Gin Posted April 20, 2016 Share Posted April 20, 2016 You need to apply sudden, concussive force repeatedly to the outer walls of the casings to ease the bonded faces.Hurl it against your garage wall a few times and it should give I am totally joking Classic.. Take it to a garage who already have the tools. Quote Link to comment Share on other sites More sharing options...

Joeman Posted April 20, 2016 Share Posted April 20, 2016 Many years ago as a 16year old lad, I regularly split two stroke engine cases apart. I don't remember using any specific tools.Tapping the end of the crank and gently prising with a kitchen knife used to do it! Quote Link to comment Share on other sites More sharing options...
Fozzie Posted April 20, 2016 Share Posted April 20, 2016 You do run a risk with damaging it that way but it rarely happens. It's more likely if you're more abusive with the old rubber mallet though I got a generic set of pullers from ebay. Just remove all that you can before you split the cases in case bits go flying. You will need a threaded puller for certain things though like the timing rotor. Best to tear the engine down and if anything looks like it needs special tools, then get them. I split the cases on Moo's CBF to have a look at the gearbox and did it with no great difficulty. The most tedious part was scraping all the case glue off and reapplying it afterwards.

eastanglianbiker Posted April 20, 2016 Share Posted April 20, 2016 many times i have used block of wood and a soft mallet to work the casings open and if you look around them on some of the older 2 strokes they actually had indents in the crankcases which were pry points Quote Link to comment Share on other sites More sharing options...

aleyj Posted April 27, 2016 Share Posted April 27, 2016 Go to top of a multi story and drop it, I know it's similar to gin's suggestion, but it's easier to drop than throw it! Can't guarantee that you'll be able to put it back together after, but it'll certainly split the cases, probably won't need to undo any bolts either.
