Mastermind Meets The Stihl MS440/460 Hybrid

[Mastermind]

This saw has been around the world, and is not done traveling yet. It came here from New York, and will be leaving here for Washington State. When it got here it was a new unfueled saw with the Gilardoni cylinder. I replaced that with a very nice Mahle 046 D-shaped cylinder and a new Meteor piston kit.

Here's some pics.....

The Gilardoni cylinder.....

Thanks for hooking us up with the 046 cylinder for this build J.

'twas muh last one.

Ah well, there's more out there....somewhere. :dunno:

 

[Mastermind]

The Mahle 046 cylinder.

In pretty good shape for a jug that's over twenty years old ain't it?

A little rough there.......we'll straighten that out.

This should give you an idea how much the bolt holes need elongated.

Boy these Meteor piston are purty.

These next two pics show the rough in process of the exhaust port.

Notice the card stock? I use it to gauge my height. The pencil line is for width.

Rough in on the transfers. Notice the cut squish band?

Gilardoni cylinder

Are those Gilardoni cylinder and pistons not very well built ?

Ha there Randy
Can you please explain the advantages of going hybrid ?.

Thanks

 

[Mastermind]

Roughing in the intake.

It's not hard to cut through on the 046/460 because of the offset of the port.

That's plenty big enough to get the fuel in.

All done, cleaned up and ready to go back together.

I really like this sealant. It's Loctite 515, it doesn't harden unless it's in an area that's less than .030. That way whatever squeezes inside the engine washes out. It's also easy to clean up on the exterior.

Have to do a bit of clearance work.....especially if you drop the jug.

Oh no I'm not implying that the Gilardoni cylinders aren't high quality. They are among the best I'm seen.

Welp.......there ain't no replacement for displacement.

The 440 is a lighter, nimbler saw than the 460........it's nice to have the added power in the smaller package.

 

[Mastermind]

I pulled the flywheel and trimed a bit from the key to advance the ignition timing a bit. It wakes these puppies up nicely.

Spacers have to be placed here when the 460 top end is installed.

 

[Officer's Match]

I bet you could pay for that whole saw with test flights.

 

[Mastermind]

Tuned to 14,400 in hard ass white oak. Biggest wood on the place right now.

Thanks Randy
Sounds good to me.:msp_biggrin:

 

[Officer's Match]

Sounds nasty, and still fresh to boot. Dang I'd love to run that in 10 tanks or so.

 

[Tzed250]

Nice work!!

I can hook up that 460 in your sig. The 1128 series is one of my favorite saws to build. :msp_sneaky:

I just looked in my Stihl catalog and it lists a 12 oz weight difference between the saws. Is the weight savings the only reason to go this route over a 460?

Either way, cool thread and pictures
