Manitou 932 No Drive Not Electrical

[RichWCF]

We have a Manitou 932 (1999) with no drive forward or reverse, I have checked the usual wiring problems.

The power to the solenoids on the gear box is good and the solenoids operate with a good sounding clunk.

So I think it is probably an oil pressure problem. caused by pump or relief valve maybe?

Does anyone know where to pressure test and what the pressure should be?

Or if anyone has had this issue?.

Thanks

Are the Hydraulics still working?

If it stopped working instantly it could have stripped the splines out of the Torque Converter - Torque Converter Pumps tend to wear out gradually unless it has seriously broken up internally.

Yes it stopped working instantly I wasn't driving so don't know if there was an noise as well.

Looks like I'll be taking out the box and having a look?

Hydraulics are fine but the gearbox pump and the main hydraulics are separate systems.

What was the problem?

Thanks for your help.

Turns out it was a gear linkage felt like it was going in gear but wasn't quite there.
