YXZ1000R Bearing Selector β Rod & Main
Enter the codes stamped on your crankshaft, connecting rods and lower crankcase. We'll show the Yamaha bearing color for each position (per the Yamaha YXZ1000R service manual) and add 2 halves per position to your cart.
Where to find your numbers
1Crankshaft pin numbers P1βP3 (3 digits)Numbers “A” stamped into the crankshaft web. The 3-digit group, read left to right = P1 P2 P3 (e.g. 334). P1 = cylinder #1 (front), P3 = cylinder #3 (rear, AC magneto side). Service manual p. 5-75/5-76.
2Connecting rod numbersNumbers “B” stamped on the connecting rod big end (e.g. 6C). Use only the number (6). Rod for cylinder #1 goes with P1, #2 with P2, #3 with P3. Service manual p. 5-75/5-76.
3Crankshaft journal numbers J1βJ4 (4 digits)Same crankshaft web: the 4-digit group, read left to right = J1 J2 J3 J4 (e.g. 4444). J1 is the front journal (cylinder #1 end), J4 the rear (AC magneto end). Service manual p. 5-82/5-83.
4Crankcase (lower) numbers (4 digits)Numbers “B” stamped on the crankcase (lower). Type them exactly as stamped, left to right. The manual shows them as J4 J3 J2 J1 (reversed) and we un-reverse them for you. Service manual p. 5-83.
Diagrams: Yamaha YXZ1000R service manual (LIT-11616-30-21). Cylinder numbering: #1 front, #2 middle, #3 rear (p. 3-4). Clean the stamps and read them in good light. 6, 8, 3 and 5 are easy to mix up.
Heads up: Selecting crank and rod bearings is a technical process. This selector assumes you can read the factory codes correctly and will verify oil clearance with Plastigauge before final assembly. If you aren't comfortable or familiar with this process, please call us at 920.498.1223 (Option 2) before you order. Dirt Launch Powersports is not responsible for incorrect code readings or bearing selections.
Rod bearings
Cylinder #1 = front, #3 = rear (manual p. 3-4). Enter 6 or 6C.
