    Cat 955 Transmission Not Shifting

    Found two o-rings needed to be changed. It's back up and running

    Cat 955. Left side track, steering works some days, majority of the time steering does not turn

    Posting the pictures of worm out pads and drums. I figure once in a blue moon when it did pop out of the groves, it would grip and begin turning correctly. New pads are $2k. It took a while, and lucky to find used pads at 90% off a machine being torn down.

    Cat 955 Transmission Not Shifting

    Not moving out of neutral, starting the engine multiple times and running it trying to switch gears. Ran the engine for 15 mins to see if pressure build up, but no luck. Transmission linkage is straight, not loose. You can see it move the lever on top of the transmission into each of the gears...

    Cat 955 Transmission Not Shifting

    I'll start tracking this down and also purchased o-rings. Also found this on the internet describing the operations in how it works. Am I correct, is it "valve (13)" that has the spring that is pushing the level back to neutral because I do not have enough pressure...

    Cat 955 Transmission Not Shifting

    Test. The pressure gauge on the transmission pump reads 100psi at Low Idle and 150+/-12psi on High Idle. What does that mean, lost flow? What do you look at next? Did the pump run dry, if so, can it be primed?

    Cat 955 Transmission Not Shifting

    Another comment, I drain, replace the transmission oil with new with fluid at correct level. While the transmission was floated/lifted, it was slant to get it in/out. Could oil drain from the transmission oil pump, removing pressure from the spring? Possibility another reason why this is...

    Cat 955 Transmission Not Shifting

    It's a 85j* series. The video shows the resistant in the shifting while holding the lever. It gets harder, and harder when shifting through all the forward or reverse gears. It springs back to neutral when releasing the knob at any of the gears. I also show the control linkage following the...

    Cat 955 Transmission Not Shifting

    After putting everything back together on the Cat 955L the transmission will not shift. I tried uploading a video to show you. Instead attached a picture. Running or not, use the shifting lever from 1st to 2nd to 3rd, and it is hard to pull. You have to give it a little force. Just it will not...

    Cat 955. Left side track, steering works some days, majority of the time steering does not turn

    Figured out the brake was at the end of the adjustment. The machinic over turned the adjust screw. The reason why it keeps spinning is the threads of the screw comes out of the support that pushes the retainer that tightens the band/pad around the drum. Found that the pads were very worn down...

    Cat 955. Left side track, steering works some days, majority of the time steering does not turn

    Caterpillar 955. My left side track, the steering will work some days, and majority of the time will not work. Over the months, I’ll make slight adjustments, it will sometimes work for 30 mins, an hour and out of the blue work all day or until I turn off the machine. They nothing, the brake...

    955L Will Not Turn Over / Replacing Flywheel

    Status. Got it back in, but have not started it yet. Hopefully, it's just the batteries sitting around too long. My machine is 85j. One of the last machines in Caterpillar’s computer system. Anything older, you are at a lost in trying to figure out part’s numbers and finding parts. Starter...

    955L Will Not Turn Over / Replacing Flywheel

    Thank you. My guess is the 2 metal dowels come out. It's behind them are the threads, where to insert the screws. I'll try this next. Note, in the manual, the prior pictures are not showing these metal dowels which also can be confusing. "8. Install two forcing screws (10) in flange assembly...

    955L Will Not Turn Over / Replacing Flywheel

    So far, drained the diesel and hydraulic fuel, removed the shifting levels, pedals, hydraulic lines, torque convert flange, coupling drive, and the Flywheel Housing Cover. Now I'm stuck. Not able to get this Flywheel Plate Assembly off. I can't find a puller wide enough that is also narrow in...

    955L Will Not Turn Over / Replacing Flywheel

    I’ve removed the front 3 smaller belly guards to help get the starter out. The rear is a large plate and will start evaluating if there is enough room. Bummer part, just had the front apart, replaced the head gasket.
