Section 319d states: "Safety straps of the axle box wing lugs and bogie bolster should be adjusted so as to ensure a minimum clearance of 40 mm between the lugs and bottom of safety straps."

Section 319d states: "Put dash pot oil of approved brand in lower spring seat to a level of 60 mm from bottom."

Section 319d states the variation "between two wheel sets in same bogie as 5 mm."

Section 318 states: "Nylon 66 brake gear bushes to RDSO STR No. C-8107 should be fitted in brake gear."

Section 318 states: "Replace the brake blocks if worn out to thickness of 20 mm or below."

Section 316h states: "All the hangers should be tested to tensile load of 8 tonnes."

Section 316h states: "The vertical gap should be within the permissible limit i.e., 384+0.0 mm."

Section 316f states: "If any repair like welding or straightening is carried out, which damages the galvanising, repaint the equalising stay with epoxy paint."

Section 316e states: "Refit new silent block in every POH."

Section 316d (point 7) states: "Chalk test the centre pivot pin 'in position' or 'off position' to detect cracks."

Section 316c states: "The relevant axle guides should be cut using special gouging nozzles (PO 18 or 19) to prevent undercutting of bogie frame."

Section 316c states the wear limit as "0.5mm for BSS bracket bush."

Section 316c states: "If the BSS brackets or axle guides are worn (limits: 1mm for axle guide...), damaged or cracked, they should be replaced."

Section 316b states: "Make sure that the vent screws are opened" before lifting the bogie frame.

Section 316a states: "Wash the bogie with high pressure hot water jet to remove all dust, mud, scales, grease and other muck."

Section 316a states: "Remove all the oil from the side bearer oil bath" before washing.

Figure 3.12 shows the maintenance flow diagram with "Coach lifting" as the first step.

Section 315 states: "Hydraulic shock absorbers with capacity of ±600kg at a speed of 10 cm/sec. are fitted."

Section 313 states: "This device has been provided on bogies between the lower spring plank and the bolster to prevent lateral thrust on the bolster springs."

Section 312b states: "Bogie brake rigging has been modified to incorporate a total mechanical advantage of 7.644 per bogie for non-ac coaches and 8.40 per bogie for ac coaches."

Section 312a states: "In 13 t axle load bogie the four lever used in bogie brake rigging are each with lever ratio of 1:1 and hence the total Mechanical advantage in a bogie is 4."

Section 312a states: "In 16.25 t axle load bogie the four lever used in bogie brake rigging are each with lever ratio of 1:1.376 and hence the total Mechanical advantage in a bogie is 5.504."

Note P1 states: "Bronze Wearing Piece should be renewed when the wear on the mating surface reaches 3mm that is, height is less than 42 mm or damages occur to the oil grooves."

Table 3.2 shows the condemning size for wearing piece as 42 mm.

Table 3.2 shows the new size for wearing plate as 10 mm.

Section 311 defines silent block as: "a synthetic rubber bush fitted in anchor link and center pivot of ICF bogies to transmit force without shock and reduce noise."

Section 307 states: "The springs are manufactured from peeled and centreless ground bar of chrome vanadium/chrome molybdenum steel."

Section 306 explains: "The bolster rests on the bolster coil springs... suspended from the bogie side frame by means of bolster-spring-suspension (BSS) hangers."

Section 305 mentions: "Special screws with copper asbestos washers are screwed on the tapped hole to make it air tight."

Section 305 states: "On the bogie side frames, directly above the dash-pots, tapped holes are provided for replenishing oil in the dash pots."

Section 304 states: "As it is not possible in open line to distinguish between modified and unmodified arrangements, 40mm oil level is standardised for both."

Section 304 states: "These guides are fitted with guide caps having nine holes of diameter 5mm equidistant."

Section 303 mentions: "The wheel sets are provided with self-aligning spherical roller bearings mounted in cast steel axle box housings."

Section 302b states: "No vertical weight transfer is effected through bogie pivot." Section 308 also confirms: "It does not transmit any vertical load."

Table 3.1 and Section 302b both confirm that coach body weight is transferred "through bogie side bearer pitched at 1600mm."

Section 302A states: "Helical coil springs are used in both the primary and the secondary stages."

Table 3.1 specifies "Telescopic axle guide with oil damping" as the axle guidance system.

Table 3.1 indicates that the wheel diameter (new) is 915 mm.

Table 3.1 specifies the wheel base as 2896 mm for ICF bogies.

Table 3.1 clearly shows the maximum axle load bearing capacity as "16.25t, 13t" for ICF bogies.
