鳥嘴的車最近一次換機油,發現機油是用噴射出來
感覺引擎內部變成「正壓」,懷疑是單向閥或橡皮管已積滿堵塞
原來這個單向閥直到今日也安裝了四年多近五年了
從來沒拆下來清潔保養,MSX里程四萬多公里
長距離出遊跟通勤小車車

鳥嘴弟開始檢查

先從好拆的單向閥下手,管子有點緊呢

把二邊的車殼都拆下比較好施工,因為單向閥想換個位置安裝
羽山懷疑是不是因為這位置太低,假如有機油的油氣上來,最後都會積在單向閥的上半部
長久之後越積越多就造成開閉不良,氣體一直在推一整團的油

單向閥

之前安裝的位置在這

拆下單向閥 手捏的這條橡皮管也可以拔出來,等會用風槍吹一吹

好了

單向閥構造很簡單,可以分解清潔

照片糊糊

油泥有點多

單向閥裡的塑膠支架也可以拆下來清一清

風槍吹一吹,布擦一擦

構造很簡單

清潔完成,重新組裝,用嘴吹吸確認功能正常

從呼吸管裡吹出不少油膏

定期清潔也是很重要

單向閥安裝的位置想換個地方,我個人是比較推薦靠近空濾盒
來到機車的左側

找到呼吸管接到空濾盒的位置

如圖所示,紅色箭頭這條是呼吸管,等會單向閥重新安裝在這裡
這樣油氣上來比較不會積在管子裡,會回流回曲軸箱,超過單向閥後就會掉到空濾盒下面
集油集水管,方便拔起來清潔

手摸的這條是呼吸管

約中間的位置剪 2cm

裝上單向閥,另一頭就繼續接回空濾盒
注意箭頭要朝空濾盒

補一張閃光燈

插上管子,束環裝好

空濾拆下來吹一吹再裝回

拿出 8mm 插芯銅管

原本裝單向閥的地方把管子接回復原
單向閥危機解除

接下來弄醜醜的頭罩

拆下改裝頭罩

改裝頭罩掉漆很嚴重,醜醜的拆下來修,左下也有個裂角

裁砂紙磨一磨

磨

大平面

磨磨磨

這裡也有個傷口

磨磨磨

處理裂開的地方

另一面

剪一小段金屬網

熱融槍加熱金屬,壓入

壓融

壓,不是很好操作

感覺不是很好的方法,殼有點變型,以後還是用 ABS 膠吧
還好壓一壓有救回來

準備上漆

消光黑第一層

二層

三層,上金油

好了,微乾,裝回車上

完成
後記:
MSX 安裝單向閥,最好定期拆下橡皮管吹一吹,避免裡面積太多油造成單向閥堵塞,比較好的作法
還是把單向閥移到上半部,讓油水有機會回油引擎,或流入空濾盒,
如果換機油時發現機油用噴的,就要馬上處理,以免引擎變成正壓容易造成油封炸裂
定期保養的項目
