- Semicárteres

Air

For semicárteres assembly, once checked the clearances of the axes, we assemble the two primary and secondary axis with the selector drum, as explained on the right crankcase, which is supposed to already have assembled all seals, bushings and bearings. Do not forget to mount the necessary spacers we have planned in the previous setting change.





implementation mechanism

From outside the crankcase insert the shaft of the implementation.






Place washer spring support ...




... and the dock separator mobile gear start.




introduce the pinion, the small ramp leading to move ...




... and tab then said pinion stop, not forgetting to place and tighten the nut and washer that attach outside the crankcase.




We insert the large sprocket implementation, which we note is always geared to 3rd gear pinion on the shaft. In this manner, when you turn the start shaft, the pinion is traveling, meshes with the large sprocket, and it turns the transmission main shaft (check). When you turn the input shaft rotates the clutch. If it is disconnected, move the primary drive and this to the crankshaft, cranking for starting. Therefore, if we press the clutch (clutch) the implementation does not work.




not forget the last thick washer on the large sprocket implementation.







selector shaft
We insert the selector shaft from outside the left crankcase.




For crankcase placed inside the washer ...




... and the circlip from the shaft.



Note that is also threaded stud closed blind motor into the left crankcase. Crankshaft




Once assembled crankshaft bearings, heat your accommodation in the right crankcase. This will make it easy to place the crankshaft in it.




The crankshaft bearing finds no cap on the crankcase, so you can enter freely until its counter friction with the walls of the pre-compression chamber. To avoid this extreme, but as of now we can not focus perfectly the crankshaft, we will only leave a small clearance to rotate freely.





change Closed

We put the two centering bushings and gasket crankcase oil a little, over the right crankcase.




Before closing the housings threading, if not already done so, the closed blind screw them (a stud that is threaded into the crankcase through the left and right, to tighten with a nut from the outside.

Heat the crankcase left for the bearing for the crankshaft (which is mounted on the crankcase right) enter without difficulty.




We put the left on the right crankcase. Have to enter easily without hitting or pushing. Neither should insert tightening the bolts connecting the semicárteres, let alone them being hot. The bend can be desplaneará the board and we will have bundled fat. You are warned.

If not go in easily, it pulls back, reheated and try again.




asparagus Then insert the semicárteres binding. On the left side is placed a nut and O ring to prevent oil flow, and on the right side a flat washer, and nut grower.



we will tighten the nuts slowly, following a cross pattern to avoid damaging the board.

A while after closing the housings retighten the nuts, when everything is already set at room temperature (the aluminum will have contracted something and may be loose).
