This is the coupler that connects your engine to your hydraulic pump. Includes your engine side coupler for your Onan "B" or "P", the rubber spider inbetween the couplers and also the coupler for your hydraulic pump WITH 3/4" shaft. Option to Choose a different pump shaft size if your is not 3/4"
 
NOTE in OPTIONS you can choose instead of ordering the complete coupler, you can order each component individually (PumpCoupler, Engine Coupler or Spider.)
If you choose to get a coupler half ONLY, then select "KEEP STANDERD SPIDER"
 Option under "spider options."  And you will get the coupler half you selected only and will not be charged for a spider. 
 
OPTION - To upgrade spider for couplers from standard rubber to urethane. Urethane is harder and has more torque capacity and better wear. Slightly more vibrations may be felt as it is a bit harder. Urethane is recommended for all loaders.
 
NOTE- "Lovejoy" - "Love Joy" Is a manufacturer brand of these style couplers as many different manufactures make them, but often they are all referred to as "Lovjoy" couplers. We use many brands, including Lovejoy and others, we also have a good selection of New Old Stock as well as brand new couplers. All of equal quality. The NOS may have some scratches, etc, on them but are NEW. Couplers may vary from photos but will be the same speced and quality item. We are able to offer competitive pricing on these items for these reasons and bulk purchase and pass the savings on to you when we can.
 
SHOP TIP - We always recommend changing the spider anytime you take the couplers apart. If couplers and / or spider show any wear, always replace! Leave a small gap between metal halves so they do not touch when installing.
