4. Driveline timeing means the universal joints are both the same position when driveline half is slid together. If
they are not timed, it will decrease the life of the universal joint and in some cases could cause a vibration. (See Figure
2 & 3), Driveline timing is critical to smooth operation.

5. Install Tube End of Driveline / Pump End. Slide
the Tube half of driveshaft through Pump Mount Plate and
Tractor Crankshaft Access Hole (See Figure 8). You will
have to align the Universals when doing this (time the
Driveshaft). Slide the two together where the Universal are
in time (See Figure 2, 3 & 5) this will help the driveshaft
to operate smoothly.
6.
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 6). This can be loosened
with a hand Wrench or a Socket whichever is easier (See
Figure 6). Sometimes it is easier to test fit the Tube End
of Driveshaft to the Pump while the Pump is on the bench,
But this make timing the driveline yokes more difficult.
7. Install Pump into Splined Clamp Yoke. Coat the
Pump Splined Shaft with Anti-Sieze Compound. Slide the
Pump Splined Shaft into the Spline Clamp Yoke (See
Figure 8). Leave the Bar stuck in through the Yoke as
shown, this helps to stabilize the Yoke as you slide Pump
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.
8. 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 9).
