Complete engine block GY6 139QMB 12" (short axle) China scooters/Agility 12"/ Like/Kisbee/Django/Fiddle <2009/Orbit <2009

In the event of a faulty engine, it is often not unwise to completely replace the engine instead of overhauling it.

When do you replace the GY6 139QMB short axle 12" engine block?

If something crashes in your engine block (at higher revs, for example), a lot of things can go wrong.
● Gears crash or break
● Certain parts no longer receive an oil supply, run dry and break
● Bearings break or become trapped
● The above also applies to seals
● Your crankshaft bearings, or one of them, breaks

And so on... What goes wrong at such a bad moment is too much to mention. It often comes down to a huge bill with your mechanic. But what you could also do once you add up all the costs might be to buy a completely new engine block! It happens that this is cheaper than replacing everything separately.

Assembly: GY6 139QMB 12 inch short axle engine

Now you would think that this is an impossible job to do yourself, but that is not so bad. In terms of special tools, you only need a lock key and flywheel puller when (if necessary) the ignition has to be transferred. This is because the GY6 138QMB motors have 2 types of ignition. To provide a clear picture, we made an assembly video. The engine block has already been filled with oil, just arrows before use. The advice is to change the oil after 500 km to increase the life of the engine. You can then have the standard maintenance carried out in accordance with the workshop manual for your type of scooter.
