61021527 Cap, Oil Filler – Precision Sealing for SANY Diesel Engines
The oil filler cap with OEM number 61021527 is a standalone component that also forms part of the larger cover assembly (61001601) on SANY engines. This cap is designed to be a direct, secure fit onto the oil filler neck, providing a reliable seal that prevents oil splashes and maintains crankcase pressure. The cap is manufactured from high-strength, glass‑reinforced polymer that resists warping and cracking under continuous exposure to engine heat (up to 120°C) and chemical attack from engine oil, diesel fuel, and coolant.
Every genuine 61021527 cap features a molded-in sealing ring groove that holds a premium nitrile rubber (NBR) o‑ring. This o‑ring maintains its elasticity and sealing force for thousands of opening and closing cycles, preventing hardened, cracked seals that are common on aftermarket caps. The quarter‑turn locking mechanism provides a positive stop with an audible click, confirming that the cap is fully closed.
Using the authentic 61021527 cap eliminates the risk of a loose or missing cap, which can cause oil mist to escape, leading to engine bay contamination, belt slippage, and even engine fires. The cap also prevents dust, sand, and moisture from entering the lubrication system – a critical requirement for equipment operating in mining, construction, and agricultural environments.
Leak‑Free Seal
Precision‑molded NBR o‑ring provides positive seal against oil splash and crankcase pressure.
Heat Resistant
Cap body withstands continuous under‑hood temperatures up to 120°C without deformation.
Ergonomic Grip
Ribbed outer surface allows easy removal and installation even with greasy or gloved hands.
Contaminant Barrier
Seals out dirt, dust, and moisture – essential for engine longevity in harsh environments.

Why the Genuine 61021527 Oil Filler Cap Is Superior to Aftermarket Alternatives
Aftermarket oil filler caps are frequently made from low‑grade plastics that become brittle and crack after a few months of heat exposure. A cracked cap allows oil mist to escape, coating the engine with a film of oil that attracts dust and creates a fire hazard. Worse, a missing or loose cap – common with poorly fitting aftermarket designs – can allow large amounts of oil to splash out, leading to low oil level and eventual engine seizure.
The genuine 61021527 cap is manufactured from glass‑reinforced polyamide that maintains its mechanical properties at up to 120°C. The NBR sealing ring is formulated specifically for continuous contact with hot engine oil and diesel vapors, maintaining its elasticity for over 5,000 operating hours. In contrast, aftermarket caps often use cheap silicone or plain rubber that hardens within 1,000 hours, leading to oil seepage that may go unnoticed until a major oil loss occurs.
The quarter‑turn locking mechanism on genuine 61021527 caps has been tested for 10,000+ cycles without failure. The positive stop and audible click give service technicians confidence that the cap is fully closed. Aftermarket caps often rely on friction alone, which can vibrate loose over time. For fleets operating in high‑vibration environments (mining, quarrying, heavy haulage), the genuine cap eliminates a common source of preventable engine damage.

Installation & Maintenance of Cap, Oil Filler 61021527
Replacing the oil filler cap is a simple but critical maintenance task. First, ensure the engine is cool to avoid burns. Turn the existing cap counter‑clockwise to remove it from the filler neck. Inspect the filler neck sealing surface for any damage or debris; clean with a lint‑free cloth if necessary. Remove the old sealing ring from the cap groove (if present) and discard it. Install a new genuine 61021527 cap – it comes complete with a factory‑installed NBR o‑ring.
Place the cap onto the filler neck and turn it clockwise until you feel a distinct stop and hear an audible click. Do not over‑tighten or use tools – hand-tight plus a quarter‑turn is sufficient. After installation, run the engine and inspect for any oil mist around the cap. If oil seepage is observed, confirm that the cap is fully seated and that the filler neck is not damaged. For preventive maintenance, SANY recommends inspecting the cap seal every 2,000 operating hours or 12 months, and replacing the entire cap every 5,000 hours. A worn seal will show cracking, hardening, or flattening; any of these signs warrant immediate replacement of the 61021527 cap.
Never reuse an old cap after engine overhaul – the o‑ring takes a compression set and will not seal properly. Also, never drive a vehicle with a missing or damaged oil filler cap; doing so can lead to oil starvation, engine damage, and fire risk. Keep a spare genuine 61021527 cap in your service truck for emergency replacements.
