    6.5 should use the same flywheel as the 6.2. A manual tranny was offered behind the 6.5TD...the NV4500. The donor 6.2 I bought already had the flywheel, pressure plate and clutch disc bolted to it when I got it, so I can't help much with pn#'s.

    You might want to check the diesel part number thread, I think it might be in there.

    The diesel uses a pilot bearing, which some people don't like. I replaced the messed up one on my 6.2 with another bearing (rather than a bushing) and haven't had any trouble with it.

    I have seen 6.2 flywheels on eBay a few times too.

    No, they came backed by a nv4500. The way i look at it though, if a 6.5 NV4500 can be put behind a 6.2, then there should be no reason that a 6.2 SM465 cant be put behind a 6.5. I would think that the NV4500 flywheel would work fine. Dont quote me on it, though, this is just an assumption, but it makes sense to me.

    I would just use the 6.2L flywheel, it is solid Vs the 6.5 dual mass style. I removed a dual mass and installed an older style into a NV4500 equipped truck. You just need to make sure to get the proper clutch for whichever flywheel you go with.

    I agree with Diesel Dan. Don't use the 6.5L dual mass flywheel, they're known for being trouble when they wear out and come apart. Just use a stock 6.2L flywheel for the SM465. It will bolt to the 6.5L just fine.

    The 6.2L and 6.5L are, in nearly all respects, identical blocks on the outside. A 6.2L will replace a 6.5L, and vice versa. Most of the differences are internal. Therefore, a 465 doesn't know if it's behind a 6.2L or a 6.5L.
