[TR] TR4A to TR6 Windshield Wiper Conversion

[Greg Lemon]

I was considering this for my TR250 as well, I have been fighting weak wipers since I got the car back on the road.  I have a used TR6 motor that works fine, and started looking at the conversion, but it kept getting more complicated (motor mount seems totally different, as does the wiring),  can't find the info on the TRF site, any more details would help,  thanks, Greg

Subject: [TR] TR4A to TR6 Windshield Wiper Conversion


After many many years of crappy windshield wiper operation I decided to take the plunge and convert the wiper motor on my TR4A from the Lucas to the Smiths version. Wow, what a difference in the strength of the motors. Before doing this I changed out motors, replaced wheelboxes, replaced tubing, and replaced wiper arms trying to keep as original as possible. Some of these things improved performance but nothing anywhere close to doing the TR6 swap. Thanks to Charles at TRF who inspired me with a short blurb on one of his catalogs about doing the same thing on his TR5. 

 

The main parts you'll need is the wiper motor (on sale at TRF), late TR6 wiper switch, TR6 wheelboxes, 5/16" tubing, and an electric washer pump. The vacuum/push pump on the dash gets replaced with a modern electric one. Very slick install. Unless you really know what to look for it looks like the factory put it in.

 

I don't have time to write up the conversion now as my Grandson and I are about to load up the TR4A and head out for a week of fishing in the Eastern Sierra's. I'm hearing the trout are biting! Hope the bears aren't!
