The 800167102 Screw With Sealing Washer, cross-referenced as 3011715, is an OEM replacement fastener for XCMG hydraulic excavators. It combines a threaded screw with an integrated sealing washer for a tight, leak-resistant joint.
This screw is produced from high-strength steel with a protective finish. The attached sealing washer is made from a resilient, fuel-resistant and coolant-resistant material that compresses evenly under load.
The 3011715 screw is precision-formed to match the original thread pitch, head size and washer diameter. It fits the factory tapped hole and seals against the mating surface without extra washers or sealant.
On an excavator, this type of screw is used at fluid connections and covers where both clamping force and sealing are needed. A worn or damaged screw can cause leaks, loose panels or fluid seepage.
Common replacement signs include a damaged screw head, stripped threads, a hardened or cracked sealing washer, fluid stains around the joint and a fitting that will not tighten properly.
Fitting a new 800167102 screw restores correct clamp load and a clean seal at the joint. This helps prevent leaks, protects the surrounding parts and keeps the machine working reliably.

A screw with a sealing washer performs two jobs at once. It clamps two parts together and seals the joint against fluid or dust. This makes it useful at covers, fluid connections and access panels.
On an excavator, joints are exposed to vibration, heat, mud and water. The 800167102 screw must hold its clamp load and keep the sealing washer compressed through long working shifts.
The 3011715 screw is shaped to match the original thread and washer seat. This supports correct tightening, even compression and a clean seal without additional sealant.
A worn screw or hardened washer can allow fluid to seep past the joint. This may cause stains, low fluid level, dust ingress and corrosion around the connection.
Replacing the screw during service is a low-cost preventive step. It avoids a second repair later and protects the surrounding parts from leak damage.
Keeping the joint clean and the washer fresh supports reliable sealing and helps the machine stay free of fluid leaks in daily excavation work.
The screw is built for strength, correct fit and reliable sealing. The main features are listed below for quick comparison.
The 800167102 Screw With Sealing Washer is intended for XCMG hydraulic excavators with the matching thread and sealing layout. It fits the original tapped hole and mating surface.
The 3011715 cross-reference covers XCMG machine platforms that use this fastener size. This makes the screw suitable for maintenance and repair on compatible excavator models.
Typical use includes general excavation, trenching, loading, site preparation and utility work. These jobs demand reliable fasteners that stay tight under vibration and load changes.
Always confirm the OEM number and thread size before fitting. The 800167102 part is a direct replacement for the matching position and keeps the joint close to factory specification.
Park the excavator on level ground, lower the attachment and switch off the engine. Allow hot parts to cool and relieve any fluid pressure before opening the joint.
Clean the area around the screw to keep dirt out of the joint. Remove the old screw with the correct tool and inspect the threads and sealing surface for damage.
Fit the new 800167102 screw with a clean sealing surface and tighten to the workshop torque value. Avoid over-tightening, which can damage the washer or strip the threads.
Check for leaks or looseness after the machine reaches working temperature. During routine service, inspect the screw and washer for corrosion, cracks or compression set.
The 800167102 screw is produced to match the original thread and sealing dimensions. Thread pitch, head size and washer diameter are checked for correct fit.
The steel body and protective coating help resist rust and wear. This is important for excavators that work outdoors and are exposed to mud, water and dust.
Each batch is inspected for surface quality, thread condition and washer integrity. Batch checks support consistent fit and help reduce installation time in the workshop.
A correct screw protects the joint from leaks and loosening. This supports stable clamp load and helps avoid fluid loss and corrosion around the connection.
A worn screw can seem like a small problem, but it can allow a joint to loosen and leak. Ignoring it may cause fluid loss, dust ingress and damage to surrounding parts.
The 800167102 replacement screw offers a direct fit, high-strength steel body and an integrated sealing washer. It is designed for the practical demands of XCMG excavators in earthmoving work.
For maintenance teams, stocking this screw number helps reduce waiting time when a fastener fails. It supports planned service and quick replacement.
Choose the 800167102 3011715 Screw With Sealing Washer for correct clamp load, reliable sealing and dependable performance on compatible XCMG excavators. Confirm the OEM number before ordering.
