上１にル、ピストン抜き作業に手間がかかつていえ。Generally speaking, this is an engine equipped with a secondary parrunner shaft (a pair of balancers). However, with the above structure, when removing the piston, the oil pan must be removed from the crankcase, and the /l thinner case section must be removed. After removing the tatami mat from the crankcase, the rod port must be removed by 1kvs, the crankbin bearing must be removed from the connecting rod F, and the connecting rod and screws must be taken out. wholesale oil pan 2
First of all, it is necessary to install the piston and remove the paranoid case, and it is time-consuming to remove the piston.

てｉる。Balancer shaft 9 is the balancer case part! The rear end (the end on the back page side of Figure 1) of the two-part runner case part 5, which is rotatably supported within the i via a plurality of bearing metals spaced apart in the axial direction, is Multiple connections are made to the ribs 11. The front ends of both Bakunte case parts 5 are shown in Fig. 2 (Fig. 3 n-n).
*MR diagram) As shown in K, a pair of idle gear supporting ribs 12 are connected to each other, and a pair of idle gear supporting ribs 13 (fixed shaft) 13 are fixed to each support 13.
An idle gear 14 is rotatably supported on each of the idle gears 14 . Both idle gears 14 mesh with each other, each mesh with a parandy gear 16, and one (
The idle gear 14 of the left side of the oil pan 2 is connected to the front end of the oil pan 2 (the third
At the right end), an oil seal case 1s is freely fitted.
The front end is 111KKmiml. Idle gear 1
