    LT77 Gearbox Rubber Mount

    Could someone measure the diameter and depth of the rubber bit on an LT77 gearbox mount please?

    I think the threads are M8????

    No, I'm not "repairing" it, I'm fine tuning its performance.

    Craig,

    I can't answer your questions right now. I have a pair of CRC454 gearbox mount bushes somewhere in the back of the garage waiting for me to get around to fitting them. It's peeing down with rain here so I'll get your measurements later. In the meantime these are the items I bought from ANG..

    Thanks Russ, if if ever stops raining hopefully you could measure them for me, I think I've found an alternative at £11 for two, delivered.

    Craig,

    The rubber bush length is 37mm. Diameter 44mm. Length of the stud bar 69mm. The diameter of the stud is 7.5mm. It's not a metric thread.

    Bugger, I'm sure an M8 bolt fits my gearbox. The bushes I've ordered will be here tomorrow, i guess I'll find out then.

    Yep, all fitted today, £11 for two M8 rubber bushes, rather than £12 each if they're called "LT77 mounting rubbers"

    those mounts are not the same size as used on the LT77 and R380 box
    CRC454 is the part number and is 35 x 45.6
    where those mounts are 30 x 40
    i expect they would work but with rubber mounts there area many type of hardness and flexibility to the rubber
    i got a pair of CRC454 mount for £17 in the end that i know will work
    but worth a try
