Xflow timing peg
joneh - 2/3/19 at 02:28 PM

Hi,

Just rebuilding a xflow with a Newman's PH3 cam. It didn't come with a timing peg/dowel. As I'm using standard timings, do you need to fit one? Don't the bolts hold it in place?

Thanks
Jon

Forget that. I see the bolt holes are bigger to allow offset dowels.

Every day is a school day!

Probably better to time the cam properly rather than using the standard marks

Yeah been thinking about this. Should I time it properly first then just order the right dowel? I'm using the standard timing gear.

Newman state standard time marks are fine but it can't hurt to double check and adjust...

Time it up using a DTI and timing disc then order the correct pin, Burtons website shows how if you have any doubts . Must admit I used a vernier gear when I rebuilt mine but I fitted duplex gears and chain

Depending how much bang there is in the cam you can quite easily get away with a simplex vernier timing wheel. However, as stated in previous post, you must use a dial indicator and DTI. If you go the peg route buy a set from your local supplier and save a lot of wasted time......

You've gone this far so may as well time it. From memory you you reference positions turning the engine one way to eliminate backslash.

All you need is a dial gauge and timing disk. Google engine timing disc pdf.

Yup going to time it correctly, then hopefully just order the correct dowel.
