The Stovebolt Site Forums The Shop Area Driveline 11" 6 bolt Flywheel

Hello, does anyone know if Sachs or another company makes a new Flywheel that will accept a 6 bolt 11" clutch to be placed Aon a 45 235 or 216? Thanks

I just removed one from a 261 which also would fit the 216 or 235. so yes they are available. Dave

I know know original ones can be found, but is anyone making new one such as Sachs and is there a part number?

Here is an example of the problem; Rockauto says this flywheel is for a 56 261, however the center mounting holes don't look correct to me.

Lend-Lease, sometimes the pictures that Rock Auto shows, does not match the description. So it very well be the right part.

Call their tech line and ask them to measure one. I think I'd trust a direct conversation with a vendor over somebody's SWAG on an internet forum.

I've looked at more than several examples of the Sachs part nfw1007 and it obviously won't work. The problem lies with the three dowl pins that line up the flywheel correctly on the crank. As you know one is a bit off center between the mounting holes and none of the new products are made that way. Did some cranks only have one pin on the crank?

Those dowels are there to align the timing mark with the #1 and #6 cylinder top dead center. As long as the bolt holes align, a flywheel could be installed without dowels at all as long as the bolts are a tight fit in the flywheel holes, or just one dowel could be used if you're willing to re-mark TDC on the flywheel. Be sure to plug the unused dowel holes to prevent possible oil leaks. I'm not sure if the dowel holes go all the way through to the crankcase- - - -but I'm sure the bolt holes do. I lost a clutch from oil contamination shortly after purchasing a 59 3800 with a "rebuilt" 235 because the PO left a flywheel bolt out after cross-threading it.

Thanks Hotrod. I actually found a very nice original to use, but I greatly appreciate the help. I am baffled by the lack of newer flywheels being made for the 216-261, you'd think even a limited run would sellout without difficulty. I've changed my 46 1.5 to an 11" clutch for the ease of replacing the clutch if needed, now the 45 is next. thanks again

For a while McLeod was advertising 235/261 steel flywheels. I figured they would know what they were advertising given they were jack Clifford’s source for steel flywheels (I have one I bought back in 83 or 84). Ya, right. It was the single dowel late model flywheel. When I called tech, they could not answer the question. I got a call back from one of their old school guys who explained that they did not in fact have new flywheels, although they did still have the blueprints to make them up. Cost, pretty steep at like $500.

Sorry for the late response Dragsix, but GOOD LORD, that's ridiculous.
