front main seal.

if you put oil on the seal, then it wil leak oil almost immediately. how did you install the wear sleeve? it is rather hard to do, and cummins has a special tool that installs the seal flush with the crank gear, so that it runs true with the crank. not saying that you installed the sleeve incorrectly, just that i have seen some botched installs, and the cust. couldn't figure out why the seal wouldn't seal... anyway looking at the pictures, that groove looks very odd to me. i see where the seal lip is riding, almost directly in the middle of the sleeve, that looks normal to me, but im not sure how that groove twoards the front got there?? now you got the sleeve kit form cummins, it should of came with the sleeve, larger front seal, plastic install sleeve, and metal seal depth "tool" the seal kit part # is 3802820. now i do know that you cannot use the the regular size seal with the wear sleeve, you can force it over the sleeve, but it will destroy the seal, and major oil leaky. can you tell me the number that is on the seal that you took out, and on the one that you installed just to double check and make sure eveything is right? thanks!

yeah i can probably get that for you tomorrow its back in the shop. i know that they sent me the seal and sleeve all in one box, not to say they put the wrong seal in the box at the factory but it was all in one kit.

i have seen the tool for the rear seal but not the front. i used a rubber mallet to install the sleeve and just tapped it back and forth on the sides to get it flush with the end of the crank.

if you can come up with some pics to show proper use with that install tool for the seal to double check if i used it right or not?

i think its that far forward because i didnt seat the seal back far enough. i know that it didnt leak for about 6 months after the install then it just started slowly leaking more and more up to this point where i just put a cheap carquest on to by time while i just do test drives and stuff around locally since i have company vehicles to drive around
 
I got my seal from cummins, put some red lock tite around the edge, and then used the little metal ring it came with and drove it in. I THINK I did it from the front, can't remember though. Either way, it doesn't leak.
 
yea ill get some pics tomorrow at work of the whole kit, and how it install it properly. there is actually another tool that is used to install the front oil seal, it does a much better job than the cheap piece of metal they give you int he kit. if anyone is interested the part # for that tool is 3824498, and the wear sleeve install tool number is 3824500. ill take a pic of the tools tomorrow. it looks real similiar to the rear main installer, basically all it is is 2 studs with nuts that screw into the crank threads, and a metal cap that has a small internal shoulder that is just big enough to push on the sleeve, and fit over the crank diameter. you put it together, and use 2 nuts to slowy work the sleeve onto the crank. ive never tried to install a sleeve with a plastic hammer, i guess it would work, but the nice thing about the tool is it will bottom out the sleeve against the crank gear, so you know it is on the crank nice and true.

folks there's a way to avoid using the speedy sleeve kit. which of course is pricey and not needed if your can move seal inwards to use a different spot away from groove.

almost all 12v will wear a groove on front crank spindle. surface that crank seal rides has enough room to allow seal to be installed further inwards. the new seal doesn't have to be placed back in original position. which would align back up with grooved crank and leak.

sorry I don't have a picture to illustrate. what you are trying to do is set new seal to align with fresh crank surface area.

note new seal is lubed with silicon grease. plastic insertion sleeve MUST be used or you will destroy new seal.
 
I know that my new seal was only like 30 bucks from carquest and came with the speedy sleeve. I couldn't just slide mine in the whole surface was roughed up and had to use the sleeve. This is all great advice and should help anyone in the future with these seals
 
that's great info to know carquest has em for $30.
paid $80 from cummins for the last speedy sleeve kit

so you are saying that the carquest seal thst is supposed to be for the regular crankshaft diameter also comes with a wear sleeve?? that does not make any sense. cummins uses 2 different size seals for a reason, and includes the larger seal with the kit. im not sure how carquest is using one size seal for 2 different overall diameters? am i reading that right or am i wrong?

Wes
 
the only one that i found at carquest was the one with a sleeve in the kit. not sure if it was the large one or factory one with a sleeve. the picture it showed on their weblink only showed the depth tool and the black dust seal and the clear guide to slide the seal onto the sleeve. there is no other details about it. i tried crossing the cummins number on there and came up with nothing so they dont even have a cross reference on there.
 
cummins uses a different size oil seal, but I've successfully used sleeves with stock seals on transmission output shafts, etc.

it really depends upon how thick sleeve is... all seal have a certain amount of tolerance.

speedy sleeve calls for a thickness of .094in or 2.39mm ... that size sleeve requires a different size oil seal. Wear sleeves - SKF.com / Products / Interactive Engineering Catalogue/Industrial shaft seals

don't have one in front of me, but sure seems the last sleeve kit from Cummins used an oil seal a with noticeably larger ID than stock oil seal.

the carquest oilseal/sleeve is a mated set just like the OEM Cummins set. so I'd use it without worries.

skf makes a version that wears better called: SKF SPEEDI-SLEEVE Gold your local bearing house can order it for you. Wear sleeves - SKF.com / Products / Interactive Engineering Catalogue/Industrial shaft seals

My old sleeve measure appeox 0.062" didn't measure the new one but looks about the same
 
the old seal part# 3922598 and if you can see by the pics that it was not installed straight because you can notice it was wearing on one part more than the rest like it was crooked.

yup... there needs to be a BIG warning... hardest part is installing oil seal dead straight into timing case.

after spending much time without success, trying manually starting seal with a seal sized drift.

finally figured out the best way is to press seal into place with a hand crank press.

yeah my dad has one of those in his shop 4 states away lol wish i had one around to use would of been a whole lot easier to do
 
bringin this one back...
i'm going thru the same thing right now, trying to locate an oil leak. first thing, how do i get the seal out of the timing cover. i tried smacking it from the front and back. didn't really get crazy with it felt kinda sketchy, didn't want to bend my timing cover..... and can someone give me a link to the best place to buy my new seal.
thanks
 
put it on a wooden block to absorb some of the impact to keep from bending the edges. i normally beat it out from the back of the cover with a punch or screw driver. depending on how you want to go about it you can get one from cummins or go to a local parts store and get one. the one i got from carquest was like 30 bucks and it came with the install tool and speedy sleeve to put on the crank.

when you go to install the seal on the cover just get it flush with the outside of the housing and then when you get the cover back on use the tool to set the depth and to set it straight with the crank to keep from causing the issue i had when i started this thread. also they have a clear plastic guide that comes with it when you got to slip the cover on will assist it not tearing up the seal.

once you have the seal over the clear plastic piece then you can tighten up the bolts that way you are centered on the the crank.

not sure if that is all the proper procedures to do that but thats how i would do it to keep from replacing the seal every 6 months.
 
48383 is the carquest part number of the seal i used and it was like 30 bucks as i had said previously in the early part of this thread some others chimed in with the cummins part numbers.
 
Thanks chevycummins, but I can't find anything on the carquest site. Do I need an account or something looks like there was a login to get to parts
 
i have a weblink with the local carquest and thats how i found it. you should be able to go to the store and give them that number to get it.
