Hi ,Crazy horse. information perfect . with a14.5 inch pully on the compressor and amotor running at 3450 rpm you can get with a 5 inch pully----1189.6 revs per min ---- with a 4 1/2 pully ---1071..6 revs per min so you hve to decide whether you want the max or the min from that compressor... If it was for me I would use the 5in . and set psi. with the cut in ---cut out switch ,this will be a good unit ,,if you need any more help don`t hesitate to call and thanks for the opportunityto help it is great when some one gives you good info .you did well

The motor turns the belt that drives the actual compressor portion of the system. Replace the belt, make sure there is oil in the compressor pistons and try it out.

Ok, sounds like you are having water vapor condense in your crankcase, must be pretty humid where you are.1- Make sure the crankcase has a vent on it somewhere.2- Be sure you are running the compressor long enough to get the oil hot enough to evaporate any water that does get in there. If the compressor is over sized and just runs a few times a day it may not run long enough to flash off the water that does collect.3- That unit looks pretty big if you sized it to spray paint with it may be way too big for your normal shop use (see 2 above).

i dont have so much as a solution as a couple of things you can try to figure out whats going wrong.

make sure your compressor can handle 10.5 CFM @ 50psi
hook up the gun and dry spray it to check for blockages in the air supply
if the air comes through strong and constant, fill the paint hopper with water and spray until empty
if the water comes through constant, add half of the hopper with paint thinned with penetrol or floetrol
if the paint is coming out weak or spotty, make sure the vent cap is open on the paint hopper
if the cap on the hopper doesnt have a vent, try spraying with the cap off or cracked a bit.
if that doesnt work take off the hopper and check the filter for blockages.

i suggest straining all your paint before pouring it into the hopper
