501 AlliCat Heavy Duty Transmission Lubricant

C-4/TO-4

Specify Grade 10, 30, 50, or 60 


Description: AlliCat 501 meets and exceeds the Caterpillar TO-4 Specification for transmission and drive train fluid requirements.  Caterpillar states the need  for TO-4 specification lubricants in current equipment for increased productivity and durability, higher bearing and gear loads, and new diverse friction materials.  AlliCat 501 is a specialized fluid type that must replace all motor oils and torque fluids previously used in Caterpillar transmissions to maintain warranty protection.

AlliCat 501 also exceeds Allison C-4 transmission requirements. Allison Transmission no longer approves the use of tractor hydraulic fluids which were previously approved under the Allison C-4 specifications.  AlliCat 501 should replace these fluids in all Allison transmissions.
Composition: Primrose utilizes the only basestocks select enough to be qualified by Caterpillar and Allison.  To these are added a uniquely balanced combination of additives which far exceed these heavy duty performance criteria.
