914 flywheel vs a bus flywheel, any differences? Options

[malcolm2]

I sure can’t see any.

Building a 2.0 from a 1.8 from a 914 for my 72 bus that came with a 1.7. Have both flywheels. I did not label either. The 914 was running when removed so it must be the shinier one. The bus sat in a field for 10 years. So much moisture under there that the magnesium bell housing deteriorated.

Anyway, both are 210 mm. Some vendors say their 914 FW won’t work on a bus and visa-versa.

Anyone have more details?

OK. That is what I see. With that difference in accessory assembly or attachment, it still appears that the FWs are the same.

If I may ask, does it matter, why the difference? I guess the input shaft is different? More evidence that the rusty one, with no pilot bearing is from the bus.

I have several 914 tranz cores etc...under the house along with my rebuilt 3-rib Bus Tranz. So I will check.
