STIHL The Official Stihl Chainsaws Thread

[FergusonTO35]

I'm the type who drills ball joints and tie rod ends to screw in grease fittings. Trying to resist the urge to drill grease holes in my Stihl bar tips.

Same here. Other day I pulled the axle from the wheel hub on our 4x4 to get a zerk in the new lower ball joint.

Greased bar tips collect crud.

In my experience.

I agree, WD-40 to help loosen up the gear if needed, but other than that let the bar and chain oil do its work.

Wouldn’t help anyway, I’ve seen so many Stihl bar rails wear out before the tips ever quit under normal conditions. I’ve changed a few out on pro bars that guys bore cut with a lot but most regular cutting wears the rails out first.

Fellow brought in a really whupped MS170, basically no compression. He really wants it going again (sentimental reasons...) and I'm leaning towards a China short block. I see them anywhere from around $25 to $130 (LRB). I'm not expecting a high quality unit for replacement but is there really any reason to spend an extra $100? Does anyone have experience with any of the bargain basement short blocks?

Thanks,

Mark

I went ahead and tore the 170 apart, piston and cylinder look fine but compression is only 105 PSI.

Sounds like new rings bearings and seals will do it maybe a piston

Chris - do you know what the cylinder and piston measurements should be? I don't mind putting a piston in it, but I'd like to know the cylinder is still within specs.

I don’t know for sure if my 170-180 repair manuals say but I will look this afternoon and let you know if it says.

I don't think there will be anything more than the standard cylinder/piston diameter of 37 mm and ring thickness of 1.2 mm.

If the chrome plating is still in good condition and you can't see the dull aluminum underneath, I wouldn't worry about the cylinder.
