Remove

TOC

Remove the camshaft bushings. Use the camshaft bushing replacer kit, Part Number 3165045.

The following kits are also available for camshaft bushing installation and removal:

  • Hydraulic Actuator Kit, Part Number 3823621
  • Camshaft Bushing Kit, Part Number 3162253

Slide the drive bar through the centering guide and insert the drive bar from the rear of the cylinder block through the camshaft bores.

Insert the camshaft bushing replacer and drive the front camshaft bushing from the cylinder block.

Remove the replacer and drive bar from the cylinder block.

Insert the drive bar, camshaft bushing replacer, and centering guide from the front of the cylinder block.

Drive the remaining camshaft bushings from the cylinder block in succession, starting with the number two camshaft bushing.

Remove the drive bar, replacer, and guide from the front of the cylinder block.

Install

TOC

Mark the oil holes on the camshaft bushing and cylinder block with a felt tip pen. This aids proper alignment of the bushing and bore during installation.

NOTE: The top hole on the front and rear camshaft bushings will not line up with the top hole of the cylinder block bores. Only the bottom hole will line up for the front and rear camshaft bushings.

Slide the camshaft bushing on the replacer. Position the notch on the edge of the bushing to the top rear of the block and align the marks on the camshaft bushing and the cylinder block.

Drive the front camshaft bushing to the correct installed depth. The correct installed depth is when the camshaft bushing oil hole aligns with the cylinder block oil hole.

Install the remaining camshaft bushings in succession, starting at the rear of the cylinder block and working toward the front. Remove the drive bar, replacer, and guide from the cylinder block.

Remove the drive bar, replacer, and guide from the cylinder block.

Make sure the lubricating oil holes in the camshaft bushing are aligned with the oil holes in the camshaft bore. For the front and rear camshaft bushings only the bottom hole will line up with the hole in the cylinder block.

A 3.2 mm [0.128 in] diameter rod must be able to pass through the lubricating oil holes.
