About the SHS CNC O-type Motor Pinion Gear

This is a replacement/upgrade motor pinion gear from SHS. It will work on O-type and D-type shafts. We often use these combined with upgrade motors for an optimal motor pinion engagement as some factory pinion gears are less than ideal out of the box.

The motor pinion gear is the tiny gear that is mated to the motor and meshes with the bevel gear inside the gearbox. When the motor is given power, it spins the shaft which the pinion gear is mounted to. The pinion gear will turn the bevel gear, which turns the spur gear, which turns the sector gear, and pulls back the piston. This tiny gear does a lot of work for how insignificant it seems. The gears all need to be shimmed properly and the pinion gear must be set up at the right height to have a smoother sounding gearbox. Assuming that the gears inside the gearbox are all shimmed appropriately, if you hear that your gun doesn't sound very smooth when firing this could be attributed to motor height. Typically if a gun sounds high pitched and screechy out of the box, it may be that the motor pinion gear may be set too high or too low by way of motor height adjustment. The noise will come from having too little or two much contact between the pinion and bevel gears and this can cause additional wear, damage, or increased electrical load which are all bad. If you set the motor too high the gears end up binding and your gun will lock up. Repeated attempts to fire may overload your battery and damage it, as it is using an extreme amount of current to try and force the motor to turn a gear that cannot move.

About SHS

SHS is a popular brand that came on to the scene a few years ago making upgrade parts for a reasonable price. Based and manufactured in Asia, SHS parts have become popular for budget minded and professional builders alike. Airsoft techs appreciated the price while also enjoying the great quality you get for the money. You can find these parts as budget friendly repair/replacement parts or even at home in some high end guns delivering screaming performance.

If you need help or consultation on repairs you could give us a ring at (888)316-7816 or shoot us an e-mail at [email protected] . Although we only offer tech work to our local walk-in customers, we would still be happy to point you in the right direction. The senior staff and owners of the company have been playing for well over 15 years and certified and authorized by several major manufacturers to do OEM quality repair and warranty work.

Note: Fox does not warranty or accept returns for parts that have been installed/attempted to be installed.

Note: Due to varying manufacturer tolerances for gearbox internals, parts compatibility no matter what version might NOT fit even if it is supposedly correct and fitment is NOT guaranteed. The reality is that some parts may need fitting and some parts might look the same but the dimensions are slightly different enough to not work. This will require technical experience to identify to overcome.
