60160568 O‑ring – Critical Sealing Component for SANY PTO Shaft Assembly

The O‑ring with OEM number 60160568 is a vital sealing component used in the SANY PTO (Power Take‑Off) Shaft Assembly for D09, D12, D13, WP12, and WP13 engine applications.

It provides a static fluid seal between the PTO shaft housing, flange, and the adapter block (160102120008A059), preventing oil leakage from the power take‑off unit and keeping contaminants out of the lubrication system.

The SANY PTO Shaft Assembly is a precision‑engineered power transmission component that transfers torque from the engine to auxiliary equipment such as concrete pumps, mixers, and other powered attachments.

Within this assembly, multiple O‑rings (including 60160568) are installed in machined grooves on the housing flange and the adapter block, creating a leak‑proof barrier under oil pressures up to 10 bar.

The PTO shaft is supported by durable Bearing, Cylindrical Roller (169900000095A) and secured by Ring, Retainer, Elastic (169900000097A), while the 60160568 O‑ring ensures all fluid passages remain sealed during operation.

The O‑ring is manufactured from premium nitrile rubber (NBR) with a hardness of 70 Shore A, providing excellent resistance to petroleum‑based oils, diesel fuel, and coolant.

The material formulation meets ASTM D2000 standards (Line Callout M2BG 710 A14 B14 C12 F17), ensuring consistent performance across all SANY applications.

The O‑ring has a typical cross‑section diameter of 3.53 mm (AS568‑2xx series) with an inner diameter matched to the specific groove dimensions of the SANY adapter block and housing.

Every genuine 60160568 O‑ring is 100% inspected for dimensional accuracy, flash removal, and surface defects using automated optical systems.

A compressed or damaged O‑ring will allow oil to leak past the flange, resulting in visible fluid loss, reduced lubrication pressure, and potential bearing seizure.

Why Genuine SANY 60160568 O‑ring Is Superior to Aftermarket Seals

Compatibility – SANY Equipment Using 60160568 O‑ring

The 60160568 O‑ring is compatible with SANY D09, D12, D13, WP12G460E50, and WP13G500E30 diesel engines used in Actlon 6×4/8×4 tippers, SY331, SY412, SY425 mining dump trucks, SYM3310 series, concrete mixer trucks, concrete pump trucks, wheel loaders, motor graders, and STC truck cranes.

Within the SANY PTO Shaft Assembly, this O‑ring provides a static seal between the adapter block (160102120008A059) and the PTO housing flange, preventing oil leakage at the bolted joint interface.

The PTO Shaft Assembly also includes Bearing, Cylindrical Roller (169900000095A), Ring, Retainer, Elastic (169900000097A), Ring, Spacer (169900000101A), and multiple fasteners (Inner Hexagon Socket Head Cap Screws 160102120008A055, Screw, Socket Head Cap 61005491).

The Flange (160102120008A057) and Housing (160102120008A060) are also sealed with this O‑ring to ensure complete fluid containment within the power take‑off unit.

This O‑ring is designed for static sealing applications only, with a recommended groove fill of 70–80% for optimal sealing performance.

Proper sealing is essential for maintaining oil pressure within the PTO shaft, ensuring adequate lubrication of bearings and gears, and preventing environmental contamination.

Installation Guide for O‑ring 60160568

O‑ring replacement should be performed by qualified technicians following the SANY service manual for the specific equipment model and PTO shaft assembly.

Before removal, ensure the equipment is powered down, the PTO shaft is stationary, and the system has been depressurized to prevent sudden oil release.

Drain the oil from the PTO housing or position the assembly to minimize fluid spillage during seal replacement.

Remove the flange or adapter block bolts to access the O‑ring groove. Carefully separate the mating components to avoid damaging the sealing surfaces.

Remove the old O‑ring using a plastic or brass tool – never use metal tools that could scratch the sealing groove or mating surfaces.

Clean the O‑ring groove and the mating flange surface thoroughly with a lint‑free cloth and degreaser, removing all old seal material, oil, and debris.

Inspect the groove for burrs, scratches, or corrosion that could damage the new O‑ring or prevent proper sealing.

Lubricate the new 60160568 O‑ring with clean engine oil or a compatible assembly lubricant before installation to prevent twisting or pinching during assembly.

Install the O‑ring by gently stretching it over the flange or into the groove – do not force it or use excessive elongation.

Ensure the O‑ring sits evenly in the groove without twisting or overlapping. It should be slightly proud of the groove surface by 0.2–0.5 mm for proper compression.

Reassemble the mating flange or adapter block, tightening the bolts in a star pattern to the specified torque (typically 25–35 Nm for M8 bolts, consult service manual).

After assembly, refill the PTO housing with the specified SANY lubricant and run the unit at idle, checking for any oil seepage around the flange joint.

If a leak is detected, re‑torque the flange bolts; if leakage persists, replace the O‑ring again, checking for groove damage or improper installation.

Never reuse an old O‑ring that has been removed – it will have taken a compression set and will not seal properly.

Always replace the O‑ring whenever the PTO shaft is serviced, or if any leakage is observed during routine inspections.

Use only genuine SANY O‑rings to guarantee correct material, dimensions, and long‑term sealing performance for your heavy‑duty equipment.
