What I always wanted to know for Puch 500, 650, 700, Haflinger and the small boxer engine

How do I measure the engine oil level correctly?

Answer: The engine oil level is measured with the measuring rod inserted and should lie between the 2 markings (Min-Max). It is best to measure before an engine start. Do not screw in during the measurement and do not fill it via Max!
A fiber sealer should be located in the threaded part of the measuring rod.

Which oil do I use for the small boxer engine?

Answer: Mineral SAE 20W-50
Ideally mild alloyed vintage oil. See test on the Internet.

What air pressure should I drive?

Answer: Here are some guide values, may vary depending on the tyre type, tyre dimension, ground condition, load.

Puch
VA 1.4 – 1.6 Bar
HA 1.6 – 1.8 Bar

Haflinger
VA 1.6 – 2.0 Bar
HA 1.8 – 2.2 Bar

Which battery should I buy?

Answer: 44/45 AH are completely sufficient in normal maintenance condition, dimensions depending on the installation possibility.
In the Puch rather the high form. At Haflinger also like a little more capacity.

How does the ignition belong?

Answer: Ignition time static approx. 8-10mm before OT (test lamp
), contact distance 0.4 mm (sensor g
auge)Candles Heat value 225 – BOSCH W5AC or comparable, electrode distance 0.7 mm

Which spark plug is the best?

Answer: ALL if the values are correct and ignition and carburetor setting are fine. The candlelight is usually not due to the candle.
Original BOSCH W5AC (0 241 245 580)
Thread M14x1,25, thread length short thread 12.7mm, SW 20.8mm, tightening torque 20-25 Nm.
Also suitable with heat value 225, electrode distance 0.7 m
m: NGK B7HS, Champion L82C, Beru 14-5A etc.

Do I need an oil bath air filter?

Answer: Rather no.
For the hard work, this type of filter was standard at that time and installed in the 700C and mostly in the Haflinger.
Old bunnies claim it costs performance. A conversion in the Combi is usually not sensible due to the structural conditions. With Haflinger, the sole use of the paper filter is a good way to do this.

How big must the valve clearance be?

Answer: 0.15 mm for inlet and outlet valve. Measured in a cold state.

How often should I check the valve clearance?

Answer: For retracted engines, all 5,000-10,000 KM in the course of a large service.
Further testing is required in the event of an initial loss of power or start difficulties with a warm engine.
With a newly built engine, it is recommended to test for about 400-800 KM, because the heads like to sit down a bit.

Workshop – Air

The throttle valve wave

Where there is air is life – sometimes also a life of its own.

This article is about the original carburetor types of the Puch engines, especially Pallas Zenith 32NDIX and Weber 32ICS. There is excellent literature on this, without which a carburetor overhaul should not be carried out!

Where to buy
Autoquariat, Puch Club Salzburg, Prokschi

The oldi runs strangely, sometimes the engine goes out, sometimes it turns too high. The ignition is fine, the centrifugal force adjustment in the distributor is smooth and resets? What can it be?

Too much air? Wrong air?
They are getting old, the carburettors. They used to do what they should. Cleaning them, assembling a new sealing kit is only half the work. A cleaned carburetor looks good, but an often neglected error lies in the throttle area.

A beaten throttle valve shaft can be easily tested with sensitivity. Is the wave wobbling up and down in its leadership? This is the case for many of the Puch carburetors today. Gasoline leaks and air enters through the wave game. At a point where it shouldn’t be.


There are now new shafts, some with slightly larger diameters and good quality bearing bushings and sealing rings. This can be used to correct the problem described. The testing and overhaul of other components in this context, is not here content of this article.


With the help of precise tools and machines, the holes are revised and restored to target state. In the case of the 32NDIX, it is immediately upgraded to the last stage with X-sealing ring.


The motor thanks it with better conrun, with defined mixture formation and precise adjustment capability. As in the past…

The car must be in the fresh air

Ideas are good. Even better to put them into practice. Sometimes it takes a wedding party. And a Puch 500. But now in turn.

The title itself is not quite correct, but it is understood. Often enough, there are standing-up vehicles that best turn into vehicles through species-appropriate movement. With the help of special ideas and supporters from our circle of friends, a project has developed for this purpose, this story is to report on this. The last entries are always up here, behind this line. Continuing…

History
Every historical vehicle has one. Dealing with it is exciting and often makes you want more. What was the state of extradition? Who was the first owner? What is all of it today? Everything is evolving, not always in the right direction. Depending on who is looking at it. Colour, rims, tyres, the use of modern materials are keywords here that will continue to be discussed here in the future.

ome are closely connected with their Pucherl, give him names, celebrate wedding days and gladly share their joy. This is how a first spark for our project came about years ago. Surely it will get a name later, let's call it "Art-friendly outlet" at the moment.

Not seen for a long time, finally the wheels turn again. Some of the vehicles had disappeared from the scene for more than 30 years. Put away for time reasons, but never forgotten. After extensive restorations, they return to the street or into offroad.

We are pleased with the proud owners to finally be able to experience them again in 2020.
