08603 FG Viscous Locking Differential Kit for FG Models

suitable for all 1:5 scale models, 1:6 Race Trucks, Buggies, Monster Trucks

and Formula 1 models.

The flange bushes 8602/2, roller bearing 8602/1 as well as the shaft sealing rings 8600/6

and the ball bearings 8493 were professionally mounted on the alloy differential housings

A/B by FG.

Now assemble the steel gearwheel 48 or 50 teeth on the alloy differential housing A, for Formula

1 models use the differential gear disk 42 teeth.

Check internal and external fins on burrs, remove them if necessary with coated abrasives.

Make sure you don’t twist the fins.

Now mount the fin package as shown on the picture: Attach a differential bevel gearwheel

with square on a differential bevel wheel axle. Then fix on the square in this order: 1x internal

fin, 1x o-ring 14x1,5, 1x external fin, 1x internal fin, 1x o-ring 14x1,5, 1x external fin, 1x

internal fin and last 1x external fin. Lubricate the shim rings 8600/13 with a little bit of grease

and lay them on the flange bush 8602/2 in the diff. housing. Insert the complete package

now as shown on the picture in the differential housing A. Then press the differential bevel

gearwheel together with the fin package with a screw driver against the housing and pull

out the differential axle carefully. Push both bronze bushes 8600/8 from the inside outwards

into the borings of the differential housing. Deposit the differential bevel gearwheels B in the

housing and impress the diff. bevel wheel axle 6068.
