Issue 22 - Contains the front & rear engine blocks, block outer & inner, exhaust ports and screws; and has instructions for Stage 2 of the engine build: Adding the block to the base, attaching the front & rear blocks, and adding the exhaust ports.

Building the engine Stage 2

Take care when tightening the self-tapping screws, over tightening might strip the threads - stop tightening as soon as the parts are firmly fixed, or when the resistance in the screw driving increases.

Assembling the block on the base - Before you assemble the block onto the base, inset a type 'A' nut into each of the hexagonal sockets in the base - check that the nuts are located squarely in the sockets.

With the nuts in place, fit the block outer (part 2) onto the base so that its flanges slot between the walls of the channel; then holding the parts together, fit the hexagonal ends of the two posts on the block inner through the holes in the block outer, into the hexagonal holes in the engine base.
Then insert the long post of the upper assembly into the hole on the top of the inner block and push the parts together, ensure that the upper block seats properly.

Attaching the front and rear - The engine block rear is attached to the assembly with four screws fitted through holes in the rear block and into screwholes in the engine, carefully tighten these self-tapping screws (especially the lower screws which fit into elongated holes).

The engine block has two flanges that fit into slots on the engine and two holes that fit over the two pins on the engine. The engine block front is secured to the engine by two type 'A' screws inserted through the holes, take care not to overtighten.

Insert a type 'C' screw (from issue 21) into the central hole under the engine base, take care not to overtighten.

Adding the exhaust ports - The exhaust ports are identical, but make sure you fit them to the engine with the wider sides of the exhaust outlets uppermost, sparingly apply superglue to the side of the moulding which has three small pins, then press the port into place and repeat on the opposite side of the engine.

That's it for this issue, carefully store the assembly and any remaining parts.

Stage 2 of the gearbox assembly

Installing the gearbox filters - The two filters are slightly different, identify the left and right-hand filter, then locate into the corresponding two mounting holes in the gearbox site ensuring the pins are fully located in to the holes. Secure the filters in place with a self-tapping screw pass through the centre of the right-hand filter, take care not to overtighten the screw.

Attaching the gearbox top - Test fit the gearbox top onto the gearbox, check the contact points for gluing and that the two tabs at the wide end fit over the tabs on the gearbox.
Carefully apply a little ABS glue to the contact points and fit the top, then secure the top with masking tape until the glue has set.

Adding the lower suspension arm stays - Fit the left lower suspension arm stay into the left gearbox housing so that the two pins fit into the holes, then insert a 'D' type screw and tighten to about half way in.
Repeat the process for the opposite side.

That's it for this issue, carefully store the assembly and any remaining parts.
