Wiper Motor for Series Two

[Boomlander]

Hi All,
Does anyone know the correct wiper motor model for a Series 2 Minor?
I've seen a DR3A advertised or will any motor do the job?
Thanks.

I believe the original type would have been a Lucas CRT14, part number 75151 for a Series 2.

Later cars had DR2 motors, but two different variants

There are many variants within each type - a DR3, for instance, can be 1- or 2-speed, and there's a range of sweep angles for all of them. Aren't DR3 the ones that do a fancy dance when you turn them off, so they park off the screen?

Safest to stick to the original type, or you may need a special switch and extra wires. Or mend your old one?

Many thanks, I may try a renovation on the old motor as it works but very slowly.

have you cleaned out the old grease? and replaced with fresh.. there might not be anything wrong with the motor so no need to renovate it.. ( by renovate i assume you mean replace bushes etc )

As charlie explains - slow running is likely due to seized up wheelboxes and rack! First move is to run 3 in 1 oil down the wiper spindles and see if that helps. But the long fix is a strip down/clean out/regrease job.

As you can see from the drawing, the wiper motor sits behind the inst. panel or glove box on the driver's side. The motor is secured to the bracket by three rubber mounts, these are often broken off and a new mounting plate is required. Take care when removing the four nuts and bolts holding the bracket to the body or you may lose them down the A post.
To remove the rack and motor in one unit, remove the wipers and spindle securing nuts and push the spindles into the car, the assembly can then be withdrawn through the glove box opening

I have driven several Morris cars of the early 50's including an Oxford MO and Morris Six, both with varying wipers. One was so bad I asked if they were vacuum wipers! On my S.II the wipers go fast enough, equivalent to what I would say is a 'constant' setting on modern cars, getting faster as the dynamo cuts in and the battery is fully charged!

At the end of the day it's all character, I like the single speed motor even in driving rain.... you should have seen the cleared arc when the screen was fully snowed up. I almost took a photo of it and wish I had now.

I like the fact that you can park the blades wherever the hell you like.

Many thanks, I will certainly give it a try

Yes I am going to take out the motor and rack and overhaul it if necessary or it could be a loose wiring connection - I've had a few of those lately !

one tip which I did if you are going to re furb, make sure you turn the spindles when refitting so that the unworn part of the wheel now touches the drive cable,unless it has allready been done at some stage in its life(Probable) makes a massive difference if possible

Excellent tip! Many thanks

To do that - you need to mark them before you start, so you KNOW they have moved round when you re-assemble.......

You're quite right, thanks also for advice

Hi All,
After running a drop of oil down the wiper spindles today I switched on the motor and the wipers began to move up and down, albeit with a helping finger underneath one of them. It does seem that the motor is running but lacks grunt.

[bmcecosse]

More oil.......

[Boomlander]

I think I will definitely take everything out and lubricate the entire system.
Had a hard time looking for the motor behind the dashboard - then discovered it's located behind the passengers glove box! DOHH!

[Boomlander]

Discovered that the wiper motor is indeed a LucasCRT14 and was located behind the passenger glove box sitting on a strange cast iron pedestal bracket with a "C" shaped top which held the motor body by a single screw, the base being held to the inner glove box compartment by two further bolts.
After removing the motor I took off the gear cover and found clean fresh grease in the gear housing and also checked the free movement of the cable and wheelboxes which ran back and forth very smoothly and easily.
I then connected the motor leads to a spare battery and it ran with no apparent problem. I refitted the motor, connected the drive cable and switched it on without the wiper blades fitted. Both spindles turned with no slipping or noise.
The wiper blades were then fitted and on switching on the motor it moved the arms a few millimetres and then stopped.
The screen was wet so offered little resistance to the blades so it seems that the motor itself, although running without load,
is in need of complete overhaul or replacement as without wipers the car will fail its MOT in July.
Such a shame when the rest of the car is in such good shape!

Decided to play safe and ordered an exchange wiper motor from ESM.
