SUBJECT: Mast Hangers and Hanger Bushings
Vista 2Stg., 3Stg., and FL.
There are two new options available for servicing mast hanger bushings on the S/E 70-120XL series trucks.
Both options incorporate phenolic bushings to replace the original steel backed bronze bushings. The bushings
are retained in the hangers by means of pins or plugs.
Drive axle housing journals should be in good condition or returned to their proper specifications of 5.311"-
5.315" diameter with a 125 micro-inch finish before servicing with new bushings.
For service use only the original steel backed bronze faced bushing P/N 373226 has been reinstated under a
new number P/N 1376399.
OPTION I REPLACEMENT BUSHING KIT (P/N 1380118)
This kit contains replacement phenolic mast hanger bushings, which can be used to service the original bushing
P/N 373226. A modification to the hanger cap is required for this bushing and is depicted below.
(Bushing can be used as a drill guide location.)
We reserve the right to make changes in design or add improvements without incurring the obligation to make such changes in
equipment previously manufactured.
