OZM29C Posted April 11, 2020 Share Posted April 11, 2020 Is there a special technique to stop the lip of an OEM leather bogey wheel seal rolling in on itself when assembling the bogey wheel? I have had the seals soaking in oil for about two days before trying to install them. I have kneeded the leather to make it more supple. I have placed the seal on a size for size mandrell to try and stretch the leather before fitting So far none of these actions have met with success. I think that I will fit the modern CR seal if I can't find a solution to this problem. Quote Link to comment Share on other sites More sharing options...
M29 Posted April 11, 2020 Share Posted April 11, 2020 Hi John What is your thinking regarding the new version seal versus the old leather style? I recently went through some bogey refurbishment and like the CR seals better than the old leather ones. I have numerous old style seals and never saw one do as you show in your picture. My understanding .when installing the new seals is the lip faces out. Dan Bogie info Dec18.pdf 1 Quote Link to comment Share on other sites More sharing options...

OZM29C Posted April 21, 2020 Author Share Posted April 21, 2020 Here is a photo of the special installation tool I made to install the OEM bogey wheel seals to prevent the seal lip from rolling back. I will post photos of this tool in use when I have enough hardware together to assemble another bogey wheel set. I had to come up with something to install the OEM leather seals as I was quoted $536.80 for a replacement set of 32 CR12391 seals. Quote Link to comment Share on other sites More sharing options...
OZM29C Posted April 24, 2020 Author Share Posted April 24, 2020 I put this up on the Weasel FB group but I think its important to make sure that the info is also captured here on this forum. First off I lay the split collar on the inside of the bogey wheel. Quote Link to comment Share on other sites More sharing options...
OZM29C Posted April 24, 2020 Author Share Posted April 24, 2020 Then I pushed the plastic dust cap into the seal to expand it. Quote Link to comment Share on other sites More sharing options...

OZM29C Posted April 24, 2020 Author Share Posted April 24, 2020 Its time to gently prise the plastic dust cap out of the seal. Quote Link to comment Share on other sites More sharing options...

OZM29C Posted April 24, 2020 Author Share Posted April 24, 2020 Here's where it pays to exercise a bit of caution. Don't let the bogey wheel disengage from the seal or else the seal has to be removed from the bearing carrier and the whole process starts again. Having said that a tiny bit of slack is needed to remove the split collar. Quote Link to comment Share on other sites More sharing options...
OZM29C Posted April 24, 2020 Author Share Posted April 24, 2020 Insert the shims, shaft collar, bearing and woodruff key and then repeat the above for the opposite side bogey wheel. Quote Link to comment Share on other sites More sharing options...

Jim Gilmore Posted April 24, 2020 Share Posted April 24, 2020 John, You did put these seals in the right way ( which is the wrong way for most other applications ) right...? I can't tell from the photos ....the "lip" of the seal should point out of the hub towards the bogie wheel.......and the back part with the rubber/leather seal should be on the inside. This is backwards from the way most seals are installed. On most applications the seal keeps the grease/oil in and water/dirt out. On the Weasel the seal is supposed to let grease out when it is pumped into the bearings and housing. This is to allow the new grease to push water out of the housing/bearings when the vehicle is driven or swam in water. This was part of the after-swimming PM on the vehicle. See TM 9-1772, page 243 for an example. Jim Quote Link to comment Share on other sites More sharing options...
OZM29C Posted April 25, 2020 Author Share Posted April 25, 2020 @Jim Gilmore The seals are indeed installed back the front. Thats why I have had to go to all this trouble to install them. Quote Link to comment Share on other sites More sharing options...

Jim Gilmore Posted April 25, 2020 Share Posted April 25, 2020 John, I was sure you did but just wanted to point it out to anyone else that installs them... 🙂 Quote Link to comment Share on other sites More sharing options...
D.R.H. Posted April 26, 2020 Share Posted April 26, 2020 (edited) I for one really appreciate this bit of education. It makes perfect sense regarding which way to properly install the seals. Thanks Oz! I also did a bit of poking around online and found this; https://www.motionindustries.com/shoppingCart.jsp?BUS_ACTION=review. While the Aussie Dollar differs from the U.S. Dollar, I think this price of $336.00 is fairly reasonable for 32 seals. Edited April 26, 2020 by D.R.H.
