Sleeve removal problem

[Lalojamesliz]

When I removed the sleeve from my os .18tz it was hard to remove it. I used a zip tie's head to push the sleeve buti had a really hard time. Why??? I just took out the sleeve from my brothers old traxxas pro.15 and it slid right out with using a zip tie.

Differences in machining tolerances. The tighter fit will in general offer better engine life.

Your talking about the block and sleeve tightness and not the piston and sleeve right?

Yes :yes:

Yeah I have seen the same thing with blocks that you can pull them out by hand. I had one I had to bake and use the zip tie method. As Racer pointed out your better quality engines will be build with a lot tighter tolerances.
