What the notice says かじ取り装置において、原動機からの動力を旋回用静油圧変速機に伝える入力軸の位置決め用スラストカラーの強度が不足しているものがあり、入力軸にプーリーを固定する際にスラストカラーが破損する場合がある。そのため、プーリーにガタが生じ、そのままの状態で使用を続けると、キー溝部が摩耗し、プーリーが破損して左右輪の速度差が生じなくなるため旋回できなくなるおそれがある。

What the ministry says is wrong

かじ取り装置において、原動機からの動力を旋回用静油圧変速機に伝える入力軸の位置決め用スラストカラーの強度が不足しているものがあり、入力軸にプーリーを固定する際にスラストカラーが破損する場合がある。そのため、プーリーにガタが生じ、そのままの状態で使用を続けると、キー溝部が摩耗し、プーリーが破損して左右輪の速度差が生じなくなるため旋回できなくなるおそれがある。

What is to be done about it

全車両、キー溝を点検し、キー溝が摩耗していた場合はプーリー、軸、キー、止め輪、オイルシール、座金を新品に交換する。また、全車両、当該スラストカラーを対策品に交換し、ナットを適正なトルクで締め付ける。

The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered. CarsMultiverse is not the ministry and not a safety authority. To act on this notice, use the ministry's own document.

The Japanese register on this site

ヤンマー elsewhere in this register

ヤンマー is named on 113 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: その他(かじ取り)

87 notices in this register name その他(かじ取り). A defect that keeps returning under one heading is worth reading as a group rather than one notice at a time.

Reading this against the source

This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.

This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a Yanmar: 114 in the register, and 303 Japanese vehicle recall notifications filed in 2011.
