OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines removing the blade plate

I was wondering is there any easy ways to remove the blade plate without the engine turning over. I have one on a vc160 that just wont budge

on a 2t victa I generally feed a meter or so of fairly thick cotton rope into the cylinder and lock the engine, and hang on a breaker bar, sometimes they are just too rusty, and have to be cut.

If you have a (good) rattle gun its quite easy.


I havent had a 4 stroke give me major grief yet, a foot on the blade disc, and smack the L bar with a rubber mallet a good few times usually cracks them. (lets face it if a 4 stroke has been neglected to the point of the blade bolt being stuck in there solid, the engine itself is likely to be bad anyway.) a rattle gun is my recent weapon of choice for the main center bolt anyway, I have one on hand and they are just easier.

Yea this one is pretty rusty ill try the rope but say if its gotta be cut would.i use a thin cutting disc an cut just before the thread?

Hi Nathan,

If you're doing a bit of work like this it really is worth getting a rattle gun, it makes the job so much easier. My weapon of choice for careful cutting is a 50 x 1mm cut off disc on a die grinder.

You can also get those skinny cut off wheels for a normal grinder, they are brilliant, just cut close to the crank, dont actually cut the thread, do it on both sides and a good wack with a cold chisel will break the nut in half. The nuts are cheap, just clean up the crank thread really good and tou will be good to go.

Really tight Victa 2-stroke crankshaft nuts do need impact to break them loose.
In the absence of a rattle gun, another way that nearly always works, is to use a long 1" AF ring spanner. 'Angled' type is better than 'cranked', but both will work.

With the mower turned on its side, use the toe of your boot to hold the spanner on the nut. Hold the blade disc edge tightly with one hand [gloves help], and hit the spanner hard with a steel hammer. About a 32oz ball peen hammer usually works best.

Failing that, as Joe says, those 1mm cutoff discs are brilliant, used carefully.
