evan4434 0 #1 Posted March 17, 2010 Like the tile says what gear oil do I use for a 416-8. I believe this would be the Eaton model and it is not a hydro. Thanks Share this post Link to post Share on other sites
Sparky-(Admin) 21,405 #2 Posted March 17, 2010 All the hydros of that era are either Eaton 1100 or 700's. What you have is an 8 speed "Uni-Drive". It takes 80-90 weight gear oil. Mike........ Share this post Link to post Share on other sites
WH854 44 #3 Posted March 17, 2010 I could be mistaken but a 416-8 is an 8 speed manual transmission I think it is not an Eaton Model. It was Made By Wheel Horse. I put 85x90x140 gear lube, holds two Quarts. Chas Share this post Link to post Share on other sites
