The 1.75\" suits later and larger center bore flywheels.\u003c\/p\u003e\n\u003ch3\u003eWhat this part is\u003c\/h3\u003e\n\u003cp\u003eThis is the \u003cstrong\u003eadapter that carries the pilot bearing\u003c\/strong\u003e, sized to your flywheel center bore. It is not a complete pilot bearing housing assembly. The bearing itself is a custom 32mm OD × 16mm ID true rolling bearing — ASE has these made specifically because a 32×16 bearing is not manufactured for the CD009 application. The 16mm inner diameter is what allows it to run on the CD009 input shaft.\u003c\/p\u003e\n\u003cp\u003eAll current ASE pilot bearings are true rolling bearings, superseding the earlier solid one-piece design. Product images reflect the current version.\u003c\/p\u003e\n\u003ch3\u003eBefore you blame the adapter — check your transmission bearing size\u003c\/h3\u003e\n\u003cp\u003eIf a pilot bushing adapter has been destroyed prematurely, the adapter is usually not the cause.\u003c\/p\u003e\n\u003cp\u003eThe CD009 comes with one of \u003cstrong\u003ethree main input shaft bearings depending on year — 90 mm, 95 mm or 100 mm\u003c\/strong\u003e. Every ASE adapter plate is cut for the 100 mm, which is by far the most common.\u003c\/p\u003e\n\u003cp\u003eInstall a plate against a 90 mm or 95 mm bearing and there is visible play in the bore. The shaft moves radially inside that gap continuously, which causes noise, tears up the input shaft bearing, and \u003cstrong\u003eprematurely destroys the pilot bushing adapter\u003c\/strong\u003e. The adapter is absorbing movement it was never designed to take.\u003c\/p\u003e\n\u003cp\u003eThe fix ships in every current CD009 kit: \u003cstrong\u003eprecision laser cut bearing rings\u003c\/strong\u003e that convert a 90 mm or 95 mm bearing up to 100 mm. The thinner ring handles 95 mm, the thicker one handles 90 mm. They pop straight on with no fitting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMeasure your bearing OD before installing the plate.\u003c\/strong\u003e It takes thirty seconds and prevents a teardown.\u003c\/p\u003e\n\u003ch3\u003eFull explanation\u003c\/h3\u003e\n\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin-bottom:1.5rem;\"\u003e\n\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/yGOi73ojIAY\" title=\"You Killed Your Pilot Bearing...Here Is The Fix\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen loading=\"lazy\"\u003e\u003c\/iframe\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003ca href=\"\/blogs\/news\/cd009-bearing-sizes-why-your-pilot-bushing-failed\"\u003eRead the full write-up on CD009 bearing sizes →\u003c\/a\u003e\u003c\/p\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Is this the complete pilot bearing assembly?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. This is the adapter that carries the pilot bearing, sized to your flywheel center bore. It is not a complete housing assembly.\"}},{\"@type\":\"Question\",\"name\":\"What size is the ASE pilot bearing and why is it custom?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"A custom 32mm OD by 16mm ID true rolling bearing. A bearing in that size is not manufactured for the CD009 application, so ASE has them made specifically. The 16mm inner diameter is what allows it to run on the CD009 input shaft.\"}},{\"@type\":\"Question\",\"name\":\"Which size adapter do I need, 1.65 inch or 1.75 inch?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Measure your flywheel's center bore. The 1.65 inch fits flywheels from other brand kits and ASE flywheels made between 2018 and November 2025. Always measure to confirm before purchasing.\"}},{\"@type\":\"Question\",\"name\":\"Is this the same as the older one-piece pilot bushing?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. All current ASE pilot bearings are true rolling bearings, superseding the earlier solid one-piece design.\"}},{\"@type\":\"Question\",\"name\":\"Does the pilot bearing differ between a JZ swap and an LS swap?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. The CD and JK transmissions use the same input shaft, so the pilot bearing is the same regardless of which engine kit you are running.\"}},{\"@type\":\"Question\",\"name\":\"Why did my pilot bushing adapter get destroyed?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Almost always a bearing size mismatch rather than a fault in the adapter. The CD009 comes with a 90mm, 95mm or 100mm main input shaft bearing depending on year, and ASE adapter plates are cut for 100mm. Installing a plate against a smaller bearing leaves play in the bore, and the resulting radial movement causes noise, tears up the input shaft bearing, and prematurely destroys the pilot bushing adapter.\"}},{\"@type\":\"Question\",\"name\":\"What bearing sizes does the CD009 use?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Three, depending on the year of the transmission: 90mm, 95mm and 100mm main input shaft bearings. The 100mm is the largest and the most common, and is the size every ASE adapter plate is cut for by default.\"}},{\"@type\":\"Question\",\"name\":\"What if my CD009 has a 90mm or 95mm bearing?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Use the precision laser cut bearing rings that ship with every current ASE CD009 kit. The thinner ring converts a 95mm bearing to 100mm and the thicker ring converts a 90mm to 100mm. They pop straight on with no fitting or shimming required. If your kit predates this feature, the rings can be purchased separately.\"}},{\"@type\":\"Question\",\"name\":\"Should I keep the bearing rings if my transmission is already 100mm?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. Store them safely. When a CD009 eventually fails, the cheapest replacement is usually another used CD009, which may have a 90mm or 95mm bearing. Having the rings on hand means the solution is already in your possession rather than something to discover mid-build.\"}}]}\u003c\/script\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"VideoObject\",\"name\":\"You Killed Your Pilot Bearing...Here Is The Fix\",\"description\":\"Autosports Engineering explains why CD009 pilot bushing adapters fail prematurely — the transmission comes with 90mm, 95mm or 100mm input shaft bearings, and adapter plates are cut for 100mm.
