Note: There are two possible chain configurations for the engine. Both configurations use a unique chain link to line up with the intake side balance shaft sprocket timing mark. The first design uses a unique link colour (1). The second design uses a black anodized link (3) with uniquely coloured links on either side (2).
- Determine the configuration of the balance chain.
Note: If the balance shafts are not properly timed to the engine, the engine may vibrate or make noise.
- Install the balance shaft drive sprocket.
- For the 1st design balance chain, install the balance shaft drive chain with the coloured links lined up with the marks on the balance shaft drive sprockets and the crankshaft sprocket. There are three coloured links on the chain. Two links are of matching colours, and one link is of a unique colour. Use the following procedure to line up the links with the sprockets:
| 3.1. | Orient the chain so that the colored links are visible. |
| 3.2. | Place the uniquely colored link (1) so that it lines up with the timing mark on the intake side balance shaft sprocket. |
| 3.3. | Working clockwise around the chain, place the first matching coloured link (2) in line with the timing mark on the crankshaft drive sprocket, approximately 6 o'clock position on the crank sprocket. |
| 3.4. | Place the chain (3) on the water pump drive sprocket. The alignment is not critical. |
| 3.5. | Align the last matching colored link (4) with the timing mark on the exhaust side balance shaft drive sprocket. |
- For the 2nd design balance chain, install the balance shaft drive chain with the black anodized links lined up with the marks on the balance shaft drive sprockets and the crankshaft sprocket. There are three timing links with a black anodized finish on the chain. One black anodized link has uniquely coloured links on either side. Use the following procedure to line up the links with the sprockets:
| 4.1. | Orient the chain so that the colored links are visible. |
| 4.2. | Place the black anodized link (1), with uniquely coloured links on either side, so that it lines up with the timing mark on the intake side balance shaft sprocket. |
| 4.3. | Working clockwise around the chain, place the next black anodized link (2) in line with the timing mark on the crankshaft drive sprocket, approximately 6 o'clock position on the crank sprocket. |
| 4.4. | Place the chain (3) on the water pump drive sprocket. The alignment is not critical. |
| 4.5. | Align the last black anodized link (4) with the timing mark on the exhaust side balance shaft drive sprocket. |
