Post Trip Report

The trip to Gettysburg was just a little over 1000 miles round trip and everyone enjoyed the event hosted by the Hub City Model A Club.  Job well done.

The Model A's that made the trip all arrived home with out any problems on the last day on the road.

I finally was able to get our Model A up off the ground and took out the rearend. We did some testing to make sure the problem was isolated to the Overdrive; all the test pointed to that as the source of the problem.

As you can see in the picture the Borg Warner OD is out and resting on the transmission jack.  I have had this overdrive unit in the Model A since 1991, so I can't complain about its reliability. I have had to service it a couple of times, but the unit always gave me good service.

In anticipation of this unit getting old and harder to find NOS parts, I had purchased a Volvo overdrive setup from Rich Little in California.  This unit is very well designed and parts, if needed, are readily available.

Yesterday a few friends helped me install the new overdrive.  Thankfully, Jack had the special tools that made the pinion gear removal and installation so easy.  The installation of the overdrive is very straight forward.  The one area that is a little stressful is the installation of the reverse lockout switch on the transmission tower.  This was done carefully and all the electrical connections checked out A-OK.

This final step was the test drive, and the new unit performed perfectly.  It's great to be back on the road again.

I will inspect the Borg Warner OD to see what the cause of the problem was and report my findings.
in the meantime ....Happy Model A'ing
