B5.9G, B5.9LPG – Troubleshooting and Repair Manual – 001-010   Camshaft Bushings

Inspect the camshaft bore for damage and excessive wear.

Measure the camshaft bore.

NOTE: Camshaft bores No. 2 through 7 do not use a bushing.

NOTE: The introduction of the storm block increased the camshaft bushing bore diameter by 2 mm [0.079 in] to accept a larger outer diameter cam bushing. The camshaft inner diameter did not change.

NOTE: If the bores without a bushing are worn beyond the limit, the engine must be removed for replacement of the cylinder block.

Camshaft Bushing Tool, Part No. 3823509

Remove the camshaft bushing from the No. 1 bore.

Mark the camshaft bushing and cylinder block so you can align the lubricating oil hole in the cylinder block with the lubricating oil hole in the bushing.

NOTE: Make sure the bore in the cylinder block and the outside diameter of the bushing are clean from oil and dirt.

Measure the installed camshaft bushing.

Apply Loctite primer to the outside diameter of the bushing and the inside of the camshaft bore of the cylinder block.

Allow the primer to dry.

Apply a bead of Loctite 609, or equivalent, to 270 degrees along the edge of the bushing that will be installed toward the rear of the cylinder block.

CAUTION  Make sure there is no Loctite in the oil hole, or severe engine damage can result.

Use extreme care not to apply Loctite to the oil hole in the bushing.

Camshaft Bushing Tool, Part No. 3823509

Install the camshaft bushing so that it is even with the front face of the cylinder block.

Use a clean, lint-free cloth to wipe off any excess Loctite.

CAUTION  Make sure there is no Loctite in the oil hole, or severe engine damage can result.

Be sure the lubricating oil hole is aligned.

A 3.2-mm [0.126- in] diameter rod must be able to pass through the lubricating oil hole.

Complete the installation of the removed parts.
