Replacing both at the same service avoids a repeat job shortly after.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What causes trim cylinder failure on DPH\/DPR drives?\u003c\/strong\u003e\u003cbr\u003eA: The most common causes are corrosion on the piston rod (especially in saltwater environments), seal wear from age or contaminated hydraulic fluid, and physical damage to the rod or mounting points. Regular anode service and keeping the hydraulic fluid clean extend cylinder life.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThe most important distinction with this part is side and serial range: 22121309 is the port-side cylinder, and for DPH-D1 drives it applies from serial A395817 onward — earlier drives used 21840807. Always confirm side and serial before processing the order. If a customer is replacing one cylinder due to a leak, recommend inspecting the starboard cylinder at the same time. Also check the hydraulic hoses and fittings while the drive is apart — a cylinder replacement is a good opportunity to address any hose wear before it becomes the next service call.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563991171108,"sku":"22121309","price":1026.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/5c14affe-e98d-41f2-886c-4aecab909549.png?v=1787451220","url":"https:\/\/marisolmarine.com\/products\/volvo-275","provider":"Marisol Marine Company","version":"1.0","type":"link"}
