MAINTENANCE INFORMATION
If the valve plate assembly 6/11 is excessively worn it must be replaced.
Reassemble in reverse order, fitting new gaskets. When reassembling, lubricate every component
(except gaskets) with clean lubricating oil.
On reassembly, tighten the cylinder head screws to the correct torque loading.
3rd Stage Valves
Unscrew the tubing nut adaptors and detach cooler tubes from the cylinder head.
Unscrew and remove vavle retainer 7/15 and locking nut 7/14, together with seal 7/13.
Unscrew and remove caphead screws 7/12 and lift off cylinder head valves 7/11.
Remove valve 7/10 together with seals 7/9 and 7/8.
Carefully clean valves using soft scrapers, (eg. copper, wood, plastic) and petroleum (gasoline) to
remove carbon deposits and dirt.
Clean the cylinder face of 7/7 and clean cylinder head 7/11 thoroughly, removing all traces of
carbon buildup. Ensure that all mating surfaces are clean and smooth.
Clean the mating surface and cylinder bore of the cylinder 7/7and remove the rest of 7/7 above.
Ensure that no dust or dirt particles remain in the cylinder. Use compressed air to blow out if
necessary. If the valve 7/10 is excessively worn it must be replaced.
Seals 7/8, 7/9, 7/13 should always be replaced, to avoid premature leakage. When installing these
seals ensure that they are correctly located around the valves.
Reassemble in reverse order. When reassembling lubricate every component, (except gaskets but
including O-rings) with clean lubricating oil.
To reassemble, locate valve 7/10 into the cylinder head 7/11 with seals 7/8 and 7/9. Mate the
assembly with the cylinder 7/7. Replace the capscrews 7/12, turning 1/16
th
turn at a time in a
diagonal pattern. Tighten to the correct torque loading.
Replace locking nut 7/14 with seal 7/13 and tighten against the valve.
Replace lock-ring 7/15 and tighten.
Re-attach the cooler tubes.
