Hi Guys,
(So while the engine and I’ve got the time), I’m tackling the bumpy steering.
I’ve been following the manual as closely as I can. And I'm assuming I'll find a worn felt or polymer bushing when I get that far.
I’ve got the rack off the car, removed the tie-rod ends and the boots and removed the pinion etc.
I’m a bit stuck at the inner tie rods.
The (Orange) BMC manual states as below.
“Use the Service Tools 18G 1030 to unlock and dismantle
the steering rack ball joints
Punch the indentations in the locknut clear of the slots
in the ball housing. Slacken back the locknut and unscrew
the housing to release the tie-rod, ball seat and seat tension…”
Is this the right sequence – should I be prizing up the indents before I try to unscrew the lock nuts?
And in the event that I have nothing like the Service Tools mentioned - is there something better than grips to use?
I also had a look at John Twist’s Youtube video on MGB inner tie-rods, (he refers to the special tools, but then attacks it with FIRST a punch to prize open the tabs on the lock-nuts and THEN twists it off with a pair of grips.)
Your advice is always appreciated! Paddy

Tap up the indents with a skinny punch. I found a pointed one got things moving by being able to dig under the indents. A "C" spanner is the correct weapon to get the caps moving.

Agreed. I followed John Twist video. I ground an old screwdriver to the right width then a 45 degree (roughly) one sided wedge. Worked a treat. Got a new bush from Sweden after finding a terrible knock when going over bumps. Transformed the steering.

Thanks so much for all the advice! Now that link didn't want to open - came up with Bad Link warnings (they're going to steal all your data!) Did you have the name of that company - so I can google separately? (I'm hopeful the local man here will have the bush.) On the tab that you were bending back was that the one in pics TAB 1 or TAB 2 or both? Best regards Paddy

Try www.mlproduktservice.com/morris-1800.html# or search 27H7547 . The preload on the track rods is set by locking the inner cap to the outer one, so releasing the outer indent will release the outer cap. To re-set the preload when reassembling you will almost certainly have to move the inner cap, so you'll need to release that as well. Chris.

This is possibly the clearest explanation of how to adjust the inner ball joints and rack shimming I have ever seen - it starts around 19 minutes into the video. RackDavid

Very clear and informative.
It's worth noting that a number of rack components are shared with the MGB one, as they were both made by Cam Gears.
Track rod - 17H 8713 Thrust pad - 17H 6571 Thrust pad spring - 17H6290 Track rod end - 18G 8043 TRE dust boot - 17H 3501 Rack gaiter - 13H 1291
I have the rack bush available if required.
