That tractor depending on serial number would have a straight pin with 2 spiders or the later ones have 3 spiders and either one should have needles inside the spiders from the factory.

The quad has 34 teeth on the countershaft in D range where a syncro has 36 teeth in the same location. so the quad has a ratio of 23.2:1 in D4 and the syncro has a ratio of 21.9:1 in 8th gear. This is the ratio from the engine to the axle though, not to the ring gear. You also have to account for the planetaries.

Most use crower lifters that were made for big block chevys. The block must be bored to accept these larger lifters and keywayed.

Most tractors that I have seen use these pumps on a wet sump system. Tractors have plenty of room for a deep pan to get the oil away from the crank so a dry sump system is really unnecessary. We put one on a John Deere 466 motor and it has 2 stages pumping oil from the pan to the motor and another stage to pump fuel to the injection pump. If you wanted seperate oil for the turbo you would need a

Those transmissions have 3 speeds from the countershaft to the pinion shaft and then they have a high and a low range in each of those three gears giving you a total of six gears. This is what I did to an 1800. I made a new 1st & 3rd gear, a new 2nd & 5th gear and a new low range gear which was actually faster than the original high range gear. So it ended up having the original speed in 6th gea

If you put hydraulic oil in the master cylinder, that is probably your problem. I am not sure how long it will take but the oil makes the cup in the master cylinder swell up. So when you let off the pedal, the swelled cup is still blocking off the hole where more fluid should be drawn down into the bore of the master cylinder. Orings are available from mcmaster-carr.

How big of piston does your master cylinder have? if it is too small, it will not have enough volume to move all three brake pistons before the master cylinder runs out of stroke. We used 1" pistons and it works well.

The male splines on my top shaft are 1 3/4" - 27 . That is the biggest shaft that will fit through the front bearing that I use. What size is the shaft that goes into the quad?

I am not very familiar with the quads. I don't have a way of putting in the internal splines like the stock top shaft. I don't think you would even want to because this is a weak spot in the stock setup.
Can the stock shaft coming out of the quad be removed? If it can I may be able to make the top shaft go right into the back of the quad.

A 4020 stock 8th is 22.04 : 1. One tooth larger on the counter and one tooth smaller on the pinion would be 20.62 : 1 which is roughly 6% faster.

I don't know much about the 3010 but a 4010 rearend housing is lighter than a 4020 and if you get the early 4010 axle housings, they are lighter than the later 4010 axle housings. The 4010 has shorter shafts and smaller bearings in the transmission making it a little lighter also(not much). The 4010 will have 6 teeth on the pinion making it a little weaker and slower than the 4020 which has

I would also recommend leaving the original internal brakes and mounting master cylinders. The external brakes will not save that much weight and leaving the stock internal ones will save a lot of money. You should pull out all the brake pistons and install new orings compatible with brake fluid. Make sure to blow out all the oil passages because if any oil is left in the system it could make its

If anybody needs one, I have a rear differential and ring and pinion from a 7520 that I would sell cheap. I bought it on ebay to needle bearing and I was going to resell it. The JD website listed the differential as being the same as a 4020 but what I didn't realize at the time was that the front differential is the same as a 4020 not the back. LOL

There have been alot of guys run IH rods on a John Deere. I don't remember exactly how much narrower the IH rods are but somewhere around 1/4" maybe only 1/8" and it doesn't seem to be a problem. I am not saying it is ideal but it works.

C4 with 4010 planetaries would be a ratio of 30.9:1. Sorry I do not know the ratio of the 4440 2 speed. If anyone knows the ratio of the 2 speed overdrive I could figure the ratio for you.

I will be the first to admit that I am not very familiar with the quads. I believe that the quads are basically a 2 speed mounted in front of a syncro range. So c4 would be when the 2 speed is in high and I think this is direct in the 4430. So it would basically be like being in 7th gear of a syncrorange. The gears inside the transmission of a 4430 have alittle different tooth counts than say a

We make 3 speeds for small block Deeres and we have also made some new gears to go in place of 8th and 5th gear and still use your old shafts if you don't want a whole speed.

A 4010 has the following tooth count in 7th gear
high range pinion to counter=23 driving 28
Counter to pinion shaft 28 driving 33
ring and pinion= 6 driving 37
planetary =18 driving 57 formula for planetary ratio is 57/18 +1=4.167
All driven gears multiplied together and divided by all drive gears x planetary ratio
28 x 33 x 37 / 23 / 28 / 6 x 4.167 =36.868:1
pretty close to 36

When you say your crank is bad, what is actually wrong with it? If it is just the rod journals, they will weld these up when they stroke it so that really won't be an issue. Now if you have a crack or something like that then that is a different story.
If you want something fairly cheap, you can use cat 3306 pistons, 4 3/4" liners, ih 466 rods and stroke the crank 3/4" and you will have a

I am the one that did the maching on the one that is for sale on the for sale page. You can pretty much see in the pictures what needs done. You will need 2 sets of the pto gears. This works for a cheap setup but most all the ones that I did eventually go to a full three speed with new shafts.
