Anybody got a muppets guide for removing the wiper motor? got the new one comming tomorrow so i want to get it fitted asap

Ive taken the engine cover off, airbox, header tank/header tank bracket and took the 2 bolts out that hold the motor in place but can see how the motor disconncts for the metal coil that attaches it to the actual wipers.

Oh and the fuel cooler rail, does the aircon run thru this tube aswell? theres 2 petrol hoses on the top of the cylender and 2 metal pipes (aircon mabye??) one at each end, can i just unscrew these and fit the new one?

Cheers

I'm sure when I did mine, I just pulled the 'coily thing' out with the motor, then I could figure out how to disconect as I could see what I was doing. Once you have removed the back plate of the wiper motor, you'll see how it all fits together.

I've literally just finished repairing my motor and putting it back in.

I guess you've undone the large brass nut?

I couldn't work out how to disconnect the flexible rod from the motor. So I took the motor cover off, and removed the circlip that holds the flat rod onto the white gear wheel. then took the motor out leaving that bit hanging there.

Does that make sense? There must be a way of disconnecting it but I couldn't see how!

Thats exactly the way i done it, altho the new one i got had the metal rod already attached and the cover hadnt been opened, to get to the metal rod/wipers i would have had to take the small panel off thats rivited on which is nae gid

By the way what did you do to fix your wiper motor??

Well all that was wrong was that the wipers weren't parking.

The white plastic connector built into the motor actually contains a switch that does this, and it had failed. So I had got a new switch assy from Mini Partz - it just clips in.

Sorted.

And took the opportunity to fit new Leven wipers.

Must be something in the air - I did mine yesterday.
New park switch - although I didnt remove the coiled cable. I just undid the brass bolt and moved the wipers over. This gave me some free play so that I move the wiper aside to get behind it - if you know what I mean.

Replaced the Oil Pressure Relief Spring while I was at it. My god what a difference that made. very healthy pressure now when warm.

Hi Alan
Thats the part I fitted courtesy of Clever Trevor.
Took a couple of hours to do - the only tricky bit was getting the hose back on underneath the expansion tank.

I've just replaced the self-park switch on mine today. My advice for anyone else considering this task is simple: Sell the car. Far easier.

I'm just regaining the feel in my fingers this morning. laugh

Top Tool Tip: I bought one of those magrods from Frosts for a tenner-ish. Superb piece of kit. Longer than a normal telescopic magnet and made from plastic (except the magnets at each end) making it perfectly safe to use around car electrics (no sparks). It's flexible so you can apply decent force when poking it down a hole without it bending permanently.

Ah guys its not that difficult! Removing the battery helps but isn't completely necessary.

Remove bonnet stay bracket, bracket that holds expansion tank, remove top hose from tank, lift tank, remove bottom hose (a flexible drive with an 8mm socket on the end is useful here).

Remove U-clamp from motor (deep sockets useful for this), remove windscreen wipers, pull motor out a little, loosen large brass nut. Unplug electrical cable.

Withdraw motor, pulling flexible drive from tube - the wiper shafts will spin as you do this, thats why you removed the wipers.

With motor on table, remove cover (not necessary but makes it easier), unclup old electrical socket/parking switch assemble and clip new one in.

Reassembly (to use the time-honoured Haynes phrase) is the reversal of removal.

The Wiper Motor is a good example of why Cerbera's have such a bad reputation. TVR build a 190mph supercar and then fit a Wiper motor from a 1960's 70mph British leyland Mini !!

Thats just about exactly what i done when i removed mine apart from the bottom expansion tank hose, you can just push it forward into the space where the airbox was and the wiper motor comes out.

Didnt know about taking the wipers off and just pulling the cord out tho, i dissasembled the old motor still on the car to take the rod off. I take it that if you just pull it out that it just pushes back in easily??

Oh Sorry Adrian@, it was the 70's not the 60's was it? Well it must be alright then, its a modern design
Technically you may be right, its not exactly the same, but you understand the point I am making. I bought a Mini Wiper motor the 29w 'modern' version, after being told it would fit the Cerb. It didn't because the gearing was wrong, but apart from that it was identical to my original Cerb one, just the gear cog, and the cog housing were different, everything else was the same, so it is more or less the unit that is fitted to the old style Mini's! I think almost everyone will one day experience problems with the Wiper's, because they are a crap old design not suited to a 190mph supercar that when new cost around the £60k mark. If they'd fitted wipers from a Honda Civic they would have worked and never gone wrong.

A new improved version here

I think a more important point is to ask why the self-park switch apparently fails so often in the Cerb when they never seem to fail on the mini. I had minis when I first passed my test over 2 decades ago, and they were ancient then. It wasn't even something anyone ever talked about because they just worked. OK, that was pre-internet but I was a member of a decent-sized community of mini owners, all of whom had similarly ancient steeds.

Anyway, anyone know why it fails so often in the Cerb? Is it a heat issue, and could that be resolved with a little heat sheilding perhaps?

I dont know why it fails - I had a look at my old one and I couldnt see anything broken, just slight wear on the little nylon switch itself, it didnt look enough to cause a failure, but with the new one on, my wiper's now park properly (so just that small amount of wear was enough to cause a problem) But now they don't have enough ooomph to work ! maybe I need to grease my windscreen
