Installation 7 - O.S. engine MAX-12CV Series Owner's Instruction Manual

ENGINE INSTALLATION
Make sure that the vehicle's engine mounting
surfaces are level and in the same plane. Poor
installation may cause distortion of the
crankcase, bearings, etc., resulting in erratic
running and loss of performance.
The recommended screws for securing the
engine are 3mm or 4-40 steel Allen hexagon
socket type.
If existing holes in the engine mount do not align
perfectly with engine mounting lugs, enlarge
them slightly with a needle-file so that screws
enter vertically.
Chassis
Chamfer inside edges of bearers.
Avoid forcing the screws. Secure with locknuts.
If the bottom of the recoil starter housing would
otherwise touch the car chassis, fit the engine
mount spacers (supplied) between the engine's
mounting lugs and the engine mount. Use the
M3x15 screws provided. With some vehicles, it
may be necessary to make minor trimming
modifications to chassis or body when fitting the
engine.
NOTE:
Where spacers are supplied joined in pairs
(see sketch) separate them as shown.
Either face may be placed downwards.
