Rootes75 18 Posted January 13 Share Posted January 13 (edited) So, I have been pondering for quite a while now about posting about my Commer. I haven't really got very far with its restoration due to work and lockdowns etc but things are moving slowly. I have posted before about the trouble we had getting her running, that took a long time and eventually we serviced or replaced pretty much all the electrical side and the fuel system. She now runs fine but we have trouble actually starting her sometimes, we find that the starter jams and we end up having to remove it to free her. Long story short, when the starter was out just before Christmas I noticed swarf in the bell housing, after carefully running a finger against the starter ring I found that many teeth were worn so I decided then even though its a big job we needed to strip and replace the starter ring. This in itself meant dropping the prop shaft, making a nice trolley to drop the gearbox / bell housing onto and removing all the cab floor to get access and then tend with bolts that had been in place for 70-80 years. You all know what I mean. So, below shows the starter ring on the flywheel, its actually welded in 3 equally spaced slots All looks fine there but take a look at the wear on the teeth below! We couldn't believe how awful the teeth are, its not restricted to one place but many sections around the ring. It made me very glad in the decision to strip and replace it. You will also notice that the starter ring does not sit flush all round the flywheel, it actually has bowed out between each of the welds!

I would think that starter ring has been changed before, because it is unusual to weld them in place, you normally heat them and shrink on. I wonder if it was the correct ring?

Rootes75 18 Posted January 13 Author Share Posted January 13 (edited) Yes, the ring should be heated and then let cool into place. We were very surprised to see the weld when we removed it. The weld could have been a wartime fix maybe? Edited January 13 by Rootes75 Quote Link to post Share on other sites
Rootes75 18 Posted Monday at 11:45 AM Author Share Posted Monday at 11:45 AM So, I contacted Speedy Spares last week to ask about getting a new Starter ring. I was asked if I could count the teeth as there are two types that would fit. The Commer Q4 has a ring with 146 teeth and the Starter pinion has 10 teeth. The Commer Q2 has a ring with 115 teeth and the Starter pinion has 9 teeth. Guess what, we counted the teeth yesterday and we have 146 teeth on the starter ring and 9 teeth on the starter pinion!?! So its a mix of the Q2 and Q4 and no wonder that she has a problem starting! I am lucky, they have a starter ring with 115 teeth in stock. Quote Link to post Share on other sites
Richard Farrant 42 Posted Monday at 12:18 PM Share Posted Monday at 12:18 PM I did wonder at first glance if it was a mismatch of teeth numbers when you first posted it, due to the damage to the teeth. Quote Link to post Share on other sites
Rootes75 18 Posted Monday at 12:49 PM Author Share Posted Monday at 12:49 PM It does make sense now Richard. But, upon taking it apart you could see this was a very old fix so this was done a long time ago, I would imagine previous owners must have had trouble too. Quote Link to post Share on other sites
