Pushrods was my guess.  Cam cover would not matter and there are no o-rings between the head and rocker support on the bullet TP Rocker box.  The rocker support is part of the box and the oil seperator/breather is very different than stock.


Scott, is there a reason you went with Cycle Rama roller rockers instead of the TP engineering ones?

yep...pushrods vs. lifter covers...

I had already bought the Cycle Rama roller rockers prior to deciding on the TP rocker boxes...(Cycle Rama supplied the cams, lifters, roller rockers, did the head work, ect.)

Thanks for taking the time to take pictures and share with us.

Great walk-thru and pics Scott.  Wish I had the patience and the ability to do something like that myself.  This has been a very enlightening trip through the re-building of the top end of one of our beasties.  I'd like to see a vid of the new build running also.  Thanks. 
Cheers ,

Great job Scott!

I'll head over to the shop today and try and get the map out of my bike for you.

Hoist!

Your pretty much got it...I could not install the pushrods with the lifter covers installed - there was not enough clearance.  I had to take the lifter covers back off and install them with the pushrods...lesson learned.

With the rocker supports being all one piece with the rocker boxes I'd wondered if "easy install" adjustables would still go in or not.  Mine are adjustables, but not quick install.  So I knew I'd need the extra room anyway.  These rocker boxes just add a few quirks of their own.  I'll just have to remember to stick the pushrods in before the pipes go on to have that bit of extra room taking the lifter blocks on and off .

Why not put them loosely in place before you bolt the head on, like a 1-piece pushrod. Adjust them after assembly, and close it up w/2-piece PR covers. You don't have to worry about the lifter blocks that way either.

Howie, I'd planned to try precisely that.  Set the pushrods down through the heads and set the entire rocker box/rocker arm assembly down over the top.  If it'll work without taking the extra bits apart down low that's great.  Just don't know yet if it will.

Front hole will obviously allow plenty of room.  Don't know if back hole will though.  One of those "just have to try it and find out" kind of things.  If not popping off a lifter block is no big deal for an extra.

113 vs EVO

Is this a 113" Cylinder or a 110" cylinder compared to an EVO?  There is very little surface area on the non evo cylinder for a head gasket to seal.

Maybe I'm missing something here, but it seems this is making it harder than it is!  The TP rocker boxes allow the rockers to come out easy.  What I do is set the rocker boxes down on the heads with out the rockers.  Bolt everything down, put in the tubes and drop the pushrods in.  Then I put the rockers on.  With the TP's, if you have to pull the pushrods, I just take out the one bolt holding the shaft and pull the shaft out, leaving all the other bolts in.  There is a screw hole in the end of the TP rocker shafts that make it easy to pull it in and out.

Perhaps the problem is you did not use the TP engineering rockers and the shafts supplied did not have these screw holes?

Another big problem I see with the TP rocker box is the supplied grade 8 bolts used for the rocker shafts, they are shorter than the stock ones.  You run a good risk of stripping the holes in the head with these bolts.  I replaced mine with allen head bolts the same length of the stock ones.  They are a good 1/2" longer than the ones TP supplies.

Another thing to watch out for with these rocker boxes is they are taller than stock.  I had to shim my rear gas tank support up to clear the rear box.

Quick install pushrods go in without any problems.

It would not seem to me there would be clearance to pull the rocker shaft retaining bolt on the rear cylinder...between the rocker box and the frame???

There are a number of sequences of assembly that will work...you just have to know there is an issue.  I made the mistake of assuming the S&S adjustable pushrods would shorten enough to be installed after the rocker boxes had been installed and after the liifter covers were installed - which turned out to be a wrong assumption.  Once I got that far, the simple solution was to pull the lifter covers back off...like I said...lesson learned.  In hingsight, I would have slid the pushrods in place prior to assembling the rocker box to the head.

For someone only wanting to change cams (and leave the top end together) pulling the lifter covers would be the least amount of work.

Regarless of the sequence you used to assemble this motor we want to know when it's running.
You have done a great narration on the assembly and we are ready for it to run!
(and I'm sure you are also)
Good job buddy!

thanks for the comments...

I am picking away at it...Got the electrics hooked up and gas tank on yesterday...  Still have to get the exhaust on, button up the primary and a few odds and ends.  Hopefully I will get some time today and/or tomorrow to finish it and fire it.  You are correct, I am anxious to hear it run!!

Just like watching the Discovery Channel.  Nice job.  Good luck, hope is meets or exceeds your wildest expectations for performance and reliability.  Doing it yourself is awesome.     I'm jealous!

[IslandUltra]

Wow, I just finished going through this entire thread.  It was very educational for me.  Let me be another person to say it is awesome that you have the ability to so this yourself.  Thanks for sharing.
