Replacing the Crankshaft Balancer and Balance Weights
WARNING: This page is about a different variant/trim than selected.
- Check the crankshaft balancer weight holes for any existing balance weights.
- Use a punch and position the balance weights to the bottom of the weight holes.
- With a marking crayon, note the weight holes containing balance weights.
- Lay the old crankshaft balancer on a bench or flat table.
Rotate the old balancer until one of the marked balance weight holes is in the 12 o'clock position.
- Lay the new crankshaft balancer on the bench next to the old balancer.
Rotate the new balancer until one of the balance weight holes is in the 12 o'clock position.
- With a marking crayon, mark the new balancer weight hole located in the 12 o'clock position.
- Viewing the old balancer, note the position of the crankshaft-to-balancer alignment mark.
Mark the new balancer in the same location.
- Measure the distance from the top of the balance weights to the face of the old crankshaft balancer.
- Record the readings.
- Determine the proper balance weight size for the new balancer.
- A balance weight hole depth that measures 13.0 mm (0.512 in), has a short balance weight in the hole.
- A balance weight hole depth that measures 6.69 mm (0.263 in), has a medium balance weight in the hole.
- A balance weight hole that depth measures 0.29 mm (0.011 in), has a long balance weight in the hole.
- A short balance weight will measure 12.7 mm (0.5 in) in length.
- A medium balance weight will measure 19.0 mm (0.75 in) in length.
- A long balance weight will measure 25.4 mm (1.0 in) in length.
- Insert new crankshaft balance weights of the proper size into the new balancer in the same location as with the old balancer.
A properly installed balance weight will be either flush or below flush with the face of the balancer.
IMPORTANT:
The position of the crankshaft balancer must be marked before removal, relative to the crankshaft. The balancer does not use a key or keyway for positioning. Mark or scribe the end of the crankshaft and the balancer before removal. The crankshaft balancer must be installed to the original position. If replacing the crankshaft balancer, note the location of any existing balance weights, if applicable. Crankshaft balancer weights must be installed into the new balancer in the same location as the old balancer. A properly installed balance weight will be either flush or below flush with the face of the balancer.
