KB20121-31101 RING,L.H. (KIT) Komatsu FB10/14EX-8 Forklift
Overview
The Komatsu KB20121-31101 RING,L.H. (KIT) is a left-hand ring kit used in Komatsu electric counterbalance forklifts, including the FB10/14EX-8, FB10M-3, FB13M-3 and FB15/18EX-8 model families. Supplied as a complete kit rather than a single loose component, it gives technicians the ring and accompanying small parts needed to carry out a proper replacement in one service visit.
Because KB20121-31101 is an original Komatsu part number, this kit matches the dimensions, tolerances and material specifications Komatsu defined for these trucks. Fitting the correct left-hand ring kit helps restore proper clearances and keeps the affected assembly working as the manufacturer intended — an important consideration on electric trucks, where unplanned downtime directly impacts warehouse productivity.

Installation and Maintenance Tips
- Verify the model and serial number on the truck nameplate against the application list above.
- Compare the removed ring with the new kit before installation to confirm orientation — this is a left-hand (L.H.) component, so check whether the matching right-hand side shows similar wear.
- Follow the relevant Komatsu service manual for removal, cleaning and torque specifications.
- Inspect related hardware and mating surfaces while the assembly is open, and replace any parts showing scores, distortion or excessive wear.
- Record the replacement in your maintenance log to support future servicing decisions.
