VOE12724304 is an aftermarket seal-kit reference for selected Volvo motor grader cylinders. Circle-turn applications are catalogued for 750A and 780A graders with cylinder 89011, making the cylinder reference a useful starting point for buyers maintaining older equipment. Check the machine serial number before ordering rather than relying on the model name alone. If the original cylinder has been replaced or modified, Ruijueparts offers custom seal support for older machines, subject to review of samples or dimensions.
Part Number / SKU: VOE12724304
Reference Number: 12724304
Supplier: Ruijueparts
Compatible Equipment Make: Volvo
Product Type: Circle Turn Cylinder Seal Kit
Manufacturer Type: Aftermarket
Condition: New
Equipment: Motor grader
Catalogued Models: 750A, 780A
Cylinder Position: Circle turn
Cylinder Reference: 89011
Function: Operates the circle-turn mechanism to adjust blade angle during grading.
Fitment Check: Match the original seal-kit reference, installed cylinder and machine serial number. Model identification alone is insufficient.
Q1: What cylinder is VOE12724304 used for?
A documented application is the circle-turn cylinder on selected Volvo 750A and 780A motor graders, identified by cylinder reference 89011. Confirm the serial-number coverage before purchase.
Q2: Will this fit any G700 or G900 series grader?
Do not order on the series name alone. A broad model-family listing does not confirm the cylinder fitted to your machine. Send the full model, serial number and cylinder reference so the application can be checked.
Q3: My older grader has a replacement cylinder. Can I still order by the machine model?
The installed cylinder should be identified first because it may differ from the original assembly. If the standard reference cannot be confirmed, Ruijueparts offers custom seal support for older equipment. Provide cylinder details, seal samples or dimensions for review; feasibility must be confirmed before ordering.
Q4: Can I substitute VOE12724306 for VOE12724304?
Do not treat them as substitutes. They are separate seal-kit references with different catalogued cylinder dimensions and applications. Match the kit to the installed cylinder rather than choosing by similar part numbers.

OEM seal kits are the right choice when machinery is under active warranty, operating at peak duty cycles, or when failure risk is unacceptably high. Budget aftermarket—like Ruijue Parts—makes sense in these common scenarios:
When a machine is aging out of your fleet, OEM parts cost more than the job warrants. A budget kit extends service life without over-investing.
For machines used infrequently or on lower-intensity tasks, premium OEM pricing may not be justified.
When OEM stock is out or delivery takes weeks, an available aftermarket kit gets your machine running now.
Repair shops and fleet managers running high volumes of machines often balance OEM and aftermarket across their portfolio based on criticality.
Fully retract the cylinder and relieve system pressure before disassembly. Never work on a pressurized circuit.
Remove from the machine. Unthread the gland nut and withdraw the piston rod carefully to avoid surface damage.
Clean the bore, rod, and all metal parts with a lint-free cloth. Contamination introduced during reassembly accelerates seal wear—this step is especially important for budget-grade seals.
Check for scoring or pitting. Budget seals are more sensitive to surface imperfections—address rod damage before fitting new seals.
Lightly coat each seal with clean hydraulic fluid before installation. Use proper seal drivers — not screwdrivers or sharp tools — to avoid nicking the sealing lip.
Torque the gland nut to spec and cycle the hydraulic system under no-load conditions. Inspect for leaks before returning the machine to service.
Budget-grade seals may have shorter service intervals than OEM. Inspect rod seals for moisture, oil film, or weeping more frequently and replace proactively.
Contaminated fluid degrades seals faster — this applies especially to non-OEM materials. Replace fluid and filters on schedule.
When storing equipment with cylinders extended, protect rod surfaces from corrosion and debris to preserve wiper seal life.
Avoid using sharp tools during assembly to prevent nicks or scores on the seal lips. Pre-lubricating all components with clean hydraulic oil is recommended to ensure a smooth fit into the cylinder grooves.
