Hey guys, So this is kinda a loaded question. I have a hydraulic roller cam from comp ground on a billet core. I also received a bronze drive gear as well. I have my old oil pump driveshaft, and I noticed that the new gear from comp has a hole for a pin. How do I go about getting this new gear on the old shaft? Does the old gear press off? Also, does anyone know what size pin I need to hold the new gear on? My second question is this- I did a quick search a found alot of guys asking about the longevity of these gears, which has me worried  This is a street car that sees upwards of 3000 miles a year, and I don't want that gear getting all chewed up. Im going to be running Brad Penn grade 1 10W40 oil in it, but other than that, what can I do to help this thing live? Or is not even something I should be concerned about? Thanks! Matthew

Yes they press off... I dont remember the pin size... being that your running hyd roller you dont have the big spring pressures that the solids do... with the big pressures the cam tends to snap over which hits the gears pretty hard causing the wear so I dont think you'll have a problem

Thanks for the info Mr. P! Anyone else know the pin size off hand? Anyone want to share street mile experience using these things?

I believe the pin size is either 1/8 or 3/16 I can't remember. I had some cold rolled steel rod at the house that I used for a pin and just peened the ends over a little.

Just changed out my gear only and had Pettis press it on the MP shaft using just a roll pin which everyone feels should work fine being it`s a solid press fit. I suggest the rollerized torrington mod where you mill the .140 difference of the bottom of the gear then the wear bet. the bushing and gears on the bottom is nill and the gear mesh pattern will be more consistant. My bushing was wore over .040 and now my timing barely varies 1 degree...............well worth it. 
so this mod that you speak of is simply machining a certain amount of material off the bottom of the gear?

Thanks for that info man!
Would also like to hear some opinions of how well these things hold up to LOTS of street driving?

I have never changed a dist drive gear. The original gear does NOT have a pin in it. So would I have to drill out the shaft to install a pin?

I believe the hardened tip drives have a pin, stock ones do not. There may be exceptions though. These things are tight on that shaft, so I don't know if pinning it is really necessary but I doubt you could drill it anyway it would need to be machined.

Buy the MP one and get the bronze gear from Comp Cams and change it. You'll be about $100 in to it.

That I can't answer, I gave up driving my cars on the street about 20 years ago after some Q tip plowed me from behind.

Any lock collar that you can find to keep the gear from climbing up the cam. The collar goes on the distributor. I have a kit from hughes, and they come with detailed instructions. I reused the bronze gear out of my 360 build, It had barely 1000 miles on it by the time my 408 was done. It looked new.
But it wasnt a solid roller it was a hydro roller. Now I have a solid roller with typical solid roller spring pressure on it. I did everything I could to keep the shaft alive. New bushing, collar on the distributor, and used a LOT of molley on the gear prior to fireing it up.
I also used glyptal inside the engine to allow better oil drain back back by the distributor gear. I have seen crud, and chunks of crap back there causing oil not to get into the bushing, so I basically built up the step where the bushing goes into the block with some engine epoxy so the draining back oil can get in to the bushing and not get channeled around it.
Over kill, maybee, but I am not out anything.
If I knew of the milling idea and torrington bearing I would have done that too.
I highly recomend the collar deal your Timing will be ROCK steady. Also a very good timing set helps too.

Thanks for the advice Kasey!
I just checked the Hughes website and can't seem to find this collar you are mentioning? Those are some other really good tips you mentioned as well.
This cam is also a hydraulic roller, not a solid, so hopefully that will help? lol
About the Torrington bearing mod, Thumper, do you have a picture of it? Im not quite able to picture it, unless I am just reading your first posts description wrong?
