SN92 Strip Down Inspection.

[Blown V8 Capri]

Hi guys,
i have a used sn92 unit we bought to go onto our car this year,
is there a step by step guide on how to dismantle and what to inspect while apart?
is it a case of undo front and rear bolts and it pulls apart?
or is there retaining clips etc to remove on the shaft?
Had a quick search on the site and not found anything regarding this,
thanks for a great site

Just take out the case bolts and separate. A large o-ring seals it. Check the impeller shaft and make sure it is smooth and no nicks. Take a micrometer and make sure all the balls are the same size and have no nicks or grooves. Check the housing section that covers the impeller and makes sure the case has no impeller nicks. If the case has impeller nicks and the impeller shaft looks good then the balls are worn and no need to inspect them just get new ones.

You need to losen the impeller bolt, (locktide inside) then the bolts will drop.
The brass ball carier as well as the 1 ballrace look good enough to reuse.

Cheers Magnumpower,
would be handy as will get one made at work on the lathe then,
any dimensions etc even a rough drawing what it looks like with sizes scribbled on would help mate.

thanks again,

Ah a fellow Britt

Are the Europeans taking over this great forum ? :)

I took my dipstick and modeled it up and whipped up a drawing for you. Dim's are in inches. The Brit's will have to convert.

Material is whatever you choose. Stainless may look nice. Aluminum (Aluminium for the Brit's) may be too weak but will probably help dissappate heat better.

thank you very much JPJP.

I purchased a dipstick from CUNDN Racing via their eBay store. The price was very reasonable and saved me the trouble of having to make one myself. Could be an option to consider.

Here's a link: Paxton SN / GSS dipstick

Hope that helps.
