3623368M91 is an aftermarket swing cylinder seal kit for the Terex TX760B backhoe loader. A hydraulic swing cylinder moves the rear backhoe boom laterally during digging; it is not a loader lift, bucket, or stabilizer-cylinder kit. Replacement-kit catalogues identify this reference for a 45 mm rod and 90 mm bore cylinder. This functional detail helps distributors avoid mixing it with other TX760B cylinder kits. Order against original reference 3623368M91, which is the primary matching point for the corresponding aftermarket replacement kit.
Part Number: 3623368M91
Fits Models: TX760B
Brand: TEREX replacement
Type: Hydraulic Cylinder Seal Kit / Swing Cylinder Seal Kit
Application:
Equipment: Terex TX760B Backhoe Loader
Cylinder position: Rear backhoe swing cylinder
Function: Seals the hydraulic cylinder that swings the rear digging boom from side to side during trenching and excavation.
Backhoe Loader: TX760B
Size: Standard Size
Q1: What cylinder does 3623368M91 repair?
A: It is referenced for the rear backhoe swing cylinder on the Terex TX760B. This cylinder moves the digging boom sideways; it is not the front-loader lift or bucket cylinder.
Q2: Can this kit be used for any 45 mm × 90 mm hydraulic cylinder?
A: No. The dimensions are a useful reference check, but seal profiles and component arrangements can differ. Match the original 3623368M91 part number for the correct aftermarket kit.
Q3: Does 3623368M91 fit the Terex TX760B stabilizer cylinder?
A: No. It is listed as a swing-cylinder kit. Stabilizer, boom, dipper, bucket, and loader cylinders require their own correct seal-kit references.
Q4: Can distributors obtain a quotation by part number only?
A: Yes. Ruijueparts can match the aftermarket replacement kit directly from original reference 3623368M91. Multi-SKU purchasing lists can also be submitted for consolidated quoting and neutral or customer-specified packaging.

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.
