Direct Replacement Undercarriage Parts for Dozers Minor Bogie Pins and Heavy-Duty Caps
Features
Forged 40Mn2/40Cr Steel: We don't use casting for these critical components. Everything is forged to handle the constant oscillation and impact of D8/D10/D11 sized dozers.
Deep Induction Hardened Pins: The Bogie Pins feature a 3mm-5mm hardened case depth. This ensures the core stays tough while the surface resists the friction of metal-on-metal contact.
Leak-Proof Sealing: Our Track Roller and Idler Caps are machined for a perfect seat with floating seals, keeping the oil in and the mud out during high-hour operations.
Strict Tolerance Control: Every Bogie Pin is precision-ground to microns. This means no "hammering" to get it to fit—it slides right into the minor bogie bore for a clean install.
