Disc plates 271695-5 and 271693-5 and thrust plate
271696-2 can now be removed from shaft 271690-1.
This leaves the output end of the shaft free.
Removescrews 271730-12 and the manifold head 271687-1.
Bearing pin 271688-2 and valve plate 271689-1 will
become free with the manifold head.
Remove nuts 180226-10 and lock washers 191344-3.
Remove the hydraulic motor housing 271688-1. Slip
cylinder block 271689-4 off of the pistons. The
output shaft with attached parts can now be tapped
free.
To dismantle the cylinder 271693-1, and the parts
that were removed from the B-end as an assembly, it
is first necessary to obtain, from the tools provided
with the spare parts, four each of the spec ial
assembly screws 271732- 3, nuts 271732-2, and washers
271733-1. Then remove four al terna te screws 200075-6
from retainer 271691-1, and assemble in their place
these special parts, with the washers held against
the retainer by the nuts. Removethe remaining four
screws 200075-6. The retainer is now held in place
by the special assembly screws.
Gradually unscrew the assembly nuts 271732-2 until
the spring is no longer under compression. Then remove
assembly screws and the retainer with bearing
271731-6 and spacer 271688-4.
It is highly important that the cylinder is dismantled
according to instructions. The purpose of the
special screws is to restrain the compressed spring
271694-3 to prevent possible damage by the retainer
springing free when the screws 200075-6 are removed.
Further dismantling of the B-end is apparent from
the drawings.
