Re: Stuck Head
My head puller:
I started with a 8" x 12" × 1/2" piece of steel from the scrap yard at 35 cents/lb.
1. Drilled and tapped holes for 7/16-20 x 6" bolts that thread through the plate and sit on the 8 head studs surrounding spark plugs 2 & 3. I used a spare head to mark the needed holes. I used fully threaded 7/16-20 x 6" bolts but they are nearly impossible to find and pricey. You can use use 7/16" threaded rod with nuts welded on top. Don't use a larger diameter as it has to pass through the holes in the head,
2. Drilled two 1/2" thru-holes (not threaded) for bolts that screw into spark plug lift adapters *.
3. The brass 3/8" NPT hex nipples are used as alignment spacers that sit on the 4 head studs under the corners of the plate to keep it in place and aligned as it raises.The nipples may need to be slighty drilled out to slip easily slip over the bolts.
I used it this morning and the head started to lift with just a couple of turns of the 8 bolts. Randomly tighten each of the eight bolts just a turn or two to keep the head level as is raises. When club members borrow this, they will thank you and bring you beer
* The spark plug lift adapters are available from Snyders for $4 each. They are not in the catalog but ask for part# A-17022-LE. Or you can make your own from old spark plugs.
