Trying to get rid of the last of my Roadster spares. All that's left now is an unused 4.11:1 diff for the 1.3 engined car and a steering rack of unknown condition but doesn't look too bad. Free to anyone who wants to collect them.

Re: Marina Roadster Spares
I have to admit that I don't know the difference between the Mk1 and Mk2. Some time ago I replaced the rack on my 1971 Marina based Roadster without realising that there were two variants. How can I tell the difference?

for those who want to know the differences, somewhat inevitably, a document is available on Keepandshare. It’s free to access. I would rather it stand alone as most relevant answers are there too.
As I intimated, it’s all down to the rack mounting difference and a change in length which is very odd considering that the chassis jigs did not change from one to the other. Very odd as the swivels at each end are identical.
Either way, given that your rack is of indeterminate pedigree, it’s worth changing out the ubiquitous bush as a normal matter of good practice.Last edited by stevejgreen; 29-08-20, 08:52 AM.

Re: Steering Rack
A quick way of telling is the MK2 rack has 2 different sized ends on it. The O/S is 35mm and the N/S is 29mm, whereas the MK1 is 29mm on both sides.

Do you have part numbers for the mounts, I’m pretty sure they would have been imperial sizes and not metric!

Re: Marina Roadster Spares
There 2 other differences the MK1 rack is 40.0" in length and the MK2 is 40.25" and the MK1 doesn't have the filler hole in the centre of the rack tube.
Part numbers for fixtures on the MK2 ( mine is a MK2 so these are the only ones I have ) are:
Rubber Rack Mount Pinion end 21H6799
Rubber Rack Mount Support end 21H6800
2 x clamps FAM1120
2 x U-Bolts FAM1121
4 X Nuts LNZ205
4 x Washers WC108051

Re: Marina Roadster Spares
Mine does have the hole in the centre of the rack tube so I guess its a Mk2. There is a number stamped on the pinion body which is 49 86R.Attached Files

Re: Marina Roadster Spares
I am not too sure about the filler hole comment not being on mk1 racks.
I have a mk1 and it definitely has a filler hole. This certainly looks like a mk1 rack and has a filler hole.
In Adrians picture, post #5, it shows both a mk1 rack (fitted to the car) and a mk2 rack (resting on bonnet sides) and the both have filling holes.
Also, I was lead to believe that the hole doubled up as a way to centre the rack when fitting.Last edited by jon_cox; 27-08-20, 03:52 PM.Mk2 SWB Marina Roadster with a 1800 Fiat Twin Cam engine and 5 speed Abarth gearbox built in 1987

Re: Marina Roadster Spares
One of the downsides of this forum is that the search engine is lacking and that this thread is about Marina Roadster spares but has veered off rapidly after my question about the application of a steering rack. A search in five years time, however would you phrase it, would not necessarily find it.
My doc has been unedited since 2015, should it be updated with new ‘found’ data or is it still a reasonable source?
I would be happy to edit it If there are verified sources of information? Meanwhile it stays with 1166 downloads.
Carry on nit picking.Last edited by stevejgreen; 27-08-20, 05:50 PM.

Re: Marina Roadster Spares
I'm in the market for a working Mk1 rack if anyone has one going? Mine failed Mot as it had been stood a long while before I bought and steering was stiff. I thought if I topped up the oil and used it a while it would losen up but it spat the oil out of the drivers side.
