PURCHASED A PUMA PK-65 PUMP. AFTER VIEWING THE PUMA WEBSITE AND THE CS WEBSITE IT WAS DETERMINED THERE WAS A MAX RPM DISCREPANCY. I HAD ALREADY ORDERED A 3.5 INCH PULLEY, BUT IT WAS DETERMINED AFTER DISCUSSION, I NEEDED A 4 INCH. COMPRESSOR SOURCE ACKNOWLEDGED THE ERROR AND I WAS ABLE TO SEND THE WRONG ADVISED PULLEY BACK FREE OF CHARGE AND GET THE CORRECT ONE. SHIPPING WAS VERY VERY FAST AND APPRECIATIVE. THESE FOLKS ARE GREAT, BUT,I CANT SAY THE SAME FOR THE PUMP. THE WEBSITE SAYS 14-22 SCFM BUT I ONLY GOT 13.8 AT 90PSI USING THE WEBSITE CALCULATOR. I WAS HOPING FOR A BIT MORE, BUT I WILL DEAL WITH IT. I WISH I HAD WENT A DIFFERENT ROUTE ON THAT. BUT, WITH THAT BEING SAID, THE CUSTOMER SERVICE WAS SECOND TO NONE AND I WOULD GLADLY BUY FROM THESE FOLKS AGAIN.

Cast Iron 5.5" Triple Groove 3 Belt B Section 5L w/ 7/8" Sheave Bushing
Masterdrive triple groove 5.5" cast iron pulley/sheave with a 7/8" H-bushing for B section belts is a high-quality 2-piece pulley that measures 5.5" outside diameter and is designed to be used with an H-style bushing. The bushing inserts into the center of the pulley and slides over the shaft, as you tighten down the bolts on the H-bushing it will tighten down on the shaft making this style of pulley much more secure than a standard single-piece pulley. The bushing is made of solid steel and precision machined to ensure high quality and secure attachment to your motor/engine shaft. This pulley accepts B Section also known as 5L series belts and is 5/8" wide. This pulley will work with A Section belts A, also known as 4L; however, they will sit farther down in the groove, reducing the pulley size by 1/4" to 1/2" on average, depending on the size of the pulley.
