61QB-31310 Tiger Point Bucket Tooth for Hyundai Excavators

Full Description

The 61QB-31310 is a replaceable excavator bucket tooth identified in Hyundai parts references as a POINT-TOOTH, TIGER and by an official dealer as a TOOTH POINT (ROCK-TIGER). This product is supplied as an aftermarket replacement for selected rock-bucket and tiger-tooth bucket assemblies used on large Hyundai crawler excavators.

The photographed tooth has a broad wedge-shaped working end, a raised central rib and an enlarged socket at the rear. A side opening near the socket forms part of the tooth-retention arrangement. The upper surface carries the raised part number 61QB-31310. The photographed sample has a yellow-painted finish. No Hyundai trademark is visible on the product itself.

During installation, the tooth fits over a matching adapter attached to the bucket cutting edge. Parts catalogues commonly associate the 61QB-31310 tooth with adapter reference 62NB-31320, pin reference 66NB-31340 and lock-washer reference 66NB-31350. These related components must be checked against the actual bucket and are not assumed to be included with the tooth.

Documented applications include selected rock or tiger-tooth bucket configurations on Hyundai R450LC-7A, R480LC-9, R500LC-7A, R520LC-9S and HX520L excavators. Additional parts directories associate the number with R450LC-7, R500LC-7, R480LC-9A, R480LC-9S, R520LC-9 and R520LC-9A machines.

These model references do not indicate universal compatibility. The same excavator model may use a different tooth depending on bucket capacity, bucket assembly number, machine serial number and working configuration. Related teeth such as 61QB-31310BG, 61QB-31310G9 and 66NB-31310GG may appear in alternative bucket assemblies and should not be treated as automatically interchangeable.

The tooth is intended for excavation and loading where the specified rock or tiger-tooth bucket system is installed. Actual material, weight, hardness, heat treatment and manufacturing process should be confirmed from the supplied product specification.

For compatibility checking, provide the full machine model, serial number, bucket capacity, existing tooth marking, adapter number and clear photographs of the mounting system. If the old part number is unavailable, dimensioned photographs or a physical sample may be used for identification.
