borg warner T10 leaking
« on: January 24, 2013, 07:12:17 PM »
Fluid is coming out of the input shaft...pulling hair out...how hard is it to change the gasket?

I'm not 100% certain on this but I'm pretty sure all you have to do is take off the 4 bolts for the front bearing retainer. There should be a seal in there along with the outer gasket. Shouldn't have to take the whole trans apart.

How hard was it to swap the gaskets?

3 months of regular driving its fine now, reverse lever o ring needs replacing, extension housing needs to come off, will do that when i put a new clutch in it, I've had my fair share of oil leaks from this ST10, both selector shaft seals & side cover gasket, two rear extension housing seals, All G@@d now, got my bits from this place,

If theres a breather anywhere on the top of the box, make sure its not plugged with dirt etc.....Don't know about ST-10s, but I've seen gearboxes and transfer cases leaking before due to a plugged vent.

Are you sure it's the input shaft leaking? Muncies and ST-10s counter-shafts are supported at the front of the (aluminum) case by a predrilled hole. When this hole becomes "baggy", it'll tend to drip out the front of the tranny. not saying this is your problem, but something to check while your tranny is out, and you're sealing your frt brg retainer.
