PhanDad Posted February 17, 2019 Posted February 17, 2019 Just noticed the statement "Don not brush grease on tooth surfaces of gear or pinion" at the bottom left of this IPL for a 7100 series tractor: The 7000 series tractors have the same note on a separate page of notes of the basically same IPL. Greasing these items seems to be the "normal"; most tractors I've acquired have grease. I've always greased them. I know the grease will pick up debris and require cleaning occasionally and if not greased, this probably wouldn't happen. Are they supposed to run dry? What am I missing? 1
kwt Posted February 17, 2019 Posted February 17, 2019 I regularly operate a couple of machines with large open spur gears under load, sometimes major. The manuals say to keep them clean and greased. I've never actually cleaned them, but grease goes on pretty often. They do not run in a dusty environment. Most cement mixer manuals will tell you to grease the open circular rack and pinion, but almost nobody does. I grease my Simp gears and actually own an oil can that is used regularly. I imagine that Simplicity decided that they didn't want dirt to stick to the gears. The gear and sector are IMO very large for the job they are doing so maybe they figure that the PSI on the gears does not justify lubrication. 1
kwt Posted February 17, 2019 Posted February 17, 2019 (edited) I see that the older smaller gears do call for lubrication every 25 hrs. according to a 1973 Homelite T16H owners manual. The gears on this Homelite are similar to a 3112v and an Allis B-210. Edited February 21, 2019 by kwt added B-210 1
Brettw Posted February 17, 2019 Posted February 17, 2019 Only thing I could figure would be the dust/dirt factor. Beyond that I can't see why grease would hurt anything. 1
MrSteele Posted February 20, 2019 Posted February 20, 2019 I am building a Landlord right now, finally putting it back together. I considered a dust cover for the gears, but not really sure it is necessary. I squirt a shot of oil on the gears every now and then when I think about it. Have to remove a side cover to do it, so was thinking a good grease and a dust cover. I put a new bushing in the steering gear with as liberal a dose of White Lithium grease as would stay after assembly.

I collect oil cans for the heck of it, have them ranging from about the size of a thimble to several old pump cans with brass pumps and steel check balls. The range makes it easy to get oil anywhere I want to put it 2
jlasater Posted May 13, 2019 Posted May 13, 2019 Would a good quality dry lube work well here? I have a can of industrial high-solids dry lube available.
