    Mine has the clutch break return spring , close to that is a breather then there is a large filler plug . This is all under the air cleaner area .

    Komatsu 135A-1

    It looks like this is the only model with that part number , usually this parts catalog will show all the Komatsu's with the same part https://k-part.777parts.org/spare/komatsu/709-62-31201/

If there is smoke coming from the transmission it will be created by extreme heat . Best option is its the clutch break has dismounted and engaged...

    Adding hydraulic winch to a Komatsu D20S Track Loader

    Won't help me but other members may want a look . There will be issues matching flow and pressure for the winch that can be managed by a relief valve .

I'm sure it could have a remote cable to fix the dismounting problem . I'm...

    WW2 ARMOURED CATERPILLAR DOZERS (D7A)

    Bad mistake for Caterpillar to return to cable blades once hydraulics were developed costing operators fingers and worse what will be for over a hundred years of disfigurement , New model D7E's will be long buried before the last D7 3T will stop running .4T with her tin heads ready to roll ...

    Caterpillar D7 3T

    UPDATE on D7E Issues.

    That electrical junction probably has something to do with the conversion to direct electric start . Tilt for the blade is done with a ram fitted from the push arm to the top turnbuckle connection . Usually fitted to straight blades , like the one in the following photo . I have seen them on...

    UPDATE on D7E Issues.

    The one I had there was a pedal for my left boot to operate tilt . You may find there are all the valves needed to operate tilt under the panels disconnected . There is a cut slot in the panel shown in your picture that looks like the place
