Pump / Drive Assembly Instructions
4. Loosen Splined Clamp Yoke. Insert a bar
through the Yoke to hold Driveshaft up and to help
loosen the Bolts in the clamp Yoke (See Figure 10).
This can be loosened with a hand Wrench or a
Socket whichever is easier for you (See Figure 10).
Some times it is easier to test fit the Tube End of
Driveshaft to the Pump while the Pump is on the
bench.
Installing Pump:
1. Install Pump into Splined Clamp Yoke. Slide
the Pump Splined Shaft into the Spline Clamp Yoke
(See Figure 11). Leave the Bar stuck in through the
Yoke as shown, this helps to stabilize the Yoke as
you slide Shaft into the Yoke. Once Pump is slid into
the Splined Yoke, keep the Pump supported; DO
NOT let the Pump hang on the Yoke unsupported.
2. Pump / Driveshaft Yoke Gap Adjustment.
After sliding Pump Shaft into Splined Clamp Yoke,
the Pump and Yoke must be slid apart far enough to
allow for a 1/16" to 1/8" Gap between them. The Yoke
edge cannot touch the Pump Housing; it will damage
the Housing and the Yoke if it does. This is a very
critical adjustment (See Figure 12).
3. Tighten Clamp Yoke. After Gap between
Yoke and Pump has been adjusted tighten the Bolts
& Nuts on the Clamp Yoke (See Figure 12 & 13).
Check Pump to Yoke Gap once more. Keep Pump
Supported do not let it hang on Yoke.
