Very Cool Slant 6 Product! Camshaft Button

[RustyRatRod]

Yall, this is cool stuff. This is the type of support we Mopar guys need. Please visit Matt's Ebay store here: Badvert65's Ebay Store

Our good buddy, @Badvert65 is doing the Slant 6 Mopar community a great service by offering some pretty cool and innovative parts for our slant sixes. He sent me just such a product to try and I thought I would give a quick review here. Matt, (@Badvert65) knew I was planning on trying to run a gear drive on my current slant 6 build, so he knew I would need to control camshaft walk. He has come up with these super cool camshaft buttons made from Delrin that simply slip right over the camshaft gear retaining bolt. It comes extra long. What you do is trim it to fit so there is zero clearance between the tip of the button and the cover, with no gasket. Gaskets are generally in the .020" range and once the gasket is installed, the fit is just right. I WAS going to have to get the camshaft drilled for the big block three bolt pattern in order to use a big block camshaft button, but now, thanks to Matt, I do not have to do that. Here are a few pictures to show how it fits.

Here is the camshaft button from the side.

Here it is from the back side where it fits over the 5/8" bolt head.

This is how it fits on the bolt. It has not been trimmed here.

Finally, after trimming to fit the inside of the cover flush without the timing cover gasket.

Thanks for the tip Rob, Matt’s site is great! In fact just bought some stuff!

For those of you wondering, yes, this was the last piece of the puzzle for me to run the gear drive. I am 100% confident that it will install and work now. So, forward we go. lol

 

[RustyRatRod]

I actually have to trim it a little bit more, because I forgot to include the copper friction washer that installs between the block and cam gear. I'll put that finishing touch on it tomorrow.

That’s a cool setup! You’re going to have to show us a little more of this slant build. I barely even remember there ever having been a gear drive for a slant 6.

Rusty, if you’re using a stamped steel cover I would suggest reinforcing it in the area the cam button bears on. That button is small and will impart a large force on a small area.

Neat , but why so much installed clearance ? Have heard of some guys that supposedly ran .005 on big blocks , I`ve always ran .007-.010....hemi, sbc, 440 wedge .

I may not go that much. Since I forgot the copper washer, now I can trim it for even less clearance. Probably get it down around .010".

The cover is pretty stout right in that area as it has some stamped reinforcements already. Kinda Makes you wonder what Chrysler was thinkin about.

There's not one that I know of.

I use a "Poke it down the middle" (3 bolt cam) version that i made from nylon , on a hemi 6, same style pressed steel cover
never had a problem.
was simpler than chrylser Australias Service bulletin which suggested brazeing a nut to the cover and using a bolt with the end concaved for a steel ball bearing.

Not aware of anyone ever having a cracked or compromised cover due to this mod.
see here.


and here, anceint web site not secure some virus scanners will block you because it is not HTTPS and it has daft geocity web ring adverts. so "1990's"
DR.HEMI Hemi 6 Camshaft End Float Restrait


am aware of people having the chain or sproket carve the front of the cover out, becase they didn't do this mod.

with a gear drive, if the teeth of the gear are true and the cam floats as it should agints lifter/lobe profile and pump or dizzy gear reaction, the button should just work in the same way.

the fluted covers seem to be robust enough
coll product
sensible addition provided it doesn't undo the cam bolt. which is highly unlikley

The 'bolt and stud' setup is a proven method of limiting cam walk on the slant six. However, not everyone has access to welding or the items needed for the ‘bolt and stud’ method. This button is an easier way to accomplish the same thing. With the cam bolt properly tightened, there should be no risk of it coming loose with either method. Cam buttons have been around for many years, this is just one made specifically for the slant six engine.
