Worked on the injection pump leaks today. Typical of the CAV pump that the kill shaft, accelerator shaft and top cover were leaking. I won't go into detail about the procedure because that has been discussed many times on this forum and others. I will offer pics that other post are lacking in. Orings and gasket at the local dealer were less than $5.00
The nuts inside the black circle are the only thing that holds the top cover on and are somewhat fragile so don't over-torque on reassembly, also they have a sealing washer under them.
Remove the top cover gently
Pay attention to where the spring hooks in what someone else coined as the "tombstone". Mine was in the bottom slot, also on the other end of the spring there are three choices so check that location also
A view of the "tombstone" circled with green and the kill lever circled in red
In red is the bottom of the kill shaft that fits into previously mentioned kill lever
In green is the bottom of the accelerator shaft with a good view of the three spring choice holes, mine was in the center (look close and wear in that hole is obvious)
Both shafts shown, the orings were hard and brittle causing the leaks. I installed new orings with a generous amount of Vaseline in the center groove and a little on the orings.
The gasket has a couple tabs, tab goes under the plate as shown in the last pic.
Ran it for half an hour and no more leaks on the injection pump.
