450S

It looks like there is enough threads left on the crank to measure the pitch with and a thread pitch gauge on Amazon is only a few bucks. Amazon - 52pcs Thread Pitch Gauge

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.

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 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 just finished extracting a broken exhaust stud from the head on my 450 by welding a washer and nut to it. I got lucky and didn't have to drill it out. Now that I am about to install the new OEM Honda studs I was wondering what does everyone else use for their exhaust studs, a thread locker, anti-seize or nothing?

Yes sir, the one in the middle is the original.

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?

@Fishfiles Yes sir, I did receive the backing plate today and it is in better shape than I expected, You are awesome and I cannot thank you enough!

Ok the donation has been made and the address pm sent, Thanks again!

Yes exactly, on mine someone broke most of the o-ring groove for the cover off trying to pry the drum off so water got inside and destroyed it

Looks perfect, please message me the details about where to make the donation!

I just re-read your post and you said plates, plural, which makes me think you mean front, but I need the rear brake backing plate, just to be clear and not waste your time.

Sounds great to me, Thanks

Are you saying there is a backing plate available for a $100 donation? Yes I would be happy to donate.

I have found a couple for 150 to 180 but still looking for something cheaper. I looked into the disc conversion but it said it requires 12” or larger wheels and mine are 11” so that makes it much more expensive
