Loctite Sleeve Retainer 640

Anybody ever use this product? I've had several people recommend using this to secure my right main bearing (bushing) in its housing. Bearing tolerances are good in relation to the crankshaft, but the outer diameter of the bearing is a slip fit into the housing. Machinist told me yesterday that I was throwing money away by giving up on this old bearing. All of the good old JD mechanics in this area are dead, and the local machine shops are scared of tackling the job of machining the new bearing. Tractor is a 630 John Deere. Bearing is the right side main bearing - 4 inch journal diameter.

I have used this product with good results. Obviously, it works best when the area to be filled is not large. If it were me, I would get a good measurement of the outside of the bearing and the inside of the housing. If the area to be filled is very small I would use this product confidently. Mike
 


PJH,
Here is who I highly recommend to take care of your problem. Manitwoc Motor Machine in Wisconsin. Ask for Scott. 1 800 666 9129 They manufacture the correct alloy main brg. and can correctly machine your housing & bearing to fit.

That's not what you want. Lcotite makes something else for bearings and races.
I don't remember the name so I will have to check.
 
I have used that product or something similar with good results.
Even if you installed a NEW bearing I'd still coat it with some kinda Loctite to make sure it stayed put.
IIRC yours was not too loose in the housing and the dowel pin had it held from spinning.
If cleaned really good and loctited it should stay put.
Don't know why they think it is hard to machine a new one ? Anyone with a lathe big enough to clear the housing can chuck it up on the outer flange and bore it out to size.

I was looking for another small tube of the silver Loctite for the really loose stuff and was not having any luck at local auto stores.
 
It is quailty stuff. I use it on alot of bearings that I install whether it is on a tractor a peice of manufatcuring equipment (Lasers, Plasma, Puch Presses) that I service. Remember one thing, both surfaces must be clean. You can buy the loctite primer or use Acetone. The loctite primer is about 95% acetone.
 
Thanks Earl - I found info about those folks in Wisconsin, but I had already ordered the bearing from John Deere by the time I learned about them. Now experienced mechanics are telling me that I should re-use the old one - it has .006 inches oil clearance on the journal, but the outer diameter is a tight but slip fit into the housing, hence the need for the Loctite. Original problem with the tractor was engine oil getting into the reduction gear cover. Seals were hard and brittle, and then I found the bearing loose in the housing and thought I needed a new one (blame my limited mechanical experience).
 
Thanks Mike - I'm gonna try the Loctite. My most promising machinist has the equipment to do it, and said he would if I pressed him, but thought I was wasting money on the new bearing and labor. He also recommended using the Loctite sleeve retainer on the new bearing, if I chose to install it. The parts guy at our local dealer said I could return the new bearing for future purchase credit, minus a 20%? restocking fee, which is fair when you think about how much aggravation it is to deal with fools like me, ha.
 
Thanks Mike - the clearance is very small between the outside of the old bearing and the inside of the housing, but I don't remember the decimal that the guy measured yesterday. I remember that there is .002 inches of interference between the outer surface of the new one and the inside of the housing. He would have liked a little tighter press fit, and that is why he recommended using Loctite on the new one, if I chose to install it.
 
Make sure the pin that keeps the bearing from spinning is a good tight fit. Was the Deere bearing a aluminum alloy or bronze ? The bronze material, I have seen too many failures.

Earl, both the old and the new bearings are aluminum.

The locating pin fits real tight.
