This should be simple, but I'm actually starting to wrack my brain. I changed my clutch, pressure plate, and throwout bearing. No problems, the job went well. Now, though, I've got a minor but steady transmission leak. For example, parked in the same spot for about 4 days, there is about 5 ml on the floor (a spot mostly soaked into the concrete, about 3" across). This seems to be coming from the bottom most bolt on the rear of the trans housing. I've torqued these all down evenly (even though I hadn't touched them during the clutch job), no change. The only weird thing that happened with the clutch job was that at one point the trans slipped and rolled on its side, so I *suppose* it could have broken the gasket seal or maybe even given me a hairline crack, but I can't see any evidence of either and it seems real unlikely--its not like the trans took a wicked hit or anything. Possible I overfilled the trans a little, but then I'd expect fluid from the breather hoses. Anyone else had tiny mystery leaks from their manual trans?
JMM, Years ago I was helping a buddy of mine at the Heavy Equipment shop, a similar situation occurred on an older, large, rubber tired front end loader. I wasn't crazy how he exactly had it set up to install, but him having a little more experience than me, I was willing to go with it, not seeing anything really detrimental to the operation. The trans. also slipped, as it started to get hung up, as they usually do, being higher off the ground, and a lot heavier, clunked to the ground, kinda gently, but same thing. Everything looked okay, I then made a couple suggestions, and we put our heads together and got her in! My other friend Tim, the old timer that I like to refer to saw the whole thing and kinda snickered! We still laugh about to this day, because we love to use the quote from the movie Jeremiah Johnson, when Will Geer was teaching Robert Redford, the so called ropes of living in the wilderness, and he didn't dig his bedding hole deep enough, for the hot rocks to keep him warm at night, and Will Geer said "SAW IT RIGHT OFF"! sorry, it still makes me laugh!!! But with the trans., yeah that one leaked too, we pulled it out and resealed the gasket with high temp silicone gasket sealer, that's been 12 to 14 yrs. and I know it's still being used almost everyday, with about 16,000 hours on it! I stop in the H. E. shop every morning at 5:30 to have coffee with my old friends, just to say hello, cause I know nothing lasts forever! Not sure if that's your problem or not. Good Luck! Limestone
Before you get in a rush, think a bit. You said you possibly overfilled it, check that first and lower it if needed. Clean the case good with brake clean to ensure it is completely clean & dry, then monitor closely for any seeps or streaks of oil. With a clean & dry case you should be able to trace it without too much trouble. Fred
Hi - could you tell me what torque spec you used for the transmission pan bolts? Thanks! We have a leak after the dealer changed out the clutch for us and I can't find the torque specs in the Danko service manual.
Most manuals don’t give torques for standard fasteners. The head bolts, and bolts holding the main and connecting rod caps, are nonstandard. And, manuals give you torque specs for them. Bolts have markings which tell you what quality of steel they are made from, and how hard they are. On metric bolts used on the minitrucks it is a number. On ASE Imperial bolts used on american cars it is a pattern of slashes, to tell the “grade” of the bolt. Count the slashes and add two, and you have the grade. There are charts/tables online, (Google: metric bolt torque, and look at images). The left column is normally the bolt diameter and pitch, for example 6-1.00, means it is 6mm in diameter, and the threads advance 1.00-mm per turn. The top row of the chart has the numbers stamped in the bolt heads. Find your bolt size, and where that row intercepts the column coming down from the bolt strength, is your torque.
Juju, I don't understand! If you had a dealer do your Clutch work. Aren't they responsible for the Leak! Warranty? Enlighten me, please! Limestone
@Juju1187, I've attached a PDF of torque settings, but a CAVEAT: it's for the S80/S81. I have not yet found one of these for the S83, so please use at your own risk!
I would Imagine that these specs tolerances will be very close. Close enough to work to, instead of guessing! It's definitely better than nothing! Limestone
I don’t understand. Changing a clutch shouldn’t involve fluids. If something leaked it would be out of tail shaft. And if a tranny gasket is leaking it would just be a coincidence.
When I replaced the clutch, I changed the trans fluid. Developed a tiny leak, finally surmised that it was just a slight overfill on my part.
