So it seems that not many people are running these gears, as I could not find any threads regarding the install of these.

I bought a pair of stock gears since I lost mine during my build, but found on first fire up that the Intake gear was warped. So I bought a set of Brian Crower adjustable cam gears hoping to degree in my cams later down the road as well.

I went to install them and found they have ZERO timing marks. I could lock in the cam position with the stock gears on, then swap over to the BC gears, but there has got to be a better explanation?

Even the vendor picture (now that I look back) shows no timing marks.

What gives? What would you guys suggest as far as timing? I mean, with the dowels at 12, the adjustment marks are way up there at 12 as well?
 
Ya i almost picked up a pair but they had the same problem. I wish they went like this.
 
In the pic you can see timing marks they just point straight up. Not sure how easy it would be to time things that way. I would just transfer over the oem marks off the old gears with some white out and call it a day.

This. Lay the factory gear on top of the aftermarket gear, make sure the dowel pin holes line up, and mark the timing mark with white out or a paint pen.
 
The gears in the picture look like they are for an evo, they have timing marks above at the valve cover.
 
I went with your suggestion and I think It will work just fine. I was just surprised that no timing marks were cut to begin with?

Gus- I also noticed this (the large timing marks inline with the dowel pins), however I double checked and I was shipped the correct part number.

So then, I dug into it more.

It looks like ALL Brian Crower adjustable gears are the same. I ordered part number BC-BC8110, found here (90-99 4g63)

Yet, here they are for an Evo 8-9.. same SKU?? BC-BC8110?

I think greengoblin is runnign these on his build (think i saw em in his build thread), Anyway, the idea with putting oem gears over top sounds perfect and can't belive i didn't think of it before.. I had guessed that they left the marks off in order to force you to properly degree the cams in upon installation
 
On that note, I can't seem to piece together all the proper things to degree them in. I wish someone made a proper shim and solid lifters kit to make it feaseable to degree these engines... I know well enough that a properly degreed cam setup will do wonders. Just never degreed in a 4g63.
 
**** NOTICE ****
If your cam gears are the original 4G63 BC's that don't have timing marks on them to set TDC then they're the old gears with an offset dowel pin hole used on Evo VIII's.

They look like this...

I finally got around to installing my set, doing what was suggested above and just marking them using the OEM gears to line things up, but after I did I had hard starting issues and strange idle problems. All I did was install the cam gears so I pulled everything back apart and compared where the timing gears lined up bolted to the cams with the OE gears and what I found shocked me.


I reinstalled the OE gears and got them to TDC, w/o touching the cams look how far off the BC gears were.

Just for my sanity, I set the cam gears at TDC with the BC gears and installed the OE gears and again...

I immediately emailed Brian Crower with my issue and they emailed me back within seconds with this...
Corey,
Those are the BC EVO 8 gears which have an offset dowel pin location. You must have had these for a while? The new Bc gear has the center dowel for the 4G63 and the offset dowel for the EVO 8.

What is your phone number? Or call me at ext 101.

Thank you,
Dustin Spencer

I called them and he told me to ship them into BC and they'll send me a new revised pair back that have the center dowel that the DSM uses.

These are their revised cam gears that have a dowel pin locator for both the Evo VIII and the 1g/2g DSM.
