1.5 Visually check that the bolts and nuts linking the bogies and link
sections together are not loose
1.6 Inspect the rubber stoppers on the bogie (see fig.2 or fig.3 in
manual) for cracks. Replace both stoppers if necessary
2. Every 1 000 000 axles
2.1 Measure and write down the diameters of all 48 guide wheels.
New wheels are 99mm diameter. Wheels on the same axle
should not differ by more than 0.5mm and the diameters should
not be allowed to reduce to under 95mm.
2.2 Measure and write down the width of each guide wheel.
New wheels are 33mm wide and should be replaced when
reduced to under 30mm.
2.3 Inspect the polyurethane tire of each guide wheel for cracks or
other damage.
Some cracks are allowable, but if bits of polyurethane starts to
break off, the wheel should be replaced. The centre wheels on
the bogies carries more load than the others. Wheels which
start to show signs of deterioration may be exchanged with
others in positions where less wear occur.
2.4 Check the spring centre pin bush on each of the 8 suspension
springs.
Refer to fig. 8. The left hand flange of the spring in the
drawing has a Vesconite bush through which the centre pin of
the spring slides. (The nut and spacer shown in the drawing
will normally not be there). The hole in the flange is larger
than the diameter of the centre pin, leaving a clearance of about
1.5mm all round the 16mm pin. If the bush wears, the pin may
touch the flange, wearing the pin. Check that the bush is in
place and that the pin does not touch the side of the hole.
2.5 Refer to section 4 and apply a small amount of grease to the
sidewalls of the guide wheels.
