sulzerman Posted August 19, 2019 Report Share Posted August 19, 2019 Hi all The wipers on my 2500 are a bit slow and also seem to be jerky, it is not the blades as they wipe well. Watching the gear wheel and the pinion go round they speed up then slow down. See video I have greased the rack and it pulls in and out smoothly. I was going to replace the motor, but not sure if that would cure the problem. Are the replacement motors any good? There are Lucas motors on ebay but I am a bit dubious about the quality. Any advice gratefully received. wiper motor.mp4 Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 20, 2019 Report Share Posted August 20, 2019 It does look like rack load is slowing the drive , this may be lack of motor torque or rack loading. I would check the motor brushes there are three if ones worn down you dont get full power and the two speeds are then close rather than Quite different, did you turn the wiper box splindle 180deg to run on unused teeth when refitting the rack !! It can help with wear and tear. Pete Link to comment Share on other sites More sharing options...
sulzerman Posted August 20, 2019 Author Report Share Posted August 20, 2019 Hi Pete Thanks for the reply. The two speeds of the motor are similar so could well be the brushes, will check. I have done the 180 degree thing with the wheel boxes Link to comment Share on other sites More sharing options...
