I have a problem and can't figure it out.
I bought a Derby three wheeler which was made by Ferris. They look identical.
I remove the PTO clutch from the mower. And now what to replace it.
There is no diagram, parts look up just a manual (operating) for the Derby. However if you look up Ferris Procut S you will find what sure looks like the same unit.
It has a briggs 20 hp Vanguard engine on it.
The Ferris diagram shows a part number BS-5043625SM (1"x1.75") and a BS-5042304SM (1.13"X2.00") for the same part on Ferris diagram.
This is a spacer that fits between PTO clutch and the Belt pulley which drives the blades.
The problem..... know what a spacer if for, but which unit should be purchase. What exactly does this bushing function as.
 
More stupid questions. I am assuming that the purpose of this spacer is to fit against the pulley right above that clutch and bearing which is on top of the clutch itself. So that when the clutch is engaged that pulley turns.
The critical connection part here is going to be the bearing connection to that spacer that I've been talking about. Again, I'm assuming that the spacer must connect over the engine shaft (ID) and on to the bearing (inner steel ring) It must keep that bearing free to turn.
Am I right here.
 
Lets start with the actual model number of the mower starts with 590. there is 9 versions of the Procut S.
 
I probably didn't make myself clear. I have an old Derby TW2061 not a procut s ferris.
No diagrams , No parts books for Derby. Which was made by Ferris.
