    Found this which may have a bearing on this.

    I checked my steering last night. With the steering straight ahead it is about half a hole out on the rack.

    Lock to lock is about 1/3rd turn out one way, so not too bad.

    I've also ordered a 13" blue and black Mountney steering wheel to bling things up a little more..... now to sell off the 12" one.....

    Please be careful with this approach Hugh. It is well documented that the older cars like ours had a greater lock on the left turn than on the right turn. Triumphs especially and I think the marina steering rack is based on Triumph. I originally did what you suggest and spent ages getting it spot on as I was suffering from bump steer. Then discovered that i had to wind the right hand track rod end out too far to get the wheel straight which left very little thread still in tact. I then looked at the centre point alignment hole which was way off. So centred the rack using the hole and now have exactly the same number of thread turns on the track rod ends for both sides.

    I have to agree. Focusing on a hole that at best is intended for centring the rack during assembly, but quite possibly is only an oil fill hole, misses out on the significance of track rod end thread engagement and the more significant issue of wheel alignment.

    Hi Steve
    In post #21 by Adrian the Marina workshop manual clearly states that the hole is for centralising the rack for "refitting to the car" and centralising the steering system to the car. Although I believe in checking and double checking these things against safety and quality, taking into account variations that creep in due to many years of fettling(fiddling), the manual is the usually the correct starting point. It certainly proved to be correct for my specific installation.

    i fail to see how the rack can be centred when it’s position is dictated by the construction of the rack, and it’s flanges where the rack body is secured by its saddles. The position of the rack is non adjustable!

    Surely the reference by the manual refers to the 'rack' being centred relative to the rack body, and nothing else. That's always been my interpretation and it's worked for me.

    That’s pretty much my interpretation, it’s a rack assembly aid, not a rack installation guide. The latter is defined by its flanges not by a relatively tiny hole.

    It's about centering the rack within the body rather than the body within the car. The rack being the geared bar and the body the cylinder that it's mounted in. So step one is the fit the body to the car via the mounts which fixes its location in the car. Step two is then to center the rack within the body. Then the track rods ends can be fitted and adjusted to get the wheels pointing straight ahead and the steering wheel fitted in the straight ahead position as well
