Can someone tell me where all of those bolts go on the Model T Pan and Transmission bottom. What size and type bolts and where do they go to be correct? Thank you for help......
Contact Dave Huson and you could take a look at his stuff. He lives just south of you.
Bolts are 3/8" x 24 threads, installed from the bottom and the nuts are on top of the engine pan rail. If you are using a starter hogs head you will use 3 bolts that are shorter into same.
Hope that helps. Correct bolts will not have any grade marking on the heads.
Installing the pan, assume you have straighten it. Install two bolts on each side of the crankshaft, put fourth main in place and start a couple of bolts. Install the balance of nuts and bolts, starting from the front of the engine working to the back and check that the fourth main will slip in and out without any pressure.
If you use the std timer you may want to place the bolt right under the timer upside down so the risk for untimely grounding of one coil is eliminated. Be sure to test fit the fourth main/ ball cap before tightening the pan bolts so you know the pan is in the right position.
Best is to have the pan checked on a pan jig (if possible) and mount the pan while the engine hangs in a stand nose down, so the heavy trans doesn't bend down while checking the forth main fit.
If you have the corner reinforcements at the block/hogshead joint you may need a little longer screws there. But it isn't essential. Ford stopped using cotter pins on the pan bolts in december 1924, so lock washers is enough to keep the nuts in place.
