Looking for a little advice here. See item 13 in the attached drawing for the oil pump drive.
The Martin Robey drawing is slightly different than my engine. I have a countersunk hex socket screw instead of the hex cap screw shown in the drawing. I cannot get the darn thing loose.
To date I have heated it with MAPP gas, quenched it in oil, tapped on it with a hammer (gently!) pried, used a hex key and used many colorful metaphors. It won't budge. At the moment it is soaking in liquid wrench.
Any tricks out there for loosening it? I am thinking I need to get a hex key socket for my 3/8" ratchet rather than using a regular hex key. I have broken keys in the past straining to get things loose, and I feel I am close to breaking my current key.
Let me know of any tricks. Next I will try an appropriate key on my ratchet, but I am skeptical even that will not be enough.
Vance
