P SeekPro Nikasil Cylinder Piston Kit 44mm for Stihl MS251 MS251C MS251CBE MS251CBE-2Mix MS251 2-Mix MS251C-BEQ MS251C-BEQ Z MS251Z Chainsaw PN 1143 020 1203 1143 020 1207

The media could not be loaded.  The new cylinder matched up to everything except the intake manifold.I screwed up and checked the bolt pattern to my mounts/bottom cylinder, and didn't check the bolt pattern to the intake. This cylinder will NOT work for me, so I'll either have to find a different cylinder kit or I'll have to find a 4-bolt patterned intake manifold and re-build the unit using the different intake manifold.Note to manufacturer: i double checked my part number!Your advert page specifies this is a direct replacement for: 1143-020-1203 & ...1207.The number you specified as the "do not order" number is: 1134-020-1201.My cylinder number is 1143-020-1203.I would politely advise you update the "do not use" list to reflect this product number. I included a picture of the servicing invoice from my local Stihl dealer that shows they have it listed as a ....1203.And please, for future sake, toss in a 3rd piston ring simply as " oops" insurance. I only had the 2 it came with and one snapped in my hand before i ever got it anywhere near the cylinder. So i had to order a package of replacement rings that took ANOTHER 4-6 weeks to come in before i could finally put the cylinder together, which is how long it took me to figure out i ordered the wrong cylinder. So I've had a dead chainsaw sitting on my workbench for over 3 months even though i made sure my part numbers matched up.

Worked on ms251 stihl chainsaw.

Rings broke upon installation

Es hat alles gepasst bis Kurbelwellen LagerDie original Lager von Stihl ms 251c sind zu groß und deswegen passt die Deckel nicht mehr!!!Also !!!Schadeeeeee!!!👎

Läuft wie neu

Pendant le montage les segments sont fragiles et se cassent.Après montage avec segments neufs le piston serre sur le haut du cylindre (usinage mal fait et cote non conforme)Ne surtout pas acheterAvis du professionnel ou je fait l'entretien de mes machines : c'est de la fabrication de très mauvaise qualité.Résultat : facture de 450€ pour tout refaire
