peejay4A Posted September 13, 2012 Report Share Posted September 13, 2012 Does anyone know if the Moss part AAU1909A comes pre-formed to the right shape? I'm not convinced that the one I have is original to the car and it's not looking pretty. Thanks. Quote Link to post Share on other sites
RogerH Posted September 13, 2012 Report Share Posted September 13, 2012 Hi Pete, if it comes pre-shaped I would guarantee that it is the wrong shape. Cynically yours Roger Quote Link to post Share on other sites
peejay4A Posted September 13, 2012 Author Report Share Posted September 13, 2012 I hope that's not the case Roger. It seems to me that this is the part of the tubing that needs to be curved as smoothly as possible so as to ensure the least resistance to the rack. I tried to make the one I have fit but it needs a compound curve and it's hard to visualise where the bends should be. Quote Link to post Share on other sites
RogerH Posted September 13, 2012 Report Share Posted September 13, 2012 Hi Pete, are you sure about the compound curve !!!. I thought it was a simple curve and should be do-able with simple tools. Roger Quote Link to post Share on other sites
stuart Posted September 13, 2012 Report Share Posted September 13, 2012 It will come straight Im afraid. I have been making mine up from copper tube to make bending easier. Stuart. Quote Link to post Share on other sites
JANA Posted September 13, 2012 Report Share Posted September 13, 2012 Peter, Yes it is curvede for sure, and I agree the curve is critical. Bob Quote Link to post Share on other sites
peejay4A Posted September 13, 2012 Author Report Share Posted September 13, 2012 Thanks folks. I found that the AUA part has to be flared so of course it has to be bent too. Maybe a s/h part is the way to go unless anyone has a pattern for the bends? Quote Link to post Share on other sites
AlanT Posted September 13, 2012 Report Share Posted September 13, 2012 You have some chance to find NOS or used on Ebay. I wouldn't use a straight Moss one if I could help it. Original Lucas p/n for this tube is 54713140. If I was bending this I might try it with the rack-spring left in. This way it wont collapse. If its only the flare thats wrong there is probably just enough length to re-flare it. You dont have to make a perfect flare like a brake-pipe. There is not much pull on the tube. But it is a funny shape. Al. Quote Link to post Share on other sites
peejay4A Posted September 13, 2012 Author Report Share Posted September 13, 2012 Cheers Al, it's the shape that's bothering me. The one I have is misshaped but the flares are fine. I probably could rebend it but there's only so much trial and error that it will take before becoming kinked to blazes. Quote Link to post Share on other sites
stuart Posted September 13, 2012 Report Share Posted September 13, 2012 Fill it full of fine sand before bending as that should help to retain its shape. Stuart. Quote Link to post Share on other sites
AlanT Posted September 14, 2012 Report Share Posted September 14, 2012 Well it wont want much heat to make it bend easily. Dull red with a butane torch I would think. Two pieces of rod one in each end to make "handles" and just heat the place you want to persuade a bit. I chrome plated mine. Al. Quote Link to post Share on other sites
peejay4A Posted September 14, 2012 Author Report Share Posted September 14, 2012 It's not really the act of bending that's a problem. I just don't know how it should be bent. Quote Link to post Share on other sites
AlanT Posted September 14, 2012 Report Share Posted September 14, 2012 Post a photo of this. Its not long since I fitted mine and I have a fair idea how they should look. Al. Quote Link to post Share on other sites

AlanT Posted September 14, 2012 Report Share Posted September 14, 2012 If you photograph the bent tube and put it on here so I can see it then it would help me to explain to you how to bend it so that it would fit. I will be able to tell how much bending you need to do. However in case you cant photgraph it I will explain how I fiited mine. I put the two wheel-boxes in place with the tube between them The tube that comes from the motor enters the wheel-box in line with the tube between the wheel-boxes. Dont fit the motor yet. Dont fit a rubber grommet. I put the tube through the hole in the bulkhead and rotated it about until the direction into the wheel-box was correct. Now compare the angle of the tube as it goes into the nut with the hole in the bulkhead. Pretty much the tube comes through perpendicular to the hole in the bulkhead. In other words that funny dented-in plate gives the clue as to the direction that you need the tube to take at the motor end. It has to curve down about at 3in from the wheel-box to get through the hole. But this would make the angle wrong and you would not do up the nut. So about 2in from the nut end it tips back up a bit so that the nut points at the motor correctly. Both these bends are quite gentle. 15 degrees or less. You got a kind of very lazy S-shape with the two ends not quite in the same line. I would probably be able to bend this with my thumbs alone on a new tube. Maybe at the nut end its too close to the end to bend it by hand and I'd slip an extension rod in the end to get a bit of leverage. If was badly over-bent already then I'd heat to cherry and leave to cool to reduce work-hardening. I would resist the use of any vice or grips or such in case I dented or squashed it. I might mount a 2in diameter bar in my vice and push the tube around it. But only after I'd tried just by hand. Al. Quote Link to post Share on other sites
Ocheye Posted November 26, 2019 Report Share Posted November 26, 2019 I have a similar problem with my motor to wheel-box tube. Mine must have sheared off at the wheel-box end at some time in its' life but there is no sign of the flange inside the wheel-box. If anyone knows the precise length of the tube it would help (if I need to order one) and any pics showing the curves would be extremely useful Andy Quote Link to post Share on other sites

Is this definitely the same size and curve as it appears to be listed for a mk 3 mini here. http://www.minispares.com/product/Classic/AAU1909A.aspx On enquiry this would appear to be 203mm long whereas mine is (best guess) 235mm Andy Edited November 27, 2019 by Ocheye Quote Link to post Share on other sites

Grahamgl Posted November 28, 2019 Report Share Posted November 28, 2019 Andy, Currently there is a set of TR6 rack tubes on EBay with a Buy it Now price of £38.95, I can’t find the item number but the seller is “948s”. Graham Quote Link to post Share on other sites
rcreweread Posted November 28, 2019 Report Share Posted November 28, 2019 Guys Here are some not very good photos of a rack and tubing from a TR4 - rushing about today a bit so no time to do a proper measuring job, but can do if photos are not good enough when I have a bit more time. Should hopefully help Cheers Rich Quote Link to post Share on other sites
John Morrison Posted November 28, 2019 Report Share Posted November 28, 2019 Really helpful photos Richard, many thanks. Just one question, picture one, showing teh tube that goes from Wiper motor to first wheelbox, can see the radius clearly, can you just tell me is the tube flat, i.e. only curved in one plane? John.

John - no it isn't flat but that isn't to say someone hasn't bent mine at some point in the past - I took it out of a bulkhead I was stripping out which hadn't been accident damaged and I don't recall bending it to take it out so it could be the original shape. Some more photos of the first bit next to the motor to try and show the curves but as you can see, I'm no David Bailey! Hopefully it will help a bit Cheers Rich Quote Link to post Share on other sites
