Yanmar YT463 2015–2017
Yanmar YT470 2015–2017
Hazard
The exhaust pipe mounting bracket attachment structure to the engine is improper, resulting in some units being forcibly assembled with the exhaust pipe bracket mounting holes misaligned with the exhaust pipe bracket mounting holes. Consequently, engine vibration causes the exhaust pipe to deflect, subjecting the bracket attachment point and exhaust pipe bracket attachment point to excessive stress and damage. In the worst case, cracks may develop in the exhaust pipe, causing exhaust gas leakage.

排気管をエンジンに固定する排気管ステーの取付構造が不適切なため、排気管ステー取付穴が排気管ブラケット取付穴と合わない状態で無理に組み付けたものがある。そのため、エンジンの振動で排気管が振れてステー取付部及び排気管ブラケット取付部が過大な応力を受けて損傷し、最悪の場合、排気管に亀裂が生じて排気ガスが漏れるおそれがある。
Remedy
Replace the exhaust pipe bracket and exhaust pipe with corrected parts on all vehicles.
