Have a old (1950's guessing) westinghouse air compressor. Pumped it to 150 psi, I shut off, air was coming out of air intake and had pressure in the crank case.

replace the non-return valve in the pipe at the tank connection
air out of intake is poor poppet/read valve seating and pressure in the sump is the tank air leaking back and down past the rings
150 psi is excessive and not good for the compressor so adjust it back to 100 -110 psi

Convert scfm to cfm? my compressor puts out 4.9 scfm at 90psi; 7 scfm at 40 psi so how many cfm at 23 psi?

Hard to give an exact number, however, as pressure and temp of air increases, the scfm drops as you see in your numbers. With low pressure such as 0 thru 25 the temp of the air is also low/nominal thus the scfm will be very close to the actual cfm listed for the compressor pump.

Can I get 80 psi with dials set at 40 psi

this compressor should be able to fill your tires to 80 psi. Look for a pressure switch and adjust it so the motor shuts off at a higher pressure. Do not exceed 100 psi.

A/C unit no longer cooling. Showing pressure at 100 psi.

did you use a manifold gauge, HI and LO side, if your compresor is not engaging probably due to a low charge, because your gages must read about 15F below ambient temperature that translate to on a 80f day uyour gage must read about 95psi on hi and lo (no compresor running)with compressor runing your lo side must be around 35psi and your hi side around 200+ psi depending on amount of air cooling your conderser, also note charging amout tag to not overcharge system, on other hand your problem may be a electricall, check your fuses and MG/C cluth relay by pass it to confirm your compresor is in good working condition.

How much air (p.s.i.) should there be in the front and back shocks


Depends on what you want to get. In theory the fork can be between 0 and 43 psi. In practice if you put 40 psi it will be completely stiff and seals may start leaking.

In practice the front take 0 to 12 psi, and rear shock from 7 to 21 psi.

If you need street performance put more pressure. Settings for comfort in long travels will require lower pressure.

Here tables from service manual:




Rear shock absorber air pressure can vary from 0.5 kg/cm2 (7 psi) to 1.5 kg/cm2 (21 psi) as the road conditions become more severe or the load increases.

For the front here below the procedure from service manual. I suggest staying far from the 43 psi limit suggested if you do not want to break the seals.

8. Make sure the front wheel is off the ground and inflate the forks to 0-0.4 kg/cm2 (0-6 psi). Do not use compressed air; use only a small hand-operated air pump.
Never exceed an air pressure of 43 psi (3.0 kg/cm2) as damage may occur to internal components of the fork assembly.

My compressor gauge does not go below 50psi and when i turn it on the gauge goes up to 180 psi

This sounds like the gage is out of calibration. 50 psi sounds about right for this model. I believe 120 psi is max press. and it should pop the safety at 130 psi. Drain the tank, it has a drain at the bottom of the tank. Remove the gage from the fitting. It should read 0 with it out of the system. If it does not read 0 she is out of calibration. I do not believe this gage can be calibrated back to 0 if it is sprung. You will have to find a new one or do the math in your head. If the gage does go back to 0 once removed. Your regulator is bad, you can try to rap it with a hammer handle to see if that will get it back in line. Next step would be to replace the regulator assy. Hope This Helps Fix Ya up.

What horse power is required for producing 16.9 CFM at 100 psi or what horsepower is required to produce 16 CFM at 175 psi We have an air dual stage air compressor and need to find a motor to fit that will...

You are looking for about 5 H.P. to do that, but what is more important is the r.p.m. of the motor, the size of the pulley,,, and the size of the compressor pulley! most manufactures will spec the pump for certain horse power,,, they go hand in hand,,, for example you cannot take a pump designed for 5 H.P. and hook a 10 H.P. motor and a bigger pulley on it and spin the pump faster to make more air,,, it wont take that high of speed,,, I hope this helps.

Hi. I just bought one and can't figure out how to get the pressure to start increasing? the power runs ok but the pressure is still at 0. thx

you could check the bleed valve.
it is located under the tank,
put on the unit and place your hand over the valve,
if there is air coming out of it then that is your problem.
some valves are made to tighten and some are made
to loosen. important stop the air from coming out.
if that is not the problem contact me for a next tip.

Compressor won't kick back on when its suppose too

The tank check valve is probably bad. Folow the large discharge line off the head, disconnecting one end of it. If you get air out of the line you have a bad check valve. If you don't get air you are probably looking at a valve job.

Compressor Support

Home Use: Compressed-air power tools can dramatically decrease the amount of time spent on a project. Many homeowners will use smaller, portable units (either hand-carried or wheeled) that move easily from the garage to the house, yard or roof. Common air toolsAir Tools such as brad nailersAir Nailers, reversible drillsAir Drills, and impact wrenchesAir Impact Wrenches require about 0–5 CFM (Cubic feet per minute — units in which air flow is measured). It's important to know if the compressor you purchase will drive the air tool you'll need for your project. For example, smaller air nailersAir Nailers run on 2 to 5 CFM at 70 to 90 PSI, while larger shearsShears, sandersSanders and polishersPolishers require up to 10 or more CFM and 100 to 120 PSI. Business Use: Air compressors used for business/professional applications are often classified “industrial grade.” They're packed with features that let you take on more demanding jobs with more horsepower, more CFM, more PSI and more (longer) run times. Though some industrial-grade compressors are portable, many are stationary units with large-capacity, ASME certified air tanks (up to 120 gallons), greater HP, more CFM air volume and faster recovery time to run a wide variety of air tools for as long as you need them to do the job.
