Auto-craft valve train....what would you do?

[norris]

It's just the oil on top of the edge of the retainer.....they fit perfectly

Well, I cannot get a good measurement with a dial gauge on the left side....to many oil cooler/filter hoses. I could take them off, but I'll have the right side temporarily back together tomorrow night and I'll do it then.

Did get the oil pump back on.....no leaks, but then again, there's no pressure 😉. I'll wait on reinstalling the headers and tins until I can measure valve and cam lift at the adjusters. Sure would have been nice to find some info on the cam!

Got my Autocraft valve train back together tonight. The new bearing was a little different than the original but it pressed into the rocker arm fine and fits the shaft like the originals.
I adjusted them up, made some lift measurements and sent them to Jeff. He believes the CB 1.3s will fit just fine....so I'll order them tonight. The cam appears to be similar to an Engle 100.

I have to say that I do wish the Autocrafts had worked out just to keep it all old school. I just can't risk more rocker arm bearings coming apart.

I'll report back after I get the CB 1.3s installed and running.

Thanks for all of the advice and a special thanks to Jeff.....I'm learning a lot fast....hopefully I can "pay it forward" someday!

Its easy to help people that work hard with only requesting the information necessary.

There are so many people that type questions all day without putting effort to check anything(not even using search function). They just sit back at the keyboard all day waiting for others to do the work for them.

Gotta love a guy like Norris, takes a tiny bit of info and working like crazy to find a way to make things work and do it right.

That cam has the effect of a 110 with 1.1's, CB2236 with 1.25s, and could even be a cam like a FK7 that was meant for 1.4's, but for some reason got 1.25s.

If you wanted to be double sure about everything, you could adjust your intake about .020-.025 past zero effectively giving your cam that much more lift to match the 1.3's, and ever so slightly turn the engine over at the crank pulley making sure you have piston/valve clearance.

So, I would add .025 to my loose zero lash adjustment on an intake valve....then slowly turn the engine over at the crank, feeling/listening for piston to valve interference with intake valve at full lift and piston at the top of compression stroke?

[jpaull]

Yes, slowly and carefully😊😊

Jeff, I added .025 to the lift at the adjuster....slowly/carefully turned the crank until the valve was fully lifted and the piston on top of the compression stroke and there was no interference between valve and piston.

Dan, there are 8 big fins on my heads.

[norris]

Cool....thanks Dan

[jpaull]

Awesome,

You have some piece of mind, and did all the checking possible without pulling the engine apart. You should be AOK

The CB 1.3s are on their way.

[norris]

Not to beat a dead horse, but I forgot to post a pic of the cam gear.
Anyone know who built the cam gear?.....might lead me to who built the cam

[oldschool5er]

It is a Dial-in Cam no longer made. Bob Walters patent. He also modified other manufactures Grinds to fit his gear. W3700 does not conform to the Dial-in-Cam catalog I have. Yours has been set at 1 deg advanced but can be set up to 4 deg advanced, or at Zero straight up, or up to 4 deg retarded.

I forgot to add this but maybe you can use it in the future. Bob made several versions of the gear other than stock. He made a 15 deg Helical instead of the stock 20 deg helical which allowed less thrust on the cam bearing, this was before straight cut tooth gears we have now do similiar thing. His 15 deg cam used a matching 15 deg crank gear. He also had a narrow gear version and a center groove cut gear. You would not be able to tell what exact config you have now but for in the future you might want to make a note of it if the cam was still good enough to save.

I've made notes on this in my "book".
Appreciate it oldschool5er

older timers simply used to use 36hp cam/crank gears for less thrust (less gear pitch), when the gear sets were virtually free.

At Aircooled.Net we even sold them in sets for around 10 years before we ran out of our stock.
