PETTER - PAZ1 - New project
« on: August 16, 2018, 12:51:38 AM »
Greetings my good fellows

I'm starting this new  thread here because I did not find another more precise to make known the progress of this new project.

I took this afternoon to see if my "new" PAZ1 could be resurrected.

The bad news: fuel tank with a huge hole.

To do: disassemble the fuel line; improvise a temporary line (see photo - final version); bleed (+320 crank turns) the bubbles never stopped ... and finally it is alive.
Next step: disassembly, sandblasting, straightening plates, primer and paint.

Difficulties today: lack of English spanners. Once more improvising.

I'll post the project advance.

Best regards to all
Pedrosa

At some point I realized that transpiration wasn't enough to fulfil the task, therefore I took a break to inspiration (see foto). Please note the important is that I cannibalized my 10 year ago hidrolizer project, because it has the BSP right to fit the injection pump.
Fell free to watch the video.https://drive.google.com/file/d/1dhZgPIi0LQkGf44bzjQNN_2lnCSRJu4g/view?usp=sharing

See you later.

Welcome sirpedrosa, and congratulations on the new project; considering it's age I would call it in great original condition.

I too am a fan of the PAZ1, and it is certainly in better condition than any of the ones I have, especially the sheet metal and fuel tank.

What are you planning on installing it on?

Hi  Willw

By now it's only to make it pretty. After i'll figure something to it to run.

This afternoon I changed the oil - there was some sludge in the bottom of sump.

3 lts (metric conversion) of good mineral oil and it runs smoother.

I want to strip it down, but i need the workshop manual. I all ready ask help with this task.

Please, if you have it in pdf format, send it.

Best regards
Pedrosa

NOT very tight if it's a flare fitting .   

A compression fitting with ferrule is not as reliable. Ferrules can never be reused once they have been compressed

Finger tight, and then just a tiny bit more.  The shape of the fitting is what seals, not the torque of the nut.  Too tight and you ruin the fitting.

Again, it's the shape of the metal-metal interface that seals, not jamming the nut on super tight.

The IP creates high pressure, much like brakes in a automobile.   
Steel brake lines also use this sort of fitting, but since it's harder steel, it's more difficult for DIY at home, often it's easier/safer/reliable to but the pre-shaped line.

Hi Mike90045

Many thnks for reply, but is not that torque I mean. It's the (20) tighten in the body (1). It took some strength to unscrew it, I say quite a bit.

the body BRYCE is Aluminium.

Now I need the toque limit to tight.
