Hi Bob
So glad to see your beautiful GPA coming together!! You are doing a very fine job with it! I have considered it a pleasure being able to supply you with some of your missing parts! :D

I would like to Thank You Bob for all of the many hours it must have taken to research and put together and then publish all us GPA folks with the one and only indepth full color GPA books ever! I, over the years, have referred to it many times. I even decided to purchase a second book to keep on the coffee table! :lol:

Also, a big thank you for sharing with us for over a year now, your entire step by step story of the quest to restore this original GPA 12350! I am sure you have enlightened many readers over the months!! I got to thinking that there will be a adjustment period once you have finished your GPA, I will miss reading all your post and waiting for those "to be continued" posts, maybe you can figure out a way to say "to be continued" after the finishing post of the GPA taking a swim!

All the best
David

Thank you very much David 8)
I will do my best for the follow up program with water adventures.
But !!, to be honest: I will never do such a challange again.
I was just in time to get the missing parts.
And got most of it, thanks of the GPA friends of the last years.
If I had to start today with such a project, I don't think I will ever get it complete. :roll:
If you want to restore a GPA, start with a complete vehicle as possible.
And people are talking about prices of a complete GPA,
Yes, very high today, but if I make a calculation to get mine that far........
not counting all the hours................
But, the cream of the cake is comming soon when I am driving and swimming :D

Hi (GPA) friends,

Holiday for me and the work goes on at GPA 12350.
Made a lot of progress the last weeks :D
I installed a not original extra 12 volt electric bilge pump,
Image
Also an extra brake-booster, also not original, but the GPA is 500 kg heavier than a normal Jeep,
and when you come out of the water, brakes are more bad!
When your engine will fail, no pump !, and when you have a leak, I think you
are pleased with an extra 12 volt pump :)
The dash is now installed and the front deck.
Installed the engine lid and left and right covers.
Image[/url
This is done after I made the dog clutch drive shaft and the dog clutch engage shaft.
Image

This could only be done with dash on it and engine in it.
Luckely all works fine.
Now I am conecting all wires and all the extra wires and units.
I installed also a not original over pressure pump on the breathers of front and rear axle.
Yes, also not original :roll: :D :shock: :lol:
I hope this will keep water out of the axles when I am in the water.
A small leak in a seal or gasket, and water will come in.
In this way I hope in that "hole"now air push out the water.
Then it was time to start the engine again, now with dash and instruments installed.
I was very pleased that there where no oil leaks, and my original generator was charging.
Image
Image
I have installed the main water propellor bearing (Thanks Leo), and the drive shaft for this,
and water propellor works great!
Also installed the exhaust pipes and mufler.
For me unknow, because my first GPA didn't has this unit, the extra grill and rod on top of the mufler.
After some "finding outs" I managed to get this installed in the correct way.
Image
Also installed some extra's already on the vehicle.
Image
Image
Now I am working to get the wiring system complete, and I am working to get the indicators and brake light good.
Then I have to fill the braking system with flued and test this.
Then floor pannels can be installed and seats.
Indeed: :D :D :lol: will be continued!

Gpa5510 has a small compressor connected to the Axle vents and the steering knuckles via the fill hole. I regulate the pressure to about 4or 5 psi. Works great!

"I am going slightly mad"

Post by bobassel » Mon Aug 03, 2020 9:26 am

Short update;
I filled the breaking system with fluid (silicone) and waited until the master cilinder was full, and all air bubbles were out.
I inspected the master cilinder and the whole floor was filled with flued. :evil:
The after market extra plastic cilinder was leaking because of a crack. :twisted:
Hopeless with a lot of after market products.
I ordered a new one, hopefully better quality.
So now I started again with filling the master cilinder, and bleeded the system.
Only two minor leaks that I could easily solve.
I finished all the electric wiring with all extra's for getting my licence plate and papers for the Dutch law.
Licence plate lightning, two breaking lights, two indicators, small "town" lights and the electric pump for the axles,
the 12 volt bilge, compass light etc etc...
Also made four springs for the lifting eyes.
Made some new breakets for the pick pole on the right side, and installed the pick pole.
Image
I tried to adjust the sealed beam headlamps for both on the correct level.
When I pushed the foot switch they were working the other way arround???
I thought I had made a mistake in the wiring, although I worked carefully on this.
Red wires together and also black wires.
I lifted the front deck and discovered everything was O.K. ????
Then I checked the plugs / connectors in the headlamps and all the connections were ok ????
It turned out to be an internal mistake in a sealed beam unit!
In my whole career of working on vehicles, I never experienced this.
Will be continued.....

Wow, your enthusiasm is truly inspiring. I am currently trying to purchase a GPA project and looking at your detailed posts it proves what a massive job restoring a GPA can be. Hopefully one day, I'm posting photos of my project on here.
Thanks for taking the time and effort to keep posting pictures and descriptions on here.
