80 vs 84 — don’t get caught out
The single most common mistake at this size is ordering an 80-link track for an 84-link machine (or vice-versa). Width and pitch look identical. Count the links the whole way round. 84 links = this page; 80 links = our 300×52.5×80 page.
FAQ
Will an 84-link track fit an 80-link machine?
No. The link count must match exactly or the track won’t seat on the sprocket correctly.
Which CAT 303.5 generation uses 300×52.5×84?
The 303.5 / 303.5C CR / 303.5D CR. The newer 303.5E CR and 303.5E2 CR use a 90-link track (300×52.5×90).
