PURPOSE:To simplify the assemblying of a PTO power transmitting device into a tractor, by separating a flywheel adapted to be fixed to a crank shaft, into front and rear halves so that an oil damper device is fixed to the front half of the flywheel and the PTO power transmitting device is engaged to the damper device. CONSTITUTION:On assemblying, a front half flywheel 9 is at first fixed onto a crank shaft 21, and is attached with a spring type damper device 10 fitted onto the boss part 12 of the crank shaft, by means of knock pins 28 and bolts 26. Next, a rear half flywheel 11 and a cluch casing 27 are positioned and assembled to the front half flywheel 9 with the use of knock pins 31 fitted in the front half flywheel 9, and are secured thereto by means of bolts 25. Simultaneously, a clutch lever 16, a pressure plate 17, a friction plate 13 and a boss part 14 are secured. After the completion of the above-mentioned assemblying, the assemblying of a clutch housing 1 in which a PTO power transmitting shaft 5, the cylindrical shaft 4 of a travelling clutch, etc. are incorporated, is completed by fitting the shafts 5, 4 and the boss parts 12, 14 together in their splined parts. |
