8. Clean all the parts in solvent, dry them off, then

reassemble and retest the valve. If the flow control

valve tests OK, reinstall it in the pump. If the flow con-

trol valve still leaks air, replace the pump as an assem-

bly. The flow control valve is not available separately.

NOTE: If necessary, relief pressure is adjusted at

the factory by adding shims under the check ball

seat. If you found shims in your valve, be sure you

reinstall as many as you took out.

3. Install the new ball bearing using a press as shown.
2. Remove and discard the ball bearing using a press
