Newsletter April 2019

| As
previously mentioned in Newsletter 10 a lot of preparatory work
happened before the big re-wheeling could take place. In
fact it started in July 2018 on the day the wheelsets and axle
boxes came back from Ian Riley's works. Two different squads set
to work, one group, Bob Kelly Richard MacDonald and Davie Wilson,
started to clean and paint the wheelsets. The other group started
to work on the axleboxes. |
||
|
||
|
||
| The
axleboxes had received new white metal bearing surfaces at Riley's and
the team of Dave Bird and Malcolm Mathers began filing to put a
chamfer onto the edges of white metal. This is to give a lead in
for the oil so that it will form a continuous film over the axle's
bearing surface. |
||
|
||
| The
oil is drawn up from the axlebox underkeep and fed to the underside of
the axle via an oil pad. THese are springy metal frames comvered
with a woollen padwith wooden tails (strands) trailing down into the
underkeep. These were purchased from the Armstrong Oiler Company,
a subsidiary of the North Yorkshire Moors Railway. Prior to
being fitted teh pads for the pony truck and back bogie were
thoroughly soaked in a tank of axle oil so that they were completely
saturated. The underkeep can be filled manually or supplied by
the mechanical lubricator. |
