Thanks for the explanation!
I am still thinking out-loud: with, or without the lock washer, if the locknut failed, then the engine will be damaged eventually.
If the locknut secures the locknut, then what will cause the washer to fail? How likely?
The reason that leads me to this topic, because I don't like to use Loctite inside the engine system. Beside, I don't see the manual says anything about using Loctite at this step. The Loctite may get into the other places. I guess!
Just a logical brainstorm.
The manual doesn't say anything about adding lock washers either. Sounds like a little selective reading here.
Any internal nut or washer in any engine is going to be a machined hardened part. Off the shelf hardware is soft and will fail internally, especially if used on something that moves as much as a pushrod with varying degrees of stress. Use locktite, I think there is a green type for internal engine parts
I think you have a mechanical point.
Thanks for the info.
