Stihl 045-056 measurement.

[Red97]

If anyone has one tore down, or just a crank. I would like the small/piston end connecting rod dimensions. Bore diameter and rod width.

Oh and if anyone has a 56mm oe piston they want to get rid of let me know

Thank you.

You can track that down through the ipl specs. Look at the wrist pin bearing OD and length.
17mm ID x 14.5mm wide.

Thank you, didn't know the ipl broke it down that far.

Exactly what I was hoping for.

I just got a box full of parts and if I'm not mistaken there's a 056 cyl and piston in there not sure of the conditions.

 

[Milkman31]

I hope this may help in some way.

I hate to say it but it's junk. The ring pin came loose.

Darn. I have one of the am 56mm piston's. Looks useable, but would rather find an oem.

One of those red barn pistons?

red barn is not quality.

Yes, other than inside the pin boss. The piston looks fine, just the normal casting flash.

Lrb piston is better than no piston imo...

What is the difference on the installed height of the 660 BB piston vs these old 56mm OE slugs for 045&056 mag saws? Anyone know
