Husqvarna 288XP Rebuilt question

[Tenmot]

Hi everybody!

I manage recently to get a Husqvarna 288 xp!

I started to dismantle and clean everything so I can make a spare parts needed list.

The original Mahle piston is a AB type (as I've heard 2/10 of mm wider than stock).

Most probably carbon from exhaust port fell in the cylinder and scored the piston.

I cleaned as much as I could and post some photos as I need some advise.


I got a Meteor type B new piston but it would be great if I could use the Mahle.

You think is usable?

The cylinder is original Mahle and in really good condition apart of the fact.

Any advise would be great!

Many thanks

usable

that look like a problem area to me ? I would pass and use the new replacement.
At worst the polished edge of the top and deep grooves will diminish compression ,at worst the piston will slightly rock leading to a shorter life for the saw.

I think the Meteor AB Piston and Caber ring they come with will serve you fine.

Hi all!

Thanks for the replies!
Unfortunately the Meteor is a B type.
I got some photos of the rings fitted.

From Mahle AB

I measure the gap looks like 60/100 of a mm in this case.

And from new Meteor B

 

[Gord404]

what is the gap on the meteor?.. I like around 10 or 11 to be safe and check your piston shirt gap.... If a gap is a little under I sometimes carefully take a couple of thou off the ring. - carefully with a very fine file I might be right or wrong but if they are too tight I don't like to risk it on a piston that size.

That looks a little gouged to me, if it was only scuffed I'd say run it.

Check ring end gap up above the exhaust port where the rings ride. .012” gap or so like mentioned

Hi all!

Thanks for the replies

I manage to get some photos of the rings fitted just above exhaust port.

This is the old original ring with clearance 65/100 of a mm.



And this is the new Caber ring that came with new Meteor B type.
Clearance 20/100 of a mm.
