Title: STIHL 024 HELP PLEASE.........AV, WOODBOSS AVS, OR SUPER?????
Post by: CATDIESEL on March 05, 2013, 08:19:08 pm
i bought a real nice 024 woodboss avs that had been setting for a while. i know the "supers" are supposed to have a longer stroke? does AVS mean it is a super? i need the jug off of it, so i measured it against a standard jug. one is stihl, one is mahle. they both measure the same from the squish band to the base,  same stroke. both pistons are the same height exactly. so what gives, i want to put this top-end on a non-super saw. i just do not want to destroy anything. are the differences in the crank?  or could it just be my saw has the "super" covers on it? please give me some insight here guys,  thank you

So just, put the phone down with my friend, the woodboss avs has the 026 house and krank but cilinder and piston are the same  AV and woodboss AVS( note: it could be that the topcover might not fit after the swap and PUT THE PISTON AND CYLINDER WITHOUT THE RINGS LOSE TOGETHER AND SEE IF IT TURNS ALL THE WAY  )


The 026 has the 2 mm longer krankshaft ;)

Cheers ,
Saul

Well you can do what you want .I had the bright idea of changing the cylinder on mine to an 026 but after I gutted the muffler it pepped it up enough I'm not going to do any more to it .

Now these little things never will be an oak slayer but if you can get them to breathe right they are a pretty neat little light weight .The things are light as a feather ,a tank of gas lasts forever .Up to maybe 12 inch stuff they get er done pretty good .

I don't think they would be a good cantidate for a 3 cube cookie cutter because it lacks a full 1/2 cubic inch .That's a bunch when you are only dealing with 3 cube to begin with .

i checked, and rechecked all of the specs today. one jug is a stihl, and one is a mahle, one has open,and one has closed transfers. but the bore depth/stroke inside the jugs are within .010 of each other. is it at all possible the extra displacement comes from the crank? the crankshafts in each of the cases are definately different.

I don't know what was said earlier but a 024 has a 30mm stroke. the 024 Super and 026 have a 32mm stroke.

EDIT: I see someone has already said that.

THAT IS THE CASE INDEED ;D

Yah , then you need the 026 crank indeed

 But still ( PUT THE PISTON AND CYLINDER WITHOUT THE RINGS LOSE TOGETHER AND SEE IF IT TURNS ALL THE WAY  )

and if it turns all the way, then put two bolts to hold it in place and put a piece of solder rod in the spark-plug hole,

turn the engine (with the hand or tool)  through the compression and measure it, then you now what feet-gasket you need

It all sounds good providing you have about a pick up truck full of parts to tinker with .If not you'll have 3 times the amount of money in rounding up the parts than you could have  landed an 026 for  .

Kind of like a few who have grafted an 038 mag cylinder to an 038 av .It works but with the amount of work in redrilling the cylinder to fit the crankcase etc it might have been a better choice just to find a mag to begin with .Quit frankly truth be known they probabley made more mags than they did av's so they aren't that hard to find .Might also be true concerning the 024 and 026 because you see more of the later than the former .
