g) Mounting the car body retainer

An assembly kit with fixing elements is included in the delivery. These

elements allow for an individual adjustment onto all car bodies.

The set includes:

4 car body bolts (1)

2 supports for the car body bolts (2)

2 mountings for the car body supports (3)

12 washers (4)

1 set of screws (5)

Assembling the supports of the body

• Stick the car body distancer bolts into the support. The end with the hole for the body splint must be placed on the same side respectively.

• Slightly fix the distancer bolts in the support with the short screws.

• Stick one washer each on the distancer bolts.

Attaching the car body support on the front and rear:

• Attach the carriers for the car body support with the edge (plane side up) to the

differential box and screw them tight.

• Screw the car body distancer bolts tight with the support on the carrier.

• Adjust the height of the bolts to the car body shape by moving in the support of the

body and fasten them by tightening the screws ( see image on the right). If necessary,

adjust the position of the support on the mounting.

• Apply coloured chalk or slow-drying paint on the tip of the car body retainer and

place the car body as exact as possible on the chassis.

• Remove the car body again and drill holes into the car body at the places marked

with paint (chalk) for the car body support. Use a special car body drill if possible.

• Define the position of the antenna tube on the car body and also drill a hole for the

antenna here.

• If necessary, effect cut-outs for the cable pull starter, the tank shutter and the cooling

head.

h) Check alignment and tooth backlash of the drive

The engine transmits its power via the pinion on the clutch bell to the main pinion. Both rotary axes, i.e. the crank shaft, engine side, and the axis of the drive

section to the front and rear axis, must be aligned exactly parallel to each other. This prevents tensions in the drive section, premature wear of the pinions and

bearing journals as well as loss of power.

The parallel alignment of crankshaft and drive section has to be checked every time before using the vehicle and if necessary it has to be

readjusted!

When the alignment is in parallel, the pinion on the clutch bell and the main pinion will

run smoothly. If there is too much tolerance this will destroy the toothed wheels in the

long run, too little tolerance destroys the bearing in clutch and engine.

Checking the tooth backlash

• Put a thin paper slip between the pinion on the clutch bell and the main pinion in the

drive section.

• Turn gears by hand

• The paper strips must not rip apart when the wheels turn!
