Model T Ford Forum: Forum 2014: Rajo C35 Rocker Arms
Top of pagePrevious messageNext messageBottom of page Link to this message  By Paul Mc Ginnis Dearborn, MI on Tuesday, April 08, 2014 - 05:17 pm:

I was recently offered a Rajo Model C35 overhead valve assembly. It has 7 of the original rocker arms which are in really nice shape including the stands, shafts, etc. Apparently all eight were there when the current owner put it away but now there is only 7. Is there a source for these-either original or reproduction? Or a modern replacement that can be adapted? It is missing the manifold assembly as well....
Thank you in advance for the info.

I think a rocker from a 50's 223 Ford six will be close enough to work (with some mods).
I'm in the middle of adapting a set of these to a Fronty.
I just checked a Rajo and they're similar except mine has a 7/8 dia rocker shaft so the rocker would have to be bored out from the present .781 dia to .875 dia. (I'm not 100% sure mine's original)
I have four extra rockers.
If you want to try it I'll send one to you free of charge.
How's that for a screamin' deal?
Good luck whatever you do.
Bob

Just thinking...sometimes it hurts.
My Rajo is a BB and I dunno if yours is the same???

day late and dollar short, just last week there was some rajo rockers on ebay. just looking, they seemed to be 1 to 1 ratio because the shaft hole looked centered, and my rajo #31 is offset for 1 1/2 to 1. they did look like the same casting though, and it was not a complete set, perhaps someone here bought them, or write the seller and ask to have your contact info passed along.

I was the seller on EBAY. The rocker arms were off a Model C35 and are 1:1 ratio. The head performs much better if you replace them with the 1:1.5 ratio rocker arms. That is what I did and it worked out very well. I would contact Rockerarms.com in Anderson California (530) 242-1316 ask for Gary. You will need to send him your head and he will fabricate you a whole new rocker assembly at a very reasonable price.

My 223 Ford rockers are 1:1.5.
Clayton...I have a couple extra 223 pushrods.
Don't know if they'll work on orig Rajo rockers.
If it'll work I can send you one.

bob, thanks for the offer, i think i have an old ford 223 here so i'll look to see what they are. i think mine are original, and i could make one on the lathe but it would be fun to have a match, and they are probably at least a little hard.

They're not all that hard.
Definitely machinable.

Thanks for all the replies and great advice. The rocker arms are the 1:1 ratio.It looks like my best bet is to get a full set of 223 Ford rockers and adapt them or send the head to the Rockerarms.com company. Too bad I missed the Ebay rockers, it would have been nice to complete the original set just for kicks.
Thanks again for everyone's help.

why not ask mark to send the buyer your email and request? nothing to loose, and it seems to me there was only about 4 or 5 in the deal so perhaps he does not need them all
