Steering rack hose adapters

[DougR]

I bought my rack from Van Cafe more than a year ago and never installed it Because I had an engine failure. Now that that’s taken care of I started the install. I have everything in place and was about to move the hose adapters from the old rack to the new rack and they don’t fit! The threads look clean on the old rack, the new rack, and the adapters. The adapters going about one and a half turns and then bind. I don’t want to force them. I don’t recall what brand the rebuilt rack is, but I think it’s Meyle. Has anyone had this experience, and what did you do?

I understand these fittings are really hard to find. My tap and die set ends at M 12, but the threads on everything look like they are 1.50. The plastic cap that covers the opening fits both racks nicely. Any advice is appreciated.

Thanks! Doug

Have you asked the place you bought it? If so, what did they say?

Not yet. They were closed when I called. It’s on the list for tomorrow.

A rebuilt rack would be compatible as it's a ZF unit (VW).
The newly made ones are most likely JP Group, I've installed a few, the threads are also the same, but that could have changed on a new unit.

That is odd...

I filled out the, “ask an expert“ form on an Cafe’s website. I immediately got a response that said they are having an unusually high volume of questions. I’m pretty sure it says that year-round. Anyway, I’m sitting here high and dry until I figure this out. I think I’m going to try my local Ace Hardware store and see if I get some matching bolts and see how well they thread into these openings.

Fill the (oiled) hole up with some dollar-store playdoh, then carefully unscrew. Measure the threads.

I’m not going to stick Play-Doh in there. I like the way you’re thinking, but that makes me nervous. I just bought a thread tester. It will be interesting to see what comes of it.

I would use a thread pitch gauge set and calipers.

[DougR]

Tried the thread tester. Same results. Won’t go past 1/4 to 1/2 turn. My tap and die set has a thread pitch gauge. That with a camera and I can see that it looks like a 1.5. Calipers tell me it’s M16 and M14. The plastic cap that came with it is a perfect 1.5. Really hard to see into this cavity after the rack is in place - so annoyed that I didn’t do this before the rack was installed.

this type of tool has been invaluable at times.

Look also that there's no nicks in the female threads, who knows, but it looks like the tooling was off that day in China. They don't check for deviations and recalibrate every 2 blue moons, poor QC that let this one slide is entirely possible.

Try something with 1.25 pitch or send a clear picture, I can tell most threads sizes and pitch by eye but in real life.

Measure the fittings going into the rack, a bottoming tap should clean up the rack threads quickly.

In a pinch, I have made a thread chaser using a proper size bolt and cutting lengthwise slits into the threads.
