Does anyone know the bucket pin dimensions for a 2003 JD 120C?

[Marcus Marcus]

I'm trying to find the bucket pin dimensions for a 2003 John Deere 120C. I need the pin diameter, ear-to-ear width, and center-to-center pin spacing. From what I've found, Deere 490 buckets may fit, and the pin diameter appears to be 65 mm with a 255 mm ear-to-ear width. I'm just missing the center-to-center measurement.

Does anyone know the correct dimensions or a good reference for this information?

If it's the original bucket, the pin size can vary depending on the bucket and coupler. Checking the bucket serial number or measuring the existing pins is usually the most accurate way to get the correct dimensions.

Yep — for the JD 120C, standard bucket pin specs are:

Pin diameter:65mm (both stick and H-link side)
Bucket ear-to-ear width:254–255mm (~10 in)
Pin center-to-center: 362mm (~14¼ in)

Same specs apply across 120C, 120D, 130G, 135C RTS, 135D, and 135G, so buckets swap freely between those. Also cross-compatible with several Hitachi EX100/120/Zaxis 120-135, Case CX130/135SR, and Link-Belt models if you're shopping used buckets.

Classic excavator problem — no industry standard, every brand does its own thing on pin spacing.

I think the center-to-center spacing is around 362 mm (14.25"). Hopefully someone with a 120C can confirm from a machine measurement. Good luck!

Hi! I checked the available information, and the bucket pin diameter is commonly listed as 65 mm with an ear to ear width of 255 mm. However, I haven't been able to confirm the center-to-center pin spacing.

If anyone has a 2003 John Deere 120C or access to the parts manual, could you please share the center-to-center measurement? It would be greatly appreciated. Thanks in advance!
