screwed together tightly again. Finally the swash anti-rotation device D33 is
fixed with 2 distance bush swash blades D32 and 2 hex screws M3x30 D337, using
also a lot of Loctite. Now remove the swash leveller to check the free movement
of the elevator swash bush in the antirotation device. For this it is necessary
to disconnect the servo arm. If the bush has difficulties running fully downward
in the anti-rotation device, both screws of the anti-rotation device have to be
tightened up. A slight clearance should be there, to assure a free-movement
control.
Bag 9: Mainrotor (Step 27-30)
27. First the two plastic bushes D483 are fitted in the mainrotor hub D482.
The feathering spindle D235 is inserted next and centered.
The rotor head cap 580 is installed with x4 hex lens bolts M3x6 D199. From
each side one after another will be slid on: a 0.5mm shim washer 757, a
10x19x5 radial ball bearing D238, a blade grip mounting bush D239, a thrust
bearing D237, a shim washer 10x16x0.2 033 and again another radial ball
bearing D238. Note that the shim of the thrust bearing with the larger inner
diameter (10.2mm) must be mounted first and the other one (10.0mm) is
mounted outsides. If you have no caliper to measure that you can simply put
both shims onto the shaft. The shim that can be tilted more is the inner
shim.
Each side is secured with a hexagon socket bolt M6x14 D234 and shim D242
each side – the spindle thread and the bolt should be degreased before
assembly and coated with Loctite as per usual practice. The inner thrust
bearing race, which sits loosely on the spindle shaft and the bearing cage
open side facing inwards, are lubricated slightly with grease. The outer
thrust bearing race is a tighter fit on the spindle. The unit will now be
slightly tightened with x2 5mm hex cross handle wrenches. Before the M6
screws are finally tightened with Loctite check the free running of the ball
bearings but without any endplay. If this is not the case add or remove
washers. It is allowed to get a washer difference of 0.1mm between both
sides. No vibration will occur from that. After tightening the feathering
spindle, turn the spindle about one revolution to equalise tension across
the rotor head. Then the unit should be cleaned of grease and each bearing
assembly rolled over a flat surface, so all components are aligned
concentrically. This will assist sliding-on of the blade grips D240.
28. Warm the blade grips D240 with a heat gun or in the oven and push them
on, holding with an oven-cloth to avoid burned fingers(!) so that they are
aligned to the bolt holes. With a 2mm hex socket wrench, or similar, it is
possible to line-up the holes in the grips with the thread holes in the grip
holding spacer.
After cooling down, the blade grip arms D53 will be screwed on with a hex
bolt M3x8 D197 and a hex bolt M3x14 D198 (do not tighten too much yet). Put
x6 hex bolts M3x6 D199 in each of the free bore holes of the blade grips.
Then the blade grips are pulled forcefully outwards, and the gap to the
plastic bushes D483 checked for symmetry. If everything is consistent, all
hex screws will be tightened up. Finally the rotor head is checked for free
and even movement.
The two swash driver arms D65 are attached to the rotor hub with hex lens
bolts M3x10 989 with an intervening shim washer 3x6x0.3 D110. The other side
of the swash drivers are screwed together with two swash plate driver bushes
593, two hex lens screws M3x12 982, two ball joints 385 and two Philips
screws M2.5x12 507. Check the swash drivers for free-movement, rock slightly
if rough running, until the relevant ball bearing settles.
29. The rotor head push rods will be assembled out of 4 ball joints D72 and
turnbuckle-control rods 199b. The length over all is 61mm. Please note that
if the left-handed thread (with small groove) is to be placed on the upper
part of the grip, then later clockwise turning will lead to reduced angle of
pitch at the rotor blade. Now carefully screw in 2 ball-joint bolts M3x4 076
opposite to each other into the inside ring of the swash plate (do not
tighten too much!).
30. Then the 10mm bore of the main rotor hub is slightly oiled together with
the end of the main rotor shaft and the rotor head is pushed on without
