A few chips
GMC outside
New Driven gears installed. Notice two styles of shafts. The two on the left are different then the three on the right. The spools are different also.
Nylon gear sets the operating axial position (runs against the dowel in the trans case). The gear with the most wear was .050 different than new. shoulda used the camera flash
Brushing out the bore,
Some of these needed a good wire brushing to get them clean
Sludge
Cleaning out an orifice in the valve spool
3 1/2 schedule 80 pipe to make seal retainers out of. Pretty close to what is needed I.D and O.D. This stuff doesn't machine as good as some other, gummy like.
Chuck it up short.
Boring to fit over the can top.
Parting, out kinda far so bull nose center to stiffen it up.
Going slow here, no support.
Ring and can top
How it fits on, hold an O ring seal and has a lip to get a screwdriver in to pop it apart.
Together with a slot for prying it back open. Need to tack weld the retainer on. Ripe for weight and spring changes...tune it like you want.
Bail holds it together and in the hole.
can parts.
how the originals fit.
Leaded steel to make governor cans out of. Machines nice.... lots of chips to come, About $10 a linear inch delivered.
Old school calipers
Parting, Used a power hacksaw to complete the cut
Dial in and center drill after a cut
Last two top to top
cutting cans apart
Patients. These are Turbohydramatic 425 transmission governors.
Last two just a stub left
all that is left over
Blanks and a sample
Zero check
Oil it!
Boring
Carnage
Ready to machine the top
Some done. These are the new bottom part of the cans and will seal with an o ring to the original tops. The original was crimped together and not serviceable.
DuQuoin Illinois GMC Eastern States and International rally. Good times.
After the rally we went to Iowa Falls Iowa and went for a walk...
Dam and hydro plant.
On the dam
Redwood Falls Minnesota, there was only one other overnighter here. Campground is right on the river,
Happy Camper.
Filling the GMC LPG tank with a 20 pounder. It works by having a pressure difference caused by the sun heating the small tank and the GMC tank being relatively cooler. Inverting the small tank causes it to transfer liquid making it much faster than transferring vapor. This takes 5 to 20 minutes to happen. I tell when it is done by feeling how the weight changes on the small tank and if it feels like there is liquid still inside. Not sure it would work with the new style bbq tanks with the float deal in them.
Filling a 20 pounder from my bulk tank. Once again it transfers because of a temperature/pressure difference. I do it in the morning as the smaller tanks drop temperature overnight more than the bulk tank. I've put small tanks in a tub of cold water to get it to transfer too. Really cheap to fill the coach and bbq tanks this way. Installed a valve in the bulk tank bottom to get liquid out.
Chuck K had a couple of rear Eldorado disk brake backing plates to modify to fit his GMC. He had a spare spindle I used to get a good fit.
Basically the plates needed to be opened up and a chamfer put on the spindle hole to match the larger GMC spindle.
Dan and Teri Gregg stopped by on their way home. I got to geocache with the experts....
Here is a cache that Sue and I couldn't find ourselves.
Rainbow over a GMC.
