• | J 45027 Tensioner Tool

1. Ensure that the primary camshaft drive chain tensioner (3) is being installed.
2. Using the J 45027 , reset the primary camshaft drive chain tensioner plunger.
3. Install the plunger into the primary camshaft drive chain tensioner body.
4. Compress the plunger into the body and lock the primary camshaft drive chain tensioner by inserting the EN 46112 into the access hole in the side of the primary camshaft drive chain tensioner body.
5. Slowly release pressure on the primary camshaft drive chain tensioner. The primary camshaft drive chain tensioner should remain compressed.
6. Install a NEW primary camshaft drive chain tensioner gasket to the primary camshaft drive chain tensioner.
7. Install the primary camshaft drive chain tensioner bolts through the primary camshaft drive chain tensioner and gasket.
8. Ensure the primary camshaft drive chain tensioner mounting surface on the engine block does not have any burrs or defects that would degrade the sealing of the NEW primary camshaft drive chain tensioner gasket.
9. Place the primary camshaft drive chain tensioner into position and loosely install the bolts to the block.

Notice: Refer to Fastener Notice in the Preface section.

10. Verify the proper placement of the primary camshaft drive chain tensioner gasket tab (1).

Tighten

1. First Pass

Tighten the primary camshaft drive chain tensioner bolts to 5 N·m (44 lb in).

2. Final Pass

Tighten the primary camshaft drive chain tensioner bolts to 23 N·m (17 lb ft).

11. Release the primary camshaft drive chain tensioner by pulling out the EN 46112 and unlocking the tensioner plunger.
12. Verify the primary and left secondary camshaft drive chain timing mark alignments (1-12). Also refer to Camshaft Timing Drive Chain Alignment Diagram - Stage One.
13. Remove the EN 46105-1 from the rear of the left camshafts.
14. Using the EN 46111 , rotate the crankshaft and crankshaft sprocket from the stage 1 alignment position (1) to the stage 2 alignment position (2), 115 crankshaft degrees, in order to install the right secondary camshaft drive chain components.
15. Install the EN 46105-2 onto the rear of the left camshafts.
16. Install the EN 46105-1 onto the rear of the right camshafts.
