2386312301, 238-63-12301 CYLINDER ASSY KOMATSU

Heavy-Duty Blade Lift Cylinder Assembly for Komatsu Motor Graders

The 2386312301, 238-63-12301 CYLINDER ASSY KOMATSU is a hydraulic blade lift cylinder assembly used in Komatsu motor grader applications. Public parts references identify 238-63-12301 as CYLINDER ASS’Y, BLADE LIFT, and available catalog-style sources connect it with Komatsu grader hydraulic systems, especially blade lift cylinder lines.

For a motor grader, the blade lift system is one of the most important working functions. The blade must rise, lower, and hold position accurately during road construction, shoulder shaping, drainage preparation, base leveling, and fine surface finishing. When the lift cylinder becomes weak, worn, leaking, or damaged, the grader may lose the smooth control that operators need for consistent surface quality. That is why buyers usually search directly for 2386312301 or 238-63-12301instead of using only broad terms such as “Komatsu hydraulic cylinder.”

At 3GEN Export, we supply 2386312301, 238-63-12301 CYLINDER ASSY KOMATSU as an OEM supplier solution for global heavy machinery buyers. We deliver all over the world in 5 working days, helping contractors, workshops, resellers, and fleet owners reduce downtime and keep Komatsu graders ready for work.

What Is 2386312301, 238-63-12301 CYLINDER ASSY KOMATSU?

The 2386312301, 238-63-12301 CYLINDER ASSY KOMATSU is best described as a Komatsu grader blade lift hydraulic cylinder assembly. UrParts lists 238-63-12301 as CYLINDER ASS’Y, BLADE LIFT under Komatsu grader parts for GD611, while a 3gen catalog page for GD621R-1 hydraulic piping lists 238-63-12301 CYLINDER ASS’Y with a weight reference of 55 kg in the blade lift cylinder line section.

This means the part should not be positioned as a steering cylinder, leaning cylinder, or general-purpose hydraulic actuator. It is a function-specific blade lift cylinder assembly for Komatsu grader applications. A separate seal kit listing also describes 238-63-12301 as a blade lift cylinder assembly seal kit for Komatsu graders GD505A and GD521A, which supports the same functional classification.

Why This Komatsu Blade Lift Cylinder Matters

A grader’s value comes from precision. Unlike machines used mostly for rough pushing or digging, a grader must shape surfaces with controlled blade movement. The blade lift cylinder directly affects how the blade rises, lowers, and holds its working height.

When 2386312301, 238-63-12301 CYLINDER ASSY KOMATSU performs properly, it helps the operator maintain accurate blade height and smoother hydraulic response. When the cylinder fails, the machine may show oil leakage, weak lift performance, blade drift, uneven blade movement, or loss of control during fine grading.

That can affect:

Road Surface Quality

A weak blade lift cylinder can make it harder to keep the cutting edge at the correct height, especially during finishing passes.

Operator Control

A strong and stable cylinder helps the operator make precise blade adjustments without constant correction.

Machine Productivity

If the blade cannot lift or hold properly, the grader may need extra passes, slowing down the job.

Maintenance Downtime

Replacing a worn cylinder assembly can be faster and more practical than repeatedly repairing a heavily damaged unit.

Blade lift cylinder assembly for Komatsu graders.

Public listings identify 238-63-12301 as a blade lift cylinder assembly, and seal kit listings also support the blade lift application for Komatsu graders.

Related Service Details

A hydraulic seal kit reference for this cylinder family lists Blade Lift, rod 50 mm, and bore 80 mm for Komatsu motor grader applications. This is useful for workshops because it gives a service clue for the cylinder family, even though the complete cylinder assembly itself should still be verified by part number and machine serial number.

Weight in KG

The 3gen catalog-style weight reference found for 238-63-12301 is 55 kg, listed in a GD621R-1 blade lift cylinder line catalog page. Another parts listing from Serwis-Kop appears to show the number 45800, which likely means 45.8 kgin their weight format. Because sources vary, the safest product-page wording is:

Estimated product weight: 55 kg

For export quotation, final packed weight should still be confirmed by warehouse scale before shipment.

Important Fitment Note

Final compatibility should always be confirmed by exact part number, machine model, and serial number before purchase. Komatsu grader hydraulic components can vary by production range, regional configuration, and cylinder line. This is especially important because closely related numbers such as 238-63-12302, 238-63-12320, and 238-63-12340 may appear in the same blade lift cylinder family.

Product Design and Working Characteristics

The product image shows a long yellow hydraulic cylinder body with a mounting end, side porting, and a blade-lift-style structure suitable for grader hydraulic use. This visual profile aligns with the public identification of the part as a blade lift cylinder assembly.

A blade lift cylinder works under repeated hydraulic pressure, vibration, dust, and outdoor exposure. It must support controlled movement, stable holding power, and reliable sealing. In grader work, the cylinder is not used only occasionally; blade height adjustments can happen constantly during road finishing and leveling.

Controlled Vertical Blade Movement

The cylinder helps raise and lower the grader blade with hydraulic force.

Stable Blade Holding

A strong blade lift cylinder helps the blade stay in the selected position during operation.

Serviceable Hydraulic Family

Seal kit listings for the same cylinder number show that this blade lift cylinder family is recognized in the hydraulic repair market.

Grader-Specific Application

Because public sources identify the part as a blade lift cylinder for Komatsu graders, it should be presented as a grader-specific hydraulic component, not a universal industrial cylinder.

Key Benefits of 2386312301, 238-63-12301 CYLINDER ASSY KOMATSU

Supports Accurate Blade Height Control

The cylinder helps the operator raise, lower, and hold the blade at the required working height.

Helps Restore Hydraulic Performance

Replacing a worn or leaking cylinder can restore smoother blade movement and reduce hydraulic instability.

Improves Grading Consistency

Better blade lift control helps the grader maintain a cleaner and more consistent working surface.

Reduces Repair Delays

A complete cylinder assembly can be a practical solution when the old unit has serious rod, barrel, or sealing damage.

Strong Search Visibility

Using both 2386312301 and 238-63-12301 helps your product page appear for buyers searching in different part-number formats.

Common Reasons for Replacement

Hydraulic Oil Leakage

Seal wear can cause external leakage and pressure loss. Seal kit listings for this cylinder number confirm that sealing maintenance is a known service need.

Weak Blade Lift Response

If the blade lifts slowly, drops under load, or does not hold position, the cylinder may be internally worn.

Rod or Barrel Damage

Bent rods, scored surfaces, corrosion, or impact damage can make complete assembly replacement more reliable than repair.

Fleet Refurbishment

Used graders prepared for resale, export, or continued fleet service often need hydraulic cylinder inspection and replacement.

Preventive Maintenance

Replacing a weak blade lift cylinder before total failure can help avoid downtime during roadwork and grading operations.
