Does anyone know sizes of lift cylinder seals? Seal kit costs something like 70euros for one cylinder here in northern europe. I could easily pick up seals from hydraulic parts store , if i just would know what to buy. Machine is located at my summer cottage and it would be nice to have new...

Hi. I was suddenly having problem with lift and tilt they were slow and down on power. next time when i was driving and testing the problem were still there. i hooked up my backhoe attachment to feel is it low on power too and i think it was. after some digging and driving everything went back...

I suspect something like this: http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=54&frmView=ShowPost&PostID=61257 See that picture attached on that post. i know it is different valve , but i´ll bet that your aux spool has something broken inside or it has been assembled wrong. timing is...

Hi. I am not sure , but i think that your problem might be inside that valve which is controlled with that right lever when moved to left and right. I´ll guess there is spool inside that valve , and your problem might be there. That spool provides your auxiliary pressure and return flow.

that deutz engine is very reliable, way better than kubota. i suggest that you change new fuel filter and send injectors to diesel shop, so they can check them. bad injectors could make it hard to start and cause lack of power and also smoke from exhaust

hi walio123! i tried to email you , but didn¨t work. can you send manual for me? i have bobcat 641. thanks.

ok repair is now done. but the design of axle is quite crappy , you need to take bearings off too to change seal. but anyways you will need somekind of c- chaped rings to push axle seal in place , we did them from very strong alloy plate. and be careful not to damage the dust lip of axle seal.

thanx for your quick reply. the block is same side than gas lever and big hose goes from there to the pump, so no bronze filter and thats the reason why i couldnt find it from parts book. i guess i need just check that there are no suction leaks. maybe it just is a bit noisy specially when...

we are repairing left rear shaft seal and there was little bit hyd oil disappearing somewhere before this shaft seal repair. when we started this repair today there was maybe little too much oil in chaincase but not a lot. we tried to run machine jacked up and no leakage spotted from drivemotors...

Hello! i quess we got same engine in our 641 , there should be somekind of cold start solenoid in it, but it has been removed from our machine and there is pull/push cable attached to lever in pump where that solenoid should be, and when we cold start it we pull handle in cabin and starts really...
