If excessive camshaft wear is found, or if the engine is completely rebuilt,
the camshaft bearings should be replaced. Use these service repair procedures
as a guide.

- Remove the head and place it on a work stand.
- Remove the camshaft.
- Using a tool such as Bearing Replacer T71P–6250–A, remove the
bearings.
- Coat the new bearings with clean 50W engine oil and install them with the
tool.
- Remove the engine and place it on a work stand.
- Remove the flywheel.
- Remove the camshaft.
- Using a sharp punch and hammer, drive a hole in the rear bearing bore plug
and pry it out.
- Using the special tools and instructions in Cam Bearing Replacer Kit T65L–6250–A,
or their equivalents, remove the bearings.
- To remove the front bearing, install the tool from the rear of the block.
To install:
- Following the instructions in the tool kit, install the bearings. Make sure
that you follow the instructions carefully. Failure to use the correct expanding
collets can cause severe bearing damage!
NOTE: Make sure that the oil holes in the bearings and
block are aligned! Make sure that the front bearing is installed 0.51–0.89mm
below the face of the block.
- Install a new bearing bore plug coated with sealer.
- Install the camshaft.
- Install the flywheel.
- Install the engine.
On both of the MPV engines (2.6L and 3.0L), excessive oil clearance between
the cylinder head/bearing caps-to-camshaft bearing surfaces, indicates that
cylinder head and/or camshaft replacement is required.
