372xp...bearing spins in case...toss?

[Mattyo]

I have two clutch side halves that are loosey goosey....to a 6202 nachi bearings....the bearing plops right in with out heat.

Toss the case half?

Jb weld the bearing in?

 

[jacob j.]

I wouldn't go JB Weld, but Loctite makes a sleeve retainer- Loctite 660, that might work, depending on how loose the bearing is in the pocket. Loctite 640 may be another option.

 

[TimRD]

Loctite is definitely the way to go. Just be careful of the type you use as Loctite specifies their products based on the maximum gap you are trying to fill. May want to consider high temp too.

 

[jmssaws]

Locktite the bering in and go around it with a punch and swell the case.

Seen lots fixed that way.
Probably won't last forever but neither will we.

 

[Mattyo]

loctite 660 ordered .... $12 including ship on the bay


seems like jb weld would just just as good...no? rough up the bearing a bit and the case and go for it?

If there's room for jb weld between the bearing and case throw it away.

gotcha....tx

I have a case that I tossed cause of this. Gluing the bearing in doesn't give me the warm and fuzzies. Thought about staking it, but ended up with a new bottom end for my 2071.

 

[Lee H]

If it were me. i would fix it right since your already in there
with a good used case or a new one. Have you priced a new
one? With the amount of 372's out there a good used one should
be easy to come by.

 

[Mattyo]

For the record. ...I've got a different case entirely that I am using.

Decked 2 cases today on the Bridgeport mill. ....a good day

 

[Mattyo]

But I am curious to see if it can work

 

[smokey7]

I've used loctite retaining green stuff for up to .030 in 350* stuff with no issues. Only problem is getting it apart if you needed to. I recommend the primer for it also as it will give it the extra edge. Have faith it's going to work and work well. I used that stuff all the time.

 

[sunfish]

Loktite will work. JB is too thick.

 

[Mattyo]

I can't imagine that this is 5 thou off.

 

[Al Smith]

Loctite has a product called "press fit" that works fairly well .Raise the metal with a prick,awl or whatever you have in the bearing pocket and drive it home .Let it sit overnight and assemble .They used that stuff at work for wallered out bearing pockets on heavy duty multi tooled machine spindles and it seemed to work .Now we're talking 25 HP electric drive motors on those spindles .

 

[rustypete]

a centre punch and dab it right round the case that the bearing is slack it works for me every time did it all the time on slack housings

 

[srcarr52]

You can always overbore the case and make an aluminum sleeve.

 

[Aciera]

Use the Loctite primer.
Let it set.
If there is like a couple thou use 638. If not. 660.

I have a ported 044/046. Used 638. No problem.
Use the primer.

 

[RIDE-RED 350r]

I tried the Loctite bearing sleeve on a 575 case with a bearing that would fall out...I did make some raised bumps around the bearing bore with a prick punch too.. I'm not an experienced machinist but the fix didn't last...

That was my first and only attempt at such a repair and by no means am I suggesting it is not a good fix or that you shouldn't try it.
