Yea, that is the upper timing gear for the camshaft. It's aluminum and a (2) peice design (the 4 bolts hold them together)... it's adjustable every .5* . Actually there are a fair amount of little parts to that Comp Cams belt drive. That cam gear bolts to a tapered and keyed mandrel with a single left hand thread bolt (center)that mandrel bolts to the front of the camshaft (with 3 allen cap screws) and a thrust washer set encased in a stainless steel housing that bolts to the front of the cover behind the gear. You have to juggle bronze shims around inside the housing to get the camshaft end play in spec. There is also an oil seal in that housing for the mandrel to go thru. We did have to modify the cover assy a little.... grind on the backside and the block for clearance.... then just drill out the dowl pin holes a little so that you can center the entire assy by the 2 oil seals - Then bolt it up to the block tight.... otherwise you run the risk of having the seals leak because the cover is not in perfect alginment with the camshaft and crankshaft. This is a common mod and the way everybody makes sure belt drives don't leak. This is what it looks like with the upper timing gear and belt removed.
