FAQ

What is 504315785?

A CNH engine accessory belt tensioner. Case / New Holland parts systems and Google both index this number. This page is the photographed assembly, not a CAT excavator shopping title.

Is 2856173 the same part?

New Holland dealer pages list 2856173 as replaced by 504315785. Still confirm on your serial before ordering.

Will it fit a CAT E110B?

Do not assume yes. Those Google/Amazon titles are mixed. Match the number on your old tensioner or the CNH/FPT catalogue row.

Are you a CNH genuine dealer?

No. Independent exporter. The carton in the photo is for identification. Quotation states source.

How do I get a price?

Form or WhatsApp +91 96720 55759 with qty, country and https://www.pioneermitra.com/products/cnh-504315785-belt-tensioner/

Case, New Holland, CNH, IVECO, FPT and Caterpillar names and part numbers are used only to identify the photographed belt tensioner and to warn against mixed Google shopping titles. Pioneer Mitra Engineering Company (IEC BJDPB6241D) is an independent exporter — not affiliated with, endorsed by or authorised by CNH Industrial or those OEMs. “Genuine” on a carton is not a Pioneer Mitra dealer claim.
