Where to Buy: Steel Flywheel for JD 4430 March 01, 2023 12:28PM
I’m looking for a steel flywheel for a John Deere 4430. I am sticking with a wet clutch right now behind the factory 404. I foresee a 466 swap in the future so I’d like to get a steel flywheel that is set up for the 466. The way I understand is I can use it on the 404 and swap it to the 466 (add two bolts) when the time comes.

I’ve called:
Kenny’s Pulling Parts (left a message with no returned call)
Kentucky Clutch (answered phone and supposed to be getting back to me)
Atlas (I plan to call them this week)

Any other places I should call to find a flywheel?

Rursch.
I don't know why a person would call anyone else.

We run a Rursch wet clutch. I don't know what class you run but we put a billet input shaft in ours. We learned the hard way.

I have a 4 disk atlas Wet Clutch that will be coming out in the next few weeks and will be for sale. 1/4" floaters that could be exhanged for thinner floaters to allow a additional disk(5th disk) Latest and Greatest from Karl and he was great for support. I am only removing as we have began to out run the clutch's capabilities. 6zero8-7three2-zero6five3

How much power do you think you’re making? Did the quad range give you any fits ? Was your input shaft stock ?

I have seen this subject before, wet clutches for too much HP, what does it take to change over to dry clutch.How big of changes do I need, new brakes, different housing, thanks.

A guy we pull with mated the front of a 4440 with a 4320 rear. Big job. We are at the iffy stage on HP for the wet clutch according to Rursch . I'm not sure what route we will take once we go over that hump. Maybe put our motor in a dry clutch chassis.

I running an Urmson 4 speed (No quad) so i cannot speak on my own tractor. Also never been on a Dyno

A fellow tractor was running wet clutch/ Built 4430 quad(Direct and under)/original 4440 trans for some time running before having issues at that 1000+/- area.

Just an update. I really appreciate the info and offers from everyone. I spoke to Rursch last week and called back today and placed my order. The gentleman on the phone was very good to deal with.

Thanks for the update. I'm glad to hear they were good to work with. I'm sure we'll need some parts from them someday. Just for info. we run a 5 disk at 210psi. We have a gauge right by our shift lever. On ours building boost and letting her go is a little tricky with the wet clutch.
Have fun and good luck.

Appreciate the info. This is a new to me tractor and is bone stock. I plan to work over the 404 a little for this year and if all goes well I will swap a 466 in for next year. In the name of safety I wanted a steel flywheel installed so I won’t have to worry about rpm and it will be a good base for the future.
