Building a Stihl 024avs 026 hybrid.

[czar800]

I've had this toasted 024s for a little while and decided it's time to get her running.

It's a 024avs which makes it a perfect candidate for 026 top end!

Thanks to @dall for really helping me out with a crank, jug, coil, oil pump and a few other parts!

( That's the wrong top cover in the picture)

lol how come this isnt done yet

Stock 024 jug is on the right and the 026 on the left.



First step was to clean everything up.

 

[czar800]

I used a blow gun and what ever else I could find with very hot water.

The degree wheel is pulling double duty..... you see what I did there.

Once I got the cases split I found out just how bad the bearings were.

True!

I ended up having to weld a few beads on the bearing to get it out.

Yeah it's a ugly weld I was completely out of gas.

Subbed.

The cases are both good.

Subbed.

So it's an 026/24S crank and an 24S case?

Remember you gotta cut off the two rear top fins on the 26 jug if you wanna fit it under the 24 cover.

An 026 flywheel won't hurt it either. Moves a lot more air.

It's getting a 026 crank and jug. The rod bearing was bad on the 024s crank.


I'll be trimming & porting on the jug very soon.

I'll be looking around for a 026 flywheel for right now it's got the 024s.

To clean up the jug I used the @Mastermind method.

That's just a piece of brake line with a slot cut in it.
