It is not a happy day when ones gearbox starts to grind.
Being the offspring of pioneers where repairs to broken wagons were done with whatever materials lying around, we tend to follow that creed. For example, with the rear mainshaft bearing next to the drive shaft flange, we used a sealed ball bearing to better hold in the gearbox oil. We considered placing magnet against the case wall to help trap swarf. We pondered the possibilty of a sort of filter or screen over the oil pump pickup to keep the swarf out of the oil pump. We changed fifth gear to the later one from a fuel injected model to reduce engine speed at highway velocities. And, we thought about a gearbox substitution.
Then we looked at costs. Sure, anything is possible but is it worth it in terms of time spent, performance/fuel economy, and money. In the end, we decided to go with an overhaul and make certain modifications in keeping with our skills and funds available. We're glad we did. However that's just us, it may not be you. The R380 is reputed to be a fine evolution of the LT77. Are they available in your part of the world? They weren't in ours.
We wish you good luck with your upcoming project, please observe good safety practices.
