Dowel pins don't fit new flywheel

merc123 · Nov 30, 2010

Just got a new flywheel and the dowel pins out of the OEM flywheel will not fit the new one. It's an O'reilly (Sachs Part Number: NFW1175 ) flywheel and the holes are too big for the pins. Am I missing something?

Why didn't you just have your stock flywheel resurfaced ? I'm sure it would have been much cheaper.....

The new flywheel didn't come with dowel pins?

Normally a "dead blow" hammer is needed to remove/install the dowel pins. The fit should be tight.

Might be helpful to go back to the store and ask.

The old one was bad off from bad clutch/pressure plate engagement. Mechanic strongly recommended not resurfacing it. Had a lot of hot spots. The flywheel was only $60. It did not come with pins and I called the manufacturer and they confirmed it as well that they do not provide them. The holes in the flywheel are about 5/16" and the dowels are 1/4" or so. I asked O'reilly's and they didn't know so they ordered a new one. Going to see if the holes match in size tomorrow. If they do then I'm not sure what I'm going to do.

You can always try to get a used one from a junkyard and resurface. If nothing else the people that make the flywheel should sell dowels. If they don't that is a total joke. Ebay is a good option to get an almost new flywheel that someone pulled.

Company doesn't sell them at all. They said go to a machine shop that surfaces flywheels and they have them.

After many hours on the phone with 100's of people we finally got it figured out. It is listed as a flywheel for a 4.6L but it is actually for a 3.8L. Apparently the 4.6L flywheel is a dealer only item unless you go to JEGS or somewhere like that...

Update: New dowel pins from Ford... They are different sized now.

You need to get metric dowel pins: Jegs P/N 397-M-6397-A302

Ford I think is just M-6397-A302. The dowel pins came in a pack of 6 so I had to buy the entire pack from Ford.

I was going to say it sounds like the wrong clutch. Pick one up from Summit.

Clutch was fine, it was the flywheel.

I just bought an open box SPEC flywheel. How many dowel pins should I have received? Looks like I got 3...

Three is the number of the count and the number to be counted to shall be three.

i think thats a yes.

You didn't like my cryptic Monty Python-esque way of saying yes ? =P
