A '62 has to get back on the road

[Braunschweiger]

I agree with you about the camper top, but it can be set up for weekend vacations or meetings within an hour, which I think is nice.

[Braunschweiger]

Today we got a small motorcycle from 1961 for a friend, 50cc and 5.4 HP,
his dad rode it in the 60s, He was already a cool kid back then,
great memories.
The Driveshaft goes to the Driveshaft Shop this week and is overhauled.
Let it run jacked up and I could see the second part of the wave going back and forth. Bumper is upside down.

Nice update

[Grizz1963]

I also bought a 67 onward bumper for my truck, years ago.

I much preferred the look.

Cool bike, but 50cc is not enough for me.

[Braunschweiger]

We are now a group who have a lot of fun with the little things.
When I was 16 years old, my buddy and I rode bikes like this via Marseille, the whole Cote Azur to Monte Carlo and over the Maritime Alps and Switzerland and back again,
when you're young you do things that others say you can't do.

[Grizz1963]

I wanted to ask before Harald

You do not have a red historical plate on the truck.

What do you need for that?

Or are you not bothered?

[Braunschweiger]

Yes, the “H” at the end of the license plate stands for historic vehicle, even for trucks. Many people drive the old pickups with truck registration without an "H", so the tax is based on weight and the tax is around €165 per year and you have a little more freedom in terms of construction. Since everything was approved for me, I also received the "H" and could also use it to drive into the environmental zones of the cities. The “H” then costs €192 per year.

[Braunschweiger]

Actually I just wanted to replace my broken Pinion yoke, the join was running to the sides and wasn't guided cleanly and because I also have humming noises, I immediately got an overtaking kit for the differential.
The differential has been overhauled before.
The differential also came out of the case very easily, which surprised me.
On the Pinion the bearing behind the yoke was broken, all other bearings were undamaged and running cleanly.
Pinion was assembled with a new crush sleeve and new yoke, the crush sleeve was broken and the preload was set to 19 inch pounds, a stupid job under the truck.
But the carrier has 0.20mm(0.00787inches) axial play, which is far too much, it is supposed to have 0.010 preload, backslash is also too much at 0.45 (0,0177inches).
I first ordered shims for the carrier and a solid spacer for the Pinion and will probably have to readjust it.

[Braunschweiger]

Well, replacing the Pinion yoke just now turned into an overhaul,
a Pinion bearing was broken, the contact pattern on the differential wasn't okay
and there was no preload on the carrier, so everything was new.
Instead of a crush sleeve for the Pinion, I installed a solid sleeve and re-calibrated everything.

[Grizz1963]

Excellent work.

I would not know what to do or where to start.

This sort of work always just makes me smile and thank God someone knows how because I have no clue.

[Braunschweiger]

Thank you, i appreciate your answer.
I'm not satisfied yet, I also picked up the overhauled driveshaft today and put everything together.
Did a test drive and I find the differential runs rough.
From 55-60mls it's quiet. I need some advice from you.
What did I do: the Pinion got new bearings and was assembled with a solid spacer and achieved 19in-ibs as pre load and the carrier also got new bearings,
the backlash was set to 0.009 in. I thought the bearing image was okay.
It's an 8.5 10Bolt axle with 2.41:1 locking from 1978.
I would be happy if you could help me with this, thanks.

P. S Here are the pictures from Drive and Coast

[Braunschweiger]

I wish everyone a merry Christmas
and that your projects don't take too long.

[Grizz1963]

Merry Christmas Harald.

Thank you for your wishes.

I trust you and your family will have a wonderful time.

[Braunschweiger]

Update on my rear axle, I looked at the bearing pattern again and came to the conclusion that the pinion is still too low,
I corrected it and am now happy.
Some of the noises are gone, the other noises were still there,
I jacked up the truck and ran it without wheels and brake drums,
I am now going to replace the wheel bearings, why didn't I replace them at the same time?
I'm an idiot.
I will use the repair bearings.

[Grizz1963]

Technicallities beyond my ability and understanding

Good luck.

[SkinnyG]

That looks like a very good pattern.

Are they aftermarket gears? Some are just noisy.

[Braunschweiger]

This is an original GM differential from a 1978 Pontiac Firebird with a 2.41:1 with Limited Slip.
It was a little neglected, but drives well behind a TH350.

[Braunschweiger]

Some of you will remember the Model A that I am now building.
It has a ragtop from Legacy which I have now fitted
and the 4Banger is at the engine builder.
Behind it will now be a 4-speed gearbox from a Volvo.
I got the gearbox at the weekend.
The torque pipe will remain.
A Model A from England has already been built like this, here is an example photo.
And the parts for it are available here in Germany.

[Braunschweiger]

I have now installed new axle shafts with new bearings.
I initially wanted to use the repair bearings, but that was a bad idea.
I assume that because of my limited slip differential I couldn't put the C-clips in, or only with force, but the C-clips would never have come out again.
So I stopped and changed to new axle shafts.
Now the C10 runs without rumbling or vibrations.

[Grizz1963]

That’s a lot of clever stuff you get up to.

[Braunschweiger]

Well, I don't know, anyone else would have done it when rebuilding the differential,
you had a picture on your site with the winding path to reach your goal,
I guess I am the same, but I appreciate what you say, thank you.

[Shifty One]

I really like your build Harald, even with the difficulties!

Aaahhh yes.

I am sure we all could add our names in in place of the Grizz part.

Agreed.

Harald, being in Germany, like many of us outside the USA have added difficulty in progressing builds.

But it’s also inspiring to see plans being made and executed.

[Braunschweiger]

Thanks.
That's exactly what I meant.
Today was a test drive that took us to the Harz National Park.
In one of the pictures in the background you can see the "Brocken", our highest elevation in northern Germany at 1142.2m,
which was a symbol of the division of Germany and was a restricted area for a long time, as the Sowjets had listening and observation stations on the summit.
All history, we are allowed to go back up the mountain.
We had a small local treat at the Oker Dam, the truck now drives as it should without vibrations and noises from the rear axle.
It was a nice trip.

[Grizz1963]

Niiiiiice.

That looks good.
