Product Core Advantages
A center joint is the part most often bought twice, because the failure usually announces itself as a hydraulic fault somewhere else. When the seals inside the rotating joint pass oil, the symptoms show up as weak travel on one side, a swinging drift, or hydraulic oil appearing around the turntable - and the joint itself is the last thing checked. On the Hitachi EX and ZX families this joint carries one of the widest machine spreads of any part in the machine, and that is the trap. The same number is listed across the EX100, EX120, EX200 and the ZX200, ZX270 and ZX330 ranges, so a listing that says "EX200 center joint" tells you almost nothing about whether the joint on your machine matches. We quote against the machine model and serial, and where the joint itself carries a plate, we ask for that too. Genuine OEM and aftermarket grades are both supplied, so you can price the job at the level the machine actually warrants, and because a leaking joint is usually a seal failure before it is a body failure, we list the seal kit alongside the assembly. Each joint ships pressure tested, with every port capped and plugged.
Advantages
✓ Wide EX / ZX coverage matched to your serial, not a generic listing
✓ Genuine OEM and aftermarket grades both quoted
✓ Seal kit listed alongside the assembly
✓ Pressure tested and crated with all ports protected
