STEP ONE: Remove the PTO shield on the tractor. The PTO shield is held onto the tractor differential housing with four nuts on the inside of the shield.
STEP TWO: Slip the bracket over the four bolts that held the PTO shield onto the tractor and fasten using 10mm washers and nuts.
STEP THREE: Tighten the four bolts to a torque setting of 45 ft. pounds of torque.
STEP FOUR: Mount PumpDoctor body to brackets using carriage bolts facing rearwards with a flat washer, lock washer, and nut.
STEP FIVE: Apply grease to PTO shaft. Install the tractor sprocket #1 on to the PTO shaft, sliding it all the way forward.
STEP SIX: You are now ready to install the pump. Several pieces of wood blocking and a prybar will be helpful for installing the heavy pump.
STEP SEVEN: Slide sprocket on to pump shaft as it is inserted through body. Use bolts, lock washers & nuts, and secure the pump to the faceplate.
STEP EIGHT: After you have the pump mounted to the PumpDoctor body, make sure the chain coupler sprockets are aligned. If not, pry or tap to correct as needed.

Remove the PTO shield on the tractor. The PTO shield is held onto the tractor differential housing with four nuts on the inside of the shield.
Slip the bracket over the four bolts that held the PTO shield onto the tractor and fasten using 10mm washers and nuts. There are two clips that hold the top plate on the PTO shield and two washers on the bottom bolts. Take these off and store them so you will have them when you take the PumpDoctor off from the tractor and reinstall the shield.
Tighten the four bolts to a torque setting of 45 ft. pounds of torque. You will need an extension and deep socket inserted through access holes in rear of bracket to tighten these.
Mount PumpDoctor body to brackets using carriage bolts facing rearwards with a flat washer, lock washer, and nut. Tighten bolts slightly past hand-tight. This will allow prying body or tapping with dead-blow hammer to align sprockets correctly.
Apply grease to PTO shaft. Install the tractor sprocket #1 on to the PTO shaft, sliding it all the way forward.
You are now ready to install the pump. Several pieces of wood blocking and a prybar will be helpful for installing the heavy pump.
Slide sprocket on to pump shaft as it is inserted through body. Use bolts, lock washers & nuts, and secure the pump to the faceplate. You can tighten the four bolts at this time. Torque to 80lb ft. Make sure pump sprocket is flush with end of shaft, then apply a drop of removable Locktite to each of the two set screws and tighten firmly.
After you have the pump mounted to the PumpDoctor body, the chain coupler sprockets should look like the picture above. Make certain they are aligned. If not, pry or tap to correct as needed.
Wrap chain around the sprockets. Insert connector link. Recheck alignment. Chain should be able to be slid back and forth on sprockets at top, sides & bottom.
Tighten carriage bolts to 80lb ft. once alignment is double checked. Your complete unit should look like the picture above if everything is installed correctly. Chain should be lubricated twice daily with chain lube.
