So I did some searching and found out that I have the common split nylon actuator. What is the best fix for this? I did see the rd-350 fix. What is recommended by you guys in the know? Been there done that?

Yes i did that to one of mine. Was a lifetime ago but still using it. Struggling to remember how i did it but i know the cap sits out a few mm so i'd guess i fitted it through from the outside. Then again maybe not as doubt you'd end up with enough sticking through the inside. I'll have a look next time i'm near it. Works well though. In hindsight i think i have to keep the cap screwed on to retain it so must be from the outside in. Would've just bored away till old worm was no more & new one fitted in . Bought a couple of others since then but no covers to fit them in, need about 3 covers as keep swapping one around for the bike flavor of the day. I'll just get some heavy alloy plate with a hole in it to just make a simple thing to hold the actuator--one day!!.

Scott,
Another option is new reproduction actuator, here's one at $80.
Good Luck!!

Scotddove,

I did the 'replace with R-5 actuator', which requires some minor machining of the cover, but is a permanent fix. It's available on here as well. You can find it and pictures at "push lever assembly DT1, #8" on this site. Hope this helps! Oh, to save you time, it's all shown below...

From subject post:

I found these a bear to find at this time. SO, I permanently modified (minor machining and drilling and tapping of two holes--see above) my countershaft cover to accept a stock clutch actuator from a circa 1975 Yamaha R-5. It's design makes it impossible for the plastic worm gear to crack and stop functioning as this uses a METAL worm gear, operating INSIDE of a plastic housing that is kept intact by a metal covering. Once done, you never need worry again, and it looks stock from the outside.

RT325,

Try this: "You can find it and pictures at "push lever assembly DT1, #8" on this site." The pictures show up there, too.

Found my pics, not too good but can see i put it through from the outside. RD350 type, probably RD250/400 in hindsight but the same horse. Think i did it that way because it got a bit close to the sprocket--cant remember. Obviously had a plan at the time, just not obvious why now lol.
