Mk2 Rear Wiper internals
#1
Hi all, just stripped down the rear wiper assembly on my Mk2 Multispace and thought someone may benefit from the pictures I took of the inside bits.

Obviously the plastic trim panel needs to be removed first. Two torx screws need to be removed from under the plastic strip on the handle. The panel will then pull off. Make sure you don't lose any of the plastic clips.

Remove the nut holding the wiper. I needed a puller to get the wiper off its shaft. The motor assembly is held on by 3 rivots. Drill these out. Remove the washer pipe and disconnect the electrical connector.

On the bench remove the plastic tube that fits inside the shaft. This carries the water for the washer jet and is probably what leads to most of the problems with the rear wiper assembly.

Remove the small torx bolts and carefully separate the plastic cover from the metal body. The brushes for the motor are on the plastic part and the motor itself is on the metal part.

The motor turns a screw which engages with the large plastic wheel. As this turns, the metal linkage rotates and eventually turns the shaft. I found I could turn the motor using a finger on the commutator, but there was a position where it was very stiff. The shaft on mine was sticking, so I took it out of the tube and cleaned it up. Tried again and it was free to turn all the way round.

On reassembly make sure the brushes fit to the motor correctly.

then use bolts to secure it in place

Or
I bought the 3 rivets & took them down to my local garage who fitted them in 2 mins for £5

regards

Only today and from that advert, did I learn those riveters work on a pull, not a push! A clear demonstration of the type of fringe detail you miss out upon, when self taught in mechanicals.

Any ideas where the "lazy tong" name originated? Is it because of the extendable grips they resemble?
