Now, I think I have got to the bottom of the cooling pipe O ring (thanks jlbutlet81) and the fact it isn't needed for the turbo's as they use clamps and that it appears that the mechanical seal for the turbos is 19217657023, then I think my list complete for turbo's but will check again in the build.

On the stators, there are lots of options. The mechanical differences seeming to be 3 or 5 hole mounting (the stock turbo's have 3 holes and certainly some of the CX's do as well) but the 5 hole pattern seems to fit a 3 hole mount as well.

The turbo stator is a 24 amp @5000rpm/14v unit.

Looking at the table below and using P = V x A. The 500T calcs out to 24A x 14V = 336 watts which is about right from the table (340 watts), so as long as what we buy is in that zone or better it should be good.

There are a lot of official part substitutions during post-production years. Some fiches list them all, some only the most current. The larger seal has superceded the smaller (which is NLA from any known source), so the part listed for the early na models will be the larger one.

Finally got back to the bypass work, forced by a stator failure. I have rechecked all the parts from the previously posted list and will re-post later.

I have found a good site that details the work on standard CX's which I dont think is far off?


I plan to use this as a base guide.

I notice it does also go through oil pump checks which could be a useful thing to add while it is all apart?

I will probably get my stator rewound at custom Rewinds but does anyone have good experience with the DS ones?


Standby......

Those style oil pumps are pretty much indestructible. I wouldn't worry about the pump itself- just set the chain tension per the factory shop manual and you will be fine. It will take you about 5 minutes once you get the front cover off. There are no serviceable parts inside the pump anyway, unlesss you located a NOS pump which it doesn't need. You could machine the cover if you were desperate and even the gear faces I suppose. But I do not recall anyone on this site ever having a pump issue even with the age of these machines. For me, I just wanted to clean out the engine and reseal the cover :)

Nice posts. Thanks for the link. Would you agree that the site below is a good starter for the engine work?
