位置決めピンの清掃方法 

How to clean the locating pin

1.本体ケースの回り止めピンを固定しているM5ホロセット:1カ所を少し緩め
 ます。 
 
 
 
 
 
2.位置決めピンを押した状態で回り止めピンをペンチ等ではさみ、抜き取ります。 
 
 
 
 
3.位置決めピンを押した状態で位置決めピンを回し、位置決めリングの切りか
 きから外します。この時、位置決めピンはバネで押された状態になっていま
 すので飛び出しにご注意ください。 
 位置決めピン内部にはクーラント逆流防止のチェックバルブが内臓されてお
 りますので、位置決めピンと同様に中のチェックバルブが飛び出さない様に
 ご注意ください。 
 
 
 
 
 
 
4.位置決めピンと本体ケースのピン穴をウエスで清掃します。 
 
 
5.位置決めピン内部に内蔵されていたチェックバルブを、参考図を基に組み付けます。 
 
 
 
6.位置決めピンに少量のグリスを塗布し、チェックバルブとバネを組み付け、 
 本体ケースのピン穴に挿入します。 
 
 

7.位置決めピンを押した状態で、位置決めアームに開いている穴が本体ケース
 の回り止めピン穴に来るように回転させます。 
 
 

8.回り止めピンの外周に設けている平取り部が、ロックボルトに当たるように
 向けて本体ケースの回り止めピン穴に挿入します。 
 
 
9.ロックボルトを締め付けます。締付けが不十分な場合ATCを繰り返した場合、
 回り止めピンが抜け落ちてATCに支障が起こる恐れがありますので、しっか
 りと締めてください。 
 

ロックボルト 

M5 Set Screw

Slightly  loosen  a  M5  set  screw  at  1  position  that  fixes  an  anti-rotation  pin  on  the  body 
 casing.

Pick out the anti-rotation pin with pliers while pushing the locating pin.

Clean the holes of the locating pin and the body casing with a waste. 

Assemble the check valve in the locating pin as in the figure.

Supply  a  small  amount  of  grease  to  the  locating  pin,  assemble  the  check  valve  and  the 
spring and insert in the hole on the body casing.

While  pushing  the  locating  pin,  rotate  it  until  the  hole  of  the  locating  arm  for  the  anti-
 rotation pin is aligned with that of the body casing.

Insert the anti-rotation pin into the hole on the body casing while aligning its flat with  the 
set screw.

Tighten  the  set  screw.    If  it  is  insufficiently  tightened  and  ATC  is  repeated,  the  anti-
 rotation  pin  may  fall  out  and  hinder  ATC.    Ensure  that  the  set  screw  is  tightened 

Turn the locating pin while pushing it, and take it out of the key way of the indexing ring.  
 Since  the  locating  pin  is  pressed  by  a  spring,  be  aware  of  the  locating  pin  suddenly 
 coming  out.    Since  a  check  valve  is  built  in  the  locating  pin  to  prevent  coolant  flowing 
 backward,  be  aware  of  the  check  valve  suddenly  coming  out  in  the  same  way  as  the 
 locating pin.
