Steering Box Specialists?

[Radders226]

Hi, 

Does anyone know of any specialists that can rebuild a steering box for a pre-aeroflow Mk1 Cortina, preferably in the Essex area? 

I've been told that they can be adjusted, although not by any Steering box experts, or by anyone that's ever done it, if you know what I mean. 


Thanks.

They can be adjusted, there is i square headed bolt and lock nut on the box.

that can be adjusted to take out the play/wear in the box.

Hi, 

I've been told that the aeroflow and pre-aeroflow steering boxes are different, so are they both adjustable? 

Do you have any pics of what the square headed bolt and lock nut look like, because I cant find it on mine. 

Thanks

All steering boxes are adjustable.

I would get yourself a repair manual, and read up on the correct procedure.

Its the bit in the middle of the end plate on the left of the pic.

this company in byfleet is probably worth  talking to

I had my mk2 cortina box rebuilt many years ago (by another company) and was advised to refill it with ep150 oil rather than the manufacturer  recommended ep90 , this should mean it will never need another rebuild

If the box is worn it will be  in the centre of the steering  travel so adjusting to try and reduce that will mean the steering will be tight  at its limits .

normaly the worm will need to be built back up and re machined to ensure that it is straight and parallel  to give  smooth operation .

Mk1 do not have the adjust nut normally thats mk11 steering box or its from an import maybe?, Mk1  boxes are only adjusted with shims under the top plate, and shims at the bottom of the column

a bit late reply maybe?, adjustment on Mk1 one is done with shims under the top plate, if you look for Theo Cupia on Retards Club he sells full rebuild kits, the hard bits doin it yrself is first getting the Pitman arm off they almost seem like there welded on!!!!!!!!!!!! i've broken puller on them, serious heat helps whilst under puller tension, I force wedges under the arm then heat nr cherry red the arm, then leave to cool off naturally (hours) they usually come off then, the other hard bit, two sets of hands really is keeping the bearings in place while you insert the steering shaft and get it bolted down, fill it with Penrite grease not oil, you can buy steering box grease on ebay, then you have to check preloads then take apart again to swap shims!!!!!, a right pain in the ass job to be honest.
