Toyota Skidsteer 2SDK8 12301 pins and bushing specifications

There's no published dimension table for 2SDK8 pins and bushings floating around online, and that's a known pain point on this model. Other 2SDK8 owners hunting the same numbers asked for pins and bushing specs for a Toyota 2SDK8 skid steer and were told it was cheaper to have the pins machined locally than to order them from a parts source, and one owner going through a full rebuild finished a rebuild on a 2SDK8 involving making up new pins and bushes and seal kits through the lift and curl cylinders, then went looking for a manual rather than finding published specs first. So the realistic path on a 40-year-old Toyota is measure-and-match, not look-up.

Practical approach at 4600 hours with play in the bucket and lift arms:

1. Pull each pin and mic it in three spots (each end plus center) with calipers. Uneven wear (hourglassing) tells you the bushing is shot even if the pin still reads near nominal; wear concentrated at one end points to a bent pin or misaligned boss.
2. Mic the bushing ID the same way, and check the housing bore it presses into for elongation, on these skid steers bucket bushings wear faster than lift arm bushings from cycling load, matching the pattern.
3. Use those actual measured dimensions to have new pins and bushings turned locally, this is exactly what the machine owners quoted above ended up doing since dealer sourcing through Toyota Material Handling Japan is slow and parts availability is inconsistent.
4. If you want factory dimensions before cutting metal, a Toyota Material Handling dealer can pull them from the parts system by serial number (12301), since these skid steers share parts lineage with Toyota forklifts of the era.
5. Standard fits: pin to bushing running clearance typically comes in around 0.05-0.15mm on this size and class of construction equipment pin, and bushing to housing is normally a light press fit, verify actual class fit off your old components before cutting, don't assume this without checking your removed parts since Toyota may have used a tighter or looser tolerance band than typical.

Post your measured pin/bushing diameters (or better, photos with calipers on them) and I can help you sanity check whether what you're seeing is normal wear or something has been running dry.
