AIR COMPRESSOR PUMP SERVICE
Compressors draw in air and create a vacuum to reduce volume. The vacuum pushes the air out of the chamber and into the storage tank. Once the storage tank reaches its maximum air pressure, it should turn itself off. If it doesn’t, you have issues….
Now, if the tank won't build pressure because the pump seals or valve plate are worn out or broken, you may need to rebuild the pump. Please remember to use manufacturer-approved replacement parts.
Shut
off the electricity and bleed the air tank.
Remove the compressor belt guard and the belts
off the pump pulley.
Remove the pump from the compressor bed
plate. It’s typically held down with 4
bolts.
Place the pump on a work bench.
Remove the bolts on the cylinder/ valve head
and remove the valve head from the pump.
Take the pump to a test stand and hook it up
to the electric motor. Place a belt on
the electric motor pulley and onto the pump pulley.
Turn on the motor and test the pump for
suction. Listen for any clanking and
grinding. In addition to that, watch the
pistons go up and down in the cylinder head.
It you see oil leaking into the cylinder head…HOUSTON…WE HAVE A
PROBLEM. If you head any clanking…HOUSTON…WE
HAVE A PROBLEM. Leaking oil may indicate
worn seals or rings or damage to the cylinders.
Clanking may indicate broken or worn inserts, broken piston rods, broken
wrist pins; broken or worn crankshaft, etc. etc., etc.
Let’s remove the pump pulley. You will need a pulley puller/ a screwdriver
and a hammer (because you will need to remove the key from the crankshaft) Using
the screwdriver and hammer, gently tap the key from the groove in the
crankshaft. After completing
that task, it’s now time to remove the flywheel from the shaft. Tighten the puller onto the back of the
flywheel; use an impact gun and start extracting the flywheel from the shaft.
Time to break down the pump. Remove the bolts
from the cylinder to the crankcase and remove the cylinder head and DRAIN THE OIL.
Remove the piston/ inserts and rings. Be very careful here not to mix up the
inserts with the other piston rods.
Remove the wrist pins from the rods/ piston heads.
It’s now time to tackle the crank case so you
can remove the crank shaft and bearings.
You will probably need to remove the crankcase cover. Be careful when removing the bolts.
Time to pull out the crankshaft from the
crankcase. Sounds easy but it might take
some elbow grease. You may want to use a press here. Actually, you really should use some sort of
press here as the crankshaft was probably pressed into the crankcase when it
was assembled.
After removing the crankshaft, you will need
to remove the bearings and sleeve.
Again, a good puller will come in extremely handy here. You can always use brute force to remove the
bearings from the shaft but you risk injuring yourself and possibly the shaft.
Since everything is broken down; it would be a
good time to hone the cylinders and wash all the parts carefully. Use fine emery cloth to clean the pistons;
remove all extra gaskets and debris from the valves, cylinder heads, etc.
Before you begin, please remember to wear work gloves to protect your hands and always use some sort of eye protection. And as always, don't forget to turn off the electrical supply to your compressor before attempting anything.
The compressor motor drives a piston that compresses air in the tank. Worn pump parts and seals prevent the pump from filling the tank with compressed air. If the pump won't compress air and fill the tank, rebuild the pump or call H&K PUMP @ 214-428-2868.

Remember,
if you decide to try it yourself, here are just a few tools that you will need:
1.
impact tools, wrenches and sockets, hammers, lock ring pliers, punches,
benches, and screwdrivers
2.
an air compressor
3.
a vice
4.
a press
5.
a torch
6.
wire
7.
a test stand
8.
oil
9.
pressure tester
10.
grease/ lubricant
In
total, you should have around $7K - 10K dollars just in tools and equipment in
order to disassemble and rebuild your air compressor pump...
WHAT DOES
IT COST TO REBUILD MY PUMP?
The cost to rebuild a pump varies from one
machine to another. It typically takes anywhere from 1 to 2 hours to
completely break down the machine and determine what the issues are. To
do it right, you should remove and replace your bearings; replace all the
seals; replace all the gaskets; replace all the rings on both the high and low
pressure pistons; replace the valves along with the valve gaskets; hone the
cylinders and change out the oil. This process with removing and pressing
in the bearings and cleaning up the machine; reattaching all the lines and
testing the machine on a test stand can and will take anywhere from 5-8 hours
depending on the size and complexity of your pump. The average cost to
completely rebuild a 5-10 HP pump is anywhere from $500 - $1,500 dollars and
will take between 2-5 business days to rebuild. If done correctly, it
should last you for decades to come.

WHY?
Because many of the parts are made in China and may be difficult to locate. In addition to that, it would cost more to fix the compressor pump than what it's worth.
