thanks for the reply
thankyou for the reply, with regaurds to the fuel tank i can see othesr before me have attempted to sort that issue out, when i first got her i would have to bleed the fuel system out and would get around 10 mins running time before it would need doing again, someone had added another fuel pickup line that went down the fuel filler pipe and then to the fuel pump, i eventualy went inside the tank which was somewhat full of shi*, after giving it a serious clean i found a hair line crack in the original pickup pipe where the bracket is welded to the pipe that then fixes to the tank housing, the crack would let air in and then cause the fuel system to fail, if i had a full tank and it was above the crack it was fine but as soon as it dropped below which was around half a tank it would cause problems, i havent yet sorted it out as i cant remember where i put the tank entry plate, so ive been using 25 ltr clear tank placed on top of the machine, it does around 4 hrs constant use and i can see when its low, ive had all sorts of problems here with fuel, it eventualy was water in new fuel i was buying, the owner of the fuel station band me from going there when i complained about the fuel, i took a clear brand new tank to him, we filled it up with fuel, i then froze the fuel tank which froze the water in the diesel, drained the new fuel back out and showed him the remaining frozen water in the tank, all of this was done with him and he still said there was no water in his fuel, so i now place my fuel drums in a old chest freezer for a day, drain of the diesel and then i dont get water in my fuel system.
what exactly are you refering to you when you say remove the filter housing and do it in a vise, where is this part located, i had new oil filters replaced 2 yrs back but it hasnt done much work since then, run half a dozed times really but i will change them.
i do have a slew brake but im told its a hydraulic one not electric, but worth checking, i understand the pumps are poo anyways but after she has warmed up and used for 10 mins id have no problem usualy, it didnt cause any problems in the summer so i was thinking maybe too cold.
i also had slow tracking a few yrs back and a jcb fitter said to take the track motors off and drain the housing as when the seal leaks the fluid bypasses and slows the tracking down, i seem to remember doing this and it all ran much better hydraulic wise, i may do that again.
im slightly fortunate that what i paid for her 4 yrs ago would still leave me in profit if i were to scrap her at todays scrap value but i do like her a lot, and then you have to find another which is unlikely.
i have to say its been ultra reliable since i have owned it, other then tinkering she hasnt failed in a big way, burst hose last week and the intitial fuel issues but other than that just fine, oh she did burst a water hose cos of sticky thermostate so i run it without one now to be sure it cant happen again.
can a pump fail that quickly or just slow in performance, moving the boom in and out and tracking around is still the same so i would have thought the whole perfromance would be effected not just slewing.
ive got some more fuel to freeze and bleed through again so i will change the filters if i can find some and get her well hot and see how she performs.
another reply would be most gratefull
thankyou in advance.
ps nice pic of the 814 on the water main, mine is nothing like that in cleanliness, she was a machine that was repaired at a jcb outlet, new slew motor and ring, repalcement perking 6 cylinder turbo uint, cush drive to pump, recon track motors, welded up rams as they had cracks in, and then some kids trashed it, i bought it and got her running which brings me to the current day, cab is totaly gone but i have a replcement with all the glass etc, just never fitted it, i have the super wide tracks for the lake dredging which is what the original owner was using it for, all the pins and bushes are very good all round, she just needs a bit of time to sort her out, but that time never comes does it.
cheers
