Have any of you experimented to see if a lighter grease improves the wipers' speed and power?
I've tried even using gear oil on my TR3A; didn't make any difference that I could see. What did make a difference was :
1) Making sure the wiper motor was getting full battery voltage ... the ground at the switch was poor.
2) Making sure the rack moved through the tubes and wiper boxes dead easy (with the wiper arms lifted or removed). Turned out I had a dent in the tube that was causing significant resistance.
3) Of course the commutator and brushes need to be in top condition.
Still no speed demon, but it's a lot better.
Ironically, the 2-speed wipers on my Stag run too fast even on low speed to suit me ... I may do a conversion on the TR if I ever get one on the road again.
