did u get the sleeve n seal ?

Sleeve's and seal's were shipped yesterday.

watch the outside diameter on the spindle, not sure what your ser # is but I had a difficult time with the sleeve fitting over the spindle, got leaks on both sides ? If you end up w the same problem, there are tighter fitting seals that work well, also check the tower that the spindle goes up into to make sure it will accommodate the sleeve....

So far all everything matches the old style as listed on Hoye's web site. Everything I have ordered has been correct. Messed up and ordered the original seals before I had it completely tore down. My mistake. When I discovered the rust and groves had to reorder. I haven't found the serial#.

Received the seal collars today and they look to be a perfect fit. Should I put RTV on the spindle before I put them on. The collar has rubber seal material inside of them.

Started the repair today and everthing was going good till I discovered the new repair collar is a larger diameter than the opening in the drive housing. The bad part is I had allready installed the seals. I think I was able to get the seals out with out damaging them.

going to see how you're repair turns out... I have a little weep in that area. (I think mine is the same area). I would have to see a pic of both parts you are repairing to know if mine is the same area. I hope it works out for you

The seal collar has rubber seal material iside it. Had to clean up the old seal area with brass wheel and 320 crankshaft cloth seem to fit very well. After you installing the collar the opening in the drive gear housing is to small to go over it. Going to take it to a machine shop and have it drilled large enough to pass over the seal collar. The seal collar is 64mm and I dont have any way to bore something that large.

Well, If I have to have the front gear case housing bored so that the bushing will fit. I'll just put up with the weep. You will most likely have to take all the gears out of the gear case housing to have the hole bored out

Maybe I am missing something here, but normally isn't the housing installed before the collar and seal, (or never removed)? I have never heard of this problem. The only thing that should fit over the collar is the flexible part of the seal itself.

Normally, I don't they don't have a collar.(my 3110D don't) The collar must be some type of repair part. The seal goes into the gear case housing. I have replaced my seals a couple of times. I guess mud , etc, gets in that area and screws up the seal,,,& the seals start to seep a little oil. I had to remove the gears to get the seal installed

Yes, the collar is normally a repair part to repair a groove worn in the shaft. Are you familiar with "Speedi-sleeve"? Either use a sleeve/collar or install the seal slightly further in or out from the groove.

R Barger · Sep 1, 2014

That's correct but the teardown is not that complicated. Be sure you tear it down completely before you order parts. Tear down is about 45 min. to an hour per side.

Only problem the seal is, it goes into a seated area in the gear case. there's no way to install it farther in or out of a grove. It goes into a milled out area in the gear case for the steel part of the seal to sit on. You have to split the gear / hub case and remove the gears to get the seal into place. I don't know if speedi sleeve would work or not.. Never heard of it. If the spindle ?? the machined part that fits into the gear case housing seal is worn just a little it will weep oil. the speedi sleeve would have to be very thin on the outside to fit into the seal

The one picture above is after the repair sleeve is installed. The sleeve increased the spindle housing from 60mm to 64mm. This is why the the gear housing opening has to be bored out a little.

grainger12002 · Sep 2, 2014

that's the same issue I had when doing the identical repair. I did reem one side to fit the collar, the other was able to seal . There are many seal options, this discovered after much research, glad its going well for you R Barger

I bet you used the wrong seal.

its the housing that's too small, the seal fits either way its the speedi sleeve, that once installed, makes the spindle not fit in the housing. All the seals are the same outside dia. just the inside is available in many size options
