After I replace my crankcase front seal, do I need to grease the outer shaft of the pulley that will be flush to the seal to prevent burning the seal?

And do you know the correct foot pounds for the balancer pulley bolt? Internet says 110flbs+60degrees.

Hi and thanks for using 2CarPros.

Any time you replace a seal, you must lubricate it with what it will be in contact with. In this case, motor oil. Anywhere the seal makes contact with a component which moves, place a thin coating of oil. Make sure to lubricate all of the seal's rubber parts. And yes, grease will work just fine for this.

As far as torque, here are the directions for removing and replacing the balancer. It includes torque specs and specific directions. Additionally, it does recommend the replacement of the crankshaft bolt.

CRANKSHAFT BALANCER REPLACEMENT
Crankshaft Balancer Replacement

Special Tools
* EN-470-B - Angular Torque Wrench
* EN-956-1 - Extension
* EN-49979 - Crankshaft Shock Mount Retainer

For equivalent regional tools, refer to Special Tools See: Engine > Electrical / Mechanical Repair > Special Tools.

Removal Procedure

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle See: Vehicle Lifting > Procedures > Lifting and Jacking the Vehicle.
2. Remove the right wheelhouse liner. Refer to Front Wheelhouse Liner Replacement.
3. Fix the drive belt tensioner, remove the drive belt from crankshaft balancer and lay aside. Refer to Drive Belt Replacement See: Drive Belt > Removal and Replacement > Drive Belt Replacement.

Note: The crankshaft balancer can be incorrectly installed 180° from the required position. Be sure to note the location of the alignment hole on the crankshaft balancer prior to removing the crankshaft balancer from the engine.

4. Rotate the engine clockwise until the bore (2) in the crankshaft balancer aligns with the mark (1) on the engine front cover.
5. Install EN-49979 - crankshaft shock mount retainer to EN-956-1 - extension.
6. Loosen the crankshaft balancer bolt (4) while fixing the crankshaft balancer (3) with EN-49979 - crankshaft
shock mount retainer (1) and EN-956-1 - extension (2).
7. Remove and DISCARD the crankshaft balancer bolt (2).
8. Remove the crankshaft balancer (1).

Installation Procedure
Note: The crankshaft balancer flange must fit to the hexagon of the oil pump rotor (2) and to the two-flat of the crankshaft (1). The TDC markings on crankshaft balancer and engine front cover must match.

1. Install the crankshaft balancer carefully by pressing into position.
2. Measure the distance (a) between the crankshaft balancer (2) and the mark on the engine front cover (1). The distance (a) should be 5.5 mm (0.21654 in).

Note: Never re-use the crankshaft balancer bolt.

3. Install a NEW crankshaft balancer bolt.
Caution: Refer to Fastener Caution See: Vehicle > Vehicle Damage Warnings > Fastener Caution.

Caution: Refer to Torque-to-Yield Fastener Caution See: Timing Components > Vehicle Damage Warnings > Torque-to-Yield Fastener Caution.

4. Tighten the crankshaft balancer bolt (4) to 150 Nm (111 lb ft) while fixing the crankshaft balancer (3) with EN-49979 - crankshaft shock
mount retainer (1) and EN-956-1 - extension (2). Use EN-470-B - wrench.
5. Tighten the crankshaft balancer bolt to an additional 60° while fixing the crankshaft balancer (3) with EN-49979 - crankshaft shock mount retainer (1) and EN-956-1 - extension (2).
6. Install the drive belt to the crankshaft balancer and remove the fixing pin. Refer to Drive Belt Replacement See: Drive Belt > Removal and Replacement > Drive Belt Replacement.
7. Install the right wheelhouse liner. Refer to Front Wheelhouse Liner Replacement.
8. Lower the vehicle.
9. Check and correct engine oil level.

Thank you very much Joe. Can you please clarify:

"5. Tighten the crankshaft balancer bolt to an additional 60 while fixing the crankshaft balancer (3) with EN-49979 - crankshaft shock mount retainer (1) and EN-956-1 - extension (2)."

Additional 60 foot pounds?

60 degrees. You will need a torque angle meter

Joe, I'm having an issue getting the pulley to go back on the crank shaft. I replaced the timing cover and now the pulley won't go on and advise would be amazing.

Hi,

Do you have the sheer key aligned with the pulley assembly? Do me a favor. Take a picture of the pulley center (where it would push on the crank) so I can tell if it is designed how I suspect it is.

Also, I attached the installation directions below.

Let me know.

Joe

See pics below. In the last pic, I included a general pic of the part and circled the keyway. Do you have that on your pulley assembly?

There are two flat spots on the pulley that need to align with the crankshaft. I circled them below. Let me know if that helps.

Yes, but the ring on the inside of the cover for the oil pump won't slide over the pulley to allow it to slide onto the crankshaft.

Hi,

I think I know what is happening. The engine must be at top-dead-center (cylinder 1). The mark on the pulley must align with the cover. See pics 1 and 2.

If they aren't aligned, the pulley won't go on.

Let me know if this helps.

Joe

See pics below.

Yes, I have it TDC. The oil pump ring isn't sliding onto the pulley to allow the pulley to slide onto the crankshaft.

Radford10, Joe helped me out too. It took a minute to get the balancer to line up with the ring and shaft. It did slide right in for me.

That ring seems to float. I aligned the ring first, the slid the balancer in a bit further then aligned the shaft. It’s a precision fit but should slide in as easy as it came out.
