Engine/Transmission (1994 - 1998) Leaking Rear Oil Seal ???

[TFPace]

Hello All!



I have removed the transmission & transfer case as one unit.



It worked nice, jack placement is important.



I have a SMALL leak on the rear seal and everyone says replace it!



I called Cummins Atlantic and the service guy said the speedy sleeve is not used any more.



My question is:



How do you remove the seal? I have seen a puller made by K-D.



What type of a press is need to install this seal?



Does anyone have the part number for the seal? If the is a groove cut the shaft apparently Cummins has an over-sized seal instead of the Speedy sleeve.



Thanks,



Tom

got it out

I used a slide hammer and it popped right out.



Now off to the seal store!



Thx!

National makes a ready sleeve. . don't have the number handy. The same national seal number would be used afterward



The Cummins arrangement is a thick brass/bronze sleeve that gets pressed on with a high dollar tool. Then they give you an oversize seal in the package (much larger seal id, as the crank is now larger by say . 150-. 200).



The front seal from Cummins is approaching a 100, and the last one for the rear was close to a 125 if memory serves.



However, we don't want any leaks, even overpriced/good seals are reasonable compared to transmission/transfer case r&r.

I replaced my rear seal even though it was not leaking when I had the trany out. I replaced it with a National brand I bought through Car Quest. I paid $58. 48 and it works great. I see no point in paying the high Cummins price on this particular part as it's made with the same material and National seals are tops in my opinion. Part number is JV1622 if anyone cares. As far as removal goes I just pull the rear seal housing off the engine and use a screw driver and hammer to knock the seal out, it's real easy.

Another way to remove this type of seal is to drill a small hole in the steel part of the seal, screw in a self tapping screw, then use a nail pulling type bar to pull the seal out.

I just put one in a 98 12 valver yesterday. Like illflem said, drill an hole and screw in a screw. Then I pulled it out with a pair of vice grips.



I bought the seal from Cummins NW and it was $50. 33. It came with a plastic guide to be sure the lip doesn't fold over and a metal ring to drive it in with to assure the proper depth. If you need the part number I can get it but tell the parts guy what youre working on and he'll get it right. I've had really good luck with those guys.
