Brakes and transmission, lighting, steering and front axle: these are some of the groups among more than 90 parts for the Landini 8550 from the 50 series.
The Landini 8550 has more than 90 replacement parts on this page, from GRANIT and from makers such as GRAMMER, Cobo, KS and Perkins. They cover the jobs that come up on an older tractor of this type: an engine that burns oil, a lift that drops, a brake that feels soft or a seat that has seen too many seasons.
Piston ring sets and complete pistons are here for anyone opening up the block, together with sealing rings, gaskets and seals. On the fuel side you will find feed pumps and regulator springs, and the cooling system is covered with radiators. Silencers complete the exhaust.
A tip before fitting new rings: measure the cylinder bore first. If there is a clear ridge worn at the top of the bore, fresh rings will not seal well against it, and a complete piston set is the better repair. Check each ring gap in the bore before fitting, and stagger the gaps around the piston so they do not line up.
After rebuilding a brake cylinder, flush the whole system with fresh brake fluid. Old fluid absorbs moisture and attacks new rubber cups far sooner than you would expect.
Regulator springs are small parts that are easy to overlook. A tired spring lets the engine speed hunt under load and leaves the idle unsettled, so it makes sense to replace it while the fuel side is being worked on anyway. Silencers are best fitted with fresh clamps and brackets, since a loose box soon cracks at the pipe from vibration.
The type plate tells you that the machine is an 8550. Beyond that, the old part is your best guide. Pumps, radiators and cylinders usually carry a reference number cast or stamped into the housing, and comparing that number with the details on this page avoids ordering the wrong thing. With a hydraulic pump, also compare the direction of rotation and the shaft connection.
The 8550 belongs to the Landini 50 series, and two related models have their own page. The Landini 6550 and the Landini 7550 each list the parts that fit that specific model, so order for the type on your plate. Tractors from the rest of the Landini line up are grouped under Landini parts.
