1995 Dodge Ram 3500 V-10

This weekly Q&A session answers your questions about cars and trucks. This week explores a 1995 Dodge Ram 3500 that needs a new crankshaft pulley.

Question: 1995 Dodge Ram 3500 V-10

I need to change the harmonic balancer and can't figure out how to get the clutch fan off. I need advice or a manual download. Also, any advice on changing the harmonic balancer would be greatly appreciated. I'm on the side of the road and have just had enough for part. What else might I need? I have a puller.

Answer:

The fan/fan drive assembly is taken off the water pump by rotating the mounting nut counterclockwise (as viewed from front). So you will need to get a wrench and hold the water pump so it doesn't turn while you remove the mounting nut.

There is nothing special about removing the harmonic balancer/flywheel pulley. All you need to do is remove the front crankshaft bolt, remove the harmonic balancer/flywheel pulley and replace it with a new one.

There is a Technical Service Bulletin out on the harmonic balancer/flywheel pulley, however:

• No: 09-04-98
• Group: Engine
• Date: Sep. 25, 1998
• Subject: Accessory Drive Belt Noise Or Damage/Crank Pulley Bolt Loose.
• Models: 1994 - 1999 (BR/BE) Ram Truck

Note: This information applies to vehicles equipped with an 8.0 liter V-10 engine.

Symptom/Condition

Some vehicles may exhibit a condition where the accessory drive belt becomes damaged on the inboard edge. Customers may explain the problem as belt noise. This may be caused by the crank pulley loosening on the crank and causing a misalignment.

Diagnosis

Inspect the accessory drive belt for fraying or unusual wear on the inboard edge. If wear is noted, inspect the crank pulley bolt for looseness and the crank pulley for misalignment. Sight the crankshaft pulley with other accessory drives or use a straight edge to detect misalignment. If the crank pulley is misaligned or bolt is loose, perform the Repair Procedure.

Repair Procedure

This bulletin involves removing the crank pulley bolt, checking the press fit of the pulley, reinstalling the bolt using thread locker, and replacing the accessory drive belt.

1. Disconnect the negative battery cable.
2. Remove the accessory drive belt following service manual procedures.
3. Drain and remove the radiator following all service manual warnings/cautions and procedures.

Note: Drain the coolant into a clean drain pan.

1. Remove the bolt attaching the crankshaft pulley damper to the crankshaft.
2. Using your hands, pull on the crankshaft pulley damper to test the press fit to the crankshaft. The pulley should be tight and not come off the crank with hand pressure.

Note: If the crank pulley damper is loose (no press fit) replace the crank pulley damper with P/N 53020776.

1. Use Miller Tool C-3688 and fully press the crankshaft pulley damper onto the crankshaft.
2. Add thread locker P/N 04318032 to the end 3 or 4 threads of the crank pulley bolt.
3. Install the bolt and torque it to foot-pounds.

Note: Use a bar to lock the pulley in place while tightening.

1. Install the new accessory drive belt following service manual procedures.
2. Reinstall the radiator following the service manual procedures.
3. Reinstall the negative battery cable.
4. Fill the cooling system with the saved coolant and operate the vehicle to purge air from the system. Top off the automatic transmission fluid (if required).

And that should do it for you.

That's all for this week. Feel free to browse the archives for past topics and other resources. And, as always, if you are stuck and need an immediate answer you can always call Vince on the phone.
