Inspection of Your Balancer

So, after 40 or 50 years, your balancer has bit the dust?  We
present the following as a guide to those unsure if their pet
project needs a balancer rebuild.

If your engine has been running and the timing can be set
reliably, that's a sign your balancer is still in good condition.

Some balancers have minor cosmetic needs, but are in very
good condition and do not need rebuilding.  A cosmetic
condition that often occurs is the extrusion of the original rubber,
forming a bulge or ridge on the balancer.  This can be easily
trimmed without affecting the balancer or rubber adhesion.

If the rubber surface appears to be shiny and resilient when
gently poked, this indicates a good overall condition.

Another self-test is the shaft seal surface.  Sometimes the shaft
seal will wear into the hub surface, causing a groove to form.  
This could result in constant oil leakage if not corrected.  Check
by looking for a worn area, or ring, where the seal rides.  Run
your fingernail over and along the ring.  If a ridge can be felt, it's
time for a shaft repair sleeve.

We hope the above will provide useful info to our potential
customers.  Thank you and Good Luck with your pet project!
