Ok ya i gather i had the wrong diagram i think it was for a 743 and it has a sleave over the filter. But anyway i got it back together tonight and after filters and fluid change ( which wasent done all that long ago.) i ran it for a bit and found now it seems to make noise just moving the boom...

So I may have been looking at the wrong diagram, I found another parts diagram online and it doesn't show the sleeve over the filter. still if anyone has had one out and knows ya or nay let me know.

So lately i have been having a issue with my 731, after dumping the buck and lowing the boom while driving ahead it seems like the the pumps cavitate and then the drive jerks and growls for sec and them alls back to normal and it only seems to do it while operating the boom and driving at the...

was thinking of phoning loader parts source, i have phone around to a couple local Vickers suppliers and no luck so for and the bobcat dealer can only get the Rh wear plate and i need the left. next question i was going to fill the system with bobcat oil for hydraulic fluid, is there any issue...

so i kinda feel like a idiot. i cleaned the housings really good and found the numbers under some paint. while i was cleaning the wear plates i noticed on the weak side that theres a wear groove all the way around in line with the valve openings, to deep to sand out so its gonna get new ones...

ya thats were i going next if fixing the wafer plates dosnt help. need the seals to put the pump back togther.

So i finally had to sign up and post, i have found just about every piece of info i have needed yet on this forum so i will start with a tanks to every one. i just bought as 731 and it runs great for about ten mins then the left side starts to get weak and eventually the left side has no power...
