How to Service you Small Gasoline Generator

in Hive Motorslast year

You can't deny the fact that maintenance is the key to an engine long-lasting lifespan.


So today I'm gonna be showing you, how to service your small gasoline generator. It actually the same principle for all gasoline engine, the only difference are the build and maybe a few more technical stuffs.

Engine Servicing

Engine servicing is a series of maintainance procedures done from time to time, in order to keep your engine running in perfect condition, it also help to increase the lifespan of your engine

What does Servicing entail?

For this tutorial, I'm only gonna be showing you how and where to clean in the combustion chamber in a small generator, but servicing in bigger engines could demand that you change the oil in the engine or replacing piston and rings, e.t.c

But to make this less intimidating, I would divided the whole process into three sections:




So let dive right in:



This is the first step, and probably the most intimidating for most people, because of fear of not been able to assemble it back to it's original state, but not to worry, I suggest you take pictures of each part before you dismantle them.

On a generator like this, the first thing to loosen, are the nuts holding down the fuel tank



Removing the fuel hose, make sure the knob is in the off position, inorder to prevent fuel spillage (although at some points fuel still gat to spill).



This is called the engine block, this is where the fuel and air is ignited and compressed by the piston and the pressure produced by this combination drives the coil which is the electrical part of the generator (let's move on).

We also have to losen the nuts that holds them together.



Losen the nut holding the exhaust also


And pull the whole thing out,


it isn't necessary to remove the block completely but I find it more comfortable to clean the piston head without the block interfering.

At this point we've come to the end of the first section, which is dissembling


Have you ever had to clean up a little kid after they've eaten, that just exactly what we are gonna do, your generator has eaten quite a few fuel, so now it time to clean it up:



So we'll make use of our screw driver, to clear out all the carbon that has been stored up in the combustion chamber and on the piston:




After that, we take apart our exhaust system



remove the carbon stored up at the point where it was joined to the block


And that's all, we've successfully serviced our generator, as I mentioned earlier, maintenance may require doing more than just removing carbons, it might only require you changing your oil (most big gens I've worked on does not require loosing your engine block), so it all depends on the type, the size and manufacturer of your generator.


Let assemble our engine back

Note that if you removed the whole block, it requires a little trick to be able to insert it back

You see those two curved shiny things around the piston, those are the rings.


You'll also notice a tiny spaces on each ring, make sure those spaces are set around a little dot, you will find between those lines where the piston should sit, then apply pressure to both sides of the rings, insert the block while applying pressure on both sides of the rings


and push the block in, if you got it right, it should slid in easily.

Then the rest is just to fix and screw.
