OK, all you guys with a BHJ or TA steel balancer, I am going to give you an early "Christmas present" and give away a secret for a very easy method we have used for years to install these units that MUST have a press fit on the crank to do their job properly! I used to fight with the problematic balancer installation tool before we found this much better way.
The first thing to do is use piece of emory cloth on the bore of the balancer to remove any burrs or sharp edges.
Then use a hand-held propane torch and heat around the end of the shaft of the balancer for just a few minutes, and it will just slide in place.
Only other "tool" needed is a pair of gloves to finish the job sliding it on the crank.
After working on a few thousand TR's over 25 years, I have learned a few things not in the shop manual or on instruction sheets!
