Is there a difference between the steering clutches and Brake bands on D21A-5 and D21A- 6 I have a D21A-5 and I found lots of brake bands and clutches for D21A-6 I didn't know if there's a difference between them
Small visual differences that may not matter , fiber segment have different rivet patterns . Weight is listed different , I doubt there is the 4kg difference . Part numbers are listed as different . BRAKE BAND D21A-5 S/N 45001-UP Komatsu Part catalog k-part.777parts.org
Before I pulled the trigger on the part that didn't list as fitting my machine I would call a Komatsu dealer and verify fitment....sometimes parts are non returnable/non refundable. jmho
