Simplicity 7016H Won't move

[DRay831 0]

I have just finished (I thought) 4 months refurbishing my Simplicity 7016H. It was dismantled, cleaned, sanded, painted, given new decals, and reassembled. I did not remove the hydrostatic drive, just pressure washed it, as it operated as designed. Did not need to be rebuilt. But after putting it all back together, the venerable B&G 16HP started right up, but the hydrostatic drive is not transferring power to the wheels.. The shafts out of the beveled gear box are turning, and the drive belt to the transaxle is turning, but no power forward or reverse. I have pulled and cleaned the switches on the free wheeling lever and topped up the fluid level with Dexron.

Any ideas as to what would happen with 4 months of inactivity that would cause this malfunction?

Are the buttons that allow the tractor be pushed with out the engine running stuck?  I’ve had mine stick before.

Are you able to move it when you push against it?

It free wheels easily. I pulled the pistons that hold the free wheeling buttons, soaked them in penetrating oil and shook the ball bearing and made sure the buttons moved easily.

With the free-wheel pins out, does it move when pushed or no?

Pump shaft key sheared? Pump pully turning the pump shaft?

Does it move the wheels at all  if the rear of the tractor is blocked up off the ground? If it does then problem may be a sheared key in the differential, axle tube, or drive gears.

 

Just pitching ideas out from past experience....

Do you see movement in the axle tube?  Differential collar may be disconnected?

I am sure I sheered off my axle key, well almost sure.  Is it difficult to pull the axle and put in a new key?  And do you know where I can find a acritical that explains how to do it or a video?  Thanks Much Don
