23 clutch 離合器
1 Cork is used as the friction material in the inserted clutch plates. When the inserts become worn, the clutch will slip, even if cluth adjustment is correct.
軟木是作為摩擦材料中插入的離合器片。當插入變得破舊，離合器將打滑，即使離合器的調整是正確的。

2 Each inserted plate should have a thick ness of 3.5mm(0.138inch). The wear limit is 3.2mm (0.126inch). If the plates have reached the wear limit, they must be replaced

每個插入板應該有一個 3.5毫米厚的內斯（0.138inch）。磨損極限是3.2毫米（0.126inch）。如果該板塊已達到磨損極限，他們必須更換

3 Measure the free length of each clutch spring, because they will take a permanent set after an extended period of service. The free length of a new spring is 47.5mm(1.87inch). Replace ALL the clutch springs if any spring reached the serviceable limit of 45.5mm(1.79inch).

測量每個離合器彈簧的自由長度，因為他們將採取長期保固。新彈簧的自由長度是47.5毫米（1.87inch）。低於維修界線45.5毫米（1.79inch）則更換所有的離合器彈簧。

4 Check also that none of the plates, either plain or inserted, is buckled. Replacement will be necessary if the plates do not lie flat, since it is difficult to straighten them with any success.

檢查還每一個離合器板，無論是平滑或補充的。如果不平滑必須替換，因為這是弄正難以理順與任何成功

5 Check for burrs on the protruding of the inserted plates and/or slots worn in the edges of the outer drum with which they engage. Wear of this nature will cause clutch drag and other troubles, since the plates will not free fully when the clutch is withdrawn,. A small amount of wear can be treated by dressing with a file; more extensive wear will necessitate replacement of the parts concerned

檢查插入板伸出部分的毛邊和/或在縫隙邊槽磨損的外鼓與他們囓合。這種性質的磨損會造成離合器拖動和其他麻煩，因為離合器被撤回時離合器盤不會釋放。少量磨損是可以靠銼刀加工修理的，更廣泛的磨損，將需要更換令人擔憂的部件。

6 if the machine has covered a considerable mileage, it is possible that play will develop in the clutch housing, producing a mysterious rattle in the region of the clutch. This play develops in the axial direction and can be checked by pulling and pushing on the clutch. It can be reduced by grinding down one end of the spacer bush on which the clutch outer drum seats, taking care to remove only a little metal at a time.

如果機器已經走過了相當大的里程，它有可能會磨損離合器外鼓(澳打)得受力位置.在離合器外鼓上產生詭異的波浪狀痕跡。這個刻痕會在軸動正向逐漸出現，可以推動與反向拉動,來檢查離合器。它可以減少磨下來的一端步行間格上的離合器外鼓，一次只小心的去除一點少許的金屬。

7 Check that clutch operating mechanism in left-hand outer cover works quite freely. Mechanism operates on quick start worm principle.

檢查離合器在左側引擎外殼蓋的運作機制自由無礙。機械的運作工作效能快速。
