when i first started trying to figure out why mine might be running "slower" - many (as in this thread) indicted the filter might have hose debris in it. my filter was super clean, so i'd recommend not buying a new filter untill you pull and inspect your old one. as some other have said i...

I can take a pic, give me a day or two, i just guessed (wrong) and installed it in a plug on the top of the control valve body that i thought wasthe suply side (its still on the wrong side, haven't had the time to move it). i believe i just need to move it to another plug on the other end. the...

was out running my crane and got some of my RPMs wrong in earlier post, mine runs on the governor at 1500 rpm.

might look into adjusting your governor on the fuel pump to govern up a bit. the TM gives the correct RPM, my memory, I think it should be about 1700 rpm, I also remember a warning about not running the crane PTO at less than 1500 rpm, but again check those numbers. when i'm on the crane my...

on the governor (crane PTO engaged) my engine runs at about 1700 rpm can't remember exactly, not sure where the PTO takes off the transfer case (how its geared) - but TM has you put it in 5th which is basically automatic. I've never heard the transmission "shift" when on the governor running...

I have not solved the issue, did drain the tank and change the filter - it was clean. installed a pressure gauge - but put it on the wrong side, so no info on pump pressure. must drain the tank again to move the gauge. that may indicate a weak pump. or if I have a collapsed line between...

so how messy is removing the hydraulic filter, the tm indicates it auto seals from the tank??? or do I need to empty the tank first?

Simp5782 I looked over the hoses last night, just squeezed them. all big return lines were hard as rocks....will try the hammer trick tonight. one question - the TM indicates that when you pull the hydro tank filter it self seals the line.... but what ever is in the filter i assume will...

thanks hadn't thought of a collapsed hose... will check that out.

Back ground info I noticed my crane (M936A1) seemed to be running slower (hydraulic operations) yesterday, not sure if governor RPMs are down a bit or not, was running at 1500rpm yesterday, can't remember if it used to run just a bit faster (1600-1700?). could 100 rpm make a noticeable...
