(4) are 43-1/2 inches long including fittings
and both lower hoses (5) are 38 inches long in-
cluding fittings.
MODEL 15D-2 ONLY: Both upper hoses
(4) are 41-1/2 inches long including fittings
and both lower hoses (5) are 36 inches long in-
cluding fittings.
Installation of hoses and connections as
outlined here are for the right side. Installa-

"0"
rings are in the proper
location.
4. Position the short hose (5) with the fit-
ting (3) ove r the bottom hole of the cylinder
. manifold.
5. Place two hose clamp-halves (2) over
the hose, catching the shoulder of the fitting
(3). Secure the clamp-halves to the manifold
with four 3/8 x 1-1/4 inch cap screws and lock
washers.
6. Position the long hose (4) with the fit-
ting (3) over the top hole of the cylinder mani-
fold.

Step 5.
8. Position the hoses (4 and 5) with the
fittings (6) at the bulkhea:d.
9. Place four clamp-halves (2) over the
hoses (4 and 5), catching the shoulder of the
fittings (6). Insert eight 3/8 x 2-1/2 inch cap
screws through .the clamp-halves and bulkhead
to hold the hoses (4 and 5) into position.
10. Clean the four holes of the hydraulic
pump manifold. Place an
