Repairing a broken cam in a Millenco gearbox

Having Problems Knowing How To Replace Your Cams? No Worries! See Our Easy-To-Follow Instructions!


The Millenco 117/86 multipoint lock is a very popular and strong locking mechanism that is extremely durable and built with years of usage, unfortunately, the cam in the Millenco multipoint lock can sometimes break. When the handle is turned, the cam that moves the lock in and out of position can shear off or shatter. This will result in the handle no longer being able to turn the lock.

We supply replacement Millenco 117/86mm PZ multipoint lock cams, meaning the whole lock doesn't need replacing if the cam breaks. 

WindowParts Ltd sell the replacement cams for just £7.20 plus vat, click HERE to goto the product page.

This step-by-step tutorial video below shows you how to swap the broken cam and replace it with the new cam. WindowParts make replacement cams to a very high specification and very high quality meaning they should last longer than the original part.
