What the ministry says is wrong
静油圧変速機の走行ポンプに装着されている高圧リリーフ弁の圧力設定及び油圧解放通 路の径が不適切なため、走行中に急な前後進の切り換え操作を行うと、走行ポンプと走行 モータの間の油圧回路に過大な圧力が発生し、走行モータのピストンが折損するものがあ る。そのため、エンジンを停止して再始動した場合、当該ピストンの破片がシリンダ部か ら外れ、走行ポンプからの油圧が走行モータに伝わらなくなり、走行不能となるおそれが ある。What is to be done about it
全車両、走行モータの作動を点検し、破損しているものは新品と交換する。また、全車 両、高圧リリーフ弁を対策品に交換する。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.

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 Komatsu: 297 in the register, and 511 Japanese vehicle recall notifications filed in 2004.
