M121 mortar carrier ... mounting the 120mm mortar.

Dear MSG Half-Mast,

I need info on mounting the M121 120mm mortar to the side of the M1064 mortar carrier. I can't find anything in TM 9-2350-277-24P on the mounting bracket.

Dear Sergeant M.P.,

The TM does come up short on mounting brack info. Here's what you need for mounting the M121:

Order the lever release bracket with NSN 5340-01-285-0619. To mount the lever release bracket, you'll need a lock washer, NSN 5310-00-584-5272, and hex head screw, NSN 5305-00-071-2071.

Order the lower mounting, bracket with NSN 5340-01-286-0470. To mount it, you'll need a lock washer, NSN 5310-00-584-5272; flat washer, NSN 5310-00-184-8992; and hex head screw, NSN 5305-01-325-8388.

There are no repair parts for the lower mounting bracket, but there are for the lever release bracket:

* locking pin assembly, NSN 5315-01-386-3977

* manual level, NSN 5340-01-285-0135, which includes a flat washer, NSN 5310-01-292-7760; locking washer, NSN 5310-01-285-0128; and locking nut, NSN 5310-01-285-0130

* non-metallic bumper, NSN 5340-01-285-7512, which includes spacer plate, NSN 5365-01-292-7763; flat washer, NSN 5310-01-285-0123; and hex socket screw, NSN 5305-01-285-0116

The angle bracket for the lever release bracket is not available. You will need to order the next higher assembly, the rim latch, NSN 5340-01-285-0619.
