RAM 2500 Truck 2WD L6-5.9L DSL Turbo VIN 6 (1998)
Thrust Plate Bolt Location
7. Remove the bolts from the thrust plate.
8. Remove the camshaft, gear and thrust plate.
BUSHING REPLACEMENT
1. Measure the diameter of each bore. (The limit for the bushing in the No.1 bore is the same as for the other bores without bushings). The limit of
the inside diameter is 54.133 mm (2.1312 inch). If the camshaft bore for the first cam bushing is worn beyond the limit, install a new service
bushing. Inspect the rest of the camshaft bores for damage or excessive wear.
2. If the bores without a bushing are worn beyond the limit, the engine must be removed for machining and installation of service bushings. If badly
worn, replace the cylinder block.
3. Remove the bushing from the No.1 bore, using a universal cam bushing tool.
4. Mark the cylinder block so you can align the oil hole in the cylinder block with the oil hole in the bushing.
Apply a coating of Loctite 609 to the backside of the new bushing. Avoid getting Loctite in the oil hole.
Oil Hole Alignment
5. Use a universal cam bushing installation tool and install the bushing so that it is even with the front face of the cylinder block. The oil hole must be
aligned. A 3.2 mm (0.128 inch) diameter rod must be able to pass through the hole.
6. Measure the installed bushing. The limit of the inside diameter is 54.133 mm (2.1312 inch).
GEAR REPLACEMENT
1. Press the camshaft out of the gear.
2. Remove all burrs and smooth any rough surfaces caused by removing the gear.
3. Install the camshaft key.
4. Lubricate the camshaft surface with Lubriplate 105, or equivalent.
CAUTION: The camshaft gear will be permanently distorted if overheated. The oven temperature should never exceed 177°C (350°F).
5. Heat the gear in an oven at 177°C (350°F) for 45 minutes.
WARNING: Wear protective gloves to handle the hot gear.
6. Install the gear with the timing marks visible. Be sure the gear is seated against the camshaft shoulder.
7. If the camshaft is not to be used immediately, lubricate the lobes and journals to prevent rust.
INSTALLATION
1. Apply a coat of Lubriplate 105 to the camshaft bores.
2. Lubricate the camshaft lobes, journals and thrust washer with Lubriplate 105, or equivalent.
