So earlier this week I put an end to the misery and bought a new handle assembly and lock barrel. The whole new assembly and lock was around £30, so not a mega expensive part.
This is how I fitted it - you will have to excuse the rusty rear door - it will be replaced at some point 😉
Its an easy job, so this is what you need:
- Phillips Screwdriver
- 10mm spanner or socket
- WD40 or similar
- Copper grease
Fitting the lock barrel
I bought a new lock barrel and fitting it into the handle assembly is as easy as pushing it into place!
Fitting the new door handle assembly
I had trouble undoing one of the bottom nuts. As it turned out, this was because of a stripped thread from a previous owner. The 2 top and 2 bottom bolts are held captive on a retainer plate as shown below
When removing the assembly be careful not to rip the gasket (I did!).
Fitting is the reverse of removal. As I didn't have a new retainer plate to replaced the stripped thread, I put in a couple of normal bolts.
You will need to check that the new lock assembly lines up with the striker plate on the body (it should do).If any adjustment is needed, its just a case of loosening 2 bolts on the striker plate and moving it into the required position.
It took me about 20 minutes to complete the job, and most of that time was trying to get the nut undone from the stripped thread!
