Proof of the pudding.

Old Sulzer likes his fruit vids more than I like my Xhamster, and that's saying something!!

I clean the dirty red grey cam shaft and grey cam switch holder with a good degreasing detergent and warm water and a small paint brush to get in the awkward places. The rest of the metal work I clean with Autosol. Once everything cleaned you can add a very small amount of grease into the gearbox aperture if required as they don't usually require attention. Now really just re-build the unit in reverse. make sure the cam switches are fully seated in their holder when securing their clamps. The bottom securing rod and nuts are adjustable by a few mm so if needed you can move the whole rack of switches either nearer to the cams or away to correct their operation

Yes, No problem. I will put up a post on the timer servicing.

Very nice, thanks a lot @Clo06 Thanks to @Playerfor the resources too, so good to get this emulated and preserved.

Once everything is apart you should have the unit looking like this in small and lager version shown. NOTE.... An important point to remember is the main timer control cam shaft with it's red and grey cams are all set in degrees of operation which is crucial to the running of the machine. you must ensure that none of them are altered or moved in any direction or the result will be cam switches being operated in the wrong order or not at all. normally these cams are tight fitted and do need some force to move them but still treat with caution. The red and grey cams are set together in degrees around the shaft to make dwells in the cam of which the roller of the cam switch will run in and back out only one time, in turn this will activate the cam switch. A single red cam does exactly the same but usually to operate a switch more than once during the game cycle.

Disconnect the motor from the gearbox by removing the spring clip across the back of the motor. the gearbox is held to the timer side plate by two small screws either side of gearbox but leave for now as it's still connected to the main timer cam shaft. Remove the far end plate away from motor by the three securing nuts on the rod clamps.pic 2 You can now remove the main cam shaft by releasing the hex nut securing it to the gearbox shaft.pic 3 disconnect the motor end plate via three locking nuts and disconnect the gearbox from the side plate by removing the two small screws. the grey cam switch holders can now be slid along and off the three securing rods.
