Triumph 650 rocker boxs

[@RobertJones-fq9dk]

Wow! So much simpler than the workshop manual method! I went to the trouble of building the alignment bar the manual recommends and still was struggling. I just used this method and it went together on the first try! A big time thank you to Richter Machining!

Hi; as you may know, the 750s have spindles with a groove; arms with notches and the spring washers go to the box (!) The manuals still show this way but the later parts books show the new way. All designed by BSA engineers so the guys at Meriden continued doing like with the 650s...

Great channel. Thanks for making these videos. They are quite helpful. Keep up the good work.

The spring washers were put in by triumph because their machining was a bit slap happy. Quite a few of my friends and myself buy a few extra flat washers and delete the spring washers to eliminate rocker float. Alsoe we get alloy gaskets and use a really thin smear of 3 bond on both sides. They are great and zero shrinkage , no leaks. Your motor is looking good.

...hello; that way you do not gain anything except a tiny fraction of power in a full racer. Actually what you gain is more mechanical noise. Think about it

I too have read the service bulletin Here is how it reads. Assembly Order of Spring Washer The picture in the Parts Books show wrong order of assembly. ANY Triumph engine which uses this new method of lubrication to rocker ball ends MUST have plain flat washers assembled next to the rocker arm. When correctly assembled, spring washers will be separated from rocker arms by the flat steel washers. The rocker ball ends could have insufficient lubrication if spring washer is assembled next to the rocker arm.

That's my understanding too, the opposite of in this video. I'm tempted to run inlet one way and exhaust the other, and see if there's any appreciable different after a few thousand miles

I may be weird but I like this content

[@jamesschara2489]

Really good information. Did I miss where you can purchase the o ring installation tool?

[@fretzmaler7591]

Hey, Nice info but what about fit those rocker box washers on a T140 where spring washers is installed towards rocker box because of laye not hed rocker arms to maintain oil pressure and lubrication to pushrods and valve stem top. Which way to go?

[@daveco1270]

Did triumph assemble these originally with the spring washer against the edge of the rocker box? I thought there was a bulletin after the fact telling people to swap the spring washer and the flat washer around because the aluminum was getting chewed up like you said.

[@daveco1270]

Good tips. Thank you. I haven't taken my rocker boxes off my TR6 so I dont know if the washers are in the correct order. When I have a reason to take them off I'll check. I'm going to unscrew the two dome nuts at some point and replace them with some shiny news ones. Any trick to keep the spindle from spinning when I loosen or tighten that nut? Or do I just pray the dome nuts come off and go back on without issues?

[@dirtyshirtrichter8647]

if they slip and are loose it may be time to replace the O ring on the left end of the spindle they should help keep is snug but most are tight fit as is

[@daveco1270]

@@dirtyshirtrichter8647 thanks. I replaced those acorn nuts yesterday and didn't have a problem getting the old ones off or the new ones to tighten back on.

hi richter how do feel about valve stem seals on intake valves, thanks dons engs

[@dirtyshirtrichter8647]

i run them on all the heads i do

[@pauliebots]

Did you vapor blast the rocker boxes ? If you didn't ,how'd you do it? Thanks for this.

[@dirtyshirtrichter8647]

yes sir
