Lubrication of shearing pump
1 Bearings lubrication:

Add a good grade of 10W30 weight motor oil until the middle level of dipstick. Don not overfill the oil. High levels may cause churning and overheating of the bearings. Oil should be changed every 90 days or 1000 hours.

2 Stuffing box lubrication

The stuffing box may be re-lubricated with grease as often as necessary to prevent the packing from overheating. It should be lubricated at least once a day.

Maintenance
All parts should be clean before assembly. This is especially important for O-ring grooves, threads, gasket surfaces, bearings and bearings surfaces. Any burrs should be removed with crocus cloth.

Firstly slip the bearings onto the shaft. The two bearings are to be mounted back-to-back(that is, sides of the bearings with the manufacturer’s name and the bearing number are placed together), with lock washer in place tighten locknut with the bevel positioned against the bearings tighten the locknut to 346m/1N of torque. Then, put the with bearings into the frame from left and slip the bearing onto the shaft from right of frame.
