My Sad Sprockets

[Lynn Eades]

Could "Local Guy" and "The Bedford Boys" please add a name to their profile. It is nice to be able to use a name. Most of us on here have one

We must all remember that the drive train on Carriers goes back a long way and has a war at the end of it! The evolution of parts both reflects design improvements and production compromises. I suspect that the sprocket shown is an early version used until someone had the bright idea to simplify the manufacturing cost and time. The loyd version on mine and a 1941 dated example I´ve seen are flat, just like Martyns photos. All my sprockets are shot, worn to within an inch of their life by the Belgians post war. I too need a NOS example to get the profile from as I need to get four made. Will anyone in the midlands lend me one or a .dwg for the lazer cutting chap? I know Martyn hasn´t got one as his are bolted to the UC

The simplified sprocket doesn't positivly guide the track on a UC, but for some reason when Loyd used the standard sprocket they added the guide plates to run against the outside track horn as discused earlier in the thread, the other horn on the track runs an a deep groove cast into the drum. The sprocket is attached to the drum by bolts and special curved steel plates on the back side of the drum sprocket flange, thus on a Loyd the sprockets are bolted from the front and there are no nuts, the curved plates are tapped instead.

PS. Loyd brake drum is with the pattern maker now...worn sprocket is on the workshop floor, came off quite easly once Martyn had used his heavy duty socket set to split the drum from the hub! (thanks for the help)

Those sprockets would not have been original to your carrier. It has probably worn out both track and sprockets,

[RichardT10829]

i must agreee with Lynn. i have been through the parts and service books and there is no mention of the regular sprockets being superseeded by these... most likely they have come from the loyd or perhaps a vickers light tank ? / T16.....not a universal carrier though.....of course i am known for being incorrect...

[Lynn Eades]

There would be a lot more work and expense to produce them. Vickers light tank is a good thought.

Guys,
I meant to take the paint off of the part numbers this last weekend so I could post them. There are definitely some stamped numbers on them. I will take some pics tonight. Lynn, I think your right about my worn out track but my lack of experience keeps me from telling if too warn out. Anyway I will probably "Run What I Brung" at the expense of the next set of sprockets. Actually you can tell by counting track links cant you? I forgot about that.
