Or cross reference for the bearing that resides in the clutch cover on a 750GT. Part Number 75155.2054.
It needs to be replaced.
Also, does the case need to be heated to get the bearing out.
Thanks in advance, Dean

Bearing number is: 6204Z (20 x 47 x 14mm)
Bearings are usually sold with ZZ (2 metal shields).
Remove one shield and install the bearing with the remaining shield facing OUT.
The bearing is held by a large snap-ring. Heat MAY work.
A blind bearing tool WILL work on this and the wheel bearings for the next 20-30 years.

We stock a high quality blind bearing removal tool, yes more expensive than the eBay knockoff tool but you do get what you pay for

Thanks Den and Steve,
Den you have come to the rescue again.
While you are rescuing maybe you or someone else can help explain the bearing situation that I have?
I removed this bearing from the clutch cover because it was rough to turn and thought I should replace it.
Once I got it out, it spun freely and smoothly

. So I figured maybe it had crud in it from the case shavings and by heating and removal it freed up the crud. So I cleaned the bearing up, made sure it spun freely, quietly and smoothly and put it in the freezer overnight and the next day heated the case back up to reinstall the bearing.
Now the odd part. Reinstalled the bearing and now it is very difficult to turn. Will not move much less spin.
Obvously I'm going to have to take it out again and this time put in a new bearing. Why does it spin freely out of the case then lock up once in?
Thanks for your help,
Dean

That's a puzzler. If you have a vise try this. Put the bearing in the vise
and tighten it a little and see if that makes the bearing lock up. This is all
assuming that the bearing, fresh out of the freezer, isn't freezing up the grease
or anything like that.

Well the bearing was hard to turn because the inner spacer was pressed against the inner race when the bearing was seated. So, I removed the bearing (again) and enlarged the hole in the spacer to clear the inner race on the bearing. Problem solved

Thanks for you input Den and Steve
