Well - thought I had this nearly buttoned up and thought the whining was from a too tight primary belt - but sounds like the whine is from the Andrews cam gear - guess I can either press off the Andrews gear and press on my original or screw around with the pinion or Andrewsd - Andrews claims to have a smaller gear size but they fight with me when I call and try to blame Harley for making too many pinion sizes.

Has anyone re-fit a cam gear? I recall the Andrews fella telling me not to heat anything - it's a cold press - and he said not to apply pressure to the face of the shaft as I recall - but how do I index the dam thing??????

 

Back in the 90's Andrews did a lot of pressing of cam gears for me Just sent them their cam and orig engine cam with gear no problem Maybe times have changed at Andrews ?

 

go ask at the evo section about the cam gear and someone will post up pictures and a explain how to -- its done all the time no biggy

 

I just talked to Gary at Andrews - they don;t do the "service" for you - and they don;t exchange gears anymore - I can buy a .002 under gear - press myself - or just press on my old gear - as an ironhead guy - I lap gears - so I'm unsure if the old gear is still viable to press on or if I need a new gear - will the old gear be loose??? Andrews will sell undersized cams but you have pre-order from them

Gary indicated that heating to about 250 is okay but be careful not to anneal the gear - term for taking the hardening out - I have a 20 ton press and a large industrial oven in my shop - just a bit concerned about the indexing of the gear to the shaft for timing - but a little advance on the cam timing would benefit the low end anyway - so I may just try and get it done tonight - in Minnesota - we'll run out of riding time pretty quickly once we hit Fall - and I want to rid the bike

 

Are you sure you have the correct cam gear for your engines gear set ? 77 was the break year early cams were bare, the later with a different tooth profile had a groove on the face of the gear. Later gear on an early pinion set would howl and eventually grind themselves up.

 

the H cam that came out was an early style - so that's what I bought - just pressed the gear on and ran it to check runout on my lathe and the gear is not true - WTF - getting about sick of this - should I press it off again? You can see the lathe tool mark is not even in the photo

 

.. and you're getting run out on only the gear? The cam is running true ( 0° ) ? Dumb question, did you check it with a dial indicator?

 

that cam is a taiwan tedd cam - V Twin made in india its is not even worth its weight in metal - the 8 /32 thread is coming apart in the end of the gear as we speak - and the first lobe against the gear is pitted - dont use that one

you need a groove gear for the andrews cam you have as you have a late motor as twisted rightfully said

 

Have to agree with John that does not look like a stock H cam the metals too bright and like he said the small threads are hashed and I've yet to see a stock one do that. Snap a pic of the needle bearing end of it and post , we'll get you sorted out.

 

It is an Andrews cam - pretty sure the gear is the original Harley gear that I pressed onto the Andrews cam - and yes - I'll throw the dial indicator on it - on the lathe - it's only about a thousands off - but hearing Jon's comments I wonder if the Andrews cam is **** as well
