The car pump is noisy, no force!!!

EP.38 Loud harvest car pump

No force!!!

Pressure drop / machine no force

The pump is noisy. Howling.

The oil heats unusually fast.

Slow work. Or jerk.

There's a leak of oil, and most of the reasons are like this, found every week that users send in. 🧑‍🔧🔧

Okay, the Eaton Daikin PV23 hydraulic pump is noisy at work, so we have to look at these causes, and we have to look at them, because most of them are "going to break down" or start to lose, and I'm going to chase the unemployed guy who met.

🔊 Separate the "voice" first. Very important.

1. Howling (Weed / Wee)

🧑‍🔧 Main Principal: Air Intake / Can't Suction (Cavitation)

📌 cause.

Leaky Suction Hose / Hard O-Ring

The clamp is not tight.

Filter suction ton

Low oil levels. Check this out first.

📌 Easy check.

Look at the oil in the tank. Is there a bubble?

The sound will sound in the rush, the more it will accelerate, the more it will sound.

✅ the solution is something like this.

Chase all suction side checks (the most important)

Replacement O Ring / Screw Clamp

Wash or change the suction filter.

2. Loud "bland / heavy moan" howling moan

👉 Colonel: Inner feel pump.

📌 cause.

Piston feel

Cylinder block is a notch.

Valve plate eat this one, I think we do. Replacement parts is better.

📌 comorbid symptoms.

Hot and falling

It takes acceleration to have a force. Most acceleration is like increasing the flow rate into the system.

✅ solution

Overhall Pump

If heavy → change ball set / plate or workpiece, if we find damage, change it to waste no time on the change.

3. "Deep / banged" sound

👉 Colonel: Pressure surge / valve problem

📌 cause.

Relief valve freeze

Control valve distortion

Abnormal impact load. This one, if we don't test separately, may be difficult to discover.

📌 comorbid symptoms.

Working jerk

The pressure is not stationary.

✅ solution

Check / set relief valve

Clear the control valve.

Summary.

Pump. Hot and can't work. + Noisy.

Most 👉 will give you two digits:

Internal feel pump (very high chance)

There's air joining the system.

🔧 How to chase a professional check (recommended by order)

Open the tank lid → See oil

If there is bubble = air into ✔️

Listen to the sound when speeding around.

Howling = sucking in time

Flare = feel pump

Pressure measurement

Evening vs hot episode

If fall clear = pump is loose then

Always check the suction pipe first.

👉 Because it's the easiest and cheapest to fix.

🛠️ Solution (sorted by value)

✅ Start from: Suction Pipe Check + Filter + Oil

🔧 If not healed: Remove the overhall pump

❌ If the inner skin eats heavily: Replace the pump ball

📌 a mechanic warning.

If you still use "loud + hot"

👉 will break the set (ball + plate + housing)

👉, the repair cost will jump immediately. Very heavy damage, a new replacement will be worth it.
