Hi Juan,

To find a Long Stroke camshaft in good condition is difficult today (because LS have eaten it for lack of oil). Perhaps here:
 https://www.draganfly.co.uk/index.php/component/hikashop/product/14693-camshaft/category_pathway-2?Itemid=505
(You will find lot of information about A7 parts on this site)!

 If you have access to a good engine reconditioner or workshop, you can use a better available A65 camshaft, but then you have to grind the shafts down!

Regards Rudolf

I was very lucky as the cam in My longstroke "Star Twin" is nigh on perfect ..I am putting together another bottom end & am considering investing in having My spare camshaft reground /hardened , etc ?

I have been advised by a forum member that Newman Cams are very good ?

Wonder if any forum member has any experience in this procedure & this firm please ?

Perhaps if no other option is available to the gentleman in Aregentina this may be a possible solution ?

Rudolph,
                    Have you actually fitted an A65 camshaft? Or know of anyone doing it?
Years ago I looked at doing this but it wasn't worth the effort as I had good cams.
Will the lobes run with the A7 followers or are they too high?

Trev.

Hi Trev,

the camshaft I actually using in my LS is still in specs. But it is the last good one I have and hopefully it will last a while (in the meantime I fitted the second oilfeed to the inlet valves).

But shit can happen so I looked for a A65 cam. As I can measure the lobes and the timing is quite similar to the LS camshaft.  My local workshop friend can do the grinding for little money- so I hope.

Cheers Rudolf

Steve ..

Newman Cams are very good, perhaps it was me who told you. Have been away for a while!
They made two new longstroke camshafts (nitrided) for me several years ago from an original I supplied, so they have the profile and should be able to make for anyone requiring one.

[Stephen Foster]

Thanks "Rusty Nuts" , could well have been Yourself .

I intend to ring Newman Cams later Today .

Steve ..

[terryk]

Steve let us know if Newman Cams can make new long stroke cams I would be interested in buying a few.

[Stephen Foster]

Terry ,
I will ring next week now & let the forum know the details , etc .

Resurrecting this topic as in need of a new cam shaft for my LS

Rusty Nuts - you mention that Newman Cams have made a new camshaft for you. I spoke to Ken today and he asked me to send my existing shaft over to him top "copy" as such. That is not possible for me

Any chance you could share with me more information on your order with Newman Cams, like invoice number etc that he could look it up?
He could not off the top of his head recall making one, so hoping to provide him with more detail and that way he will be able to produce one without a sample.

Appreciate the help.

Hi Craig, I used Newman Cams to make a new 67-695 camshaft for my long stroke A7 in September 2010 and was really impressed with the quality. They also hardened the NOS cam followers I had to match the hardness of the new cam. I spoke to David who knew what I wanted when I quoted the camshaft part number. Cheers, John

[Craig]

John - thanks for that additional info.

Just called Newman cams and they advise they have 2 sets of records. High lift and low lift cam profiles.
Any idea which one is correct?

[fastharry]

Be careful of the high lift. i was given a cam from them, and had to send it back as the lobe hit the casing when turned,

[Craig]

Thanks fastharry

I was lucky enough to find an old camshaft for sale in Holland (of all places).
Newman cams have just re-done it for me and also a NOS set of cam followers.

But i will heed your advice and check clearance when installing it.

[vinver]

Craig, mind if I ask what Newman did to re-do  yours ? And what was the cost if you don't mind me asking? Thanks.
