    JCB 426

    Okay. Today I did a pressure test and it seems that is the correct pressure. Now I think it must be worn brake pads. I think I will remove and open one side up. Does anyone know how thick the pads are supposed to be?

    JCB 426

    I purchased a JCB 426 2008 and when I drove it off the truck I notices that the brakes are not very good. I contacted the gut I bought it from and he said, they never had a problem. It will stop but nothing like my Cat or Komatsu. Trying to test the pressure but really I don't see much pressure...

    Stupid question, but have you checked the transmission level while idling. My old MF-70 did the same thing,,oil was too low.

    WA320-3 transmission problems

    I'll check that and get back. Thanks, now I'm remembering that when traveling and if I push the brakes to slow down, loader take a long time to get back up to speed. I'll check the brakes. Thanks again.

    WA320-3 transmission problems

    I haven't tried a gauge yet, I have oil flowing through the cooler but I will check the pressure with a gauge. This is a 1996 model and I can only find 3 filters and strainers. I've changed them all a couple of times. At one time when I changed the filters, the little pilot strainer was...

Sometime after starting the loader and putting it in forward or reverse it wont move. I have to rev the motor and it will move slowly, then...

    Wiring diagram

    Does anyone have a wiring diagram for the alternator on a 720B Volvo grader 2006? I have 3 wires connected to the alternator and I need to know where they go. My voltage has dropped to 19.3v-21.6 volts and I think the alternator is toast. The voltage drops if I rev the motor and if I remove the...

But if you raise the bucket you can swing the machine by pushing on the bucket with your hands. Anyone see this before? We are starting to remove the swing motor. Hoping it's...

    O rings

    Sorry I said piston but I mean the sleeve (if you can call it that) before the piston. It looks to me like it just floats in the cylinder.Anyway, that o ring is the same as the one on the piece you remove first when you remove the bolts.This was where I changed the seals. Don't know the names of...

    O rings

    On my cylinder the o ring on the flange and between the outside ( where the bolts are) and the piston are the same.

    O rings

    Thanks everyone. The seals that where leaking were the ones one in the outside. These seals were the only seals in the kit to fit. I just finished to change these and everything is back together. Everything is tight for now, I will see later when I go back to work. If it happens again I will...

    old loader slow- to- go now that it's colder

    Be sure you check the oil level at idle. If too low it will not have the right amount of power. My old MF-70 was the same as what you said yours was. The guy I bought it from had the wrong oil and not enough. The machine would not even move when the weather got cold. Changed the oil and I had to...

    O rings

    Thanks. No its a genuine komatsu kit, but its a over seas version PC-200. The kit cost over $400.00 and only half the seals will fit. WTH.
