Sam and to all,

Sorry if I ruffed your feathers but no one believes me that this is a direct bolt up with a new pump adapter plate.

I now have the motor mounted to the frame and temporarily installed the drive shaft. It fit like a glove. Once bolted to the pump adapter plate, I then checked end clearance to the motor adapter and there was about 1/4" clearance to end of shaft. This gives plenty of clearance for forward and rear end play and still having a full set of splines in each CV joint.

The shaft that I used was from an 1862 which is 18 inches long (shaft only). The 4 models that it fits are 1541, 1860, 1861 and 1862. This complete unaltered CV joints and drive shaft bolts directly up with the pump adapter in my drawing. Your pump adapter to these older pumps may be longer or shorter. You'll have to find out if it works with this shaft.

The fan will need to be trimmed to a smaller diameter but that is minor modification

I'm attaching picture of my proof of fit.
