Pump Drive Operator’s Manual #1033752

Place the straight edges horizontally along the face of the PTO and

pump drive hubs.

Measure distances A and B. A and B should be equal within 3

mm (0.125 inch) measured 430 mm (18.0 inches) out from the

centerlines of the shaft. If a difference in A and B of more than 3

mm (0.125 inch) is found, the engine should be moved to bring

these distances within 3 mm (0.125 inch).

After A and B have been set the straight edges should be rotated

to the vertical position as shown by the dotted lines in the sketch.

Distance C should be equal to distance D within 3 mm (0.125 inch)

measured 430 mm (18.0 inches) out from the center of the shaft.

If C and D vary more than 3 mm (0.125 inch) measured 430 mm

(18.0 inches) from the shaft center the engine should be moved

until the difference is brought within 3 mm (0.125 inch).

After setting C and D, A and B should be rechecked and reset if

required. Repeat this procedure until distances A and B, and C and

D are equal to each other within 3 mm (0.125 inch) measured 18

inches (430 mm) from shaft centers.

After setting as described above, the engine should be securely

anchored. The PTO shaft centerline and gear head input shaft

centerline will now be within 1 degree of parallel

Note: All threads and bearing face to be lubricated with light oil film prior to
