    Fluid transferring to front diff through piston seals

    I have been working on a 950H(K5K) Cat loader that keeps transferring hyd oil from the brakes into the front diff. I have checked all pressures and tried new pistons but no luck. I believe the 325-3780 D ring brake seal is the issue. When this seal is in the housing, it barely protrudes out...

    480f brake issue

    Hello all! I searched for this info in the threads and couldn’t find it. Google has little to say about this problem as well. I’m currently working on an old 480f. I’m the jack of all trades for a local landscaping company. I’m 90% sure this thing has had no preventative maintenance in the last...

    Cat 988F Braking issue

    Hi all, Just after some ideas in regards to a braking issue on my 988F. If the brake is held on for a short period of time I am finding that the warning horn goes off and the park brake applies itself. I’m sure there would be a leak in the system somewhere, either the valve group or accumulator...

    555e bleeding new master cylinders?

    I ended up putting 2 new master cylinders in my 1998 Ford 555e because one was broken and the other quit working. I bled them per the manual, "open bleeder screws until oil comes out", by using the L/R bleeders on the rear end. I had them open for about an hour and had a small drip coming out...

    MF50? Model? Year? Steering? Brakes?

    I think I just bought my second MF50A but I am not sure. Here is the tag: It predates the 1969 9A63158 9A87324 serial numbers and I have no other source. What is it? Two big problems, power steering and brakes. Filled the power steering and it is churning, so the drive is connected, but...

    580ck brake shaft seized

    Hello everyone. I purchased a 1970 580ck loader/extendahoe with a Gannon. I don't believe the previous owner did maintenance on it and I want to make it safe to ride before I rebuild the hydraulic seals and get to work.

    TS14 stuck brake shoes on anchor pins- can't remove wheel

    I'm sure this has been dealt with many times, especially on the truck side, but the brake shoes are stuck out against the drum hard. Can't even bar over the driveshaft to the axle. Grease worms have been working their magic on the anchor pins. I have the slack adjuster/S cam backed off and...
