Looking for S4 Door Latch assy

PostPost by: elanner » Tue Jul 16, 2019 8:16 pm

Does anybody know where I could get a pair of S4/Sprint door latches? I haven't been able to track any down.

Lotus part numbers:
036B6177 - Lock Assembly, LH
036B6178 - Lock Assembly, RH

Right now I'm looking for a left hand latch, although no doubt I'll need a right hand one when the time comes. I'm trying to make my door locks work properly.....

The picture below is for a Mini, so not quite right, but shows what I mean....

As I understand it the S4/Sprint door locks are from British Leyland door locks or latches as used on the rear doors of Austin 3 litre, Maxi, Austin Morris & Wolseley 1800 / 2200. They do appear from time to time but don't see any out there at the moment.

Here is a picture of mine. I'm in the process of cleaning them up. They are more squared off than the mini one you showed.

Yup - that's them! Anybody got one or a pair languishing in a dusty corner?

The internals may be the same?
If you have originals perhaps you can renovate?

The ones I have work fine as door latches but, so I've discovered, are missing the lever that the exterior-key-to-latch rod connects to. I've no idea why. Could they be from an S3 - where, I assume, the key operates on the handle rather than the latch?

I thought it was just a case of missing rods (btw, Sue Miller stocks these rods). My plan was to fit the rods during my current attempt to fiddle with the hinges and improve the door fit (ha - who am I kidding?).

Anyway, if I took them apart I'd still be missing the lever. Can they be non-destructively disassembled?

If anybody has a photo of the rear of the latch please post or send me via PM. I'm curious to know what it's supposed to look like.

Also, thanks to a forum member who PMed me to say that he may have a pair of latches. This forum is amazing.

There are several photos in the gallery here.
Also a few threads on repair-refurb.
It's sometimes easier to search in Google and come back in.

Thanks! I forgot about gallery search. So my latches are missing the arm at the top right with the lock rod..... :-(

'thanks to a forum member who PMed me to say that he may have a pair of latches'

If the forum member is unable to help Nick, I am pretty sure that I have a pair of new old stock latches that I would part with'
