Reassemble rear end
6.13 Refit sliding blades (6) in their slots after lightly smearing with oil and removing any high spots with fine
emery cloth. Ensure the blades are orientated correctly in their slots.
6.14 Position the bearing seal (40) into position in the coverplate (3) ensuring that the tension spring is facing
the rotor for blowers and natural gas compressors and away from the rotor for vacuum pumps.
6.15 Press the outer race of roller bearing (18) into position in the coverplate (3).
6.16 Fit new o-ring (20) into the coverplate groove. If coverplate gasket (54) has been replaced, it is essential
that they are the same thickness as the originals, otherwise internal clearances will be affected and could
cause serious damage. Lightly smear the gasket with oil before replacing.
6.17 Place rear coverplate assembly onto cylinder (1) via location dowels and bolt with six screws (43) and with
coverplate gaskets (54) in place.
6.18 The whole bearing assembly can be locked onto the shaft with the bearing retaining washer (23) and the
circlip (37).
6.19 Press the shaft seal (22) into the end cap (4) with the tension spring facing the rotor.
6.20 The end cap (4) can now be fitted with the gasket (53) and any appropriate shims.
6.21 Position fan (15) on the shaft, with the set screw. Refit fancowl (16) onto supports with screws (44).
Check that the shaft rotates freely by hand before refitting lubrication system.
6.20 Reposition support plate (8) complete with oil pump assembly and tighten with clamp screw (45). Refit
drive pulley (28) and timing belt (30). Prime oil pipes before use.
