Probably more than a new saw, sorry for my pessimism.

Sad but true.

The seals are £20 for the pair so just the labour. I would make a guess at 1.5 to 2 hours if they're any good at their job so about £140 all in? 

 

Then again I am pretty sure there is a tool for the seals so you can replace them in situe. Clutch off, pump off, flywheel off and then the tool pulls out the seal and you press a new one in meaning it should only be 30 minutes really. That could make it £50 odd quid

Any of you nice people can give me the sort of price this repair will cost at my Stihl dealer?

Thanks

If it is the seals ? But sorry i agree with others, just go and buy a new saw and you will have a few years use out of it then, replacing crank seals in a saw of that size n cost its not a done thing i would say and far better buying new saw,

Little Clamshell engine Paddy, its full strip to remove it out of the crankcase body. Be daft not to replace main bearings and re ring it if its coming that far in bits. Depending on condition of cylinder / piston / crank etc.

That's why I am wondering about the tool. It's 5910 890 4400 in the manuals. I've seen it a fair few times in manuals and thought "That would be handy as hell" especially if you clip a seal on assembly

The seals are clamped in between engine housing and sump pan if ya will, and sit behind a lip, they won’t pull out or press in, hence the full strip down and split apart, shall post a pic in a bit, got an old motor in a box lying around i think

Ahh that's really annoying! I've not looked at the 170 as I don't own one. If you have to strip it down fully then yea, just buy a new one.
