Installation instructions

The direct oil feed (DOF) solution uses a patent pending custom made Intermediate Shaft Flange that utilizes a direct oil feed to the original Intermediate Shaft Bearing. It uses an adapted pressure fed oil line from a positive oil pressure feed on the cylinder head directly to an opening in the custom Intermediate Shaft Flange. This feeds fresh oil directly to the open end of the IMS bearing (after removing the seal to expose the ball bearings on the IMS bearing). By using a positive oil feed from the engine's cylinder head valve cover, there will always be a consistent flow of oil directed to the open end of the intermediate shaft bearing.

This is a cost effective way to help protect against a possible IMS bearing failure, using the original bearing. The system, however can also be used when replacing the bearing with a new SKF steel ball bearing for added insurance with a new, zero mile bearing.
