Soggy rear

The springs may be soft and the car low but the dampers was TOTALLY gone.
Pulled them out and, yes, they were beyond crap.
Also had big dents in them?
Looked up the number on them and they was from a 80´s BMW 3-series?!?!
Found replacements online but I don't think they would do the trick anyway.
Started to look for Hi-Jackers instead...
Found a suitable pair online for a reasonable price and had them home in just two days.
Thanks Dalhems !
Mounting was a breeze...when the already adjusted rear axle bend was done.
Next up routing the lines.
First find spots where to drill so i get the lines in to the trunk.
Slipped parts of rubber hose over the very thin and fragile? air line.
Put zip tie mounting tabs under the car and secured the hose/airline to it.




Also wrapped some fabric tape on couple of spots if I saw a potential rub.
First routed it under the car, free from hitting objects like the rear axle.


Then in to the trunk ad up to a bracket where I mounted the air went.


Made a tidy little bracket for the air nipple


To adjust the pressure I will use my handy Ryobi Hand compressor.

How did it work out??
Better than expected actually!

Actually beginning to regret I lifted it, now there is a real suspension and I might swap the old lowerings block back again.
...time will tell
But until then I have a great riding car that even can take passengers in the backseat.
That was totally impossible before, not even the dog could sit back because the rubbing and hitting.


A clip to see the movement.

Dripp, dripp

Suddenly this winter i discovered a l puddle of fluid on the floor under the front.
It was the (very old) radiator that finally gave up.
Just in the middle of the core?
Doesn't matter where, it must be fixed anyway.
I removed the radiator, found a number on it which lead me via Google that it was from a 60´s Mercedes Diesel.
Took it to the legends at “Herdbergs Kyl” with an eternity in the business.
I just entered the door and I heard “thats for an old Mercedes”...
Yep, they know radiators.
Had a chat with them if that radiator really was up for the job paired with my Smallblock.
Borderline, but I can upgrade the core when I change it he said.
Awesome! So now it will be three row core instead of two.
That gives almost 30% better cooling and of course it's not +50 years old.
And top of all, it is just to mount it back together with all the old hardware instead of fabrication that another Radiator require.
HUGE win

Taildraggin'

The miles I put on the car last year was sometimes a bit noisy due to the non existing rear dampening and VERY soft springs.
Major scraping and hitting constantly, diff housing even made a dent in the floor.
The springs will stay for now, but I did a rise to get some clearance.
The car is lowered with blocks as usual in these applications.
So I removed the +4” blocks and replaced with 3” and even cut almost 1” of them.
Resulted in a almost 2" rise.
Not only did the rise the rear, they made it a bit lighter going from homemade chunky steel to aftermarket aluminium instead

Wrap it up

On the old exhaust the section over the rear axle was wrapped with heat shield. Primary to protect the fuel pump and the fuel tank. 

Probably a good idea so after my re routing of the exhaust I gave it a wrap again. 

My re routing seams successful, the clearance to my old shock, mocked up with duct tape to the same diameter as the new thicker Hi-jackers looks enough.

Re routing

Had many different noises from the rear axle area last season. 

Didn't take long to figure out that it was suspension related so when I got the car on jackstands it soon became clear that one of the big things was the left damper rubbing the exhaust just by the over axle bend. 

Couldn't move it in any direction so the answer was to extend the bend instead. 

Some universal bends, and some VERY crappy welding later I think I'm fine. 

This problem would have been worse this year because I will go to Hi-jackers and they are almost 1" bigger in diameter than my old worn out dampers. 

So this was unavoidable. 


The before and after routing.
The X is where I had the rub.

314

Even with NO activity in the shop something is going on.

Bought an engine to the rally Zündapp back in October 2019.

Of course the cheapest one and of course in parts.



Have wrenched a fair bit of Zündapp engines over the years, but this engine type I bought this time is the newer 314 type that I haven't ever wrenched.

No worries, have friends who can wrench them so with warm hand I gave this job to my mate Lars in my Zündapp team.

The seller said "it only missed one of two parts otherwise it's great".

Yeah right !!

Didn't take Lars many minutes to see it was far from complete.

Part for this engine are available but just NOS parts and they ain't cheap.

Lars helped me to keep an eye on eBay and parts came up, I bought them and now the renovation will continue.

How did it turn out??

Time will tell...
