Hitchcocks Forum

Happy new year guys although slightly late. Been off the forum as work kids and all sorts of boring responsibilities however After a cold and wet few months I tucked my Model G up for winter , today was dry cold and sunny so decided to take her for a spin. Gloriously she ran. On my way home I heard a rattle clunk in the primary case , I believe the chain may be loose , question best wat to tighten as l have been told there is a tensioner however can't seem to locate it.

Regards Reds

It would take an age to explain it.. Remove the primary cover, all will become clear. The tensioner is an adjustable pad under the chain.

I think you will find that on the model G the chain is adjusted by moving the gearbox backwards and forward?.

Moving the gearbox backwards and forward? If that's the case, it's a step backwards.. but on the other hand, I don't have a model G...

I'm off to the shed...

As I understand it the model G was made from around 1946 to 1955, at this time almost every bike made had a separate gearbox and it was mounted with one pivot bolt and one other bolt which was through a slotted hole in the mounting plates and the box rocked backwards and forwards to adjust the chain when the bolts where loosened.

The later Enfields had the gearbox bolted solidly to the back of the crankcase which allowed the tensioner system to be used this is also the case on unit construction engines.

You can hardy call it a step back when it was made earlier, perhaps the later system could be called a step forward, hopefully Reds didn't strip his bike down looking for a spring tensioner.
