Yanmar B27-2 Parts Catalog

A starved intake on an older three-cylinder diesel shows up as smoke and weak digging. The Air Cleaner section breaks the intake assembly into its individual pieces so you can order the correct element and hardware for this serial range instead of guessing from a generic listing.

Decades-old radiators clog, weep at the seams, and crack their mounting brackets from vibration. The Radiator & Mount section shows every part of the cooling package as an exploded figure with Yanmar part numbers, so a leaking core or broken mount becomes an order, not a fabrication job.

Rust and sediment in an aging fuel tank work their way toward the injection system and cause hard starts and power loss. The Fuel Tank section identifies the tank, cap, and associated fittings so you can replace contaminated or corroded components with the right parts.

Exhaust systems on machines of this era rot from the inside, and a mismatched aftermarket silencer rarely fits the original routing. The Muffler section gives the factory part breakdown so the replacement bolts up the way the original did.

Perished rubber engine mounts let the diesel shake the whole frame and hammer other components loose. The Engine Mount section shows the mounts and their fasteners as separate numbered parts, which matters when a corroded bolt has to be replaced along with the rubber.

Worn linkages and stretched cables make engine speed hang or hunt. The Accelerator section lays out the throttle components piece by piece so you can spot which link, spring, or cable in the chain has failed and order exactly that part.

Repainting a faded B27-2 without the factory scheme means guessing at colors. The Painted Color List identifies the original finish for the work equipment, bonnet, fuel tank, hydraulic oil tank, and boom and blade cylinders.
