5.2 ADJUSTMENT/TEST
5.2.1 NOSE GEAR
Adjustment of actuator stroke is provided at the ends of the piston rods.
The length of the nose gear rod is adjusted such that the over-center knuckle (brass)
rollers just bottom out on the down side and the piston just bottoms out on the mounting
flange.
The up stops nests in the up-stop pin. See figure 5.6 for location and assembly.
Nose gear proximity switches are located on clips that are mounted on the outer
cylinder body, one on each end. The most forward switch is for the gear down lights
and most aft is for the gear up position lights. Set the proximity switch mounting clip
along outer cylinder body to a position such that the light goes out when the over-center
track is about ¼ inch from bottomed position while traveling in the up direction. Lights
should come on about 1/8 inch from the bottomed position while traveling in the down
direction.
The cylinder piston has a magnet that will activate the proximity switches.
5.2.2 NOSE BOX TRACK WEAR
Due the wear over time the roller/slide block places on the track as the gear are
retracted, the block needs to be measured for the amount of wear. The tolerance for
wear is .050 inches. If the wear is, or is less than the limit, it can still be used. If the wear
in the track is greater than .050 inches, the block must be replaced. This check is to be
done every 200 hours and is part of the maintenance checklist.
On the 8000 Series Floats Gear Track P/N 8A07337 (-003 LT -004 RT)
5.2.3 SERVICE – MAIN GEAR RETRACTION SYSTEM
As explained in Section 5.0, retraction involves the main gear carriage moving back and
forth along the slide tube. The locking mechanism also moves a small amount in
service, enabling the locking hooks to hook and release as the gear locks in the up or
down position. Consequently, the slide tube and the main gear ram must stay lubricated
despite varying operating circumstances in order to work as intended.
Greasing might not be necessary, depending on operations, but these areas should be
inspected visually at least every 25 hours for cleanliness and lubrication.
The slide tube, gear locking ram and main carriage can be accessed at various points of
operation via the top deck panels or via the main wheel well with the tire off.
Recommended grease is HCF Grease, P/N 605 available from our parts department.
Care should be taken as with all aviation maintenance not to mix different types of
greases, especially in critical areas like this. Grease needs to be applied directly along
