3 Point bushings

[markh1]

As you are sitting on the tractor my left 3 point arm is leaking. I have the arm off and also the back. Does anyone know how to get the bushings in and out?
I have a 3 point lift kit to put in does anybody have that process documented

There are set screws in the lift shaft bushings,on the top of the housing,do you have them out ?the upper sub arms off ?and the seals out ?

I have the 3 point arms off. I didn't know about the set screw but I will look when I get home. I haven't taken out the seals I wanted to find out how to remove the bushings before I started.

Thanks,
Mark

When I took the seat off to get to the set screws 1 of them was loose. I tightened it and the shaft didn't have any play then. Going to put fluid in to see if it leaks before replacing the bushing and oil seal.

Make sure the little air breather pipe in the fill plug isn't stopped up. That can make oil come out the set screws.

Hey Mark,

any news on this issue?
i have the same problem and i am pleased to know if your leak and slack stops after you tighten up the set screw.

Best Regards

My set screws leaked and would work loose so I took them out and wrapped them with Teflon tape like it was a plumbing fitting. Put them back in and they now stay put and do not leak.

When I put fluid back in the tractor it was leaking. I drained it and when I took the back cover off the bushing was loose. The photo shows the bushing was bad. I replaced the bushing, oil leaf and oil seal. Filled it back up with hydraulic oil and it sat for 2 days and didn't leak. When mowing I was using the 3 point and the next day still no leak. The next time I mowed the next morning there was hydraulic oil on the floor and it was leaking a lot. I don't know if the outer side of the seal is to keep debri out or to help keep the oil in. The seal that was in there originially was a 60 42 8 and the seal I replaced it with is a 60 42 10. You can see the difference in the oil seals in the 2 pictures. The outer lip of the 60 42 10 seal doesn't cover the splines on the shaft but I don't know if that would cause a problem. I used locktite on the set screws.

That's curious. My book shows the seal to be 42x62x10

[markh1]

My mistake measurements are 42x62x8 and 42x62x10. My book says 42x62x10.

How high is the oil level in you tank? The reason I ask is according to my dipstick the oil is just to about the bottom of the seal/bushing area when filled to the proper level.

I just wonder if you are overfilling it?

Chris

 

[markh1]

The level in my tank is correct according to the dipstick.

The level in my tank is correct according to the dipstick.

With some folks, that's a matter subject to interpretation. On mine there's one mark, ~1/4" from the bottom of the stick. I consider that the full mark. Any higher, and there's a mess down the backside of the tractor. And in your case, I can see where it might come out laterally as well.

If there's any fluid on the stick at all, I consider it full. I never add a drop till the stick comes out dry, then only fill it back up to that bottom line.

From the bottom of the dipstick to the bottom of the 'cap' with the vent holes in it measures 3 1/8" long and the mark is 3/4" from the bottom of the dipstick. I've had the tractor 7 years and the 3 point arms have never leaked in the past. I have always had trouble with it coming out the vent in the back even when it's a little low. We do have hills I go up and down to mow etc. In the past I just wrapped a wrag around it to keep it from running down.

I made a overflow for my vent tube using a piece of hose and a radiator overflow style bottle. It works great and keeps the back end clean. When it starts getting some fluid in it I simply pour it back in.

Ok I know this is an old post but my F404 started leaking only from the left side 3Point control arm. I have called Affordable for parts but since I need a few other things I have to wait to verify them before just ordering the parts to fix this.

A couple of assumptions:
It has always had blow out the vent top so there is a vent tube on the vent pipe that goes into a collector.
I too like the OP had been filling to the top second line not the first line about 1/4 from the bottom of the stick


Lastly how do you replace these bushings and seals? Do you have to take the whole 3 point box off the 404? Or, can they be removed while installed on the unit and just pulled out the side? I do have the manual and can see the parts but its not clear if I have to remove all the shafts and guts first or can they be removed out the side

Thanks in advance for any guidance

You can replace the seals without removing the box, if you need to replace the bushings you will need to remove the top, because you have to get the lift shaft out of the way

Tommy,
Thanks I called in and talked to one of you guys this morning. I have a few more non related parts that I need to identify before ordering so I can order once.

Do you have a suggestion on the fill level? I keep a container back there with a tube on the overflow vent.. I bet I take a half gallon of overflow out every other month.

 

[Affordable]

Are you overfilling it ? We have a part that mounts to the roll bar you just extend some hose from the overflow tub,the part with the 2-holes goes down

I am not overfilling it on purpose but as stated above there are two lines on the dipstick.. I have always thought of the lowest one as the "hey not enough discontinue use until refilled line" and the upper one as the " this is the maximum full line". I keep it between there but it pukes out the breather quite regularly.. Some including Greg have noted they do not fill to the top line I was wondering if that was the facts or ?
