To Moly or not to Moly?

[edhackett]

I've begun the restoration of my 1941 John Deere B. I'm looking at this grease for all of the bearings and bushings. The service manual just says high temperature grease. All of the bearings that get greased are tapered roller, low speed (

This is another option that I already have on hand, chosen specifically for a low speed, plain bearing application. I'm not sure the 460 viscosity base oil is ideal for the roller bearings.

What say you all?

I would use the grease you already have on hand. This is a very good grease that I have seen used by many in the farming and dairy community around here.

After the restoration please post some pics. Great old tractors.

From what I've read moly isn't very beneficial in roller/ball/needle bearings.

For general lubrication I happen to think the Delo Grease EP with a GC-LB rating is one of the better ones. The greases you linked to are not GC-LB rated. If you are using old parts then a moly additive might be worthwhile. If new bushings or bearings, then you might consider a GC-LB rated grease. I suspect any modern day grease to far exceed the expectation of the originial design. Delo Grease EP

If you are looking at a restored tractor then I could assume that it would not operated much. Could be a tractor for show? In that case a grease with moly may not be needed but could be a help in some way. Chevron Delo would be a good bet. With a high viscosity it would create a good dust barrier for storage and corrosion protection. It is one one the top commercial greases out there and easy to find.

Moly grease wasn't available in the corner store when that truck was built.
I believe it is a very good general purpose grease.
