Last week, when I was explaining the problem to Tom and showing him the clocking issue and why he was having to "return" an irate customer's old rack, because their rebuilt rack wouldn't fit, he had never heard anything about the problem.

Neither had Ron, the purchasing guy, who deals with the rebuilder.

I just smiled and went about my day, after showing them the problems, rebuilding two racks last week and two this week.
I can see something like that happening in a large corporation with many layers and diversity of bureaucracy, but with a relatively small operation there's absolutely no reason for it.

We would like to see Mr. Anderson resolve this - quickly.

And this is why I have been rebuilding my racks for years.

If you want something done right, you gotta do it yourself! None of the racks I've rebuilt have had any leaks or come back for any reason.

I have enough trouble figuring out how to manage my own business, which is very small, compared to his. For me to even presume that I know how to manage his is absurd.

All I can do is point out the problem. I've done that, several times.

I too, have been quite fortunate with reliable racks. However, I see many "rebuilds" that are leaking after just a few years, while the original racks seem to last for many, many years.

I believe one of the "tricks" to reliable racks is to be certain that the seals get installed very "square" with the bores. I've hand made quite a bit of custom tooling to ensure that the seals get installed perfectly straight and at the perfect position.

Most of the "rebuilt" racks that I see have been taken apart and put back together with a hammer and a punch. What are the odds that whoever is "hacking" these things apart and back together is paying much attention to how straight the seals are installed?

Not very likely, me thinks.

It's the same old story...you get what you pay for.

Greg and/or Colin--

I have no specific knowledge of how to remove or install the pinion assembly intact. How hard is it? For the later racks, is it too difficult to a) take a picture of the pinion position with a rack centering bolt installed. Then b) clock the pinion in the rebuilt rack so it matches?? Even if the rebuilder doesn't do it (and he can't without the old/original rack in his hands...) is it something an owner/installer might do prior to installation?

Yes, this can be done. There are a few dangers in doing this. The bearings can be cocked, the lower pressure seal can be damaged, and the spool valve seals can be damamged, not to mention that any warranty offered by the rebuilder will be void.

I frankly got tired of having to do this, and decided if I had to take the racks apart, I might as well do the entire job.

Seemed, to me, like it might be easier to have it done right, in the first place....

Also seemed like any rebuilder, with two brain cells, should be able to figure out the original clocking and do it the same way, each time. Porsche certainly didn't have them made randomly and "hand fit" each rack to each car!

Sounds like only one brain cell is required to qualify as a 'professional rebuilder' based on what we're seeing in the rack rebuild market.



The pump has been replaced and the problem persists.

Looking at a rack rebuild.

I concur with Greg's response Bob.
