If a track roller flange is touching shoe bolts and your first move is to swap the roller or retighten the bolts, you may be fixing the wrong thing. This is a reciprocal-contact problem. The marks on the flange and the marks on the bolt heads have to line up with each other, and with a track position where clearance disappears, before any single part can be blamed. The sources reviewed describe flange contact mainly with link pin bosses, rails and the track frame, not shoe bolts, so treat this as an unusual observation to verify.
Clearance near the flange can close for several reasons, each tied to a different part. A replacement roller with a different tread diameter, flange diameter or frame-to-tread dimension can change it. Worn tread raises the flange relative to the tread surface. Wrong-length bolts can prevent full thread engagement or cause interference. Alignment, side loading and turning habits are also commonly linked to directional flange contact, though that only justifies a check, not a conclusion.
Map both sides of the contact, from safe positions outside every pinch zone with the machine stopped and secured:
Flange side: polish, scoring, burrs or deformation, noted as inner face, outer face or tip, and where around the circumference.
Bolt side: bright faces, rounded or flattened heads, nicks, counted by shoe and bolt from a fixed reference.
Repetition: whether the same bolt position is marked on every shoe or only a few.
Spread: whether neighbouring rollers and the opposite track show similar marks.
Hardware state: missing, loose or odd-looking bolts, with movement marks or rust streaks.
Record that last group separately. Bright marks or rust streaks around a bolt head can indicate relative movement in the joint, so a marked head may mean a loose joint as well as contact.
Then collect each part's identity before assigning fault. You'll need the machine make, model and serial number, the roller's side and position, and its flange and tread dimensions. Add the shoe type, width, hole style and bolt spacing, and the bolt length, head style and markings. Also note the chain and pin boss condition, and which parts were changed recently and when. A mismatch in one identity can look like a fault in another, and the evidence alone can't separate them.
Hold the machine and ask qualified service to assess if both flange and bolt heads are marked, bolts are loose, missing or damaged, contact repeats on several rollers or shoes, or a recent replacement changed a part in the pair. Don't grind or file parts, remove hardware, swap shoes, adjust tension or retighten bolts. Retightening can mask a problem, and the torque specification belongs to the manufacturer.
