212 Splasher Engine

I got a gasket set for my 1939 Hudson 212 splasher 6 engine. Could any one tell me if I have to remove the timing gear to replace the front engine mount gasket ? Do these leak very often here and is it really necessary to change this gasket?

Do you have to take the timing gear off to get the gasket on or are there bolts or connectors behind the timing gear? I have the timing cover off but not the gear. I am having trouble guessing what is behind the gear and I see that there are holes in the gasket for something.

Yes. There is a hex bolt or countersunk screw under there depending on whether you have an alloy or fibre timing gear. Just rotate the crank until the marks line up in both gears so you can put it back in the right place.

That's a great bunch of photos and a wealth of information for anyone building one of these up. You probably covered this somewhere else but what is the finish you used on the exhaust manifold?

WOW! Those are some very exciting pictures and helps me understand my engine much better. As I mentioned earlier I am redoing the gaskets, clutch and motor and transmission mounts. I am starting at the front of the engine and was looking to see how and where you put in the rope for the rear main seal. If you have a picture of this it would be greatly appreciated.

You can kind of see it in those photos. Look for photos - "Main Cap Bolts" and "580 Number"

Er...there is no 'rope' for a rear main seal.  There is a drain tube which drains the leakage back into the lower pan.

And..before you put the front end back together, make sure the thin phenolic thrust washer is in one piece in front of the camshaft..or get a new one from Dale Cooper

My engine package came with two bags of I guess what is called yarn packing for the rear main seal with instructions on how to install it. What is this yarn packing for?

Uncle Josh

There are round holes drilled in either side of the rear main bearings, and cross drilled in the front main bearing.  Pack this yarn in the holes a little at a time with a punch and hammer.

Thank you Uncle Josh. I haven't got to the rear of the engine yet so I am not certain as to what I will find. How much of this yarn will I be using?
