Title: Why is the clutch pushrod tapered/narrower in the middle? Post by: LowercaseJake on July 24, 2017, 12:53:56 AM Asking for a friend who's machining titanium replacements.
I have a few guesses buy they are just that, guesses. 1 - the rod passes through the guts of the engine. The taper is necessary for either proper oil flow, avoid moving parts, or both. 2 - the taper is necessary for the o-ring oil seals to perform their job for reasons that make sense in my head but can't explain. 3 - weight savings 4 - the rod is a retrofit for preceding rod part numbers, and the taper is necessary for it to retrofit. 5 - I could do this all day, so I'm going to leave it to the people who actually know. Thanks! P. S: If you're interested in a Ti pushrod, let me know and I'll pass along his information. He'll also be manufacturing the end pieces, ala the STM part and the unfortunately discontinued Motowheels part. Title: Re: Why is the clutch pushrod tapered/narrower in the middle?

I believe from my memory of looking at oil passages and flow through the engines that it narrows to allow oil flow from one part of the transmission to another. |
