Hot, hazy days have your Multicyl feeling sluggish? Unfortunately humid ambient air is a reality
in most plants. This humidity can freeze
on the mufflers of the exhaust valves.
As the valve freezes over, the cylinder cannot vent the air
out fast enough and the return stroke becomes “sluggish”. To alleviate this problem, the muffler can be
removed, which will cause greater exhaust noise, or it can be replaced with a
larger muffler with more surface area.
Another common mistake that is made is installing a muffler
or air line on the exhaust port of the MC series cylinders (the NPT threaded
hole between the air and the oil cylinders).
Installing a muffler or breather vent here restricts air flow and
therefore restricts the speed at which the cylinder operates.
Dusty shop floors are another common cause for system slow
downs. At the back of the foot valve, there
is a breather vent.
These vents can become clogged with dust and will negatively
impact system performance. This is a
very easy fix. Simply remove the vent
and either blow it out with an air gun, or in extreme cases, wash it first in a
solvent tank, dry, and reinstall.
