Ford Workmaster 641 Hydrolics

[sreding1204]

We have a 641 Ford Workmaster tractor that is loosing pressure for the hydro lice/ they stopped working. There seems to be some sort of add on part where we're assuming there used to be a lever to control the height of the arm lift (we read this in the original manual). Anyway, we need to check the fluid level before I guess we assume the pump went out? Not sure where to do either as the manual didn't seem to cover this as far as we can tell. Any help appreciated.[/img]

The hyd pump is down in front of the light switch, front of the brake pedals. A xx1 model tractor should have the better rotary pump, not the
older vane pump. They can loose prime and need to reprise them.

The hyd plate which has different routing for hyd bits is under the seat. There are several different designs on this, one way one valve, to two
two way valves. A picture would sure help of where the hoses and levers come out.

If it is so modified that the three point controls are removed, it would just be wild guessing as to what is really going on, pics would really help.

Thanks for the advice on the pump location Paul. Found it. I'm having trouble loading pics from my phone on here so will have to do so tonight. Some clearer information on the issue though is that the hydraulics work in position control, but won't work at all when we turn on the draft control lever next to/under the right of the seat. The draft control worked a few times then all of a sudden stopped working entirely. Wondering if the problem lies with this lever or the adjustments you spoke about under the seat instead of an issue with the pump? The fluid level is full- we checked that too.

I will also try and post pics from my computer tonight instead of my phone- might have more success.
