how to install a slipperclutch in a Sand Scorcher

Some time ago I promised to take some pictures and make a 'how to' of the slipperclutch in my Sand Scorcher.

You only need a DF-03 slipperclutch, a DF-03 78T spur gear, a 23 T pinion gear, the original main shaft of the Sand Scorcher and a hollow brass - aluminium tube with a inner diameter of 5 mm. You don’t need the main shaft included in the slipperclutch set.

First thing to do is to make two flat sides on the main shaft, about 18 mm long, until it has a diameter of 4 mm. Now put a little 0,3 mm shim , the ball bearing and a aluminium hollow tube (5 mm inner diameter and about 6,2 mm long) on the main shaft.

Assamble the gear case and install the motor. Now you can fit the pressure disks, slippersheets and a 78 T spur gear. For the pinion gear I used a 23 T steel one.

The last thing is to attach the adjustable slipper spring. The screw is 15,5 mm long (the threaded part). Put a small shim on the screw, the springretainer and then the slipper spring. Now install it on the main shaft. This way you can still adjust the slipperclutch.

You must adapt the plastic gear cover otherwise it wil not fit.

Just look at the pictures so you can see how i did it.
