Restore Rebuild Ford CL-30 Questions re -Coupling

[Lynn Perkins]

I just joined after viewing pictures posted on the rebuild of the CL-30 by Don. I am getting together all the parts to install a 4 cylinder Wisconsin into one of my Ford CL20. My CL 20 has a 7/8" number 13 spine on the Hydrostatic pump and my Wisconsin has 1-3/8" straight shaft. I found a Lovejoy L-100 with 7/8 number 13 spline from Surplus Center but have not found a 7/8" splined half sprocket to match the 1-3/8" engine shaft. The parts catalog for the CL-30 shows a double chain coupling. I found an engine to Hydostatic pump mount bracket at Hydro-Mount. I would rather have the chain coupling to get the higher Hp. and torque rating than the torque rating for the L-100 coupling. What brand of chain coupler was used between the Wisconsin engine and the Hydrostatic pumps on either of the two Ford CL - 30.

Hi Lynn,
I would also like to use a Lovejoy coupling if I could find one for 30hp. I still have not found out how to disconnect the chain from the two coupling sprockets. I reckon I'll just torch the chain off so I can remove the pumps from the engine and learn how to reassemble it later.
Run a Google search for roller chain coupling to get an idea where to purchase new parts. It takes a #50 double row chain and 16 tooth sprockets.
Remember, the various models V4's have different base to shaft centerlines so make sure your pump forward attach point has enougth room to align.
