(a) Remove the bolts (21), the washers (22) and the gage assembly (40) from the location of the aft datum side-roller.
(b) Set the micrometer (42) on the gage block (44) to zero.
(c) Install the gage assembly (40) on the gage block (44) and lock it in position with the clamps (41).
(d) Move the micrometer (42) in the gage block (44) until it touches the gage assembly (40). Lock the micrometer (42) in position with the screw (43).
(e) Remove the gage assembly (40) from the gage block (44).
(f) Install the serviceable datum side-roller (20) on the gage block (44) and lock it in position with the clamps (41).
(g) Adjust the micrometer (42) until it touches the datum side-roller (20). Write down the dimension shown on the micrometer (42).
(h) Use an MICROMETER - EXTERNAL to calculate the dimensions for the shims (23) from the data written down.
(i) Remove the datum side-roller (20) from the gage block (44).
(j) Keep the side-roller (20) and its shims (23) together.
(k) Do the procedure again for the forward datum side-roller.

WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.

B. Installation of the Datum Side-Rollers

NOTE: This procedure is only necessary where all the side-rollers are removed.

(1) For tracks 5 and 11, prepare the aft datum side-roller (20) for electrical bonding (Ref. AMM TASK 20-28-00-912-802).
(2) For tracks 6, 7, 8, 9, 10 and 12, apply a thin layer of Synthetic Oil base Grease-General Purpose Lithium Thickened - (Material No.03GBD1) to the interface of the datum side-rollers (20) and the shims (23).
(3) Apply a layer of Polysulfide Sealant-Low Adhesion Brushable - (Material No.06AEA1) or Polysulfide Sealant-Low Adhesion Fillet Structure (Material No.06AEB2) to the shanks of the bolts (21).
(4) Put the necessary thickness of shims (23) and the aft datum side-roller (20) in position.
