How easy is it to overtorque tranny pan?
Hey everyone. How easy is it to overtorque the tranny pan on a w124 300e? I changed the filter/fluid and drove to Houston from Austin and left my car in parking for a week. When I took it out again I noticed the tranny gasket was leaking. I found out the gasket had a tear in it causing it to split. I ordered a new one and put it on but my battery is dead so I havent been able to fill the tranny back up yet. I am just concerned that I warped the pan. I had torqued it by hand using a medium sized socket ratchet untill I felt enough resistance that moderate effort wasn't turning the bolt. To be honest I am pretty sure I warped the pan but I just wanted to make sure I am not being paranoid.
Oh, and the pan was not leaking during the drive, so I am not concerned about any possible damage to the transmission. |
Very Easy to overtorque, take the pan off and look at the holes for any distortions, take a ball pean hammer and gently tap down and raises in the pan and re install with new gasket, I think the torque for this is around 15ft lbs but not sure, no need for a torque wrench, just snug them evenly and tighten in an offsetting pattern like you would do when tightening head bolts

Thanks for the quick reply! I have never straightened any metal or seen it done so could you please ellaborate a bit? Just set the pan down on a flat surface and use this hammer to hammer the tabs perfectly flat? I noticed one of them was raised up when i put the pan back on (in the middle around the holes for the bolt). And do you know type of store would carry a ball pean hammer? Im afraid im not familiar with this tool. Thanks!!!

If bolt holes have pulled out the lip around the bolt hole, I would lay the pan flush on the table say and then ues any hammer and a thin stripe of metal and place it over the hole and litely tap the area out until flat. |
Torque on these bolts is only 8nM - newton meters. To get lbs. you take approx 3/4 of 8 and come up with 6 lbs - seems kinda light. I torque 'um up close to 10 lbs - no problems yet.
My 2 cents. |
