ASSEMBLY
Assembly is essentially the reverse of disassem-
bly procedures. However pay particular attention
to the following.
2,4,5,14, Bearing and Crankshaft
Apply Loctite 767 anti-seize on part of crankshaft
where bearing fits.
Prior to installation, place bearings into a container
filled with oil, previously heated to 75°C (167°F).
This will expand bearing and ease installation.
To properly position the outer PTO side bearing
no. 5
on 717 engines or the outer MAG side bear-
ing
no. 4
on the 787 engine, a distance gauge
must be temporarily installed against the inner
bearing. Slide the outer bearing until stopped by
the distance gauge, then remove it.
