dolmar 5105 piston....solid or windows?
« on: January 21, 2014, 04:12:29 am »
I recently purchased a dolmar 5105 knowing that it had problems.  Well the cylinder cleaned up beautifully but the piston was to far gone. I have found 2 different pistons for this saw windowed (63) & solid (62) so which one? The saw came with a windowed piston & I am 99% sure it was never messed with so go back with that?

Ok,that definetly shows the windowed piston so that is what I will order. I had not seen that yet. Thanks 660magnum. I believe you have stated in another thread that you have a 5105....Do you like it? I am very excited to get this back together and run it as the weight is great and if it is as powerful as i have heard and the #'s say it will become the quick go to saw in my Dolmar collection.

My 5105 is a very powerful chainsaw for 50cc. I like it very well.

Windowed piston is NLA unless a dealer happens to have one.  The pic in the listing hasn't been changed.  You will get a slab piston.  I know that for a fact.  I have 2 63 slab pistons in stock.  I wouldn't worry too much about it the slab piston works real well.  The 7900 was changed from windows to slab piston too.  The slab pistons on both 5105 and 7900 are lighter than windowed and a tad wider skirt.

Update.....ok I tried to run the saw before with an attempt at cleaning the original piston. ...saw cut well but would not idle after WOT...so tried a gasket kit in the carb....same thing so my assumption (a!# of you and me) was a new piston. ..thanks chainsawr fast & perfect as always. So new piston/ring and same thing.WTF ..During all of this I stole another well used 5105 but mechanically great...so got it and it runs perfect so a quick carb swap and ....wammo! The saw I had been working on runs perfect....so had anyone had trouble with these zama c1q dm14's? The good one I have has 01a under dm14 & the bad has 94a. .... any thoughts?  The single wep seal is not leaking .... and while I'm here..The used 5105 went through about 2 1/2hrs of semi dry hedge cutting after being converted to 3/8 050 20" bar and WOW! Great saw. Was working to bury the 20 but didn't quit....As fast as the not working hard 6400 I have with same 20" chain
