Car having MOT today, passed but advisory that the steering rack is rubbing on the bottom of the radiator. ( original factory rad). Despite getting soaked I crawled under the car & removed the bottom rad supports. I could find no reason why the rad had moved. No buckling of the supports & the rubber bushes looked fine. I am now wondering if it has been rubbing since build 2011! (A 4/4)
The rub is central where the two centre bushes are on the track rods. At the moment am not sure how I am going to correct the issue.

Just a thought but could you put some washers under the lower rad support brackets where they clamp to the ali rack mounts to move the rad forward a little? You might need slightly longer bolts through the rack mounts though.

Thanks Rog
My parts book gives the bolts as MGB0382 anyone know what size these equate to, so I can try and source some longer ones. Due some bruised ribs I can not get under the car to remove one and look at it.
Thanks in advance

Had a quick look whilst loitering under the car today. Can’t tell you which thread but they look like 5/16” dia x 3.5” long bolts. If you use new locknuts the thread type is up to you but definitely use high tensile bolts….

The car has now been looked at by professionals (so much easier on a ramp) My car now has 40000 on it & it would seem that the constant movement of the steering rods has exerted a forward pressure on the "Z" mounting bracket (MSR0287). The bracket has bent forward causing the two centre steering rod bolts to rub on the bottom of the radiator. Luckily the bottom of the standard radiator has a steel strip which on mine now has quite a gouge in it. Failure of this bracket would be catastrophic, so a new one on order, but a watch point for the future. Interestingly we took a picture of the same area on a +4. Whilst the steering rods were not actually touching the rad it was very very close.

Good watch point. Amazing that those brackets are bending. You wouldn’t want a fatigue failure there!

It seems having read the GoMog article that the bent bracket that attaches track rods to R & P steering (MSR0287), if cold bent in manufacture, will have ever reducing strength if bent further. If I understand correctly this is what has happened in your case and only come to light due to radiator damage scared

Interesting to note the "Z" plate whilst shown, is not separately identified in current 2014 onwards Classic parts book, although there is a suggestion it's still the same part used since intro of R & P steering confused2

Richard, yes that is why on discussion with the mechanic we have decided to order a new one & replace the fitted one which has been bent back.
Somehow my “Z” bracket had bent forward & we could only surmise that it is the action of the track rods that could do it. As you say without the MOT chap noticing the rub on the radiator I would have never known. Does make me wonder if the author of the go mog article, steering arms/ track rods had been flexing the bracket, not so much that contact with the rad had occurred. Having said that, if these brackets had been regularly failing the community would definitely know about it. I certainly will be interested if any TM ers find their racks are touching the rad. I guess in my case the bracket has become a service item.

Ice Pack, I damaged my Z bracket while swinging the front of my car round in the garage, while on my trolley jack, as the cross bar slipped off the jack`s pad and bent the Z plate (1984 version)... Duh!

remembering the link I posted from GoMoG, I did not want to straighten it and ordered a replacement from Melvyn who supplied the later version... My guess is that if anyone is as careless as I was while jacking the bracket can easily be bent...

I note that Lorne designed a different bracket made out of SS, with reinforcement plates welded on each end I suspect I note he welded the nuts to the bracket as the reinforcement probably made spanner access difficult..?
