Glass bead is graded by size alphabetical, A being the finest. A/B grade is the most common but if you can get C grade it will actually do a light peening of the surface and stress relieve it.I hadn't thought of the matching on the gear teeth...like putting lifters back on the same cam lobe. The good thing, this particular truck is so noisy, the gear drive isn't heard
What's "C-Glass"? The gears themselves were hardened...pretty gnarly. I had fun trying to put match marks on them. Is C-Glass like a shot peen material?
Yep, lapping the gears is helpful. On one micro gear box that we did our final lap was done with toothpaste.
Well, it's coming down to the wire...stupid checks and rechecks. Tightening bolts and such. Well, remember when I said I'm not a wood worker? Well, there was some redoing of stuff on the table. We won't get into it, but I need to figure out how to weld wood! So, some clamping and screwing was done (literally and figuratively). So some re-clearing and re-polishing was in order...

Pay no attention to that '33 sitting there...I'll get rolling on that when the Mover's moved out
. It’s pretty much a ground up rebuild at this point.. lol
No painters here now...the two shops I have dealt with are only doing insurance work now. I was told that with the used car market so high, the insurance companies are pushing up what would have been totaled...lots of quarter panels and core supports. I don't know if that's just adjusters up here or not.Ya ever find a paint shop that is gonna make it look nice?
Anyway to clean up the dash and make it presentable? This is gonna be the new real estate vehicle in the fall.. lol
For a while that "Kit" was a "special service tool/bullion" on Cadillac HT 4100sHey Monkey...whenever I build something from scratch (tanked and scrubbed clean) I always add the tabs from GM.. View attachment 1115678
They are like ceramic alumnaseal, seals all the weeps from core plugs, gasket leaks (like your mover) etc when the initial break in is done.
I keep a couple of those packs in my tool box. My buddy was a GM tech, and he said every head gasket or even crate motor, they'd pop some in.Hey Monkey...whenever I build something from scratch (tanked and scrubbed clean) I always add the tabs from GM.. View attachment 1115678

IMO It can never hurt anything, I'd have only used half though because of the limited size of the cooling system.I keep a couple of those packs in my tool box. My buddy was a GM tech, and he said every head gasket or even crate motor, they'd pop some in.
I was afraid to on this thing in particular though. The radiator isn't much bigger than a heater core! Dry fill, the whole cooling system is under a gallon
The school maintenance guys had one of those at my high school, we picked it up and Austin Powers'd that thing in a hallway
I tell him to bring it by, and I'll figure something out. The supplier has now said 6-8 months!
what a cluster fornication of belts and chains. i would be willing to bet the engineering whiz kid who designed that with one tensioner, never had to and will never have to align one. shit like that drives me nuts.Oh, that gear driven machine thing? At week 8, the guy calls up and says, "Hey, my guys blew up the box"
Truck gets there, I drop under it to check the play in the drive...and it feels good? WTF?! So, I fire up the rig, hit the switches, and my stuff's working fine. I was surprised as hell too! So, follow the power flow and see what's not spinning.

Lower middle-left is a shaft supported by pillow blocks. Just out of frame is a big, 4 sheave pulley that has belts running through the floor, to a drive shift on the end of that gear box. Kind of the backbone of this thing, spins the other pumps and stuff. View attachment 1116565
This is another angle, and the other end of that backbone shaft deal. There is a pretty, white box in the center...it's pretty because this is the after pic. That is a 90 degree gear box. It's driven by the big belts, then on the front side spins two hydraulic pumps, and the backside pulley spins a vacuum.
It was dead, drive gear came off. I could have fixed it pretty easy, but the supplier had one on the shelf. What was a real joy was aligning 7 belts along 2 axis and 3 planes...with only one adjustment tensioner. Stupid, but it works.
I won't put the head back in, but started on the adapter/face plate last night. I'll get a pic of it later...it will look pretty decent, much better than it's current state.
Thank you. If I were really one of the car pimps, I'd have had the thing water jet or cnc cut, flow coated with resin and back lit...my imagination out paces my talent and my budget
Info on said motor and pump, you know, for washing down the decks in the channel
love your write-ups.
I wanted more and more, and at some point I realized I was wanting more, but never knew what I wanted. Confusing as hell, but it makes sense in my head. I used to push 70hr weeks. I was just talking with my daughter yesterday about this same thing. She was complaining about working 9 days straight. I explained to her that 10 years ago, in our last house, I remember working 45 days straight. No rain, big bills, keep going.
From what I've seen, it's not only the kids. There are lots of guys my age that have been lucky enough to avoid those scenarios. There are some that will boldly, even arrogantly, say things about others' lack of planning or foresight. Those same people have probably never been in situations requiring long term medical treatments, or unexpected costs such as funerals. I'm happy that not everyone has.
Consider this.
Bottom end is gone. He and his brother in law were going to fix it. They pulled the motor, and started to tear it down. Well, they got to the stator, and we're stuck...need special tools. That was over a year ago, he wants it out.
Crap, screw in a mechanical gauge, it's fine. New sending unit put in. Mess with carb, Quadrajet, mixture screws aren't changing much, if at all. Checking for vacuum leaks, and it develops a slight knock...well, this is new. Call owner, he says "Oh yeah, my mechanic says it's the heater lines knocking as it gets to temp."
On this episode of broken crap: My Mechanic Says...
My response is always, "Why am I fixing it then?" Usually, said mechanic is too busy, but it usually means it cost too much or they couldn't figure it out.
24v Cummins, stopped running. Mechanic said it needed a lift pump. Well, yes, that is true...but...what else died because of it? Tested lift pump, worked but weak. When they get weak, they don't supply enough to the injection pump. Bad for running, fuel is important. The fuel is also what lubricates and cools the injector pump.

A VP44 fuel pump is half-ass electronic. The lines come out the back, but a big plug on top for electronic magic. Well, if you hotwire the pump, knowing which 2 pins to use, you can make the motor run. Not well, but the injection pump will cycle fuel and pressurize. It eliminates any electrical issues and isolates the fuel pump as the problem. Well, it was the problem...well, the other problem. Replaced the lift pump to make sure it was getting adequate volume again. In a bread truck, the pump kind of sucks to do. In a truck, you're looking down on it, and more room in front to pull the gear off the pump. Got it done, they were happy.
Next one: SBC '85 half ton 4x4. New motor, guy says it runs but dies when hot. Fire it up, idles fat, but we'll start looking it over. Oil gage shows 0 when warm
WTF? Well, now I know why you're here...

Tools of the day. Bore scope came out to validate my theory. With a stethoscope, something was angry in the #2 cylinder. Didn't take a pic on the phone, but showed the customer what appeared to be brass or bronze on the piston top...new .030 flat tops. I think a guide came apart. New Chinese aluminum heads...China never built Chevy motors, and shouldn't! View attachment 1149751
Buttoned it back up. Done for now. Engine builder says he'll make it right, and I'll dial it in after the fact...maybe.
Then there was this this week, "My mechanic tried to patch it"
Shoot him...

Different bread truck guy, same business...let's say the deliver stuff...in white vans...but they all know each other. Word gets out I guess at the distribution centers.
First off, that's an Ace Hardware fitting. They have their place, but this isn't it. These pumps are something like 2000psi at idle. The line had split from rubbing. It rubbed because a previous "mechanic" was too lazy to put the keepers back on.
View attachment 1149753
Six new lines, with keepers. These came from eBay I was told...they sucked. All the bends were there, but not always in the right spot. Some tweaking was required. In the end, it's done and owner is happy.
This fits under the mercenary part. There are guys that usually do the general stuff, but apparently I get the stuff others don't want. It's all the same to me, just nuts and bolts. I'd rather do this than brakes and oil changes, that gets boring to me.
