Faster 4430 March 03, 2017 07:41AM
Howdy,

I am rebuilding a 1974 4430 power shift with a little over 20,000 hours. I am tearing down completely down and building it back up to good as new. While I'm at it, I would like to speed it up as much as possible. I have heard that 4010 final drives are faster. Is this true? Will they go right in the 4430 housings?

Is there a faster ring and pinion?

How about the "transmisison gear reduction" gears from a 4440?

This tractor will mainly be used for stationary PTO work so strength isn't my biggest concern but I would like to get to a 25 or 30 MPH road speed at 2100 RPM.

Does anyone make a higher geared ring and pinion set? That would be the easiest and possibly cheapest way if a set was available...

4010 finals will work and will speed you up buy about 12%.That will equate to a half gear,probilty about 3or 4 mph.It does require some work though as your rear end housings were you axle housings fit in are slightly smaller than the 4010 housings.You have to take a die grinder and remove enough material for you axle housings to fit,you also have to relocate the spots were your brake plate recesses in you housings.I have done them,takes a couple hours per side.that 3 or 4 mph would be in 8 the gear .

Do I have to use the 4010 axle shafts or will my 4430 shafts work?

4010 axles are 3 1\8 4430 axles are 3 3\8,no the axles them selves are not interchangeable.

So the 4010 axles have to stay with the 4010 planetaries?

You will find that only the very earliest 4430's were 3 - 3/8. JD soon (after a year or so?) made them all 3 - 5/8.

You want to go fast down the road, go buy a JCB. Dairymen around here seem to love those tractors. The powershift tranny is nice & smooth. The big new tractors are hauling triple and quad axle manure tanks. They fly down the road, even when loaded.

4430 never came with 3 5\8 axles ,they came on 4630 and 6030.All 4430 and 4240 and 4055 all had 3 3\8 axles.Besides has nothing to do with the guestion.

There were some 4430s with long axles that had 3 5/8 axles.Doesnt make sense as first 4440 had 3 3/8 but I buy and sell several tractors plus duals and hubs and have personally seen some. .Going to step up 42 rims and also increasing RPMs would get you there.

Actually it wouldn't. 4010 final drives (12% faster) and 18.4R46 tires (13% faster) will only get me to 23 MPH. Couple that with 2500 RPM and we are at 27 MPH.

42's and 2500 RPM would barely be 23 MPH.
