My Kubota FL850 driveline痴 universal joints is Kubota part # 70710-61340. Crazy priced from Kubota and other suppliers. Mine had a KC 1518 (25mm-58mm) in it. Where 58mm is the outside dimension. Based on dimensions, it crosses over to a Moog 397 universal joints ( u-joint ). It uses cap sized at 0.985 (~25mm) and clip spacing (inside yoke) of 1.717?
If the drive line yoke holes are slightly stripped out there is Moog 514g, that has Cap sized at 1.000 and clip spacing of 1.719?
I just changed one with the Moog 397 and it fits just fine. No more crazy driveline universal joint wobble.
