cover [171] as drive shaft cover.
5.4.5.1

Disassembly

Loosen the hexagon socket head cap screws [195]. Before removing these bolts, screw two stud bolts
into the threaded holes at the top of the cover.
Although no alignment pins, the speed increaser gear casing cover does not drop by itself even
when the bolts are removed because it is fitted on the thrust bearing gland located inside.
However, when you go on the disassembly work of this block without screwing the stud bolts, there
is a risk to damage of the speed increaser gear spindle by dropping the cover.
Make sure to screw in the stud bolts beforehand.
Tap the cover gently with a hammer to loosen the gasket which is sticking to both mating surfaces.
Pull out the speed increaser gear casing cover in a direction parallel with the shaft.
Removing Speed Increaser Gear casing Cover
 At this time, ensure that the speed increaser gear casing cover is supported to
avoid it toppling or dropping onto the shaft (spindle axis). Protect the shaft with a
cloth beforehand.
