Re: Heater valve !

I'm about to give up on my London taxi heater bypass valve. I just can't find a way to mount it without having impractically short lengths of hose, with tight radius bends. It has 16mm connections, I have a 16mm stub connection in the block, and I have ½" adapters to connect to the heater radiator a...

Re: Heater valve !

As an alternative I have fitted a 3 way valve inline to the heater. I use the 5/8 outlet from the block into a 3 way valve. This either feeds the heater or if closed keeps the water circulating back to the block. It's worked OK for a couple of years now. The one I bought was for a London taxi. I've...

Re: SU carb overfilling

Success, it no longer overfills when connected to the fuel pump. I have now got it running, but it's a bit rough and lumpy, not idling smoothly. I've only run it for a few minutes, more or less with the carb at the initial settings recommended in the SU tuning guide (mixture control adjusted so that...

Re: SU carb overfilling

Thanks. Good tip. It's an HIF, so the float chamber is integral to the carb body. I got a piece of rubber pipe, connected it to the fuel inlet, and tried sucking on it. I couldn't maintain a vacuum in the pipe, either with the new needle valve, or the old. I tried the same trick on the HIF 38, and h...

SU carb overfilling

Hi all. I'm fitting an HIF44 to my 1275, in place of the HIF38. I have rebuilt it with new seals, jet needle, float chamber needle valve and seat. The problem I have is that I can't stop the carb overfilling, despite following the Burlen website guide on setting the float height (1mm +-0.5 below the...

Re: Brake lines-minimum bend radius?

Steady progress. I bled all 4 wheels last night, virtually no pedal at the end, so I left a heavy weight (spare cylinder head) on the pedal overnight. Bled all 4 again this evening, and now have some pedal, though not really biting until a bit more than half way along its travel. I've left the pedal...

Re: Brake lines-minimum bend radius?

Thanks Phil. Bit late to do anything about the brake adjusters now, the wheels are on. I could apply the handbrake, but I guess that will also move the cylinders in relation to the pistons? I have the car raised on blocks of wood (on its wheels) currently, just to make it easier to get under. I migh...

Re: Brake lines-minimum bend radius?

Ok, bleeding the brakes now. I filled the reservoir last night and left it overnight. Sure enough, there were weeps from some of the unions. I nipped them up, tried again with a few pedal strokes, and most stopped, one or two required several goes though. They seem tight now, and I am starting bleed...

Re: Brake lines-minimum bend radius?

Thanks. Judgement I guess! I know I have nipped them up too tight in the past, and had a leaking joint as a result.
Cheers, Neil

Re: Brake lines-minimum bend radius?

Long time, little progress, but I am now at the point of tightening the brake line unions, refilling and bleeding.
How tight should the brake line union nuts be? I can't find any reference to this in any manual.

Re: Brake lines-minimum bend radius?

Slow progress. I have new flares on the master cylinder-servo pipe and the front 3 way to rear hose pipe now, but still waiting the back axle pipes. While I'm waiting, I am fitting the two pipes I have ready. Try as I might, even though I measured and bent the pipes to shape, I'm finding it really d...

I have a friend who used to be a service engineer for the RAC, he's going to do them for me.

Re: Brake lines-minimum bend radius?

Hello again all. Got the flares done by a local friendly garage. However, not too sure about a coupe of them. There is a bit of a ridge where the die blocks meet. What's the view? Are these useable? I'm a bit reticent to go back, as the guy did it while his boss wasn't looking, and I'm not sure I ca...

Re your picture of the pipe from the master cylinder:-

Make sure that the pipe is straight for at least an inch from where it exits the union nut before curving up and over the cross member. If it is not straight it can lead to stress and ultimate fracture/failure.
Ok, noted, will do. Thanks.

Final position of the new line from the master cylinder...... IMG_20200219_211706~2.jpg ..... And the new route between the clutch pedal. Compare with the photos I put up earlier in the thread, it's much better. IMG_20200219_211756~2.jpg I still have to get flares put on, so this is not the final fi...

Re: Brake lines-minimum bend radius?

I have made up new Kunifer pipes from the master cylinder to the servo, front 3 way union to rear flexible hose and the two pieces across the back axle. These last two were copper, the others were Kunifer, but I wasn't happy with the routing. All my brake lines are now Kunifer. In other news, after ...

Re: Brake lines-minimum bend radius?

Is it ok to re-use brake lines? The ones across the back axle are about 5 years old, copper, and look good. No obvious sign of stressing or cracking, the flares look good as well.

The brake pipe should go above the cross member and as Les says it should be sheathed in a split rubber sleeve to protect from chaffing.
See picture below.

Phil, have you got a servo fitted as well? There seems to be two pipes going over the cross member.

Re: Brake lines-minimum bend radius?

Ta. I thought it was best that way. I routed it through the cross member when I fitted the servo, but I've never been happy with the tight radius curve, and of course moving the cross member is more difficult. I've now got a new piece of Kunifer pipe in place, ready to cut the end to length and get ...
