Butch 194 #1 Posted August 23, 2013 Straight SAE140 is very hard to find. Lucas makes it and you can buy it at Jeggs. Not cheap. SAE85W140 is made by everyone. My WH manual says to use SAE140 straight. Any of you using the multi-grade gear lube? What would the multi-grade hurt by using it. It must be heat related. Is it possible that when the tractor was made they didn't have multigrade gear lubes hence the straight SAE140. Share this post Link to post Share on other sites
rmaynard 15,602 #2 Posted August 23, 2013 85/140 is what the lubrication manual calls for, but I don't see why 140 wouldn't work well in summer weather. Might be a little stiff in winter. 1 Share this post Link to post Share on other sites
Butch 194 #3 Posted August 23, 2013 Thanks Bob. Yeah my Blackhood manual shows it straight. I never did look at my lube manual. So I'll now use the 85/140. Thanks again. 1 Share this post Link to post Share on other sites
Tom J 1 #4 Posted April 15, 2014 I have the same question, for my '73 14-8 tractor. Has the 85-140W gear oil been ok to substitute for straight SAE 140 as the manual asks for? No plowing for me, just grass and trailer pulling. Tom Boston Share this post Link to post Share on other sites
rmaynard 15,602 #5 Posted April 15, 2014 The lubrication chart calls for 90/140 for your 14-8. I would just go to Walmart and get a gallon jug of 85/140 for $12.76. 1 Share this post Link to post Share on other sites
Stubby 19 #6 Posted December 12, 2020 I have replaced mine on my c101 and c105 with 85-140 but after I run it it looks kind of milky. Normally that would be water issue. But this is the second time and I am going to change it one more time. Not sure if that is normal, which I am thinking it is not. Share this post Link to post Share on other sites
slim67 2,735 #7 Posted December 12, 2020 I got this out of an elderly neighbors trash. He passed away and his wife has been getting rid of stuff. The pump works and it’s still half full. I will use it for my 654. Share this post Link to post Share on other sites

ATF ... it's possible you did this - but some milky oil residue still remained Edited December 12, 2020 by tom2p Share this post Link to post Share on other sites
Stubby 19 #9 Posted December 12, 2020 I just finished it, flushed it twice with diesel and added new. Not milky anymore. Garage kept machines one with plow and one with snowblower. Ready to go now. Thanks 2 1 Share this post Link to post Share on other sites
stevasaurus 22,863 #10 Posted December 13, 2020 I think Diesel is the best for flushing. I would not use ATF, no matter what, you would have a red residue that may not agree with your new 90wt oil. Share this post Link to post Share on other sites

(inherited a number ATF quarts from family member) ATF has great lubricating properties and detergents - so I gave it a try worked well - though I did flush again with gear lube before final fill I don't believe there should be any bad effects on brass or bronze or copper ... ? ... or whatever materials are lurking inside the Wheel Horse 8 speed trans ...
