Duty, media and the stamp on the worn piece
Construction and plant parts are specified from media, duty cycle and the OEM mark on the worn piece. A bucket tooth, a hydraulic hose, a knife gate and a track pad can all 'look close' and still be the wrong steel, thread or face-to-face. This pillar is the hub for identifying wear parts, chasing hydraulic leaks, and specifying undercarriage and ground-engaging tools before the machine sits through another shift.
A 322 tooth, a 16 mm 2SN hose and a PC210-8 sprocket are three quotes. Compare SRC-CS-T322, SRC-CS-H16 and SRC-CS-SP210 so a photo of 'the broken bit' becomes a named SKU.
Duty first: abrasive, impact, pressure, media
Quarry, demolition, road building and farm slurry are not one spec. Abrasive sand wants a different tooth and cutting edge than impact in demolition. A slurry valve wants a seat compound the grain line does not. Hydraulic hoses are pressure, temperature and bend radius, not only length and dash size. Write the duty on the requisition so purchasing is not guessing from a photo of mud.
Copy the mark, then the machine
Make and model matter for brackets, pin diameters and hose routing that were unique to that serial range. The OEM stamp on the tooth, adapter, valve body or hose ferrule still wins when the published fit list is thin. Photograph the mark, the pin, and the adjacent casting. Construction-parts listings are the start when the machine is known; the stamp is the start when it is not.
Do not isolate the failed piece
A leaking hose is often a failed clamp, a too-tight bend or a coupler that was never to spec. A tooth that will not stay in is an adapter, not only a pin. A valve that scores on day one still has solids in the chest. The cluster articles treat leaks, wear identification and undercarriage as systems so the next order includes the parts that actually caused the stoppage.
- Write media, pressure and duty on the job card
- Photograph OEM marks, pins and adjacent castings
- Replace the cause (adapter, clamp, seat) with the visible part
- Use model search when the category fit list is incomplete
Pins, threads and face-to-face
A tooth that almost pins will walk. A hose that is the right dash size with the wrong thread will weep from the first shift. Valve bodies are face-to-face and flange standard, not 'a six-inch gate'. Measure pins. Copy the thread from the ferrule, not from memory. If two machines on the yard share a colour and not a pin diameter, write both serials on the requisition so purchasing does not average them. Construction-parts listings help when the machine is known; the stamp is the start when it is not.
When the published fit list is empty
A thin catalogue is not a reason to guess from mud colour. Photograph the mark, the pin and the adjacent casting, then send media, pressure and abrasive-versus-impact duty with the make and model. Do not cannibalise a second machine for a 'close' tooth that belongs to another adapter family. SEROC quotes B2B from that pack — no webshop account is required. Quarry, demolition and farm slurry can share a yard and not share a seat compound or a tooth steel.
What to read next
Knife-gate selection is media, flanges and fail position. Wear-part identification is suffixes and pin sizes, not 'a standard tooth'. Hydraulic leaks are diagnosis before hose length. Undercarriage and ground-engaging tools are wear matching left to right and front to rear. Bearings on dirty plant follow the same contamination rules as harvest equipment. Measure pins. Match left and right undercarriage wear before you buy one sprocket.
How SEROC quotes construction parts
Write media, pressure, abrasive-versus-impact duty, make, model and the OEM mark on the worn piece. Photograph pins and adjacent castings when the suffix is hard to read. A quarry tooth, a slurry valve and a hydraulic hose can share a yard and not share a spec. Do not send only a bucket photo. Browse construction-parts when the machine is known; use model search when you only have the serial. The cluster pages under this pillar split the job: knife gates, wear identification, hydraulic leaks, and undercarriage as a set. Bearings on dirty plant follow the harvest-equipment contamination rules on the bearings article.
Why a rusty piece is still the spec
Mud hides suffixes. Clean the mark before you photograph it. A tooth, a hose ferrule and a valve body all carry the identity that the machine colour does not. If purchasing is guessing from a competitor screenshot, stop and copy the stamp. Face-to-face, pin diameter and thread are cheap to measure and expensive to get wrong at the port. SEROC will quote from that pack even when the construction-parts grid is still thin. Do not hold the machine for a lookalike from another family 'to keep it working' — adapters and seats fail faster than the freight. Help Centre covers what to send on the first email so this pillar stays a specification hub.
