Pinion Valve

[KennyW]

Hi Gang,

Silly question time, has anyone stripped a Pinion vale down apart from Martin @ Pleiades, how do you remove it from the rack and does anyone have a copy of the diagram from the citroen service site.

Second point, my rack would appear to have had fitted 2 different track rod end ball joints as there is 2 different isze nuts, any reason for this.

its held into rack with two allen bolts, and you need to loosen the upper column UJ which then allows the lower column to be pushed up off the valve

the valve is a tight fit.

its quite hard to remove it.. there are also ?4 hydraulic pipes to contend with.. I did it twice in situ, but only after initial removal with eninge out first! not sure if removing the whole rack first wouldnt be easier..

See my blog for some pics of the valve

I tried to rebuild it but it was out of my league so brought one off Martin and put it down to one of those things - was very grateful he rebuilds them as driving with no power steering (or working one way only) wasn't too easy

Thanks for your reply John,

I have read your blog, very interesting and informative.

Probably the nuts are 16mm and 17mm? 17mm is the standard size for M8 (or is 10) threads, but citroen use 16mm, so one will be an aftermarket jobbie.

thanks Kenny

the unions Rich? got a feeling two are 13's and two 11's but they are hard to get to,, what job is rack removal on a xantia?

[citronut]

i would have thought the larger pipe fittings at the pinion valve are 12mm
and they are usualy FT tight

Thanks for all the relies,

After a conversation with Martin @ Pleiades I will get a recon Pinion valve and fit same onto my rack.

Will replace the T/E ball joints with new but looking for a source for N/S gaiter, GSF don't do it for later xantias.
