Article 16 - Lubricant Leaks at Spindle Pin Cap and Gasket

TSB #1 - September 15, 1971
(1972 and Prior - All Heavy and Extra Heavy Trucks with 9,000 and 12,000 Pound Capacity Front Axles except Center Point)


A new spindle pin cap with increased metal thickness and a gasket with revised material specifications will improve lubricant leaks at the gasket when high pressure lubrication equipment is used.

The new cap and gasket may be installed on prior model vehicles when lubricant leaks are encountered. (The service kit for this correction includes the new parts.)
