1. Remove three nuts that secure the pump to the coupling shield.
Two nuts are at the bottom corners and one is in the top center.
See Figure 5-2.
2. Remove the pump.
3. Rotate the engine by slowly pulling starter handle until engine
coupling half set screw is visible. Loosen set screw using allen
wrench and slide coupling half off engine shaft.
4. Loosen set screw on pump coupling half and remove coupling half.
5. Slide new engine coupling half onto the engine shaft until the end of
the shaft is flush with the inner portion of the coupling half. (There
must be space between the end of the engine support bracket and
coupling half). Tighten set screw.
6. Install pump coupling half and key on pump shaft. Rotate coupling
half until set screw faces opening in shield. Do not tighten set
screw.
7. Install nylon "spider" onto engine coupling half.
8. Align pump coupling half with nylon "spider" by rotating engine
using starter handle. Slide coupling half into place while guiding
three mounting bolts through holes in pump support bracket.
9. Secure with nuts removed earlier.
10. Set.010" to.060" clearance/gap between the nylon "spider" and
the engine coupling half by sliding a feeler gauge or matchbook
cover between the nylon "spider" and the engine coupling half and
moving pump coupling half as needed. Secure pump coupling half
with set screw. See Figure 5-2.
NOTE: Make certain proper clearance/gap is obtained before tighten-
ing set screw.
