"BIG FOOT 31"
having concentrated the last months more on refurbishment of the house, I now
started with some improvements of Big Foot.
the first thing is the air snorkel issue! Because of a friendly hint from a
person from a web forum (thanks to Klaus) - who has as well a Mercedes and in
his Avatar I recognized the air snorkel – I got the address of a dealer of
used trucks and truck parts (LKW-Stietzel,
pls. look as well Big Foot links) where I bought the unit for Big Foot.
Prior to be spammed with request: I got the last one they had! My search hint:
Look for companies close to you dealing with used trucks or parts of them and
visit them. To call them in advance does not make sense from my point of view.
1. Some may not want to sell to end-customers because of the European warranty
clauses 2. Due to my expe rience they don’t know, what they have in stock!
(Same applied for me: I arrived there and explained what I am looking for which
caused a sceptical look. Thanks to Klaus I had a full description in which of
their halls and where to look. Unfortunately there weren’t any left. Finally
we went outside to the cabin wrecks and on one of them there was one final air
may be your question:
lift of the air intake from 1,5 m to 2,5 m minimizes the amount of dust by
snorkel contains a cyclone. As a result the air starts to spin and the
heavier dust parts are falling into a reservoir (it’s a kind rubber bag
and by squeezing, it opens on the bottom and the dirt or dust can fall out)
instead of jamming the normal filter.
the main reason: It looks extremely IMPOTANT!
you can see the 3 parts.
picture shows the necessary modifications. Primarily I had to move the radio
antenna which I had unfortunately mounted on the right side. But this is exactly
the place for the air snorkel!
I had to remove all the inner coverings, remove antenna and cable and fix it on
the left side, then squeeze the antenna cable into the left window pillar and
finally using hot gluing (MIG /MAG welding is more likely hot gluing if I do it
- rather than real welding!) to fill the previous holes and then grind the
welding joints. Because my plan for this year is a full painting of the body I
sprayed it without too much care, just to keep rust off, fine-tuning will follow
later! The previous drills are marked with the small arrows from left. For the
new clamping devices I drilled holes and fixed nuts, then grinding and spraying
the welding joints as above (big arrows from the right).
picture shows a hole for a captive nut. It was used for the original air intake
as well and I moved it to here. Here a silent block is still missing. The silent
block on the right side was part of the air snorkel.
I have mounted everything just for test purposes.
course I had to shorten the radiator grill. After cutting it off I ground the
edges and sprayed it.
silent blockis on top of the cabin for the air-intake-housing (here I have
welded in a nut) in addition to the two clamps fixing it to the edge of the roof.
In addition you see the 4 welded in screws for the air horn.
The air-horn was not working because a paper-seal had shrunk. So I replaced it
and than connected it to the compressor. First: It now workes again. Second:
With approximately 5 or more bar the noise is THAT loud – unbelievable. So the
pressure pump being part of the air horn will be history and I will connect the
horn now to the pressure system of the truck by using a electric air-valve
everything was taken off again, primed and finally sprayed in dull-black. Of
course all screws were exchanged against those of stainless steel.
my wife said: “ We are not going to drive with a car painted in red from the
primary colour???” So I filled the scratches with body-filler, sanded it and
than primed & painted it in dull-black as well.
