Engine noise or knocking: Engine has not warmed up to the recommended temperature. Engine is not warmed up to the required temperature. Engine oil level is low. Add oil to the engine crankcase. Fuel injection pump timing is not adjusted. Adjust fuel injection pump as required. Broken or worn pistons. Have pistons replaced. Connecting rod is worn or misaligned. Align or change connecting rod.

Engine stops when idling: Low idle speed setting is not correct. Correct low idle adjustment. Incorrect valve clearance. Adjust valve clearance. Fuel injection pump failure. Change or repair the pump.

Low oil pressure: Low oil level. Check oil level and add oil as required. Oil pump failure. Replace as required. Oil filter is dirty. Change or clean engine oil filter element.

Boomer 41 Transmission Troubleshooting

Excessive transmission noise: Improper backlash or worn gears. Replace gears or adjust backlash correctly. Shift forks are bent or worn out. Install new shift forks. Shaft splines are stuck or worn out. Replace the shaft. Insufficient transmission oil. Need to add transmission oil. Worn or damaged bearings. Replace the bearings. Transmission fluid contamination. Fill up with fresh transmission fluid.

Difficulty shifting gears: Worn or rusty gear shift linkage. Shift linkage need to be replaced. Worn or improperly adjusted clutch. Adjust or replace the clutch. Shift forks are worn or bent. Shift forks need to be changed. Worn out parts of the gearshift mechanism. Replace worn parts.

Insufficient transmission oil pressure: Low fluid level. Need to add transmission fluid. Transmission oil filter is dirty (if equipped). Service or change transmission oil filter. Defective relief valve. Change the valve.

Transmission oil leakage: Broken seals or gaskets. Change defective seal or gaskets. High transmission oil level. Correct the oil level.

Hydrostatic Transmission Troubleshooting

HST transmission is excessively noisy: Speed control pedal linkage is damaged or out of adjustment. Repair or adjust linkage. Excessive loading. Load needs to be reduced. Insufficient oil level or contaminated oil. Change transmission oil or top up to proper level. Stuck relief valve. Replace relief valve as required. Transmission parts are worm or defective. Replace or repair defective components.

Transmission overheats: Transmission overload. Reduce loading. Cooling components are clogged or damaged. Inspect all cooling components and service or change if necessary. Lack of transmission fluid. Fill the transmission housing to proper fluid level. Dirty transmission fluid filter element. Replace or service transmission fluid filter.

Loss of power: Insufficient transmission oil. Fill the transmission housing with oil. Relief valve malfunction. Change the valve. Worn or unadjusted speed control linkage. Repair or adjust linkage.

Transmission oil leaking: Clogged oil drain line. Clean or replace drain line. Seals or gaskets are broken. Install new seal or gaskets. High internal transmission case pressure. Repair or replace damaged components.

Boomer 41 Hydraulics Troubleshooting

Excessive hydraulic system heat: Incorrect hydraulic oil type. Use the correct type of hydraulic oil. Hydraulic fluid is contaminated. Fill up with new hydraulic fluid. Air in hydraulic pipes. Bleed hydraulic pipes. Main relief valve failure. Change relief valve.

Hydraulic fluid pressure too low: Insufficient hydraulic oil. Checking hydraulic oil level and add if necessary. Clogged hydraulic fluid filter element. Replace hydraulic filter element or service if necessary. Hydraulic piping is leaking. Inspect the system for leaks and fix it. Hydraulic control valve is not set properly. Adjust properly. Hydraulic pump failure. Replace or repair hydraulic fluid pump. Faulty hydraulic cylinder. Change or repair hydraulic cylinder.

3-point hitch fails to lift or lifts slowly: Hydraulic pump failure. Install a new hydraulic oil pump. Faulty main relief valve. Change relief valve. Hydraulic control valve is faulty. Change or repair hydraulic valve. Damaged hydraulic cylinder. Install a new hydraulic cylinder or repair it. Hydraulic oil is insufficient. Need to add oil. Clogged hydraulic oil filter element. Replace filter element or clean if required. Excessive load on hitch. The load should be reduced.

3-point hitch cannot be lowered or lowering is too slowly: Hydraulic cylinder is broken. Repair or change hydraulic cylinder. Incorrect adjusted hydraulic control valve. Adjust correctly. Worn lift arm shaft. Replace the shaft. The hitch is not adjusted. Adjust as required.

Hitch lifting or lowering is jerky: Dirty hydraulic fluid. The fluid must be changed. Faulty hydraulic pump. Change or repair hydraulic oil pump. Air trapped in hydraulic system. Bleed air from system. Defective hydraulic control valve block. Repair or replace the valve. Defective hydraulic cylinder. Replace or repair hydraulic cylinder.
