Z won't move

[gregjo1948]

working on an older IS3100 That I had to do some engine work on. Engine is repaired and running fine, but the machine won't move. It's been sitting since July 2022. Has the correct fluid in the pump reservoir and the releases are in the right position. It was driven to where it is sitting now and moving as it should. Would appreciate any help, gregjo1948

Just to be sure, check the belt....

The belt is fine. It's easy to see both cooling fans spinning.

have a close look at the belt & pulleys.
No uncommon for the belt to pop off the pulley and sit between the pulley and the fans

It would need to be a trick belt to get between the pulley and the fans. It is under the pump mounting deck.

Just for grins try purging the system of air.

It would need to be a trick belt to get between the pulley and the fans. It is under the pump mounting deck.

Especially if the IPL I just looked at is right as it had the fans on one end and the driven pulley on the other end.

Anything is possible with older units sitting for long periods.

Now if the engine was removed double check the engine's pulley didn't lose the key just to be clear. Also check that tensioner idler arm is free moving as it could bound up from sitting a long time allowing the belts to slip.

The pumps are both turning as they should. They are not running the drive motors.

Did you or someone by chance open the bypass valves on the pump while you were working on it?

 

[gregjo1948]

the bypasses are both closed.
