front pto

[ricknrandy]

I need the splined sprocket that mounts between the crankshaft and the front pump with the double chain. This is the sprocket that goes on the splined shaft that bolts to the crankshaft and connects to the extension shaft with the double chain. Any ideas where I might find one?

Welcome to TBN!!

Since you have a Yanmar tractor, I suggest you post your question in that forum. If the part is available, I'm sure one of those folks can give you some good sourcing info.

It's tough to help without the make, model and year of the tractor in question.... Photos are a great help also.

I'm not sure what your sprocket is like, but I replaced the chain coupler components in my YM240 with parts from surplus center. Mine weren't splined, though. On the pump end, there was a 3/4" keyed sprocket. The shaft in between was solidly welded to two sprockets, and there was a hub that bolts to the crankshaft with another welded pulley. As others have mentioned, some pictures and dimensions will really help.
