wiper rack tube

Postby Woodyalan » Mon Nov 29, 2021 8:08 pm

Hi
Am looking for the outer metal sleeve that takes the wiper rack from the wiper motor to the first wheelbox on later cars. It is about 33 inches long and has a captive nut for screwing to the wiper motor.
Thanks
Alan

Surely it should be curved, not straight - or is that why you need a replacement?

Only the first part of the wiper rack guide tube is curved, then you have the wheel box, then the centre guide tube which is virtually straight, then the second wheel box, then the short guide tube which is straight.

Agreed, and it's the first part from the motor to the first box for which the OP has asked. The photo shows a (nearly) straight section. I've never tried to straighten one before :-?

I assume he means part 16...?

Yes, it is part 16 in the diagram which should be curved. The trouble is I can't get the rack to pass through the tubing, either there is an obstruction in the tube or it is kinked so causing the rack to bind.

It'll surely cost you less to purchase what you want from a Minor specialist??

I'm sure most of them will have secondhand ones from dismantled cars. After all, it is not a part which usually fails.

Yes a quick look on google....looks like Moss do new ones might be easier if the other tubes are ok..not as satisfying or as much fun as making your own though :D :wink:

Ot even seems to be on offer at the moment. Note that it is shown as being straight. When you come to fit it, make sure that yo use a correct size tube bender - if you try to just curve the tube without the correct tool, then you will almost certainly kink the new tube.

I did contact ESM re secondhand tubing, you would have thought they would have loads of it, but they couldn't help. I have ordered new tubing from Moss though they don't supply the ready made item. You have to buy a 3 foot length and cut to the required size. It should come with flared ends and the nut fitted which will make fitting to the motor easy. At the wheelbox end it will need cutting to length and flaring. As long as I don't mess that up it should work alright. As regards bending the tube I figured if I insert the rack cable first I should be able to bend it to the required curve without kinking it. The cost is about 20 quid including postage which is fair enough.

Regarding bending the pipe, I’ve just replaced the fuel tank neck breather on my modern, I replaced it with 15mm copper, it has five bends.
The cheap tool I used kinked the pipe, using a pipe bending spring along with the tool gave better results but each time I had bend the pipe back a little to remove the spring. A floor standing record pipe bender I borrowed years ago gave perfect bends.
I’m not sure using the rack cable to stop the pipe collapsing and kinking will work.
I believe you can pack pipes tightly with sand to achieve a nice bend, the downside being a grinding paste inside the tube if you don’t get all the sand out.
Perhaps someone who has done the sand packing trick can comment.

You just flush it out with water and leave to dry :wink:
The hardest thing is getting sand into someone so narrow. You'd need to buy a bag of kiln dried sand, which is very fine.
