GX340. How do I remove pump from engine? - Honda Garden

the chart shows figures of 10.7 hp-8.0kw with a torque of 19.5 ft/lbs- 26.4nm at 2500rpms ( max net torque)
the chart shows gx390 is 11.7hp (8.7kw) but the torque is the same as the gx340
you can get these figures from world. honda com or by going google and typing in--torque range of honda gx 340 motor at max rpms
10 hp engines running at 2500 rpms will be good for gensets of 5kw continuous out put as most makes run that size engine

Excessive fuel entering the inlet manifold, carby needle and seat not shutting of fuel flow , remove and clean fit new gaskets and needle and seat if worn.

I'm sorry if I'm not quite understanding the question.

Are you saying the rope MAY be too short and so the amount of pull available is also shortened?

Hi,the quick,but not final fix for this issue is to use a oil additive similar the one-s from the cars,but make sure you are using the one required by the fuel type.The engine is worn out,needs overhaul,soon or later.Good luck,regards

Align crankshaft and balancer gear first. Rotate crankshaft and align timing gear. Alignment mark may be hard to see on crankshaft for timinig gear.

The Honda engine will use standard 30W. the pump will use 30W non-detergent.

You have a nice setup, lots of power. The honda gx340 has a compression release built into the engine so it should be relatively easy to start. With the pressure pump under load however, it will be very hard to pull the rope. With water connected hold spray gun open so water is running out tip and pull rope to start (for easy start, remove tip from gun) . If it still feels very hard to pull rope while holding gun open, most likely problem with lubrication in pump or engine valves are not adjusted correctly preventing compression release. If you suspect problem, go to store where you purchased the unit or any store that sells gx340 and pull the rope to get a feel of what force is required to start engine and compare to yours. Good luck.

I have not worked on Dunlite generators, however have worked on many different brands using the GX340. When removing generator parts, one must keep in mind the brushes contacting the armature. Remove brush pack if any and set to side. Next unplug stator wiring making sure to draw diagram of connections. Remove bolts mounting generator/stator housing to frame and carefuflly pull off leaving only armature /rotor on the crank of the engine. Remove the long bolt thru rotor into crank. Now you will need to apply penetrating oil to the shaft of the engine to loosen the rust on the taper. It may take several applications. Place a piece of hardwood against
metal to protect the rotor and firmly rap with hammer on
both sides. You may need to use pry bar against engine
and rotor as you hammer hardwood. Repeat as necessary,
some rotors will be very stuck due to rust. Be very
carefull with hammer and or prybars not to damage
windings. Have patience and let oil work. Good luck.

HI, It sounds like it is just stuck on the keyway as these can be very tight. You need to force the pump of evenly on either side and should come of if patient.

it mus be over heated.
