Hitachi Final Drive Model No

[Peter Feeny]

Hi,
The final drive packed in on me on my Hitachi ZX50u - 2.
The Part No of the final drive is KYB MAG 33vp-550F-2.

I have sources a second-hand part, but the part no. is slightly different, but the supplier says it will fit my machine. Part No Mag 33vp-650-6

Does anyone know what the digits on the code stand for ie. what does the 650 mean? The mag 33vp - 650F-6 is off a hitachi zx52 so more or less the same digger.

thanks

peter.

Would say should go straight in both models are same machine bar a few tweaks on emissions side mainly and a few years between them
