TR2/3/3A What size speedi-sleeve needed for pinion seal on a TR3?

Hey guys,
I've continuing my frame up restoration on my "58 TR3 and am replacing seals on the differential. There are signs that the pinion seal was leaking and I was hoping to use a speedi-sleeve to solve my leaky problem once and for all. The flange shaft doesn't seem to have a wear ridge or any pitting but since I have the whole differential out and sitting there... now is a good time to get it done. I live in Canada so shipping from Moss motors gouges me every time - I have a local NAPA parts supplier that has them - I just need to know what size to get for the pinion shaft. Anyone have the SKF part number?
Thanks a bunch!

If the sealing surface looks undamaged but there is evidence of oil leakage it is most likely coming from the splines. I would just clean up the flange sealing surface with some emery tape and use some aviation gasket cement on the splines and the large flat washer and it should be good to go.

Pinion repair sleeve is 99149 if you do go that route.
 
I have limited experience with speedy sleeves. Some years back I tried one for the front seal and everything went fine until I tried getting the shaft back into the seal; it would not fit because the sleeve made the flange too large.

Perhaps if I would have gotten a larger seal with a bigger center hole things may have worked. after it did not work I instead cleaned the flange with very light emery cloth and put some JB into the small pits and used the emery cloth to smooth the shaft.

Anyways Napa is usually pretty good about helping, so I would suggest taking in the seal and flange and see if they can set you up.

Thanks again guys! I looked at the shaft again last night and I could feel the smallest wear groove where the old seal was. So I’m going to try and get the Speedi-sleeve 99149. I will also seal the flange surface too. No leaks is the goal!

Our buddy Randall suggested that the seal and grove will probably not be in the same place the second time. kinda like stepping into a river in the same place twice. Also check that the PO did not put a scare in the case if the old seal was replaced. Those factory seal were leather and high quality and can really put up a fight coming out, so be very careful of the case. Perhaps put some of your favorite sealer around the outside of the seal when you knock it in.

Took the seals out last night... and you are right. They were leather. Didn't have much trouble getting them out though. The proper tool was handy. A seal puller with a slide hammer. Worked like a charm. When examining the axles for groove wear - one side had a fairly nasty groove. Also, the new seals I got from Moss are thinner and I bet you are right in that they would wear in a different spot. However I still feel as though getting the speedi-sleeves in will be a nice insurance measure. Picking those up on the way home from work tonight :bananawave:
