Ok
So today long road test high speed.
No leaks!
Parts used:
MINI COOPER R56 TRANSMISSION INPUT SHAFT SEAL OEM PART 24127551992
Job was also done without special tools:
1. I used drill and screw method to remove old seal, make sure not to drill in too deep, use a depth stop at around 3mm then use self tappers to extract the seal 50/50 as side evenly until it pops out.
2. I used a bearing install tool, the flat side as the middle hole fits perfectly over the shaft and you can tap almost flush to the bell housing, the shaft gear stops you going all the way flush.
3. I used an over sized bearing extractor to hit the seal home until it was flush with the bell housing.
Hope this helps.

 

Holy *****, the case cracked from the wrong flywheel being installed?! And you're reusing the same case even though its cracked?

You a better man than me...mine leaked like crazy after installing OEM seal.

Good call. I wouldn't have touched the seal... Knowing what I know now.

Did you install the seal dry or lubed?

 

HaHa no way Lex, the trans with the cracked bell housing is scrapped, I replaced it with a new used trans, but I took a gamble and changed out the input shaft seal with a brand new OEM one!
I can tell you it was worth the gamble the seal was easy to replace and didn't require any special tools, I did smear the outside of seal with my finger covered with trans fluid. The new seal has some kind of white grease already applied to the inside contact so I left that as is.
I wiggled the TC a few times and couldn't line it up the pump so I had to pull the TC out a few times, I did notice the white grease was liberally covering the TC shaft I think it took me about three goes until it locked into place, and then I proceeded to to fit it back to the motor.
I defiantly don't want to be pulling the motor out again, the job was a success and I DO Reccomend anyone that takes the transmission out to check the bell housing for cracks, and replace the seal it's not as bad as it sounds, and there is no way you want to be doing this job twice!!

New used transmission with new OEM seal fitted and new TC.

Wrong ring gear

For anyone contemplating doing this seal job I fully recommend it as there is nothing worse than having to monitor fluid and constantly cleaning under the car. For those of you that still have fluid leaking I doubt it is the bushing as even new bushings still have a lot of play, just make sure the two dowel pins are there and you carefully tighten the TC to the ring gear.
Hope this helps someone as I couldn’t find any positive threads on changing the seal.

 

Sweet bro! Hope she stays sealed up!
