NOTE:

This Operator’s Manual covers several models. Features may vary

by model. Not all features in this manual are applicable to all models and

the model depicted may differ from yours.

Flexible Pump Coupler

The flexible pump coupler is a nylon “spider” insert, located between

the pump and the engine shaft. Over time, the coupler will harden and

deteriorate. Replace the coupler if you detect vibration or noise coming

from the area between the engine and the pump. If the coupler fails

completely, you will experience a loss of power.

NOTE:

Never hit the engine shaft in any manner, as a blow will cause

permanent damage to the engine.
1.

Disconnect the spark plug wire and ground it against the engine.

Remove the three flange lock nuts and hex screws that secure the

pump to the coupling shield. Two flange lock nuts and hex screws are

at the bottom corners and one is in the top center. See Figure 7-1.

Remove the pump.

Loosen the set screw on the pump coupling half and remove the

coupling half.

Rotate the engine by slowly pulling the starter handle until the

engine coupling half set screw is at the bottom. Loosen the set

screw using an allen wrench and slide the coupling half off the

engine shaft.

Slide the 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 the coupling half). Tighten the set screw.

Install the nylon “spider” onto the engine coupling half.

Install the pump coupling half and key on the pump shaft. Rotate

the coupling half until the set screw faces down. Do not tighten

the set screw.

Align the pump coupling half with the nylon “spider” by rotating

the engine using the starter handle. Slide the coupling half into

place while guiding the three hex screws through the holes in the

pump support bracket.

10.

Secure with the nuts removed in Step 2.

11.

Set .020” to .090” of a clearance/gap between the nylon “spider”

and the engine coupling half by sliding a feeler gauge between

the nylon “spider” and the engine coupling half and moving the

pump coupling half as needed. Install the set screw and torque to

78 in-lbs to secure the pump coupling half. See Figure 7-1.

NOTE:

Make certain the proper clearance/gap is obtained before

tightening the set screw.

12.

Reconnect the spark plug.
