Hi
Can anyone tell me what thread the grease nipples are on my 3C3 as I have to replace a bunch.
Thanks

Although I cannot state for certain, it's a fair bet they will be 1/8" BSP thread, I doubt they would be metric but may stand to be corrected on that.

Two sizes throughout. 1/8" and 1/4" bsp. Mostly straight but there are 90 degree 1/4"s on the rod ends of the rams.

Maybe not a problem on a 3C3, but on my '87 3CX I discovered that all my grease nipples were NPT...which kinda fits with Agrimax's assessment of my serial number suggesting it was a US spec machine, despite being UK registered from new. It was not uncommon for JCB to swap machines around to fulfil big orders and/or just fit them with what they had in stores at the time
