Model T Ford Forum: Forum 2013: Oil pan distortion
Top of pagePrevious messageNext messageBottom of page Link to this message  By Craig Haddock on Sunday, September 29, 2013 - 07:10 pm:

Hello,
I removed the pan from a 23 touring that's been in the family since new. I've been reading about the oil pan distortion and sure enough, the pan is tweaked. The bolt holes from side to side don't line up and the 4th main doesn't fit properly unless I fit a taper punch through the pan to block holes on both sides. This lines up the pan to the block and pulls the rear of the pan over almost far enough for the bolt holes to line up on the rear bearing cap. With all the stresses that are placed on the pan from engine weight, front end stabilizer torque, possible frame distortion, it seems like simply straightening the pan might not be enough to keep it all in line after everything is bolted into place. Am I over thinking this? Should I try putting it together and just pull the tail end of the pan into position or should I have the pan straightened? BTW, the pan came off to repair the clutch driven hub which had all of the rivets coming loose. Is there anyone in or near Michigan that straightens them? Didn't mean for this to get so wordy. I would much appreciate any help or advice.

If it were mine I would straighten the pan. Relive as much stress as possible on that crank shaft.

That could be the reason for the rivets coming loose. There would also be a lot of stress on them from this distortion of the crankcase. The stress will also be on the crankshaft which will cause the main engine bearings premature wear and could cause the crankshaft to break. Find someone with a straightening jig to straighten it out. After you straighten it so that there is no strain to keep it in line, your engine and transmission will thank you.

Craig: You might get in touch with Phil or Mark Eyre. They're near you and I would think they'd know where you could get a pan straightened.

If you can't slide the rear main cap on without interference, you need to find someone with a KRW pan fixture, and get it straightened.

Not having much luck finding anyone with a pan jig in the Michigan area, seems that most of the rebuilders that use them are on the west coast. Also seems odd that with as much emphasis as there seems to be about ensuring the pan is true that there aren't more people offering the service.

I don't have access to a straightener either, so I used an 27 block with the hogs head bolted on, worked out well, did 2 pans on it.

Craig, Joe Bell was kind enough to allow me to visit his shop in Tiffin to use his pan jig on mine a few months ago. He also helped me by adding some reinforcement (brazing) to the pan arm rivets. It's back together and in the frame. Fitted up exactly as everyone describes it should, with no binding. Take him up on his generous offer, you'll be happy you did (I am - Thanks again, Joe!)

Thanks all and thank you Joe for the offer. I'll get hold of you to set up a visit.
