Overview – Hydraulic Parts TANK;OIL 3099103 Series
Built to Cummins specifications, the TANK;OIL 3099103 serves Cummins engine lubrication as the oil reservoir tank; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
An engine oil tank that stores and supplies lubricating oil to the engine and its turbo and gear train. It holds the working volume, supports the breather and return path and keeps the oil settled, so a sound tank protects the bearings that the oil exists to protect.
Applicable Models & Applications
Fitted to Cummins engine oil layouts of this specification. Match the tank shape, port set and mounting against your engine or the parts book – oil tanks vary with the installation and the cooling arrangement.
Maintenance & Replacement
Inspect the tank and its seams for weeping and external corrosion at each oil service. A tank that loses level slowly is the most common cause of a low-oil alarm that comes and goes.
Service the breather and the level gauge together with the tank. A breather that clogs pulls a vacuum; a gauge that lies hides a real drop in level until the pressure light comes on.
Refit with clean seals and the correct torque. An oil tank sealed on a dirty face weeps under pressure and the engine bay ends up coated, which hides the next leak.
Keep common oil tanks for your engine on the shelf. They are cheap relative to the damage a starved engine does, and they are exactly the part missing when a reseal is needed today.
Price Reference (USD)
Budget roughly USD 120 to USD 380 for a TANK;OIL 3099103; volume orders and stock status can move this range either way.
