(ii) BG wagons having, face plates not permanently 15 days

(iii) MG wagons with permanently secured face plates 3 months.
having oil holes
The quantity of oil to be injected in each BG and MG axle box is 227 ml.
For oiling the axle box, the wagon need not be damage labeled and brought to
the sick lines. The oiling of wagons should be done in terminating and originating
yards or if they arrive in sick lines for repairs other than re-packing work.
On the left side of the sole bar on both sides of the wagon PRO/PR particulars
are to be stenciled. The former is for plain bearings and the latter is for roller
bearings. Against P, the date of POH and the name of the Workshop is recorded,
against R, the re-packing date and station code of the wagon depot is recorded and
against, the oiling date and station code of the wagon depot is recorded. When the
wagons are repacked in Workshops at the time of POH, date of re-packing should not
be recorded as P includes re-packing also. Similarly, at the time of re-packing date of
oiling should not be recorded as re-packing includes oiling also.
605 P. PROCEDURE FOR REPACKING OF AXLE BOXES
While re packing axle boxes in sick lines, the following procedure should be
followed:-
i. Accumulated dirt both at the end and at the rear end of the axle box should be
removed with a scrubbing brush, scraper or with the help of other material
such as condemned dry waste. Both rivets of the face plate should, thereafter,
be cut by oxy cutting pneumatic cools or by sledge hammer and chisel.
ii. Remove the faceplate and then extract the wooden keep. It should be
examined, and if found to be standard and undamaged, it may be reused after
cleaning. The wooden keep should be kept in a bucket or a small drum
painted red on the outside.
iii. Remove the front roll and the centre rolls and put these in the same red
container. Lastly, remove the back roll which should preferably be put in a
separate small red painted container. Clean the axle box from the inside and
remove white metal pieces, if any. Place back the face plate so that it can stay
in position with the help of its lip. Thereafter lift one or both boxes on the
same axle at a time, for removal of the key plate and the bearing brass.
iv. Wipe the journal clean and feel with hand, right-round to ensure that there are
no rough marks, on any portion of the journal. Measure the diameter and
length of the journal by gauges. Chalk mark the length and diameter of each
journal on the body panel just above the axle box.
