    259B broken throttle pedal

    Serial Yyz00687 Anybody have the part number handy for the throttle pedal. I have accumulated quite a few cat pedals over the years whenever I think they can be repaired and I have already bought a replacement. They come home and get soaked and if they free up easy enough they get thrown in the...

    Cat 308 swing problem. I bet someone can save me a step.

    Vgg803307 The machine was free swinging to the left (or CCW, if that is the way you like to think about it). Kind of figured that it was one of the swing cushion reliefs. But I don't generally commit to a hunch, so I checked a lot of things to make sure. In the end I swapped the swing...

    Zx200L-3 main relief question

    FF01U1Q203192 Had to replace a main relief valve on this machine this week. I am a little unsure the adjustment. I understand the high side relief, but the low side relief is a bit unclear in the tech manual. Perhaps I just got tired of flipping through chapters (never been a fan of how...

    Zx200LC-3 no hydraulic power after repair work

    FF01U1Q203192 Had this machine torn down for about a week to replace the engine rear main seal and the "transmission" coupler on the flywheel. First time for me on this machine, but a job I have done about twenty times before. After I bled the pumps and fired it back up I have very little...

    MB crusher bucket case drain question. Can't really decide if it id dumb or not.

    Client of mine picked up a second crusher bucket to run on his Hitachi 200 and 225. I plumbed the machines for his old MB 70.2 and that only required a #8 line for the case drain. The new (second hand) unit is an MB 80.1 (I think). It comes with a #12 case drain line. I checked with MB, they...

    289c front track frame repair

    I had a tensioner (I thought) problem on a 289c this week. When I removed assembly I found the rod was extended out about 4 inches with no grease coming past the seals. Looked in the front frame assembly and saw that rod had punched a hole through the alignment pocket.

    Excavator hardware questions

    Trying to figure out the feasibility of replacing the base edges (to be honest, until five minutes ago I was pretty sure that the part that I welded adaptors to was called a mold board) on a couple of buckets. First bucket is (I think) a 24 inch bucket on a pc 120. Someone tried to repair it...

    JCB 712 identification and parts support

    I'm gonna say straight off; no idea of the serial number. The data plate is missing. Anyone know if it is stamped on the frame somewhere? Is it possible to reverse engineer it from the engine or trans data plates? Anyway... One of my core clients found this unit and was told they could just...

    BTI 925 hydraulic breaker

    For a few months, I have had a BTI hammer partially torn apart in my work yard. I have posted about it before. I think the thread was on this part of the forum with the title, "looking for the right mill bit". You can look at that for more info and pictures. Long story, short: the main body...

    03 isx gear pump fuel leak

    This truck left my yard yesterday morning after dealing with a fuel delivery problem. I don't know how to link to that thread. It was called https://www.heavyequipmentforums.com/threads/liftpump-testing-on-cummins-isx.104512/post-1173000 Maybe that's how. Anyway, he called me this afternoon...

    Liftpump testing on cummins isx

    Anyone know how to test the performance of the electric lift pump on an isx? I see the test port on the high pressure pump, but kind of think that just tests the high pressure pump. I do not have the esn right now, I apologize. Truck rolled into my work yard this morning and I cannot get it to...

    Have to re deck a low boy

    I had to get a loaded dead dump truck on a low boy this afternoon. With the lack of steering I couldn't keep it on the rails and ended up turning about 25% of the decking into kindling. I don't think that I had this forum to ask last time I had to re deck an equipment trailer. I am a little...

    T800 Cat C 15 died on road.

    I don't really see a lot of tractor or tandem questions here but thought I might ask a question or two anyway since it is after hours for my cat dealer. I don't have the serial number in front of me but it is an MBN prefix. Driver said it was like he shut off the key. No restart no smoke...

    Cummins 5.9-P injection pump question.

    Had to replace a shutdown solenoid on a morbark chipper last week. The original was mounted on the injection pump, the replacement mounts to a bracket between the lift pump and the block. It also uses a different shutoff lever.

    Rear main seal installer Hitachi/isuzu

    I need to do a rear main on a ZX225. The installer is called out in the shop manual as 5-8840-9025-0. Quick internet search doesn't come up with any matches. I probably have the machine serial number in the truck, but the engine info would have to wait for me to get back by the machine. The...

    Gradall 534D-10 0366439 I need to raise the boom on this machine. First, in order to get to the Cummins data plate on the timing cover, more importantly to work on/or replace the engine. I have used electric portable hydraulic pumps to raise booms on other telehandlers. A couple of sky traks...
