Picture of my head after piston goes bad.

So, on this head, thing. Do I give the rocker
assembly to the machinist to see what he thinks
about repair/rebuild?

I've heard it is possible to buy a rebuilt rocker
assembly, but it could be expensive.

If ya gotta grunt to pick it up, it's IRON. ...Or ya could just take a magnet to it. /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

Can you say h-e-r-n-i-a? Yeah, it's heavy.
So, guess that it's iron.
Irony is....I really didn't know.

Is that Loctite blue on your finger?

/bcforum/images/%%GRAEMLIN_URL%%/devilgrin.gif

Sorry, Dale. A bit belated, but...nope. That's
not Locktite. It's PVC glue. Kids come over, run
one of these gas powered cars that does a speed, like,
I don't know, like 25mph, or something, and runs into
a sprinkler and had water going everywhere.

I have a hard time thinking about other things when
the TR is sick. Dang.

I'd just ship it off to :

They did a stunning job on my TR3A rocker shaft, for about what the parts would have cost me. I'm still not sure exactly how much they replaced, only the pedestals and end caps were clearly my old ones. The rockers looked brand new although I'm sure they must have just reconditioned mine (but apparently they even put a light plating of copper on them as well as refacing the tips & replacing the bushings). All of the adjusting hardware was new, as was the shaft & springs.

The only quibble I had was that they got one of the rockers back on the shaft backwards; but it was no big deal to pop the cap off and flip the rocker over.

Hmmmm. Do you think that's the kind of thing that
would/could be caught by Forum if I were to post
an adequate picture, Randall?

Hate to ask, but I feel I have to: How much did it cost you? Hope you don't mind my asking.

 

[TR3driver]

The flipped rocker was very obvious; you wouldn't need us to spot it. But I'm sure we could.

It's been a few years ago ... IIRC the charge was around $105 per shaft (I sent them two) plus shipping of around $20 for the pair. But they told me the price in advance (including return shipping) so no surprises. Of course that was for a 4-banger, a TR6 would be more.

Randall: I've finally gotten the chance to follow-up
on the rocker assembly lead you gave me. I like
the looks of these guys in Anderson, CA.

Typo, Randall, but got 'em just the same. Thanks.

Now to another question: I'm considering shipping it
off right away. They will have it just after the 1st
of the year.

Would it be better to have the machine shop check out
the rocker assembly first? Is it wise to just replace
what looks bad (penny-wise, pound foolish?) Is this
something the machine shop can do for me...like, is
this common for them....to build/rebuild a rocker?

Just ship it to them. It's their business, and you will have better peace of mind knowiing it was done right. They will use all the good stuff, whereas the local machine shop may just go with whatever is available to them. (Or, send it to the same place and charge you more for it.)

Oddly enough, both links still work for me. In the past, the redirect from https://www.rockerarms.com didn't work, but they seem to have gotten it fixed now.

It's not like one rocker has moved more times than another; the wear is likely the same everywhere. And the bushings more or less wear into the shaft; so replacing one without the other will accelerate future wear.

Your machine shop likely could do the work, but I would expect the result to be rather expensive. As I said, the folks in Anderson only charged me roughly what the parts would have cost ... your machinist is going to add $60-$100/hour on top of that for however long it takes him to do all those setups on his equipment.

Edit : You can also check for wear yourself quite effectively. Wiggle the rocker tips from side to side; if you can feel any slop, they are worn enough to service (for a rebuild). Look at the tips, where you should see a shiny spot surrounded by 'as machined' metal; should be absolutely flat from side to side and smoothly curved along the axis of the rocker. If you can see or feel any wear, it's ready to service. Look at the flats on the locknuts, if they are rounded or damaged in any way, replace them too. Look at the balls on the adjusters, if there is a pip for the center of the pushrod, they are ready to replace. This ain't rocket science !

Thanks, Randall. They do advertise for a TR6 I think
about $185. Probably closer to 200, time the dust
settles; but, think it would be worth it to know it's
right.
