Automotive Lift Repair Tampa Florida | Optimizing Hydraulic Components

Loss of pressure or flow, whether gradual or sudden, leading to a power drop is often indicative of hydraulic system failure.

The issue could stem from any component in the system. The following step-by-step procedures will assist in identifying and resolving the problem efficiently:

SYSTEM INOPERATIVE

– No oil or insufficient oil: Fill the system and check for leaks.

– Incorrect oil: Refer to specifications and change the oil.

– Dirty or clogged filter: Drain the oil and replace the filter or filter element.

– Oil line restriction: Clean or replace dirty or collapsed oil lines.

– Air leaks in pump suction line: Repair or replace as needed.

– Worn or dirty pump: Clean, repair, or replace the pump, check alignment, and flush the system if contaminated oil is present.

– Badly worn components (valves, cylinders, etc.): Inspect for internal or external leakage and replace faulty components. Investigate the cause of wear.

– Leakage: Inspect all components, especially the relief valve, for proper settings and refer to technical manuals.

– Excessive load: Verify the unit’s load limits.

– Slipping or broken pump drive: Repair or replace belts, couplings, etc., and check for proper alignment or tension.

SYSTEM OPERATES ERRATICALLY

– Air in the Automotive Lift Repair Tampa Florida system: Check for leaks on the suction side and repair.

– Cold oil: Allow the oil to warm up sufficiently.

– Dirty or damaged components: Clean or repair as necessary.

– Restrictions in filters or lines: Clean and/or replace filter elements or lines.

SYSTEM OPERATES SLOWLY

– High Automotive Lift Repair Tampa Florida oil viscosity or cold oil: Allow the oil to warm up before operating.

– Low pump drive speed: Increase engine speed (refer to the manual for recommendations).

– Air in the system: Check for leaks on the suction side and repair.

– Improper adjustments: Check and adjust orifices, relief valves, etc., per the manual.

– Oil leaks: Tighten fittings and replace seals or damaged lines.

SYSTEM OPERATES TOO FAST

– Incorrectly sized or adjusted restrictor: Replace or adjust as necessary.

OVERHEATING OF OIL IN SYSTEM

– Oil passing through relief valve too long: Return the control valve to neutral when not in use.

– Incorrect, low, or dirty oil: Use the recommended oil, fill the reservoir, clean the oil, and replace filter elements.

– Excessive component internal leakage: Repair or replace the component.

– Restrictions in filters or lines: Clean and/or replace filter elements or lines.

– Malfunctioning oil cooler: Clean or repair.

– Insufficient heat radiation: Clean dirt and mud from the reservoir and components.

– Malfunctioning component: Repair or replace.

– Reservoir too small: Ensure the size is 1.5 times the pump’s GPM.

FOAMING OF OIL

– Incorrect, low, or dirty oil: Replace, clean, or add oil as needed.

– Air leaks: Check suction line and component seals for leaks and replace as necessary.

NOISY PUMP

– Low oil level, incorrect oil, foamy oil: Replace, clean, or add oil as needed.

– Plugged or undersized suction line, clogged inlet screen: Clean or replace. Follow instructions provided with the Automotive Lift Repair Tampa Florida unit.

– Use of pipe fitting in the inlet: Replace with the correct fitting.

BLOWN SHAFT SEAL

– Pump: Check for incorrect shaft rotation and replace the seal as needed. Refer to installation instructions.

– Motor: Ensure the drain line is properly connected and replace the seal as necessary. Refer to installation instructions.

LEAKY PUMP OR MOTOR

– Damaged or worn shaft seal: Replace the seal and check for misalignment.

LOAD DROPS WITH CONTROL VALVE IN NEUTRAL

– Leaking cylinder seals or fittings: Replace worn parts.

– Control valve not centering when released: Check linkage and spool binding, and repair as needed.

CONTROL VALVE DOES NOT CENTER (Binding)

– Valve linkage misaligned: Repair.

– Damaged valve: Repair or replace.

– Loose handle bracket screws: Tighten.

CONTROL VALVE LEAKS EXTERNALLY

– Tie-bolts too loose (stack valves): Tighten as necessary.

– Damaged or worn seals: Replace.

– Back pressure or restriction in tank line: Check quick couplers and use power beyond when needed.

– Cracked port or body: Replace (see Hydraulic Product Safety).

CYLINDER LEAKS EXTERNALLY

– Damaged or worn seals: Replace.

– Damaged rod: Replace.

CYLINDER LOWERS WITH VALVE IN “METER UP” POSITION

– Damaged or leaky load check: Replace the check valve.

– Leaking cylinder seal: Replace the seal.

– Valve without load check: Replace with the recommended valve.

Have you ever been tasked with troubleshooting a hydraulic issue? Whether you’re a maintenance technician, Automotive Lift Repair Tampa Florida salesperson, service provider, or consultant, it’s crucial to follow consistent guidelines for diagnosing and resolving the problem.

In many plants, troubleshooting often involves replacing parts without proper analysis, leading to costly downtime and unnecessary part expenses. Furthermore, if the machine eventually starts working again, valuable insights may be lost due to the lack of systematic troubleshooting. To effectively diagnose a hydraulic problem, follow these five steps:

1. Identify the Problem

   Hydraulic issues generally fall into two categories: pressure problems or volume problems. A pressure problem occurs when the system fails to build enough pressure to operate correctly. For instance, if a press needs 3,000 psi but only reaches 2,000 psi, it’s a pressure issue. Conversely, a volume problem involves insufficient oil delivery or bypassing in the Automotive Lift Repair Tampa Florida system, affecting speed-related issues.

   For example, a maintenance manager at a plywood plant faced a hydraulic issue with a lathe but couldn’t initially identify the problem. After gathering more information, it became clear that the issue was intermittent and related to the hydraulic motor, which sometimes stopped rotating due to a voltage drop caused by a loose wire.

2. Gather Information

   Once you’ve pinpointed the type of problem, gather all relevant information. Determine if any pressure or electrical adjustments have been made and whether any hydraulic components have been replaced. Verify that replacement parts match the original specifications exactly—small differences in part numbers can affect compatibility.

   For instance, a press in Automotive Lift Repair Tampa Florida experienced positioning issues due to a valve with a part number differing by one letter from the original. Correcting this resolved the problem. Also, check the oil level, filter condition, and for leaks, and review the latest oil analysis report for cleanliness.

   Automotive Lift Repair Tampa Florida Machine operators can provide valuable insights, as they understand the machine’s behavior and can identify changes in performance. For example, a lack of a breather cap on a reservoir caused multiple pump failures at an automotive plant.
