replacing air compressor

So much misinformation.

A stroker has a longer throw due to the crankshaft AND the pin is higher in the piston, resulting in the piston top dead center being the same (or higher if there is space) and the bottom dead center being lower resulting in greater displacement.

If anybody had checked the specs of the 550 and the 750, as listed in their respective manuals, you'd see that the only difference is the stroke and the placement of the pin in the piston. It's right there in the book.

 

good that you showed up 8 years late to share this info/

 

Welp, sometimes people are out looking for the info and the internet machines don't give as much weight to age of esoteric information as you do. So it's good for it to be correct.

 

I realize that this is an old post, but this info still applies -- and may be useful.

There is a retrofit available that will let you replace your TU-750 compressor with the higher output BA-922 compressor. I am presently doing this on a 12.7L Series 60 -- the re-manned compressor cost me $1,500 and the fittings kit cost me another $220. The fuel pump is different, and the new one cost me $450. So, no -- it isn't a cheap retrofit -- but it eliminates one point of failure on the Series 60; the drive extension that most TU-750's mount to has a nut on the inner drive coupler that likes to loosen up and leave you stranded with no air and no fuel. The BA-922 mounts directly to the back of the front cover, eliminating the drive extension, and runs directly off of the engine gear train.
