My transmission replacment thread

MyBlackBeast · Oct 30, 2010

I am in the process of replacing my T5 ,clutch and rear main seal. I have had a rear main seal leak for a long time. I even changed it twice before. This time upon further inspecton i noticed there is a groove in the crank shaft and the seal was torn up as you can see in the pictures.

MyBlackBeast · Oct 31, 2010

Is it normal to have those groovs on the crank? I was thinking of using some very fine sand paper?

Mustang5L5 · Oct 31, 2010

I think after a while the seal does wear a groove. I didn't look to see if mine had a groove when I changed out my seal. I think I remember reading that repair seals position the seal in a different spot so it wouldn't ride on the groove?

I do know when I replaced my seal, it leaked for about 500-800 miles after that. Then it stopped. I have changed the oil, so the level is fine...just the leaking stopped.

5l5 do you think it would be a bad idea to use some fine sand paper on it?

Mustang5L5 · Oct 31, 2010

Not comfortable saying yes. I wouldn't. I'd search around and see what others have done. I know I have read about this before, but not sure how people handled it

Ps...I have heard good things about the felpro Teflon rms....however it was after I installed a ford racing new rms.

Btw..my rms install tool. Worked nicely

MyBlackBeast · Oct 31, 2010

5L5 thank you for all the info. I like your install tool. I will have to pick one of those up from home depot.

There's a part just for this situation called a "redi-sleeve" that fits tightly over the existing crank surface and makes a nice new non-grooved surface for the seal to work against. I'm betting you can get one at your local NAPA.

Best answer so far... This is what I would do.

The PVC plug used for an installer is another great tip... Not all of us know how to fix everything, but some of us know how to fix some things with excellence!

Ok i did some searching and i found speedi sleeve. I think this is the right one? Can anyone confirm that?Amazon.com: CR SKF Seals Speedi sleeve 99362: Automotive

MyBlackBeast · Nov 1, 2010

I just got off the phone with microsleeve.com. I orderd the bearing sleeve and install tool. For the sleeve the tool its only $30. I will let you guys know when it comes in and how the install goes. I cant wait to install the T5 i rebuilt.

I just got off the phone with summit. I ordered a 255 walbro fuel pump and upper control arm bushings. I figured while my car is up in the air ill take off this stuff to. Also im gonna put the 94-95 Fuel rails on.

They beat me to the speedi sleeve idea

MyBlackBeast · Nov 2, 2010

Is this the right t5 tail seal. The one that is on the t5 i took out of my car looks diffrent.

That first seal is the one that came installed in my rebuilt T5, while it was brand new it leaked from day 1. The seal 5L5 posted is the one you want for sure.

MyBlackBeast · Nov 4, 2010

Yesterday my micro sleeve came and so did my 255 Walbro fuel pump

MyBlackBeast · Nov 4, 2010

So im looking at this repair sleeve installation tool and i think i need some other tool to conect to it to make it work. Has anyone done this before? What am i missing?

kpack5982 · Nov 4, 2010

I'm curious on this question as well. I have replaced a rms twice and had oil leaking issues almost right afterwards. So basically the sleeve goes on over the crank and then you need a new rms correct? Is it the same size then also? An illustration would really help, even if it is just made in paint or something
