What is Air Compressor Bumbing clearance? How to Check and adjust it?



1.     Start the Stand by compressor.
2.     Stop the compressor whose bumping clearance has to be taken.
3.     Isolate the system.
4.     Put “Men at Work” tag.
5.     Loosen the cylinder head bolts and lift it.
6.     Measure the diameter /size of the lead ball.
7.     Bring piston to TDC and put lead ball on centre of it.
8.     Now, put the cylinder head and tighten it to required torque.
9.     Now, again loosen the cylinder head bolt and remove the ball.
10.   Measure the size of the ball.
11.  The difference between the initial size and final size is the bumping clearance.
It can be adjusted by either putting a thinner gasket or putting shim on top half

  1. In a two stage tandem air compressor adjusting the first stage bump clearance will effect the bump clearance in the second stage,so how does it work out?

  2. Proper maintenance of an air compressor is necessary to ensure that it functions smoothly and is safe to use. Compressors that are not maintained properly can stop functioning and can also jeopardize you safety while using it. If you have an air compressor you need to know how to effectively maintain and store the device.

  3. Keeping your {air mechanical device|compressor} well maintained can actually confirm however long your compressor can keep it up kicking. There ar many easy steps to making sure your mechanical device remains in best condition, and you actually will not regret the time you pay caring for your tool. The compression that happens within the air tanks of your mechanical device causes wetness to accumulate within those tanks. That wetness, in turn, runs the danger of oxidization out the tanks, and doubtless destroying a paint mixture (if used with a paint sprayer). On very cheap of the mechanical device there's a wetness unharness valve; it's crucial to unharness this valve with each use, this could stop rust or alternative water injury. AN in-line filter may also be be purchased for any mechanical device to eliminate water mist in your air lines.
