Key features

• Caterpillar 536-3552 Triple Flange Idler Assembly The selection of Caterpillar undercarriage parts depends on your equipment’s specific series and the type of track in use: For most XHP Series and D3 Series models, if equipped with rubber tracks, the undercarriage requires a triple flange idler; This 536-3552 is the only compatible triple flange idler model for Caterpillar track loader series fitted with rubber tracks.
• Important Reminders: Some models may use a combination of "dual-flange front idlers + single-flange rear idlers" — be sure to check your undercarriage configuration before placing an order; If your model is in the compatible list but uses steel tracks, you will need a completely different single-flange idler to avoid incorrect purchase.

Installation & Maintenance Recommendations Official factory recommendation: When replacing the idler, simultaneously replace other vulnerable undercarriage parts and the rubber track — this ensures consistent wear levels across all components, maximizes the service life of the track and undercarriage parts, and avoids local excessive wear caused by mixing old and new parts. Reference for Dual-Flange Idlers If your model is originally equipped with a dual-flange idler (without the central guiding flange), you need to select the corresponding dual-flange model.
