The picture contains several pistons, but it does not define how many pieces are sold in a package. Before calculating freight or comparing prices, request the exact piece count and ask what the packed-weight figure represents. Do not interpret it as the shipping weight of one piston without that check.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The stated product envelope is 86 \u00d7 86 \u00d7 72 mm, with a package of 330 \u00d7 240 \u00d7 130 mm. Those values are initial listing information. The page separately asks for the piston reference, bore, compression height, pin bore and ring-groove details. The engine-specific matching dimensions should come from the correct drawing and workshop specification, rather than from the outside envelope alone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Confirm whether rings, piston pins and retaining clips are supplied with the piston. A single-position repair and a complete engine-set order need different quantity controls. Preserve the removed piston&#x27;s markings and the associated liner or bore <a href=\"https:\/\/emtoolbox.nist.gov\/faq\/faq.asp\" target=\"_blank\" rel=\"noopener\">\u0111o l\u01b0\u1eddng<\/a>. The final order should identify the matched components and sales unit in a way the warehouse and workshop can both verify.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"preserve-damage-evidence-before-selecting-the-repair\">Preserve damage evidence before selecting the repair<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Skirt scoring, crown damage, broken ring lands and discoloration are different observations. Record the affected cylinder position and preserve the old rings and pin where relevant. The workshop should investigate lubrication, cooling, combustion and mechanical interference according to the damage pattern. A new piston does not remove the need to understand the condition of the cylinder and related parts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Assess the liner or bore, ring specification, connecting rod and pin arrangement as part of the repair. Do not choose a repair size without a coordinated measurement and machining plan. Universal ring-gap or clearance figures are inappropriate across different engine versions. The order should identify the final piston reference, required quantity and associated components after the workshop has established the repair specification.<\/p>\n\n\n\n<h2
