stevebo-(Moderator) 8,351 #3 Posted November 20, 2013 I used 80/90 in mine. If you saw what came out of it pretty much ANYTHING would have been better-lol. I also changed the gearbox and steering box oils as well. Share this post Link to post Share on other sites
shorts 182 #4 Posted November 20, 2013 I would imagine that old fashion 80/90W gear lube was factory fill, the multi-weight and synthetic products didn't exist back then, also would be concerned about seal compatability with the modern lubrication chemical composition. 1 Share this post Link to post Share on other sites
HorseFixer 2,012 #5 Posted November 29, 2013 Thanks Guy's I plan on replacing all Gaskets and Seals & Bearings where needed. Yes and I will switch over to Synthetics With Compatible Types. Share this post Link to post Share on other sites
