Suzuki engine removal tool
 

Hi does anyone know how to remove the special nuts that fix the engine in?

How much is the proper tool or does anyone have a tool that does the job that I could rent, I will of course leave a full deposit if it is expensive?

Are there any other special tool that needed to take the engine to bits?

Many thanks in advance

I removed an engine with just a normal socket set, didn't need any special tools. That was on a curvey

The pointy has these speical nuts that have funny ends on them there dont seem to be any sides just a "castle" top with ridges.

Those aren't the engine bolts, the bolts hold the engine the 'castle' parts are adjusters so the engine will be held correctly in the frame. You often won't need to move them to remove/replace the engine.

If you do find you need a castle nut adjuster several people have made one by taking a dremmel/hacksaw to a socket of around the correct size. For my tool kit for instance there's a ton of imperial sockets I've never used so sacrificing one wouldn't be a big deal.
