Flywheel assembly

[46u]

I know in 2003 they went from the dual Timken cone bearings to the ball bearing on the power take off side which in my opinion was a BIG mistake. Any how are all the flywheel assemblies the same? Well the 2003 and later fit the 1999 to 2002 twin cam cases? If so what is the part number for the 96 and 103 flywheel assembly? I want to make mine a 96. Not so much interested in speed just want to increase the fuel mileage.
Thanks

Any one????

[Mtclassic]

you can not use an 07 (06 dyna) and up crank in a earlier bike to make a 96".

May I ask what the difference is between the 06 dyan and the 07 and later flywheel assemble is other then stroke then from the 03 and up?

Comp side spline are different and not intercangeable.
You said you want fuel mileage, what are you getting now?

So you could get a later compensating sprocket set up and make it work? Right now mine is bones stock depending on my speed I get from 38 to 41 MPG with my stock 02 Ultra. The first thing I am going to do besides put the screamin eagle hydraulic cam chain tensor set up in mine is a 6 speed.
THANKS

No the cases are different but if you want to spend enough money anything will work. bottom line is the 02 crank is miles better than the 96 crank as far as durability goes. If you want to stroke yours get a SE 103 crank or S&S crank with the timkin set up.

Screamin eagle has a kit Jim's makes it for HD to change the 03 and later cases to twin timken bearings like the earlier models using the 1971 and later bearing. I do not want a 103 I want a 96. Big bearings started in 1955 but the style timken used changed I think in 1970 or 1971. Either either way first or second year of the cone shovel. YES I know the 03 and later cases are different as they run the ball bearing.

Give you a little back ground on my self. I have been riding and working on Harley s none stop for 35 plus years. I can take the EVO, shovel, Pan and totally build the crank at my house including but not limited to rebuild the rods, assemble & true and line bore the cases. I have a small machine shop at the house and use to have a shop for 13 years. To this point the latest model Harley I have worked on is a 05 so I am not well versed on the later ones. Below are a few pictures I took for insurance purposes. The old Western lift in the pictures all beat up I bought new. I do appreciate all input but I am FAR from new to Harley s just learning more about the newer ones. The old 1988 FLS in the pictures I have been working on since new which now has over 200,000 miles on it. This is only part of what I have for working on Harley s.Thanks

Here is my lath but I need to get off my lazy butt and set it up. LOL Have not had it set up since I closed my shop in 1998. Closed it do to not being able to find good reliable help and raising 3 girls as a single parent. Thanks.

The only thing that makes the 02 and earlier better is the dual cone Timken bearing set up. If you run a S&S kit with out this set up they will not warranty there parts.

The cranks 04 and earlier are forged the cranks 05 and later are cast. It is much more common for 05 and up cranks to be out of true. 07 and up even more so.
If your heart is set on a 96" you can call AMS and his big bore cylinders are 96" vs 95". I have an 04 95" mild head work etc. I would be more willing to go bigger if I had timkin bearings but do not want to split the cases at this time to do it. I ride with plenty of 96's and they do not get any better mpg than I do and some get worse. If you have boring equiment you can bore your stock cylinders to 96" with no problem. some go to 98"

Thanks for the information as I did not know this. Interesting that your 95 gets as good or better gas mileage then the long storke 96. Years ago I had a storked shovel head I built with stock bore. A few years later I put the 3 5/8 bore and gas mileage went way down. Matter of fact when it was just storked it go better mileage then a stock 74 even with the big S&S carb on it if I keep my wrist out of it.

You would think with a longer stroke you would go father on one revolution then with a shorter stroke If all the gearing and such was the same.

Thanks I new the 95 inch cylinders are nothing but bored out 88 cylinders. I have a couple spare sets of cylinders and might bore out a set. I would prefer to run the Harley pistons with the Teflon or what ever on them. Does the Harley 95 piston have the Teflon?

I talked to two different certified Harley mechanics today and they thought you could interchange flywheel assembles by taking the spacer off the the motor sprocket shaft.

Thanks for the information. I really need to up date my manuals as all I have now is 2005 and earlier.

[Mtclassic]

yes the SE flat top 95" have the teflon coating. have your certified techs quote you a price for doing the conversion and then make them sign a contract holding them to it LOL>. Looks like you have a nice set up.

Does any one know if the SCREAMIN' EAGLE PRO STROKER FLYWHEEl AND ROD ASSEMBLY is cast or forged? All so according to the listing fits 99-06 touring so my original question seems to be that you can run a none timken bearing (roller bearing) fly wheel assemble in a 02 and earlier. I guess it does not cover later models do to the motor sprocket shaft splines.This is what it says on Surdyke Harley Davidson web site and I quote. What do others think????

[SCREAMIN' EAGLE PRO STROKER FLYWHEEl AND ROD ASSEMBLY
This 4-3/8" stroker flywheel assembly can be combined with 3-7/8" cylinders and pistons to produce 1690cc (103") displacement. 4.00" cylinders and pistons for 1800cc (110") or with 4.060" cylinders and pistons for 1856cc (113") displacement. All EFI models require ECM calibration (priced separately). For race application only. Fits '99-'06 Touring and '99-'05 Dyna® models]

Yes I do have a boring bar. Old and slow like me but cuts very well. LOL
