Overview
An owner walking through his own 100-hour service on a 2025 Mahindra 1635 HST cab model after completing it. Covers which bolts to loosen and their sizes (19mm, 14mm, 3/4-inch), two hydraulic/transmission filters with part numbers, fluid choices (Mahindra Universal 3 synthetic, Shell Rotella 15W40), and the roughly 9-gallon capacity. A practical quick-reference for 1635 HST owners facing their first fluid service.
An owner-operator sharing post-job impressions from his own property, with follow-up videos on fuel filters and front axle fluid planned.
