Remove point from welded tooth shank by hammering at “A” on tooth point or by driving a chisel at “B”, just between tooth point box section and tooth shank. Install new point and anchor it to shank by peening at location shown. It a tooth shank breaks off, becoming lost or damaged so that is cannot hold a tooth point, a new shank should be welded to bucket. TIGHTENING NUTS AND BOLTS Periodically check to be sure all bolts and nuts are tight (See Torque Chart). Check all pivot pins for cotter pins, washers and retainers. If any are missing, replace them. LUBRICATION Economical and efficient operation of backhoe is dependent upon regular and proper lubrication of all moving parts with a quality lubricant. All parts provided with grease fittings should be lubricated with a good quality chassis lube type grease. If any grease fittings are missing, replace them immediately. Clean all fittings thoroughly before using grease gun. Lubricate all 20 grease fittings at least twice daily (See Lubrication Chart for locations), once at the beginning of operation and again approximately half way through the work day. Grease hourly any joints that operate in water. Control valve handle linkage should be oiled with SAE 30 oil.

MAINTENANCE F-4145 01/11 Maintenance Section 5-5 HYDRAULIC TROUBLESHOOTING Hydraulic troubleshooting material presented in this section is offered as a guide to diagnosing probable causes and remedies for general operational problems. Match your problem wiht the typical problem examples given in the possible cause column. These numbers correspond with the possible cause and correction paragraphs that follow. NOTE: If, when using the following chart, it is decided that overhaul of components or pressure adjustment is necessary, it is recommended that your dealer make these repairs. He is equipped to do this work. PROBLEM POSSIBLE CAUSE Machine fails to operate when initially started. 1, 2, 5, 7, 15, 23 Machine looses power after initially operatingsatisfactorily. 1, 8, 10, 15, 23 Loss of power in lift or crowd cylinder, but other cylinders function properly 22, 24, 28 Loss of power in any one cylinder including lift andcrowd 8, 9, 10, 11, 12, 13, 22, 23, 25 Loss of power or loss of cushioning action in swing cylinders, but other cylinders function properly. 8, 9, 10, 11, 12, 13, 22, 23, 25 Maximum swing action cannot be obtained. 12, 14 Slow operation of machine (lack of power) all cylinders. 1, 4, 6, 15, 23 Spongy or jerky action of cylinders and/ or noisy operation. 1, 3, 4, 5 Lift crowd or bucket cylinders drop under load when lever spools are shifted from neutral. 26, 28 Load drops or settles. 8, 10, 13, 25, 26 Leaky cylinders. 10, 11, 12, 13 Leaky valve. 8, 15, 16, 27 Sticky valve spool. 16, 19, 20, 21 Unable to push valve spoolin. 16, 17, 20, 21 Spring centered spools do not return to neutral. 16, 17, 18, 19, 20, 21 POSSIBLE CAUSE 1 Low oil level in reservoir. 2 No oil supply to machine. 3 Air in system. 4 Oil viscosity too heavy or oil is not at operating temperature. 5 Pump not running. 6 Insufficient pumping. 7 Improper hoseconnection. 8 Loose hydraulic connections, leaks in fittings or hoses. 9 Restriction in fittings or hoses. 10 Oil is bypassingcylinder piston. 11 Scored piston rods or worn rod guides in cylinder. 12 Bent piston rod incylinder 13 Worn or damaged rod seals on cylinder. External leaks. 14 Swing linkage jammed. CORRECTIVE ACTION Fill reservoir to proper level. Engage tractor PTO. Purge all circuits of air by operating all cylinders through full movements several times. Check oil in reservoir for foaming. Check all suction lines for leaks. Fill reservoir to correct level. Use recommended hydraulic fluid. Runmachine until it reaches operating temperature. Check PTO to be sure it is engaged. Pump connected to PTO. Advance engine throttle. IMPORTANT: Be sure inlet and return hoses are hooked up correctly. Improper hookup willresult in damage tobackhoe valve. Tighten all hoseconnections and replace all damaged o-rings at leaking o-ring fittings. Check and replace any damaged hoses. Check and replace any damaged hoses and fittings. Check for pinched hoses. Replace or rebuild cylinder. Replace damaged parts. Replace or rebuild cylinder. Replace damaged parts. Replace or rebuild cylinder. Replace damaged parts Re-pack cylinder. Rebuildcylinder replacing damaged parts as necessary. Remove interference. MAINTENANCE © 2011 Alamo Group Inc. MAINTENANCE F-4145 01/11 15 Excessive back pressure. 16 Paint on valve spool. Stick...
