I have a 48"bobcat ransomes xm4810 with the worm gear drive transmission (not the peerless) and I recently noticed after using it, the transmission feels hot to the touch. Like if you held your hand there you would get burned. I am using it with a sulky but I'm not that heavy (like 120 lbs) so that could be part of the issue? After noticing this, I changed the 20% Lucas oil heavy duty stabilizer and 80% gl5 80w 90 gear oil I was running in it to straight gear oil and this didn't solve the issue. I contacted Lucas about using more Lucas oil stabilizer to help cool the gearbox and they said that I shouldn't use more than 5% in the worm gear drive. My question is, are these gearboxes supposed to run hot or or is mine on its way out? Thanks!
