That Fookin YPVS Clutch Arm Bearing

[headcoats]

Just spent an eternity removing the clutch arm needle bearing ...
Did one about 15 years ago and vowed never to do another ,but this one was fecked from vapour blasting which was done before I bought them.

Tried the rawl bolt method and a heatgun but wasn't having it and was worried I would crack the cases over tightening to get it to grip.
Only got it out when the inner cage disintegrated and it left a lip on top of the outer sleeve and I got a sharp edged screwdriver and a couple taps it popped out !
Question now as these bearings are pretty delicate,what is best way to put a new one in ??
If I remember I think I heated the cases and tapped it in using a socket but slept since 😴

I didn’t enjoy fitting the one i did , i put the bearing in the freezer, the casing was just heated in the boiler cupboard as it had just been painted tapped in with a socket it wasn’t easy , I think i would make a dolly next time that fits inside the bearing to keep it straight

They are so delicate aren't they.
Does anyone have the part number for bearing please?
Did hear the aftermarket ones are wrong size ??

Long bolt and large washers every time to pull it in

The sharp shocks is what distorts them

And stop being lazy, part number is on Fowlers website 🤡

I made a drift on the lathe for putting them in, it has a long part that is a snug fit inside the needles and then qa "top hat" so that it seats nicely on top of the bearing cage, bit of grease and one nice tap with a nylon hammer and its in - made the drift out of ally

I’ve only ever replaced one, more for precaution with a new engine than anything else

I don’t remember it being that difficult to remove or replace

I used a Toledo bearing tool that JonW put me on to many years ago, it removed and installed all the bearings in the cases

I have a method to get them out easily thankfully. I just weld a small bit of bar into the bearing. The heat heats up the cases too and makes drifting it out a doddle.

I removed a really stubborn one yesterday.

Firstly, I took the inner cage out by bending it in with a small sharp screwdriver, the cage and rusty needles just fall out then.

Spent 15 minutes with the blind bearing puller but it wouldn't budge.

Carbide bit went in my Dremel type multi-tool then I carefully cut through the cage and it fell out.

Whole thing took 25 minutes tops.
