Illustration 1. Location of 1U8846 or 4C5300 Flexible Gasket Maker (1).
The sealant is available for part service as 1U8846 (1.5 oz tube) or 4C5300 (10.5 oz tube Flexible Gasket Maker. The sealant directly replaces the 7E2633 Gasket in the oil pan groups shown in the chart. This is the same sealant used between the rear housing and block on the 3500 Engines in Caterpillar Off-Highway Trucks. This change is adaptable to first production.
