The model name is the trap here. The older Cat 301.7D is a different machine on a completely different track — 230×96, with 33 or 36 links — so “a 301.7” isn’t enough information to buy on.
The same goes across the Next Gen minis: a 301.8 takes 66 links on a BFA serial and 70 on an H8X. Find the serial plate, note the prefix, then check the size moulded inside your current track before you order.
FAQs
What size rubber tracks fit a Cat 301.7 CR Next Gen?
230x48x70, from £189 + VAT, replacing Cat ref 535-9002.
Will these tracks fit a Cat 301.7D?
No. The 301.7D is an older, different machine on a 230×96 track with 33 or 36 links — nothing on this page fits it.
Why does my serial prefix matter?
Because Cat’s Next Gen minis split track sizes by serial. The 301.7 CR is JH7 on 230x48x70, while the related 301.8 runs 230x48x66 on a BFA serial and 230x48x70 on an H8X.
