Hi all, just fitted a new old stock wiper motor that was given to me however it seems that it may be a left hand drive variant (if such a thing exists!) as the wipers are parking the opposite way. Is it possible to reverse the motor to make it park the correct way for rhd cars?

odd as the LHD motors were fitted on the other side of the car.

Can confirm that. I have a LHD mini and have worked on RHD minis. There's a few odds and sods that are just swapped left to right. The wiper motor is one of those.

The parking switch is 180 degree out.

Any tips on how to correct this?

Adjustment depends on the type of motor you have. If there is an earth wire attached to the raised cover above the driving cam wheel, as fitted to some early wiper motors, the small fixing screws that held this cover in place can be slackened off and the raised cover would turn. This cover had the park switch earth return insulated section fitted . If your lucky enough to have this type just rotate the cover till the parking position is correct then nip up the cover screws.

If not take the motor to pieces and find how the self park is initiated to see if it is possible to change it.

The wheel boxes aren't on the wrong side of the rack are they?

If it's not that, you may find a selection of holes in the plastic pinion wheel for varying the fitting of the drive crank according to application.

I was thinking this but it is not easy to do.

 

and again we need to know early or late wiper motor.

Most look like this ... or did when I was fixing them ...

The round cover with the wire attached can be move, but take care as it has a small brass connection inside so should only be turned one way .. and it's a very, very long time since I looked at one!

 

 

Must admit the round-body ones don't look as simple!

As suggested by Ethel's comment, you could try intentionally reversing the wheel boxes, if you can get them to fit properly and the drive cable guide tube still has a nice smooth curve. That avoids messing about with the motor. But the remarks about moving the parking switch are also valid, whichever is quicker and easier for you to try. Might depend on what tools come tools hand first.... It might be a good idea to have the wheel boxes out anyway for cleaning and greasing. In most cases it will not have been done since the car was made! Nowadays that is at least 2 or 3 times the design life.

As an aside, the only reason I happened to read this thread is that the title suggested to me a reverse parking motor, which does exist. The crankpin is in an angled slot in the gear, so it is pulled inwards in normal running, giving a shorter stroke, and when the motor is reversed to park it moves to the outer end of the slot, giving a longer stroke and taking the blades below the normal sweep area. My old Rover P4 had one, and there is no reason why a Mini could not be equipped with one. They use the square motor body and the parking switch can be rotated to adjust the position. Needs an extra wire and a different switch. I was sort of hoping that you were going to ask about fitting one, just because it would be something different.

thanks for the replies the issue is now fixed and all is working as it should. The wiper gear assembly was already installed in the car so the wheel boxes were already correctly orientated and were the same that came out of the car, only the motor was changed. The motor was a new old stock one given to me by my neighbour. It visually looked identical to the old one however i believe now that it may have been intended for another bmc/leyland car as the gear inside was orientated the opposite way round. Simply disassembled swapped it round and wipers now park correctly. The link below explains the issue a bit better!
