Hi, following a fluid change on my LT77 gear box I have developed a leak on the drain plug. I can’t remember if there was a copper washer there but on the parts diagram its doesn’t show any. Is this correct ???


When I looked up parts for the LT77 I see on eBay that people sell a kit with a copper washer ( FTC 4112 ). If correct does the copper washer go between the fabric washer and the drain plug or between the fabric washer and the gear box face?

One or the other, not both

As per @freelance . I prefer copper washers and a wrap of gas PTFE around the thread.

You don’t use both. I use the copper washer and re-anneal it each time but you can use whatever you fancy - copper or fibre - they both do the same job

Thanks all, maybe i need to check the torque setting on the drain plug to stop the leak... the books noted 51 Nm. Seem high..!!!
