Steel timing gear bronze spacer. 140-160 1974

I finally found the steel timing gear for my b20. Is the bronze spacer the same as used for the fiber gear? What do gurus use for shims?

Sorry I can not help your with your question, but you did a T-5 tranny swap? Can you tell me what spider was used to mate the Ford output shaft to the Vovo driveshaft? Or what did they do to hook them up. My dirve shaft shop is not sure if they could find a spider that would work. I have a T-5 fron a 87 turbo t-bird.
Thanks

I used that exact tranny. Code 155. I just cut to balancer ring off the outside of the Ford yoke to make it smaller to fit in the tunnel. Replace the tranny output seal, some say replace the yoke bushing while the tranny is out, also.

My driveshaft shop had no trouble doing it.

I'm certainly no guru, but I'll toss in a couple of penny's worth!

The terminology I use:
Spacer - the little ring that fits over the cam and is bolted in between the cam and the gear. The gear is slid down onto the cam nose until it locks against this spacer.
Thrust plate - the plate that also sits between the cam gear and cam, but has two bolt holes and bolts to the block. Its job is to control fore and aft movements of the camshaft (introduced via variations in the torque loading acting on the angled teeth)

But the spacer isn't specific to the gear - it and the thrust plate are a pair. The gear (steel, aluminum, or fiber) slides down the cam nose as the nut is tightened until it positively hits the spacer, thus leaving a specific gap between the front of that big bearing on the cam and the back of the gear. That gap needs to be just a tiny bit wider than the thickness of the thrust plate. If the spacer is thinner than the plate - the plate will be pinched between the gear and the cam bearing and be very stiff, and likely cause big problems if run that way. If the spacer is too thick the gap will be too large. This will lead to a clunking noice at idle and (eventually) a premature wear-out of the thrust bearing.

What do you mean by 'shims'? Maybe I'm missing some basic part here - but I just put together my engine and (as with the many times I've swapped cams or rebuilt engines before) there were no shims involved with the cam.

I guess I'm referring to the spacer as the shim. Do these spacers come in various thicknesses to accomodate variances in thrustplate\gearface clearance?
I'm doing this from memory. I haven't actualy looked at the engine in awhile.

Any other issues with using steel gears; position of oiler, technique for testing oiler position?

Thanks.

Remove the oiler and clean thoroughly with carb cleaner. You'll be able to see cleaner squirt out the pinhole and know it's open.

It goes so the outboard edge -- the one with the short overhang relative to the tube -- is parallel to the edge of the timing cover. The long overhang side points in the 3:30 - 4:00 position. That aims the pinhole right at the junction of the gears. It's not super critical.

No, both the ring (spacer) and the plate are standard thickness and do not
come in oversize or undersize. The ring is pretty much bulletproof but the
plate gets worn and should be replaced.
