impact wrench... nuff said

 

[r_chez_08]

is there a way without an impact wrench, as i dont have one.

 

[lemegacool]

i see two possible ways...

stuff the cylinder with rope so the piston stops and allow you to remove said bolt

or (what id do) jam something in the flywheel or cooling fins to tock the shaft

Or.. you can get a cheep impact gun and then u will use it for a lot of stuff!

just use a ratchet and go very fast on the first push

yOu can also do like me and modifiate a ratchet extender with a grinder to fit it in your drill. If you have a good drill you will be ok to torque it.

ok, i will try some of these tequniques thanks.

DO NOT put anything in the flywheel cooling fins to stop the shaft from spinning. It will just crack the fins, trust me, i speak from experience. Put COTTON rope down the spark plug hole. Make sure the rope is clean of any sand or dirt as u dont want bits of sand in ur cylinder. U probably need about a metre of rope (3ft ruffly in american terms) to stop it from turning over.

That should work well. Thats all i do to lock it.

I have never broken a cooling fin, the trick is to get something that will go all the way across the flywheel and get two fins at once.

i know what i will do, i will jam something in the recoil dog.
thanks for the help! i will go try that now.

yea but its not a good thing to tell someone trying it for the first time, i broke one in my time and only one but if i didnt know i would have cleaned the FW off

 

[r_chez_08]

i found out that the bolt was hand tight, but every other time it was tight.
but i got it off, and i inproved it slightly by turning my stick welder down to 30 amps, and welded/ made splattery stuff over the inside of the drum and shoes.
