E: Engine Cam Suppliers

[Robert Watson]

So it has probably been thrashed a hundred times but if a guy wanted and new good cam and followers (Mk2 for a Comet) where would he go here in N America. Megacycle? from whom? What's the experience with Maughn ones?

thanks

What? Your own parts shelves getting bare?

 

[Vincent Brake]

Britt parts.
Thats where EU boiis gets them.

Megacycle that is.
Check the play at the pinion side

And one could drill a hole in the base circle for oil on the followers.

Cheers

Neal Videan has new cams in Mk 1 and Mk 2 profiles, and half the price of the Uk supplied ones.

 

[Martyn Goodwin]

Neal has cam followers as well

And a few other bits n pieces

I like Megacycle. The quality is very high. Ask for the Oilite bushings, otherwise they will install phosphor bronze. They make Mk1 and Mk2.

Megacycle will reface and harden followers (or they use to), but new followers are much cheaper. I get them from Coventry. They are quite good. I try to test them for hardness and they run about 60 which is what I am looking for.

The engine I built for David Tompkin's racer is running this setup currently. Jim and Barbara own the company. Barbara answers the phone unless daughter Lisa does.

Better than no hole at all.
Do you run your cams with the oil hole in the base circle?
And to drill the hole? EDM?

 

[Vincent Brake]

Yep on the base circle.
Not where MC does have the holes.
We just lack the pressure. To press it when the follower hits the cam.

EMC or with diamond hollow drill 2 mm.

I also timed the spindle in the casing.
As again we do not have enough oil.

Cheers

The timing of the hole in the cam lobe verses the hole in the spindle is an example of some of the design failures within the timing chest. I put the cams in the lathe and machine an internal radial groove that aligns the hole in the spindle with the hole in the cam lobe, and sometimes this groove is wider to allow this. Carrying out this simple mod will allow oil to flow continuously no matter the position of the cam and hopefully keep the survival rate of the lobe and follower a bit better.
