Title: 6HP JAP CLUTCH
Post by: TONY REGAN on June 15, 2014, 03:39:52 PM
After the advice I got with ignition on this motor I wonder has anyone has dealings with the all-metal clutch. Mostly straightforward but in the pressureplate cover there are 3 holes for securing the drum and one mystery hole closer to the centre taped 3/8"cei I think,what's it for ?Thanks Tony

What year is this engine again ?
Clutches were mostly only invented when gearboxes appeared, in the teens mostly,
so is it a later clutch that someone has adapted ?

A pic could be useful...

Definately an option for cyclecars in those years and drives a 2-speed Chater-Lea gearbox,then to countershaft and 2-belts to rear wheels.

Hi Tony,

If the clutch is multi-plate and all metal, it probably runs oil inside. My 1910 FN has a clutch like this, and theoretically you undo a screw and fill it with oil. I usually give it a squirt before I ride it, but most is on my boots by the end of the run. Perhaps the thread hole in your clutch is just for oiling?

Anyone got pics of pre 1910 cyclecars or tricars, particularly engine/clutch/gearbox setup ?

Thank you Cardan,that would solve the mystery of the hole  and why there is remains of a gasket in the drum.So I imagine the level with that hole set at it's lowest position and a light oil.
Yes R' that's the sort of arrangement of clutchdrum and release mechanism. This one has it's stirrup attached to a post and acts in a horizontal plane. Some bits missing between that and a pedal in the vertical,so a bit of recreating to do as these were mostly one-off's I think unlike the combination. Thanks

Hi Tony,

What a lovely beast!

I have an interest in such things, but I'm not expert. A friend is a real cycle car tragic, and he reports that all the suspension parts and axles are "pure Chater Lea". Any chance of a few more photos? Do you know who assembled the car?

Cheers

Leon
