Koni Adjustable Shock Won't Adjust...'84 FC

David- you got a good coach. The Konis have a warranty with them.

David I went through the same thing on my shocks last summer The one
would adjust & the other one acted the same as you described it . I couldn't
get
it to adjust. Three did & one didn't. I ended up buying two new ones.

Took the left one off to adjust, and when pushing the shock down to
engage the adjuster, it just spins. I can feel a slight detent, but
pushing as hard as I can and even tapping with a mallet, it won't
engage. Any other secrets to these shocks? Thanks.

David,

You might want to check the compressed height of the
shock and compare that to the length between the chassis
shock mounts when the chassis air is dumped. The Koni
adjusting nut may have been damaged due to the shock
bottoming before the suspension bottoms. If so, you may
be able to pick up a few tenths of additional shock
travel by lining up the Koni adjustment nut with the foot
valve assembly after they are installed on the chassis.
Note, this only works when at least one end of the
shock is a stud mount.

David,

Can't do that as both ends have holes to mount on studs on the
chassis. I might add that these shocks are stamped "Koni-Holland"
and have the Blue Bird logo on them, so I'm supposing that they are
the correct shock for the application.

When both ends are mounted on studs, you can still align
the adjustment mechanism, it's just that your choices of
adjustment become more limited. You would need to adjust
them in half turn increments, and when they are finally set,
the adjustment cogs may need to be rotated slightly to line
up with your mounting studs.

IOWs, start by rotating the adjustment nut so that the two
mounting holes are parallel. From this point you can adjust
in 180 deg, half turn, increments and you will then be able to
mount to the chassis and the adjustment nut will align with the
foot valve assembly.

Also, the stiffer you make the shock, the shorter the compressed
length becomes. So to really give yourself extra clearance, make
them full stiff and have the adjustment nut align with the foot valve
assembly.

I don't know why the shocks are too long, but it could be that
over the years the tolerances in part specs were pushed to the
limits. Monroe's became Koni's, firestone airbags became
goodyear, etc, etc. Each change, while within spec, ate up a
little tolerance and subsequently clearance. Of course, this all
assumes that indeed your shock is bottoming before your
suspension. I would measure that.

Best regards,
David Brady
