Repairing Mortice and Yale Lock

Postby beanie » 24 Apr 2013 11:56

Hello :-)

I'm attempting to get hold of a Yale Receiver/Striker for the lock bolt to go into - I have uploaded a picture here http://www.garethgroup.com/lock/yale.jpg :-) Any tips on where to get the right size and also how to fit it since a previous one has been forced out (before I moved in).

Also, the mortice lock was very stiff so rather stupidly I took it part to oil it and the whole thing fell apart - Any ideas how to put this back together please: http://www.garethgroup.com/lock/mortice.jpg

Thanks and Kind Regards,

Beanie.

The Yale nightlatch is a Yale 84 narrow stile lock, which can be found pretty cheaply at most DIY sheds. Unless you find a friendly lockie who has a bin full of spare parts you are unlikely to find the strike on it's own.

The mortise is a Wickes model, which means it's a rebranded era, from the look of it either a viscount or a pro-fit. The levers should have a number stamped on them, and they locate on a spigot in the case directly behind the bolt. The order is important, trial and error should get you there, alternatively post a pic of the key and lever numbers and I can tell you the correct order. The silver alloy part is the curtain, and this locates in the keyhole, with the tall side facing up. You'll have to insert this before the levers. The black bit is the curtain spring, which locates around the lower fixing screw stud, with the curved face towards the fore end of the lock, and flat face sitting against the curtain at about 45 degrees.

Hello, thanks ever so much for taking the time to reply :-)

Having looked at the mortise, you of course are absolutely right: it is an era, not sure about what kind it is after establishing that, the side frame or whatever you call it - this - http://www.garethgroup.com/lock/lockframe.jpg

says:

Era 5 lever
Made in England
Certified to British Standard
RS3621 1998

Other than that here are some more pictures:

http://www.garethgroup.com/lock/lockbuilt.jpg (this is how I have put it together so far, not sure if this is right?
http://www.garethgroup.com/lock/lockclosed.jpg
http://www.garethgroup.com/lock/lockside.jpg
http://www.garethgroup.com/lock/key.jpg (sadly no numbers or letters on either side)

Lever Numbers:

1,2,3,4,4

(i heard somewhere the first and third levers should be the same number - is this true?

Please could you let me know if I built the lock properly or where I was going wrong?

Thanks and Kind Regards,

Beanie.

You still need to insert the curtain spring, this prevents the curtain from turning out of alignment, which can prevent getting the key in. The spring sits around the lower case screw, if you look at the spring, and the gap available you should be able to see how it goes in.

To suit your key, place the levers into the case in this order: 4 1 4 3 2. As you can see, this tallys with what you've been told about 1st and 3rd lever being the same, which is indeed correct in the vast majority of 5 lever locks which have keyholes on both sides.

If this works, it might be worth editing your post to remove the key photo and bitting info, though it is highly unlikely anyone will use the info for mischief.

Good luck.
