You really don't want to pound on the end of your crank and bearings with an impact wrench. That bolt isn't that tight, but a 1/2" breaker bar with a 1-3/16" socket is probably what it will take. You will need to lock the flywheel to keep the crank from turning while you do this. > Some interesting stuff > from the outside and the #1 & 2 cylinder side of the engine, though. > The thermostat had self-destructed at some point, so badly that when we > first pulled the engine Monday night, I thought that there was an > accordion-like piece of plastic, like a shock boot wedged between the > lowest cylinder tin and the pushrod tubes.

My interpretation of this has usually been that the engine has been overheated. Make sure that you have ALL the sheet metal bits present and installed correctly as you put the engine back together. Study the exploded views in the Bentley manual. >The pushrod tube for #2 > intake had been crushed by the force of the apparently rampant > thermostat and the pushrod shows wear marks from the pushrod tube. The cause of these wear marks is probably as you say, but if you find them on other pushrods as well, then it is a sign of over-reving. The stock pushrods will flex and hit things if the engine is revved too high. > The engine > number is T0095591, Muir says that's a 1965 1600. The early cases have 6mm studs for the oil pump, a bit of a weak point. You can use a late pump with 8mm holes, but you HAVE to be careful to line up the pump correctly since it is no longer piloted by the studs. The early engine (-66) came with a single drilled crank which provides less oiling to the rods and also fits the (different) flywheel differently. So there are lots of differences that you should be aware of, many of which affect reliability. > It's got single port > heads and 32-PDSIT carbs rebuilt by Bill & Steve's.

They will crap out in a disappointingly short time since they have thinner walls which will eventually warp. Stick to stock, or bite the bullet and get the case and heads machined to fit your pistons and cylinders. > Can a 009 be run > on a 6V system, or will I have to keep the stock dizzy? The 009 should work; the only question is whether the larger current (lower voltage. higher current) will damage the points quickly. OTOH you may find that the OE dist is a pretty good match to your needs. Jim - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA *******************************
