Oil Pan Removal - 25 inch motor in B1B

[jmooner3]

Working on a 1949 B1B built in California, It has a stuck cyl - some great insight from Greg g, 1949P17BC, Townwagon....etc. Figured I'd post to the forum and see if anyone has wiggled a 25" pan out of a 49 pilot house.

Original motor was a 23inch block now it has a 25inch 1950 Desoto. I'm looking at the pan and it looks like it is shoehorned in. The previous owner moved the front motor mounts and the rad to fit it in...That said I suspect the original 23" pan would have slid right out from the front cross memeber and cleared the axel and steering linkage...I haven't tried it yet but this pan goes up over the front cross member where the original rad sat I suspect and no room at the clutch/trans. Even with the steering linkage out of the way, It looks like there is not enough play to get it out? Anyone worked a 25" pan out of a B1B? Strategy to do this in the truck or am I back to pulling the motor? Pix attached.

Thanks Jay

Loosen the front Motor Mount from the frame. Jack up the engine with using a piece of wood to support the load, the block the mounts up with some thing between the feet and the frame once it jacked up. Should be able to get couple two three inches of wiggle room. Drop the back first the the front "should" come clear.

Thanks Greg, I don't have an engine hoist - What's the best way to get the motor up? Can I jack on the underside? I suspect you can't jack right on the oil pan? The truck is in a barn with truss roof, I can build a lift to get it from the top but if there is a way to jack from the bottom that would be easier. And how far up can I go before I risk screwing up linkage in the rear or rear mounts letting go? I think if I get the steering linkage out of the way and get the front motor mounts up on a couple 2/4s as you suggest I can pull that pan.

Jack it with a block of wood to spread the load. As you are only going to lift the engie ad not the weight of the truck, unless the pan is weakned from rust it should be fine. just go slowly, and have something ready to put between the motor mount and the frame as yoou lift.
