Graham Posted August 7, 2022 Report Share Posted August 7, 2022 (edited) Just interested in the differences between the 5 and 6 wiper systems, can anybody enlighten me ? TIA Graham Edited August 7, 2022 by Graham Quote Link to post Share on other sites
BlueTR3A-5EKT Posted August 7, 2022 Report Share Posted August 7, 2022 (edited) The switch, 3 terminal then 4 the motor, armature has overwind circuit then offset brush for speed control. the wheel boxes, gain teeth on tr6 by having larger diameter rack driven gear. Different visible chrome nut and it’s thread to hold washers jets in place. Not interchangeable.! the width of the wiper arm that plugs into the blade. not desperately important Needs matching blade though. Tr 6 used low reflective or black. The wiring has extra wire on TR 6 from switch to motor. Mounting bracket for motor complete change of how it’s done. Rack and motor remain common.

Did the changes provide any wiper improvement on the 6 do you know ? Quote Link to post Share on other sites

Yes the round bodied 14 W motor is stronger with more torque to improve wiping. As compared to the square bodied DR3A two speed unit. Tends to be more reliable and resistant to being stalled. That said it is still a fairly basic item that relies on the strength of the rack and wheel box system. A modern eccentric crank system would be far more durable. See ‘Project Binky’ on U tube for adapting a modern system to replace the classic Mini rack and wheel box set up. Quote Link to post Share on other sites
