AIRSTREAM 360 XC LAND YACHT OWNERS MANUAL
Instructions for removing the motor assembly (part #9501) from the step frame and
disassembly:
Read all instructions before starting any procedure.
Refer to the motor assembly exploded view drawing, on the page C-17 for the item numbers
referred to in these instructions.
1. Unplug the control unit from the vehicle (four way plug). Do not cut any wiling.
2. Remove the two (2) screws (Item #12) from the connector (Item #18 and #19) on the motor
leads between the motor and the control unit. Remove the seal assembly (Item #20). CAUTION:
Make note of how the wires and connectors are assembled for reassembly later. The wire
connectors may be assembled wrong even though the colors match.
3. It is easiest to remove the motor assembly from the step frame if the step tread(s) are in a
partially extended position. Try to extend the step by following the procedure outlined in Step #6
under the TEST PROCEDURE - MOTOR TEST. If the step is locked in the up position and will
not move, read Steps #4 and #5 below before preceding.
4. Remove the hair pin (Item #6) from the clevis pin (Item #7).
5. Remove the clevis pin (Item #7) from the cast block in the end of the linkage assembly (Item
#8, #9 or #10). Note which direction the clevis pin goes into the cast block. If the step is in its
locked position, the clevis pin may have to be pried or driven out of the block. If the step is in the
locked position, loosening the motor assembly mounting bolts may allow the clevis pin to be
removed easier. The step tread(s) should swing freely when the clevis pin is removed. If the tread
does not move freely, check for a bent step frame and for rusting, at the pivot points.
6. MOTOR REMOVAL - The motor (Item #5 or #5A) may be removed without removing the
gear box or linkage assembly simply by removing the three (3) screws (Item #4) along with the
bearing bracket (Item #2).
7. GEAR BOX REMOVAL- Unbolt the gear box mounting plate (Item #16) from the step frame.
8. Remove the beating (Item #3) and the linkage assembly (Item #8, #9, or #10) from the gear
case (Item #11) along with the adapter gear (Item #1) and shaft (Item #17).
9. Turn the gear box assembly over and remove the four (4) 1-1/4" long #10 self tapping screws
(Item #13) from the gear case. Lift off the mounting plate (Item #16).
10. Remove the bearing (Item #3). Lift off the gear case cover (Item #15) and lift out the gear
(Item #14). Note which side of the gear goes up.
