333/D8456 LHS Bucket Side Cutter – JCB 400/F0343 Replacement

The 333/D8456 bucket side cutter is an aftermarket left-hand replacement for selected JCB-compatible backhoe-loader and mini-excavator buckets. JCB parts records identify 400/F0343 as the current replacement reference and associate earlier references including 332/C4389, 531/03207 and 531/03209 with the same LHS position.

Its asymmetric, extended side profile protects the bucket corner and side edge against wear while supporting effective penetration through soil and mixed material. The Fish Scale or Shark-style ribbed geometry provides additional wear material in the high-contact area of the bucket.

The side cutter is installed with mechanical fasteners rather than welding. Fastener arrangements vary between bucket versions; some use lower plow bolts only, while reinforced configurations may include an additional upper mounting bolt. Buyers should verify the existing part number, bucket-edge thickness, bolt spacing and complete hole pattern before ordering.

This product is the LHS component according to JCB’s designation. The matching opposite-side product is normally referenced as 333/D8457 or current 400/F0345.

This is an aftermarket replacement product. JCB and all related part numbers are used solely for identification and compatibility reference.
