BEARING HOUSING WITH INTERMEDIATE SHAFT DISASSEMBLY/ASSEMBLY PROCEDURE (2 OF 2)
| No. | Procedure | Instructions |
|---|---|---|
| 1 | Checking sealing surfaces | Check both sealing surfaces of bearing housing for damage and cleanliness before installation in the bearing housing. Grind off sharp edges if necessary. |
| 2 | Checking flange bearing of intermediate shaft | Check flange for ease of movement or roughness of bearing; replace intermediate shaft if necessary. |
| 3 | Fitting O-ring | Carefully fit O-ring in the groove of the intermediate-shaft flange. Do not fit twisted. Grease lightly |
| 4 | Fitting chain for intermediate shaft | Put on chain between crankshaft drive sprocket and intermediate shaft drive sprocket. Fit guide rail and tensioning rail. After installation, turn intermediate shaft sprocket slightly by hand in clockwise direction and check whether there is sag in the upper chain area. Check chain installation if necessary. |
| 5 | Prepare intermediate shaft and crankshaft for installation | To facilitate assembly, before installing the complete bearing housing unit in the crankcase half (cylinder row 1-3), connect the crankshaft and intermediate shaft with an O-ring. |
