The Honda GCV530 is a small (530 cc, 32.3 cu-in) 90° V-twin air-cooled 4-stroke internal combustion gasoline engine with vertical shaft, manufactured by Honda Motor Company for general-purpose applications, such as: commercial lawn and garden equipment, tractors, construction and industrial equipment, agricultural equipment, small vehicles.
This engine has two cylinders, integrated cylinder, and head, overhead camshaft, two-barrel carburetor. The Honda GCV530 engine has transistorized magneto ignition, recoil or electric starter. This is the same engine as the Honda GCV520, but it has a different carburetor and as a consequence a higher power and torque.
Cylinder bore and piston stroke are 77.0 mm (3.0 in) and 57.0 mm (2.2 in), respectively. Compression ratio rating is 8.0:1. The GCV530 produces 11.9 kW (16 HP) at 3,600 rpm and 36.5 N·m (3.72 kg·m, 26.9 ft·lb) of torque at 2,500 rpm.

Hello, we are not a supplier of engines or spare parts, we are only an information portal with technical specifications.
Whats the model number of the mower. Need to find me one since I have 3 new Honda mowers. Wrisnear@gmail.com
How do you time the cam shafts please
Hallo,
für ersatzteile dürft ihr euch gerne bei mit melden !
Gruß Marcel
I have a 2018 model Honda 2417 with a GCV530 engine
I have noticed that there isn’t an oil filter, is this correct?
I have a Stihl mower with a GCV530 Honda engine without an oil filter. There are several versions of the engine and not all have an oil filter.
I am interested on a gcv engine over 6,5hp that my other engine is! Which models are the next ones and how many hp and cc are they! Do you ship the engines to Greece ?
what type of oil should I use for the rear differential ?
