1500D Knuckle seal mess

Hi everyone,
Both of my knuckle seals are leaking. I took the left one off first, only to find that the seal seems to be welded to the upper cover. I have tried everything I know to get it off. Upon closer inspection the cover must have got hit with a boulder or something ( I live in the mountains) so now I need a new cover. My question lies in that i pulled the shaft out to try and get at the seal better. Will the shaft come out just by removing the retaining clip on the gear? Or is there something else to do with the bearing in the cover I should know about? Also, what is the best way to remove the bearing to replace it in the new cover?
Any and all help will be greatly appreciated!

P.S. after all this I am almost scare to take off the other side <E>:)</E>
 
Have you gone to the parts diagrams on this sight? Nice drawings showing how it goes together. Just click on the parts block above and take off. Not meaning to avoid your question. Just not sure you have been to the drawings.
 
Hey Winston glad to hear from you!

I have been to the diagram and it looks like if i take the retainer clip off the shaft it should pull out correct? That solves one issue:) my other question is what is the best way to get the bearing in the knuckle cover out? Need to have that for the new cover.

thanks,!
 
If I am correct in thinking you are wanting to remove the spindle from the lower housing then after removing the lower bolts and then snap ring #56 it sure looks like it should slide down through the rest of the parts. Never done it on your model so not sure. We are talking red here?
that upper bearing will not be expensive, however, it should tap out easy from the top if you work back and forth gently side to side.
 
Sorry Winston my bad, yes we are talking red. However my question relates to clip#47, bearing#48 and shaft#43 on the internal red diagram. Any thought would be appreciated, thanks!
 
I guess I am off in left field. #43, 47, 48 are all on the axle shaft. I thought you were working on the knuckle seal and related parts.
 
I am also confused. #43, 47, 48 do not come off with the knuckle.

Ok guys maybe i have confused you, for that I apologize. I was having such a tough time getting the knuckle seal out I pulled out the axle with the knuckle cover so I could get at it better, so now I have an axle a knuckle cover attached to it with the gear #44 and the bearing #48 Keeping me from separating the knuckle cover so can replace it. I am looking for advice on removing the gear and bearing.

Again my apologies.

Still not sure I am understanding. if you are having to replace #34 then remove bolts #37 to remove #34.

I am understanding #s44 &amp; 48 are on the internal red. Your first post stated you needed to replace the upper cover. I am thinking the upper cover is #34 on the red external drawing, Is that correct?
 
If you remove bolts #37 on the external drawing you can separate the knuckle cover and axle housing. Have you done that?
 
Hey Winston, Merry Christmas!
Yes I have removed the axle from the knuckle cover, was worried the bearing in the knuckle cover would not come out, but I got it out. i am now waiting for my new knuckle cover to arrive, with the knuckle seal and the bearing already in it.

Should I be able to slide the axle right back into the housing when I am reassembling everything or is there a trick to it?
really appreciate all your feedback and patience with me.
thanks!
 
Have not been there, done that, but looking at the drawings, I would say the axle should slide right through the axle housing and might have to turn a little to line the splines up but should slide right into the ring gear. Hope that is what you are asking. Merry Christmas to your and yours also!
 
Aaron and Winston,

Ok hopefully last question. Aaron was kind enough to send me a new knuckle cover with the knuckle seal already installed as well as the knuckle cover seal and bearing. My question is from looking at the red 4wd internal drawing and seeing the placement of the LH top knuckle washer, is the seal shown below it (part 50) the one already installed in my cover? There is not one on the spindle shaft and I do not recall taking one off. Otherwise it looks like the washer will be riding metal on metal. Hope this isn't to confusing. Hoping Aaron remembers the install and can help.

Thanks,
Paul Mott, ( In case Aaron needs to look up the order
 
Aaron, thanks for the quick reply on my last post. So I am attempting to get everything back together and I forgot the trick to getting the gearbox and the axel gear to mesh. I have a jack under the gear box and have tried every angle and height, not sure why they won't mesh.. Thoughts?

Thanks in advance,
Paul
 
Winston,

Saw you were online. Any thoughts on my question about getting the gears to mesh on the left side of my 1500D after knuckle seal replacement?


thanks in advance for any thoughts,
Paul
 
Winston,

I hope this helps:

On the external drawing I am raising #39 Lower left hand knuckle housing up into the knuckle cover to mesh #54 and 44 to complete the repair. I remember from last time it would only fit one way but I can't seem to find that way.
Any help would be appreciated,
Paul
 
other than turning a small amount to allow teeth to match I don't know. Are you confident it is the gears holding it apart and not the seal trying to start on? How much does it lack going up?
 
Winston,

It is about a 3/4" gap between the upper and lower. Using your thought about the seal starting I took the whole unit off the tractor and made sure the top and bottom were line up. Put the Unit back on and using a jack , I basically lifted the whole front end in hopes that the pressure would make the units come together properly but it did not move more than a 1/4". I can't figure out why it won't go together. Any further thoughts on how to?
 
I don't have an answer for you. I don't think forcing it with a jack is the answer. Are you confident that top bearing is correct? (6204) Assuming the spindle shaft is sticking through the top enough so you can wiggle or move it a little as you try to move upward with the assembly?
 
Winston,

Aaron installed the top bearing for me so it should be right. However, the lower unit will not even go up into the knuckle cover far enough to engage the drive gear in it. And yes the spindle does go up and through the knuckle cover. I noticed on the other side their is about a 1/4" gap showing between the upper and lower unit so I assume I am about a 1/2" from getting the left side sealed. I am at a loss, I hope Aaron can help me, big snow coming in the next couple of days and need to have this back together and working. thanks for your thoughts.
 
These types of things are very difficult to diagnose from a distance. Pictures might help though. I would try to assemble it with different pieces taken out to see what part is causing the holdup.
