My Hurth gearbox
HBW20 has developed a significant oil
It APPEARS to be exiting through the gear
change shaft seal
on the side. One mechanic
stated this required removal
and a COMPLETE strip down in order to replace the seal, though not sure he actually wanted the work, so not sure.
Any views on this? If its true, then I'm guessing it would be far simpler just to look for a replacement unit.
I'm using Dextron/ATF. Wondering if that's ok on such an elderly unit, though don't know what else I'd use?
Any advice appreciated please
