    Default 22JD Tear down!

    Well guys, Been sitting in the office in 65 degree air and decided the time for the 22JD tear down was on! That Kroil stuff works and them some! My biggest fear here is any damage to the cylinders. I got a selection of square punches (Never use a round punch on a square indentation). The tuff one I thought was going to be the cap clamp nuts but with a couple of hits they started spinning. The valve pocket set screws came right out with an impact driver as did the primer bodies. The top cylinder plugs also came right out with the impact. Tomorrow we hit the intake manifold. Got to run to sears and get a 1.750 wrench. If they don't give, I'm going to make a sheet metal sleeve to protect the manifold and hit it with the mini-abrasive wheel and slit the packing nuts. Mark if your around I included some new pics of the rockers. I can't tell you people what a load off my head this was tonight. This is going to be a great thread. Bob L

    Look good's Bob and it sound like your tearing into it,I found a good way to break the intake manifold nuts free is using a old radiator wrench its the same as a Stilson big adjustable but it has no teeth to mar up the nut surface good luck on the tear down

    Billy, you just hit on the head. The packing nuts are shot. Why am I going to go and buy a wrench when I can just put a pipe wrench to it? Some times when you’re tired you can’t see the forest in front of you. Thanks for the suggestion. Bob L

    Rob, I have special pullers that I built twenty-five years ago that will shred that valve stem before they will let go (Lathe collets). Will see you and Lucy a Jefferson, we got a lot of ground to cover. Until then, the rebuild goes on. Bob L

    The rocker towers look like the 1917-1922 style but I'd have to see the underside to be sure. You do however have the pre 1923 intake valve springs, so that's a good sign.
    Taking intake housings out is a snap. Once you have the cylinder off, remove the keeper, collar, spring and cover from the exhaust valve. Also make sure the housing set screw is out and use the exhaust valve as a drift to drive out the housing. A few gentle raps with a lead hammer will get them out and also not damage the end of the exhaust valve.

    Good afternoon Gentlemen, Well it was time for round two today. Out the door at 8:00am on a 1500MG vitamin C high and raring to go! The cylinders are off and there is no scoring or wrist pin damage. They mike out at 3.427. I don't know what standard is? As Billy subjected, I had an adjustable flat stilson wrench in my on the road pouch. Two taps of the old ballpein and the manifold nuts loosen right up. Now the intake nipples are another story, they ain't budging. Going to soak them some more, use some heat and hit them with the impact. Mark, I followed your suggestion to the tee and the pocket valves came right out. Just hit them using a drift made of maple. It pays to have 25 wood wreaking hippies on the floor above you. There is also a shot of the bottoms of the rocker housings. The exhaust valve guides are also not moving. There was enough of the thread on the generator shaft showing to see it was a left hand nut but the gear isn't moving. Should I just put a gear puller on it? The only screw up today was that I mixed up the exhaust valves before I had a chance to mark them. Is the sprocket nut right or left hand thread? My wife Bean stopped by the shop and confirmed that the paint is a dark green on the cases. Nice to have eyes that work. Until the next chapter, drink much beer and be happy! Bob L
