Original Ford Specs translate to the newer 85/140 lube. The Muncie would be the same. The GL to use in the TT differential should take into consideration the brass components inside though.

I'm not a fan of the of the modern gear lube/bronze parts debate myself. Most all of the older synchromesh transmissions and two speed truck rear ends used in the '50's-'60's (and many other gear sets) used bronze parts. They all used (mostly) plain old 90 weight gear lube. Never any problem with the lube causing problems with the bronze parts. I'm by no means an expert, just my observations over the last 50 years.

Bob,

I'm using Chevron Gear Compound EP ISO 680 in my '26 TT rear axle with 9000 miles since a total rebuild. The Chevron Gear Compound has a AGMA Grade of 8 EP, is ISO 680 Grade, an API gravity of 26.0, a viscosity index of 100, Timken OK load in lbs. @ 65, meets AGMA 9005 (ISO 680), rust & corrosion inhibited -- reduces corrosion on either steel or non-ferrous metals in gear sets.

The Chevron Gear Compound is also used in my Twin Hi Lo auxiliary transmission (under, direct, & overdrive) in my TT.

Jack

Thanks guys I want use same in Muncie and rear
I'm thinking any lube today must be better
I bought some 85/140
Steel and bronze make a great bearing combo
I load it up and give this a go
Couple tractor guys recommend it as well and they not had trouble with it and bronze parts
I could not find the chevron product
