Maintenance Procedures for Hause Hydraulic Power Feed Units (Models "A" and "J")

Item	Inspection	Remedy
Spindle	Condition of bearings. Test for proper adjustment - by hand.	Replace bearings or remove assembly for adjustment of nut (apply small preload with nut) by hand.
Spindle	Dry bearing resulting from excessive coolant wash or excessive high-speed.	12 months re-lubrication interval may extend life. (Push bearing spacer to one side. Fill cavity between bearings and spline tube with grease.)
Drive Shaft	Bearings - same as spindle spline.	No adjustment - tolerate some looseness. 12 months re-lubrication may extend life. (Same procedure as for spindle.)
Belted Drives	Belts - check for noise and wear.	Replace worn belts and/or tighten.
	Pulleys - should be tight run concentric.	Retighten pulleys on shafts.
	Gear reductions - look for oil leaks.	Repair or replace. Lubricate per manual instruction.
	Listen for increased noise level from gears and bearings.	Replace and/or lubricate.>
