If it is like others I have seen you got to disassemble the crankshaft using a press. At least this one has a keyed position. But this TTI engine is not meant to be repairable as the bearing nor seals are available through Homelite or TTI. The bearing [or bearings] itself is a common one.

Unfortunately as AVB stated, the best way to remove the bearings is to throw the whole engine over the back fence. Need a 20 tonne shop press to get it out.

The motor is engineered to be cheap and nasty in every single way. I have several of them; they are powerful enough but I can't say they are a good motor. The quality going down hill doesn't help.

There are good half crank 2 strokes (eg Victa Powertorque, older homelites and Ryobi Ryan IDC engines) but this isn't one of them unfortunately

If you keep a look on the curbside collection, you will find 10 of them inside 20 minutes.

Or pop down to bunnings and buy a whole new unit (I am guessing its from a line trimmer) and keep the old bits for parts.

Sad, but its the way of the world now.


I would say your problem was that (like me) you let it idle and don't always use full throttle. These need full throttle to prevent the bearing failing. I don't use anything at full throttle unless required, so mine will go the same way.

The newer ones (2013 onwards) seem to like chopping out the bearings. You have to run them flat stick to prevent the bearing chopping out.
