water pump pulley that's had cooling issues during an odd summer track day(stock rad/thermostat/coolant/oil)?
