This is not true unless you take it to a butcher shop. Yes they remove the sleeve, by heating up the jug in an oven and pressing it out and pressing the new sleeve back in. I still have my stock jug and piston, in perfect condition. That is how mine was done.


let me ask you this why put in a sleeve if its the same size? the 440 sleeve is bigger therefore the cyclinder has to be machined cut how ever you want to say it.....am i the only one that thinks this....can we get some opionions here or am i just wrong...oynot400 who ever did you work had to cut some of the cyclinder wall to fit a 440 sleeve in there.. ask them......416 is 80 over ......this is what i thought and if i am wrong i want to know for future reasons?????

KAT YOU HIT THE NAIL ON THE HEAD. SLEEVE HAS TO REMOVED FROM JUG THEN JUG HAS TO BE BORED TO ACCEPT A BIGGER SLEEVE AND THEN BIGGER SLEEVE IS INSTALLED INTO BORED JUG. 406,416,426 CAN USE STOCK SLEEVE JUST BORED OUT TO SPECS.:square

My bad, I typed too quickly without reading the post to close. Yes you have to bore out the jug to fit the larger sleeve. I was thinking that kat400ex was cutting the sleeve out of the jug.
Sorry about the mix up. :)
