What Flywheel?

[Rockbronco67]

I have a 1994 Ford Bronco 5.8L. I need a 164 tooth 28oz imbalance flywheel correct? Does anyone have a part number from Autozone or oreillys? I can't find where it says 28oz. and the 18yr old at autozone didn't know what I was talking about. Let me know Thanks


UPDATE: Part number NFW1129 is the correct flywheel

Didn't check the link, but since ALL 351W/5.8 engines were always 28oz, it's a good bet that if it's the correct part number for a 351, it's the correct imbalance.
Only the 5.0/302 went through the change.

That clears it up. Thanks

Just so everyone knows that in 94' they made 2 flywheels for the Bronco. The one in the link actually measures almost 1 1/4" thick. So when you bolt on your Bell housing, it hits your clutch pressure plate. No blame on Jacob because I thought it was correct also. So the correct Part number is NFW1129 from Oreillys, measures 1" thick and works. Just food for thought

Weird... I've never seen one of the thick ones. I wonder if those were only on certain vehicles...

I'm pretty sure that it was a running change implemented in February of 1994 for all F-series and Bronco with the 5.8,

The thick flywheel goes with the larger 11.5 diameter clutch, and it has a doweled pressure plate. Still 164 tooth and 28 oz-in. It's only on the 94.5-96 Bronco. It happened earlier than the ZF update...so it seems like it should fit the bell of the ZF-S42. (not 100% sure...)

The other difference between the early 28 oz 164 tooth flywheel (302 & 351) and the later (351 only) is the spacing of the clutch cover bolt holes. The early flywheel is drilled for the Long Style pressure plate. The later flywheel is evenly spaced. The aftermarket eliminated this problem by putting multiple patterns in their universal replacement.
