Options for a Stihl MS460

[Mag Craft]

I am working on a MS460 that is for me and not for flipping.
The piston and rings are toast from scoring but I believe the cylinder is salvageable.

So I have been looking on line and can see there is all kinds of ways to go on this thing.
I can get a meteor piston with caber rings and use the original cylinder.
I can get any combination of cylinder and piston and rings by names I am not familiar with.
I can also see that there is 54mm I believe cylinder and piston combo by names I am not familiar with.

So what have some of you guys used with success and had run good afterwards.

If I use the stock cylinder I will open the ports some and shape the upper transfers toward the intake.
I will also measure the squish and see where it is and see if I can lower it some.

Thanks for any advice guys.

I'd use a oem piston and use the oem cylinder for certain, what are you looking for from the saw?

Mine has a popup 064 piston and is a great runner. 100 115 78 200lbs of compression. Nothing fancy about it at all.

 

[Mag Craft]

Not looking for anything fancy. Just a woods port with some parts that are reliable is all.
The Meteor piston and cylinder do not look to bad and they seem to have a good reputation so far.
Not looking to do a pop up maybe just drop the cylinder by elimination the base gasket. I have not measured the squish yet so will wait and see on that.
I have done a lot of other saws just not a Stihl MS460 so just seeing what others have done. Why re-invent the wheel.

Oem cylinder will by far out perform any aftermarket one. I have a meteor 460 cylinder that runs ok but not like a oem one.

 

[Mag Craft]

Good that is what I want to know.

i have a 460 i built i bought a oem piston for it and it has 195 compression and its stock so i agree with jmssaws on oem

 

[Deets066]

Oem cylinder for sure, oem piston or meteor is fine. Caber rings are the way to go

I just built 2 460's and 1-046 and all the cylinders were good so i installed a meteor piston. So far so good on the 460. I had he 046 ported and have not ran it yet. I use meteor pistons on many of my builds and so far have had no complaints. Good stuff

 

[dall]

i was using meteor pistons for my builds also but the price of the oems pistons are pretty close to the same . but there is nothing wrong with meteor pistons they are my second choice

 

[mdavlee]

Oem piston for $55

 

[Mag Craft]

Yes Mike I have seen that price. That is not bad.

I was just being a little lazy and so I need to find my acid and clean up the cylinder. Sounds like oem is definitely the way to go.

 

[mdavlee]

Be careful with acid. I lost plating on 2 460 cylinders with it. I sanded the last few

 

[dall]

i sand and scotch brite my cylinders

 

[Mag Craft]

I have used acid in the past with some scotch brite and have not had any issues. Thanks for the warning though I do not want to be buying another OEM cylinder if I can help it. I usually dab the bad spots with a q-tip and then scotch brite it.

What grit paper do you guys use. Like 320 in that range.

Yea I have seen it thanks. Just call me old school. I have a ball hone also that I use for a final finish and please I know all about the pit falls of using a ball hone.
I have used them plenty of times on all kinds of cylinders and have never had a problem. You just have to take it slow and easy and not get aggressive.

 

[TJ the Chainsaw Mechanic]

OEM for sure.

 

[mdavlee]

Depending on how bad I've used 120 and then higher.

 

[MustangMike]

From everything I have heard, the OEM cylinder is the way to go, and either OEM or Meteor pistons. FYI, the Meteor piston has wider skirts than OEM if that makes a difference with your porting.

I have also seen that factory cylinder port timing on these saws varies quite a bit, so many of them benefit quite a bit from porting.

I have a 460 with an 046-D jug that Randy ported that will pull a 36" bar like nobody's business. I really like it!

 

[dall]

I wouldn't use a ball hone they are too rough and take the plating off
