      On a rally last Sunday (in the rain) my wiper motor packed up and judging by the excessive heat and sticky brown stuff dripping from it, I think it is burnt out and I need to remove and replace it.  However, having removed the spindle bushes and loosened the whole assembly, I can’t seem to get it down and out – does the manual operating knob shaft have to be dismantled first?  Has anyone done it?  Many thanks in advance…

        This is probably the most difficult job to access on a French built traction!
        The topic has come up before – see https://traction-owners.co.uk/forums/topic/wiper-motor-gearing-problem/

        Basically if you remove the glove box – screws inside it, and the battery followed by bulkhead panel behind, you should be able to see and access the wiper motor. There is no need to remove the mechanism, the motor can be removed separately.

        A new motor should be available from club spares, but you could ask Chris if he has any working second hand units – some were purchased from Andy Burnett at the end of last year.

        Good luck

          I don’t envy your task as I spent many hours and  a lot of bumps and scratches on my bold head, getting into shapes you wouldn’t think possible. The topic that Peter refers to explains in full technicolour the difficulties  I experienced, it should be of great help to the completion of your task.

          I thank Peter for the Memories.

            Thanks Peter, thanks Davy, have spent today upside down on the floor of my traction and managed to extricate the whole wiper assembly – quite tricky with the manual operating shaft firmly in place.   I then stripped the motor down to its component parts and cleaned out what looked like dark brown resin from around the cogs.   Having thoroughly cleaned it all and reamed the bushes, I reassembled it all, greasing and oiling as appropriate, and then realised that the manual operating shaft had seized in its bush and had been working the lock nuts loose every time the wipers were switched on.   I then realised the shaft extension could be removed and once the shaft and bush had been freed up and the bush locked back into place, it made inserting it all back behind the dash so much easier!   Now the wipers work properly again and are noticeably quieter – but I have been working on it most of the day and it hasn’t cost a penny!

              Hi

              Well done, you certainly must know your stuff mechanically and the remedial works carried out should insure no further problems. Cristal clear windows on the next rainy day.

              Keep Well

                Ditto on the well done. A pig of a job but had to be done. My motor was seized because the grease inside had gone solid – like resin as you say. Will check on the rest of the mechanism now to see if the bushes are starting to seize also, as it still occasionally seems to lock and has to be persuaded to start with a wiggle under the dash…….

                  The reason you have to give it a wiggle sometimes is the rubber bushes are more than likely perished and not able to hold the motor against the driveplate. New rubber bushes will be able to support the weight of the motor and hold it in drive, which is what happens when you reach in and wiggle it back into drive.  If you are not able to obtain new rubber and metal inserts you will be able to covert tube valves to suit as per my earlier posts.

                  Keep Well

                      Actually I did replace the bushes when I rebuilt the motor Davy. Had some left over from a jukebox rebuild where they supported the turntable motor. What seems to happen with mine is that the mechanism seizes – locks solid. Fiddling with the actuating rods to one or both spindles gets it going again. Hasn’t done it for some time now and all is well lubricated so I hope it has recovered. I’m certainly not going to dismantle anything until it happens again………
