I recently was able to purchase a T&M engine that was an unfinished project, and is completely apart.
All of the pieces seem to be there, but I'm unsure about the water pump.
I have the shaft that connects to the crank collar, and the pump body, which has a beveled valve in the top end, along with a plug at the very top.
The shaft goes through two sets of packing.
Does anyone know if there are parts missing, or does the shaft movement up and down provide enough pump action to move water?
Hope the attachment and post load up this time.
Thanks, would appreciate any help.

If there's only one check valve in the pump you'll need an inline check on the inlet side. Here's a sample on ebay.

Thanks a lot. Was afraid that something internal was missing, and I imagine that original parts are pretty scarce.
I don't know the year of the engine, but from examples I've seen, it's one of the earlier ones, although it does have a bolt-on cast exhaust manifold.
Don't guess there's any way to date it for sure?
I'll try to upload pictures of it sometime tomorrow.

Amazing how close that water pump resembles a DEW water pump. If the engine was mine I would take that rod out of the flywheel and never put it back. Wrist or finger breaker if engine kicks back. Just use flywheel to start engine.

Here is a photo of where the valve should go that JB is talking about.

That's the exact engine. I've looked it over and don't really see anything that would keep it from running.
It seems to have good compression, and outside of new gaskets/plug, etc. believe it will fire up.
I agree about the flywheel handle-looks like a disaster just waiting to happen, huh?
Can just imagine a shirt sleeve/pants leg getting caught.... with the weight of that flywheel don't think it would stop anytime soon.
Do you have any clue as to what year this engine is?
If I'm lucky enough to get it up and running, will post pictures of the finished engine.
Beautiful job on the picture of the engine you posted.
What kind of set up do you have on the carburetion?

Thanks,

Truman

I would guess your engine was probably manufactured sometime before 1909. Indications that it is a early 1900 engine, small threaded inspection hole, does not appear to have any balance holes in flywheel or counter weights on the crankshaft. I believe that is also a early style exhaust manifold with the exhaust hole coming out the back and not the side. Then again that may have been an option that was offered. What are you going to do about the broke hub area on the flywheel?

The carb on the DEW is a lunkinheimer with throttle control lever.

Thanks for the information.
Do you think that the muffler had an internal pipe?
There's not one thru
it but there seems to be threads both at the top and bottom for one.
The chunk out of the flywheel hub doesn't go into the inner portion,but have thought about welding it back up flush for safety.
Any ideas or advice?

No muffler shown in the photo. There is an exhaust manifold/condenser. See pic below, there should be a small pipe inside the manifold with very small pin holes that allow water to come out. The problem with the flywheel maybe getting the gibb key tight enough to hold the flywheel on.
