    Reverse engineering Cat Telehandler Shift rail controller

    My father has a cat 330b which does not always like to engage its gearbox. Many hours sitting waiting for the damn thing to start working. This seems to be a common failure on these cat machines. I got me wondering if it is possible to controller the gearbox externally using a arduino or...

    Caterpillar TH330b self repair mission

    Problem 2 with the gear box has unfortunately not resolved. It seemed to work better after calibration but this may have just been a good run of luck for a few days. Now I am thinking about replacing the forklifts brain (ecu?) Is there anyway of re flashing the unit myself or can I buy a...

    Caterpillar TH330b self repair mission

    Fitted the solenoid valve a couple of days ago and I'm happy to say it has fixed problem 1. I will continue to monitor problem 2 and hopefully it does not come back. Thanks again for everyone's help.

    Caterpillar TH330b self repair mission

    Nige, many thanks for sending me the electrical schematic. Using Cmarks 10.5 ohm benchmark I tested the solenoid and could not get much resistance in the coil.

    Caterpillar TH330b self repair mission

    Hello, I have a 2005 Cat TH330b forklift and it has been a great machine up until now. Recently it has started giving us some problems, I shall try my best to describe them and hopefully someone may be able to shed some light on my issues. There are two main problems. One is intermittent and...

    Caterpillar Transmission

    Hi, I have a very similar problem with my CAT TH330b. Originally the forklift would sometimes not find forth gear and the machine would default to neutral. Now 50% of the time, when I go to use the forklift the shuttle will not work at all in any gear. The rear reversing beeper does come on...
