15. 15K SRW. Check 15K SRW gear oil level every 6,000 miles (9,654 km) or once every six months, whichever

occurs first. Refill 15K SRW with GO specified for ambient temperature. Change oil every 12,000 miles (19,308 km)

or once every year, whichever occurs first. Use procedure (a) to check and fill oil level; use procedure (b) to change

oil.

a. Check and fill oil level as follows:

(1) Shift the freespool mechanism to the disengage position so the drum can be freely rotated.

(2) Rotate the drum to where either plug is near the top of the 15K SRW. Remove the plug.

(3) Rotate the drum 90 degrees in the direction that allows the other plug to be near the top of the 15K SRW.

Remove the plug.

NOTE

Oil level is full if a small amount of oil runs out of lower plug.

(4)

Add oil until a small amount of oil runs out of lower plug hole.

(5)

Apply adhesive (Item 3, Appendix D) to plug and position plug in top hole.

(6)

Rotate drum until open hole is at top.

(7)

Apply adhesive (Item 3, Appendix D) to plug and position plug in top hole.

(8)

Tighten plugs to 13-15 lb-ft (18-20 Nm).

b. Change oil as follows:

(1) Shift the freespool mechanism to the disengage position so the drum can be freely rotated.

(2) Rotate the drum to where either plug is near the top of the 15K SRW. Remove the plug.

(3) Rotate the drum 90 degrees in the direction that allows the other plug to be near the top of the 15K SRW.

Remove the plug.

(4) Position drain pan (Item 39, Appendix C) under 15K SRW.

(5) Rotate the drum until either hole is straight down to the bottom of the 15K SRW. Allow the oil to drain

completely.

(6) Rotate the drum until either hole is at top.

NOTE

Oil level is full if a small amount of oil runs out of lower plug.

(7)

Add oil until a small amount of oil runs out of lower plug hole.

(8)

Apply adhesive (Item 3, Appendix D) to plug and position plug in top hole.

(9)
