Is this the type of clutch you have?
Wingett or thwaites dumper, repair drum clutch
Black smoke don't mean it's broke, keep it flat out like a badger on a bypass

Or is it hydraulically driven and new oil filters or oil needed?

What happens when drive is lost, does something appear to slip or is it instant?

Gday and welcome to the forum janmik.
I domthave any diagrams or parts list but these machines have very basic electrics as it is usually only for the starter motor and charging system. This bei ng the case a basic charging system can be found using Google or YouTube. You possibly have an alternator which should have a built in regulator, a battery, an ignition switch and a starter motor. After that lights are also basic and easy to incorporate.
What problem/s do you have with the electrics?
Cheers Cobba

Hi Cobbadog, the translator mistranslated my sentence. The electrics are ok, I have a bad clutch and brakes. I need a diagram of the spare parts so I know how it should be assembled and what is missing.

Have you taken off/removed the brake drums for a look/inspection of the brakes?

Hi mate, have a look at my thread running now, Grumpy Dumpy. I have brake issues but mine is a Liner ROughrider dumpy. The brakes on mine are Girling brake system rod operated and very simple mechanical action. Standard 10" diameter so shoes are readily available. I have a broken return spring which I should be able to get one easily. I have to replace an axle oil seal which I will buy next trip to town.
To remove my brake drums I backed the brake adjusters off then used a slide hammer to remove the drum, they were tight to remove because they locate on the centre hub and the wheels studs have a shoulder that fit to as well. Hope this helps you.
Cheers Cobba
