Gearbox bearing

[Kilroy]

Howdy all.

Does anyone know if it is possible to buy a new first motion shaft bearing for the 1800 gearbox.?
#104433
This is the very front bearing and it has a circlip groove around the outside.
I have stripped a gearbox which I thought had a noisy layshaft bearing - but the only bearing that seems bad is the front one.

I have seen a bearing kit sold by "Autogear" on eBay - but it is quite expensive having all the bearings,
layshaft and some other bits. All I need is the bearing.

I hope...

Cheers.

Don't panic.!

Found one at Rimmer Bros.

Cheers.

Hi kilroy,
Scott here with the 74 marina estate from Belfast.
Thanks for your help again, will try drop off that gearbox next time im over your way.
Kind regards Scott

[Kilroy]

Not talking to myself - there's just an echo in here...


Great Scott Scott.!
Assume that you are happily driving about in your estate then.?
Hope to be doing the same as soon as my screen goes in.
Actually - I should be doing it myself - but will watch carefully for any cool tricks then do any others myself.

Are you interested in attending any Morris related events.?

Cheers.

If you have a Triumph supplier in NZ ask for a Triumph Spitfire 1500 or 4 speed TR7 bearing, it's the same bearing.

Nearly driving happily around. ...just failed wof on the steering rack.
Im trying to get this fixed asap, then i would be keen on attending any morris related events. I did meet all the morris guys at the chch swap meet, nice bunch of fellas.

[Kilroy]

It will be the bush on the left side of the rack.

I have a new bush here if you want...

I do overhaul them if you get stuck.

Cheers.

I was told that I need to remove the gearbox to get at the bush/rack
Is this right?

[Kilroy]

Absolutely not.

The steering rack can be removed from under the right mudguard after releasing the tie rods from the rod ends, removing the steering column and releasing the two u bolts that hold it to the firewall.

If you can drop the car here for a day I will do the job for you for bugger all... (technical term..)

Hopefully the gaiters are up for another tour of duty.

The only Truimph dealers we have are those selling motorbikes.

[Kilroy]

Actually - there are some Triumph parts stockists, and I use them a fair bit.

By the way - I have a spare window winder handle or two if you still need...

Cheers mate.

[Kilroy]

Hmmm.

Actually.

Before I dig a deeper hole - can anyone conform that the Mk1 steering rack uses the same bush as the later versions.?

Thanks.

[MarinaCoupe]

Yes Kilroy. The early ones are a white nylon-y substance, the later ones are black and seem to be slightly harder wearing. They are all the same dimensions though.

I reckon there's a good chance that an NZ bearing supplier will have one on the shelf.
