The shafts on the parking brake cams of my Town Car show wear so I set about replacing the parts and installing lined shoes in place of the original cast iron shoes which have been there for the last 53 years I have had the T plus who knows how many miles in its first life.
Expecting to remove the old bushing for the brake cam I was surprised to find the Ruckstell diff backing plate has no bushing.
The backing plate has just been drilled 1/2' for the shaft. Is that how they all were or has this one just slipped through the system? Can't say I have ever heard anyone mention that there are no bushings.
Mine had no bushings and were worn, so I drilled them out and installed the stock Ford bushings.
The early Hall-Scott produced Ruckstells didn't have the bushing, while the later Eaton produced units had it according to earlier discussions at the forum:
Makes sense. Several parts of my Ruckstell were marked Hall-Scott.
My Ruckstell is an early Hall - Scott so that answers the question.
I've drilled it out and will add a bush tomorrow.
Rodger, you are amazing at finding old threads.
