90/Def door help

D.G.F.S. · May 28, 2018

Evening all, need some advice regarding door locks / fitting. I’ve just bought a pair of early 90/110 doors from the bay with lift up handles and wind up windows (with single outside handle). I think the lock part number is MUC2290. Anyway, the locks seem to be in good condition all be it needing new barrels, what I need to know is what striker goes with this type of lock and does it need drilling to the pillar with bigger/extended holes for adjustment? Also if anyone has this type of door/striker any pics would be appreciated. Thanks all,
Ben.

I don't have any pics but from the parts catalogue:
Fig1 & 2 are the strikers for LU & PB handled doors; I have an '85 build ('88 reg) 90 with LU door handles but the later strikers, so I guess they're interchangeable?

For MUC22290 you need barrel MUC4146. The lock assemblies themselves (MUC2290/91 and MUC6979/80) are NLA.

The early barrels MUC4146 have grooves for two ball bearings (5mm; 13/64'') which are needed to secure the barrel in the holder, they are a right PITA, lots of grease helps hold them in place as you insert the barrel; thread about LU locks here: https://www.landyzone.co.uk/land-rover/fixed-early-90-door-lock-barrel-replacement-problem.320095/

Capo, thank you for such a detailed reply, really helps me out. So your saying is the MUC2290 mechanisms should/do work with the later 90/defender striker? That’s good to hear as I’ve just googled the prices of the striker MUC2959 and they’re just shy of £50 ea with vat

You are welcome

The landy is currently undergoing an engine transplant so I can't access it but I know the strikers are the later plastic covered triangle spacer and enclosed catch

rather than the early mushroom knob

, and the lock assemblies are definitely MUC2920/21. You'll need th support bracket etc. MWC1736

for the later striker.
I see that both types are applicable from DVAD7AA270227, DVAC7AA270484 & DVAV7AA271214 so should match up, maybe with some fettling?
For what it's worth, I think the LUH doors look better than the PB, hence my efforts to fix the locks which were knackered on purchase

Well my pb doors are past it, I think the luh ones look better too, plus I feel they’re more secure hence why I was happy obtaining the luh ones instead of pb. As for the strengthening bracket, I can make something that'll do. How come you’re having a new engine?

Here you go.
Lift up are positioned in a different place as you can see the unpainted area

Thanks for the pics Phill, I will try the doors using my current pb striker and with your pics at least I know what position I would have to attach the earlier striker if needs be. Cheers Ben

That is odd as I haven't got the 'trouser belt loop snatcher' but the triangle shaped striker and bracket yet the latches are the early type with LUH

Let us know how it all works out

Oh good. Glad I'm not alone

Was the change something to do with antiburst locks?

yes i think so, it latches '2 stage' - like a half latch, then a full latch if you see what i mean
