A decent upgrade is the spiral grooved shafts from later years. Tough to find though. The last ones I did, I simply cut a channel/groove between oil journals to get better oiling under the arms. Seems to have worked. Also have read the thackeray washers shouldn’t go directly against the rocker arms because it allows the oil to just weep down rather than become pressurized under the arms….but who knows? 🤷♂️ I recently took my ‘71 top end apart (after 10 years on the road) and found the thackeray washers did zero damage to the aluminum wall of the rocker. Just my 2 cents and that’s about all it’s worth lol.
That was really interesting and informative, Jared. I don't have a Triumph, but I usually learn something from you by watching your videos. Thank you. Eric in Kissimmee
Maybe a dumb question but is there a trick to unscrewing the rocker box dome nuts? The reason I'm asking is because it seems like the only thing keeping the shaft for turning is the o-ring on the end...which makes me think the shaft would spin if I put a wrench on a 50 year old dome nut and tried to remove it.
Great video, Weems. If my spring and shim are on the shaft the wrong way (aka the original factory way) should I take apart my rocker boxes and flip them around or just leave them alone until I have a reason to be in there?
Obviously that rocker-box has openings machined into it. I guess it's cool you can see the valves operate, but isn't oil going to get slung all over the place or crap get in there?
Well it's sunday ,time to break out a beer and watch my old mate do his stuff !! ,
Peace out ✌
Love your work brother
Thank you so much 😀

Glad you enjoyed it!
Great stuff Weems!!
Glad you enjoyed it!
Not sure if I understood any of what was explained.but I like to see things getting put together.
It always helps to get your hands on things to better understand the process!
@@weemsmotorco very interesting I’m always interested in learning things with my hands.

The dome nuts are only torqued to 22 lb ft so it doesnt take a lot to remove them.
Wouldn’t you want to lightly oil the o-ring before putting it on the shaft?
absolutely
When they send Harley parts to the triumph guy LOL

Great Question. I would not worry about them now. At the next rebuild flip them around.
You forgot to oil the 2nd rocker before install Weems. Just a heads up. Great vid!
Good call!

Great Eye! This setup is for my Born Free 13 Dragbike so it will not see road use and the oiling system is a total loss system.
🤘🏻🤙🏻
Yup!
