Overhaul

15. Use a suitable pair of pliers and remove the pump

lever shaft. Pull out the lever and the diaphragm.

16. Clean the pump housing carefully and replace worn

parts. Install the diaphragm and the lever on the dia-

phragm shaft. Then insert the shaft and tighten it with

the screw. Assemble the two housing halves and install

the attachment plate (1). Then install the spring (2) and

the O-ring (3).

Valve lifters

17. Check the valve lifters for wear. Replace them if

necessary.

Camshaft

races. Also check the wear of the bearings. The bear-

ings are pressed into their locations and must be line

bored after the installation.

19. Place a support under the camshaft gear and use a

hydraulic press to remove the gear.
