Confirm the J550 adapter size
Use the full tooth and adapter markings to confirm J550. Check the rear pocket and horizontal side-pin arrangement against the existing assembly. Do not identify J550 solely from overall worn-tooth length or the machine model. Other J-Series sizes, Cat K-Series and Komatsu KMAX use different fitment requirements.
Looking for another size? Return to the J-Series system guide before choosing a different adapter size.
Choose the tooth profile after confirming fit
Choose a profile for the material after confirming fit. General-purpose or long points suit many everyday digging jobs; penetration profiles concentrate force, while heavier abrasion profiles provide more wear material. Availability depends on the confirmed size and system. A wider or sharper tip does not change the adapter interface.
