    I'm looking for a source for a parts manual, JCB 320T tracked model. I'd prefer a hard copy but will consider a readable .pdf file. JCB isn't known for customer access to self help. Ideas? Thanks

    Hitachi EX Hydraulic Pump Control Problems

    I have a EX100-3 with a classic slow pump control situation. It starts with everything operating at about 50% speed and gradually slows down to dead slow. I've checked the wiring and the control modules are both blinking red. The engine is operating fine and in checking the pump pressure, I get...

    Hitachi EX100-3 slow hydraulics

    The hydraulic functions in this machine operate fair when cold but slow down dramatically as the system warms up. If this happens there's a reference in the operators manual to rotating the lower cover on the hydraulic pump and setting the Pump Swash Angle. I've attached the pages from the...

    Hitachi EX100-3 Electric Relay Questions

    On the EX100-3 wiring diagram the EC Motor Relay should have constant 24V power at #1 & 3 contacts of the relay. I have voltage at the 5 amp fuse but nothing at the relay.

    JCB 320T Track Skid Loader-Hydraulic Leak

    I have a JCB 320T with a hydraulic oil leak under the plastic hydraulic tank. I will need to remove the tank to locate the leak.

    Hitachi 120-5 : Auxiliary circuit pressure relief

    I have a EX120-5 with a auxiliary circuit for a thumb, hammer, etc. I need to lower the operating pressure for this circuit to 2500 psi. I've done this on a Ex120-2 machine and it's straightforward. The control valve on the -5 models is different. I thought I located the relief adjuster on the...

    I have a grey market EX120-5 with a 4 position Kawasaki brand pattern control changer installed. Position "Y" is standard "Cat" control but the other three K,M,H are Asian standards we don't see in North America. I would like to modify it so one of the positions is "John Deere" style. Is anyone...

    I'm looking at a Hitachi EX120-2 machine. It was built without a auxiliary circuit or valve to operate a thumb, etc. Other than buying a valve to add to the valve bank, are there any other issues to deal with? I'm expecting to need a valve, steel piping from the valve, misc. hoses for pilot...

    I have a 1995 EX 120-3 with about 8000 hrs. Recently when it gets warmed up it starts to bog down & then start missing under a load. The more I use it the worse it gets until it misses to the point of quitting. It will run ok at an idle or max rpm without a load. If I leave it off for 10-15...

    I bought a Cat 215 excavator 96L02738 built around 1980. It originally came with a 3304 engine but that was replaced with a 3204 DI 10X engine later. The later models (14Z, 61Z, 57Y, 95Z) had the 3204 engine. I need to buy a service/overhaul manual. I like to buy the later manual w/ the 3204...

    Samsumg Excavator parts & sevice help

    I am looking at a 96 Samsung SE210W excavator. I know parts availability is terrible. Volvo is less than helpful and they say maybe if a part # will interchange then they can maybe supply. I've checked both US & Canadian dealers. 1) Is the 1996 pre-Volvo purchase timeline worse for parts? 2)...
