Engine GA000099, An early GA engine rebuild thread Options

[Superhawk996]

Last week I bought engine GA000099 from Freezing914 in the hopes of picking up some spare parts to support rebuild of the engine that came with my vehicle.

During the teardown of my vehicles engine, it is quickly becoming clear that the engine was abused by some DAPO. Cooling flaps and thermostat had been removed. Rust in the sump. The crank was scored and already 0.010" undersized. The oil pump was torn up. This is just the tip of the iceberg on the engine that came with my vehicle. (IMG:style_emoticons/default/chair.gif)

14 hours of driving seems to have netted me an engine that might be worthy of a rebuild. (IMG:style_emoticons/default/piratenanner.gif)

This engine appears to be bone stock. D-jet mostly complete. As an added bonus I discovered upon teardown that none of the cooling tin fasteners have ever been disturbed. No screwdriver marks!

But . . . like any engine of this age and unknown origin, it absolutely needs to be gone though.

Gotta ask...what kind of knee mill is that?

1950's vintage American Iron - about 1600 lbs worth. (IMG:style_emoticons/default/biggrin.gif)

South Bend Vertical Mill. It's a bit different in that it doesn't use standard R8 collets but uses a NT30 taper but has a weird countersink in the taper for holding the taper into the spindle rather than using the threaded end like a standard NT30 or CAT40. I end up buying NT30 tooling but have to grind in the countersinks on the taper to use on this machine.

I like it because NT30 is a positive drive vs. R8's that can be prone to slipping.

Price was right ($500 delivered) back when I bought it a few decades back.

Contemplating adding a VFD so that I can get spindle speed down to 40-45 RPM. Then I can cut my own valve seats. (IMG:style_emoticons/default/idea.gif)
