NOTE:
If you are installing the auxiliary valve block onto a
windrower paired with a D60 header with reel fore-aft
functionality, the windrower will already have an auxiliary
valve block installed.

and install them in the countersunk port holes from which
the plugs were removed.
4. Attach the smooth side of valve (C) to the lift valve with
four 3/8 in. bolts (D). Use the longer bolts if there are two
auxiliary valve blocks.
5. Torque the bolts to 34 Nm (25 lbf·ft).
6. Replace fitting (A) and plug (B) (removed in Step 1, page
40) into the auxiliary valve block.
