That's a great observation Sam, at least it looks like he's got plenty of room to fab in a pillow block.

I thought about that and have pillow block bearings on hand for just that purpose. Until I saw where a Wheel Horse tractor had the same Sunstrand belt driven. Perhaps that unit had different bearings?

The Toro c-145 I think is belt drive hydro. 1980 vintage. I'm having trouble finding a definitive diagram for the c-145, but what I have found looks like it's driven from the other end, the rear output side in our situation, where there is a better bearing I think.

I have to look at the charge pump bearing again to see what it is. Have one in the bin.

I will be watching this, The C145 had a sundstrand or a Eaton trans pump, but they will not work in a cub, you may want to use a Simplicity one.

Models 01-14KS01 and 01-14KE01

Nice to see you in another project. We'll be watching...:bigthink:

No. Not planning to use one. Just commenting that they were belt driven. In response to Sam Mac's comment that a Cub hydro input shaft can't take side loads such as from a pulley mounted to the shaft. I was noting that the Sunstrand on other tractors is belt driven.

I looked at the charge pump, it has a roller bearing in it. I think it will be fine with a pulley on the input shaft.

I've got the drive set up complete. Next need to put the starter on the engine, set up the fuel tank, carb and electrics. Then test it out before I go any further with the main frame, circle, blade, etc.

Your call. :biggrin2:

Charge pump has roller bearings, or, maybe due to size are classified as needle bearings, both good for radial loads. they look similar to those used in the axle housings.

Some progress. Focus now is on getting the engine configured to run, extending choke and throttle cables, basic wiring, etc. In process of fabricating the front panel to hold the forward end of the hood, which will include a solid panel to stop hot air flow toward operator. Once engine is in running shape, I'll put the four rear wheels on and go for a test ride.
