The Head Honcho in Action
Prepping Studs for Head Honcho:
Cam has been removed, but the chain wheel is still on the support bracket.
Stud Prep: Remove the slotted end of the stud and use a 3/8 drill to put a centering cone in the end.
A guide sleeve is placed over each stud to keep the ball bearings in place.
Ready to bolt on the Honcho.
Tool Assembly:
Main plate in place. This shows the relationship between the studs, guide sleeves and the threaded jacking inserts in the plate.
Main plate bolted down. Ball bearings are dropped through the inserts to keep the jacking screws centered on the studs.
Support bars bolted to the exhaust flanges keep the main plate from twisting.
Jacking screws in place. Note that the chain wheel has been removed. Leave it on if you don't intend to replace the chain.
Ready for the lift.
Head Lift:
The lift begins.
Jacking screws are tightened in turn to keep the head level.
The lift progresses.
And some final photos:
This is about as far as you can lift if the chain wheel is in place.
At this point, you would carefully saw the studs off between the head and block, leaving enough in the block to grab onto and twist out.
Or, with the chain wheel removed, you can lift the head all the way off the studs.
