Tr250 wiper motor refit


Recommended Posts

Hi All,

 

A mate over here has had issues with his wiper motor in his TR 250 whilst on a recent trip to France.

 

Hes now got a rebuilt one that he wants to fit. However hes having problems and cant work out how to remove the old one from the engine bay.

 

It cant be difficult but he seems to think it is, hes not a spanner man but tries , bless him.

 

Can anyone advise me on this, I havent had a look myself yet.

 

 

Thanks

Guy

Hi Guy,

nice to see you back.

 

This is how I did it just a few weeks ago on the 4A (same motor).

Remove the wiper blades

Undo the big nut at the front of the wiper motor (3/4 AF)

Remove the one screw you can see in the engine bay

Remove the two screws inside the car on the bulkhead immediately below the motor.

Pull the motor towards the wing and forward.

Remove the four little screws holding the lid down. Put a mark on the round dome (self park) so it goes back in exactly the same position.

Remove the lid.

Remove the 'C' clip holding the self park contact, remove the clip.

Lift the oscillating plunger from the gear wheel

 

Remove the motor body.

 

Refit is opposite.

 

If you have a decent auto electrician on the island they should be able to rebuild your old one.

Hi Roger

 

Thanks for that.

From you detailed description, he hasn’t found the two screws in the footwell.

 

Cheers

They are just under where the plenum bulges out, you may find the eyeball hose is in the way.

Undoing the bit nut can split the motor casing if it's tight or cross-threaded.

 

Use an adjustable spanner to support the casing.

 

OR

 

Pull the horseshoe clip, lift the crank-arm out and release the wire-rack from the motor casing without undoing the big nut.

The part that holds the wire-rack nut/nipple is really pretty weak and will NOT stand any abuse.

 

If you have removed the cover-plate it stands no chance of acting as a "spanner".

 

People often try to remove these by prising up the crank-arm to free it from the rack-end. This works in the sense that you can get it out.

But you bend the arm and may pull out the big-end bush.
