Hello all!

Recommended Posts

I want to say thanks to @Goober , as he sent and I just received some 300 parts , which included something I really needed to finish the blue 300 that I gave my son in law ,   Goober sent me a  brand new master rebuild kit and a good used plunder and  carb primer ----  @shadetree  calls it " passing it on " --- me and Jeep have swapped out parts a few times now

Well my rear brake backing plate problems persist.  I finally got around to trying to replace the backing plate today but when I disassembled everything, I found that mine is quite different that the replacement one.

 

On mine the brake shoes mount to two posts and the replacement backing plate does not have these posts, so the new brake shoes will not fit.  Thinking I might just be able to find different brake shoes and still make the replacement backing plate work I continued trying to mount it to the axle housing, but I found that the bolt pattern is quite different between the two backing plates.  I didn't waste time measuring the bearing sizes to see if they were the same.  So it looks like this backing plate is off of some other year or more likely size than the 450.

I am thinking I might just have to try and get the old backing plate welded up around the o-ring groove and see how well I can shape it with a dremel or a small cut-off wheel in a grinder.

 

Anyone else ever have to do this?  Any other ideas?

Post a few pics of your rear end.  The one without posts is, I believe, maybe a 300 backing plate.

in the past, i have used jb weld on the backing plate to build up the area where the large o-ring sits in. then smoothed it down with my dremel tool. pretty easy to do. DO NOT TRY TO WELD ANYTHING TO THE BACKING PLATE !!..its not something that takes to welding.

Good info here.  I thought pretty much all the backing plates had the same bolt pattern where they attach, but in this thread we learn the 300 is different.

 

If Fishfiles can't get you a good one, I can dig and see what I have in the stash.  We won't leave you hanging.

Here are the pics for you.  I am afraid it looks like water has been inside the housing, look at the last picture and see the rust on the shaft inside.

I am going to be sending you back the first one, perhaps you can help someone else out with it in the future.  I would be happy to cover the shipping of the second one, just not sure how to do that.

Here is a pic of the back side of the plates for reference.

 

The bottom one is the original 2000 TRX450S, there is also a slight difference in the clocking angle of the cable mount.
