4-5 Checking Mode after Reassembling Deck Mechanism
After disassembling the deck mechanism, check the positions of the following gears when
reassembling it: If the positions of gears drift, the deck mechanism will not operate normally.
Turn the cam gear with the L/D motor assembly removed, and make sure that loading and
unloading are performed normally.
1) Make sure that hole (A’) in chassis on the surface of deck mechanism is aligned with hole (A) in
cam gear: If they are not aligned, remove the L/D motor assembly, and then turn the cam gear
until the holes are aligned.
2) Make sure that the small hole in cam gear on the back of deck mechanism is aligned with hole
(B) in drive gear: If they are not aligned, remove the drive gear, align their positions, and then
reassemble the gears.
