Dailey Engineering offers oil pump driven pulleys utilizing a taper grip locking mechanism.  Our taper lock pulleys eliminate the need for set screws so the oil pump drive shafts remain undamaged when adjusted or removed.  Our pulley hubs are available for 5/8 drive shafts and 1/2 drive shafts.  We currently carry 8mm HTD tooth sizes from 25 to 46. 

We have guide washer styles in selected tooth counts.


We also have selected twin pin and 1" bore crank pulleys along with a variation of drive mandrels that are not commonly found by other manufacturers.  These are usually custom made for systems we have designed.  



Dailey Engineering stocks a full line of 8mm HTD belts available in 10mm and 20mm wide belts listed below.

Dailey Engineering offers oil pump pre filters for installation into standard AN fittings.  The filter is captured between the flare of the hose end and fitting.  To install in any existing system you simply undo the hose end, install the filter into the fitting and reassemble the hose end.  Available in -10 and -12 with a 730 micron filter rating, these are used to protect the scavenge inlets of the oil pump.
