grinchsr 657 #1 Posted 11 hours ago Am I understanding correctly that my 36" tiller ( 07-36TL04) only takes one quart of gear oil? It seems like it should require more. Share this post Link to post Share on other sites
ri702bill 11,615 #2 Posted 10 hours ago That makes sense. It is a rather small, compact gearbox unlike a Unidrive. You never completely fill an enclosed cavity full of oil - as it heats up, it builds internal pressure. If it is not vented, it can send a lot of oil out under the seals... 1 1 Share this post Link to post Share on other sites
lynnmor 8,697 #3 Posted 7 hours ago There is a large drive chain inside that will drag the oil to the top of the case. 1 Share this post Link to post Share on other sites
Skwerl58 812 #4 Posted 2 hours ago I just took mine apart and reassembled it. I added 28 ounces of 85 140 and it is super quiet and no leaks. 1 Share this post Link to post Share on other sites
