Parts manuals place 977911 in shim stacks alongside companion thicknesses 977910 (0.10 mm) and 977912 (0.35 mm), with the final combination selected by measured workshop requirement to achieve the specified setup dimension. Because the same part number appears in both DPH\/DPR drive assemblies and HS1A transmission assemblies, the correct quantity and combination must always be determined from the applicable Volvo Penta workshop procedure for the specific assembly being set up — not assumed from a previous build.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta DPH-A \/ DPH-B — drive shaft\/bearing housing and 1-inch extension-kit assemblies\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPR-A \/ DPR-B — drive shaft\/bearing housing and 1-inch extension-kit assemblies\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPH-D1 — extension-kit assemblies\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPR-D — extension-kit assemblies\u003c\/li\u003e\n\u003cli\u003eVolvo Penta HS1A (all ratios) — reverse-gear transmission setup\u003c\/li\u003e\n\u003cli\u003eVolvo Penta HS1A 1.96:1 — reverse-gear transmission setup\u003c\/li\u003e\n\u003cli\u003eVolvo Penta HS1A 2.62:1 — reverse-gear transmission setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e977911 should be selected by measured shim requirement and exact diagram position, not by drive model alone.

Do not assume the original shim combination will remain correct after replacing bearings, housings, gears, or other precision components — any of these replacements can change the required setup dimension. For DPH\/DPR applications, 977911 typically works alongside 977910 and 977912, with the final combination selected to achieve the specified preload or clearance.\u003c\/p\u003e\n\n\u003ch2\u003eCross-Reference Part Numbers\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM:\u003c\/strong\u003e 977911 (0.15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompanion shims:\u003c\/strong\u003e 977910 (0.10 mm), 977912 (0.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e No confirmed Volvo Penta OEM superseding number identified.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003e977911 is a setup shim, not a generic spacer, and the quantity needed is always determined by measurement — not by a fixed rule. The most common issue is attempting to reuse the original shim combination after replacing a bearing or housing without re-measuring the setup dimension. Any precision component replacement in the DPH\/DPR drive shaft area or HS1A transmission can shift the required shim stack, and assuming the original combination still applies is a leading cause of incorrect bearing preload after service. If ordering 977911 for a full assembly setup, consider ordering the companion thicknesses 977910 and 977912 at the same time so the correct combination can be built on the bench without a second order.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564069290020,"sku":"977911","price":10.4,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/b0b3835c-a3df-4ef6-96bc-0c924ba55884.png?v=1788656822","url":"https:\/\/marisolmarine.com\/products\/volvo-1388","provider":"Marisol Marine Company","version":"1.0","type":"link"}
