Pan Car O-ring Replacement Pack 4.5X1 (10) - Arrowmax AM-931013  [AM-931013]

Replacement O-rings for pan car differentials

This Arrowmax AM-931013 Oring 4.5X1 (10) contains ten replacement 4.5X1 O-rings intended for use in RC pan car gear differential units. The set is suited to routine maintenance, topping up seals, and fine-tuning spacing where reliable sealing is required.

Compatibility covers pan car gear diffs in both 1/12 and 1/10 scales, particularly in compact or low-profile diff assemblies. The rings act as seals or slim spacers to retain diff fluid and stabilise mesh under dynamic loads.

Fitting instructions: inspect gear faces and shafts for damage before fitting, avoid stretching the O-ring excessively when installing, and ensure the ring sits evenly in its groove. Replace rings in matched groups to keep sealing and behaviour consistent across the diff.

Setup advice: renewing worn O-rings can eliminate small leaks and help preserve fluid distribution under cornering, subtly affecting traction and consistency on pan car chassis.
