Hi all
I recently blew up the electric clutch in my Ransomes mower
Putting it back together with a new clutch and a new PTO shaft which was either a- damaged flying off, or b- bent beofrehand, or c- both.
There is a 1" intermediate shaft mounted on two pillow block bearings. This is fed by a coupler from the engine and the opposite end has the electric clutch feeding the PTO to the deck.
I decided to take this shaft out and have it checked by a machinist friend of mine to make sure it was OK as well. After checking, he found it was within .005 or better so we decided thats probably close enough. Problem is that one of the pillow blocks was stuck on the shaft and I broke the casting trying to press it off.
I went to Surplus Center and got two new ones. Now I discover that the bore thickness is 1.339" and the old ones were about 1.1".
This added thickness pushes the end pulley too close to the engine so the coupler won't fit.
Looking at the old bearing, the insert says [ FAFNIR YA100/R ]
The remaining specs: 1" bore, 1.437" height to center of bore, 4.134" between mount holes, 5.512" length at base, w/ 3/8" (or 10MM ) mounting bolts.
Can anyone point me where to find a couple of these?
Thanks!
