Making NEW Pins for Earthmoving Machinery | Machining & Welding

These pins are worn out so we are making new replacement pins! We’ve got 2 big bucket pins from a Hitachi ZX670 Excavator and 2 pins from the ripper bed frame off a D9T Bulldozer. We show the step by step process of making the new pins. We start with machining the plates off the old pins before machining up the new pins using induction hardened chrome rod. The D9 dozer pins also need deep hold drilling and tapping for the grease holes before using the milling machine to drill a through hole for the grease channel. We finish up the job by welding the plates onto the new pins.

In this video we are using:
- Hafco TM-26120G Centre Lathe
- Hafco BM-63VE Milling machine
- WIA 500i Weldmatic welder
