Wiper delay

[happy days]

No matter what foam I use I can't get any longer delay than 5 seconds. So now thinking the tube from the delay to the switch may have a pin hole or small split in it. How do you get access to the white switch on the steering column ? Does the shroud have to come apart ? I am leaving the old tube in, just going to run a new one.

There's a join in the vac pipe, presumably so you can remove the column without taking the nacelle off to disconnect it at the switch, so I'd look there first, it's up under the dash close to the column support.

Ok thanks. Will connect new tube to that. Failing that how do I get to the switch

[harveyp6]

Remove the steering wheel and then you can dismantle the nacelle to get at the switch. Don't remove the nut completely when pulling off the wheel. Remove the nut, remove the shakeproof washer, then screw the nut back on. Cosmetic Dentistry is expensive these days.

Thanks Mr H.

Before you do all that, put you finger over the recess and seal where the foam goes to see if the delay gets any longer. This will tell you if the delay membrane is good or not.

Paul, to late I'm afraid, left the old tubing in and ran new from delay to the section Harvey said under the steering column, made no difference. So removed steering wheel and put new tubing to the switch and no difference. At least it's ruled out the tubing. So bit late now and too dark but it's your idea next Paul. Failing their then the 5 second delay it will be

I was about to suggest that before you remove the wheel, mark its position on the column and the wheel itself...

[happy days]

Did do that Willy, don't know why I did but whenever I remove anything it is marked or photo taken, good advice though.

Yesterday I reacquainted myself with the vacuum delay on the v8.

I had dabbled with it but eventually took the decker off and removed it from the car.

After reading your thread I was a tad confused because I previously fixed one with some insulating tape to cover the sponge bit.

Like test rider says put a finger over the bit where the foam goes, and also pull the pipe off and put a finger over the end of the vac unit. push the plunger in and see if it stays in. gently life a finger off if it stayed and make sure it comes all the way out. Do this without the motor running.

I eventually found that the unit was duff as the electrical part was not up to it and swapped it with my spare.

Cleaned greased and tested it ot be ok. with plenty delay. as you are getting a delay it must work just not well enough. has the clips rusted or fallen off? the unit it actually 2 part with the diaphragam inside it is possible you have a leak here.

Tested today as Paul said and the plunger very slowly dropped, so as Colin suggested looked at the clips, I had 3 clips and on closer inspection their seems to be a correct place where the clips should sit. Moved the clips to the correct place and added a fourth clip. I now have a 12 second max delay. Happy with that, nearly doubled previous delay by moving the clips and adding one. Cheers for the help guys.

Glad you've sorted it to your satisfaction Mick

The beauty of these old Rovers is that most things are simple fixes, might take you awhile to work it out but you get there in the end

And that's where you guys come in so handy........Happy days

Greetings All,
My delay has never worked either.
This one seems open to a fair degree of debate considering it is a small, insignificant piece of foam sponge. What should I use etc.? too thick ? too thin? open cell/closed cell?
I hope that my efforts today may help.
First of all I think the material is important. I applied my lateral thinking and 2x cans of lager......
The result was almost too easy. Grab your wife's old "Abroller 2000" or her "Bum-away 500" (or yours ), you know the ones, buy 'em for christmas with all good intentions ("Gonna get abs like Arnie ), shove 'em under the bed on boxing day!!
The padding on the handles on these cheap Chinese exercise things is perfect. Cut a piece to size making sure that it is not too deep. From what
I can tell 4-5mm is deep enough. As the sponge has some smoothe surfaces make sure that they are removed so that the "cells" are exposed on all sides (I hope that makes sense...)
Refit the cover and clips and wa-hay!!!!!
I now have 2-3 seconds with the switch wound one way and 7-8 seconds with it wound the other. Result!!
