The chain tensioner access bolt washer should be replaced during service.
Failure to replace this part could lead to oil leaks or dirt and grit entering the engine.
If this part is not replaced you risk stripping out the crankcase thread when overtightening the tensioner bolt in an effort to stop oil leaking.
Dont risk it, just replace it.
