CRF's Only Forums

Hi, I'm new here. I have a 2004 crf 450R and just replaced the countershaft seal in it. I pulled the old one out; it took awhile and came out in bits. It was the original, i'm guessing.

I cleaned it out real well, using various picks and a razor blade to remove any tiny bits left.
I greased the new one up and installed it and took it for a ride.

I noticed a little oil around the sprocket/on the frame after I was done. Is it normal to leak a little after initial install, or is something else up?

I hope it's nothing, but I wanted to ask.
Thanks!

There are actually 2 seals oil seal part 33 and D-ring seal part 32. Did you replace both?

I only replaced the one seal. However, I picked up the other one on the way home from work, and I'll install it this evening.

My concern is that I didn't damage anything in the seal mounting area. I used a couple small picks and a razor to clean the old one out, since it came out in little pieces. I never used a hammer or anything like that. Just firm pressure on the picks and blade. I swapped out the fluids and when I was done, just to make sure the tranny oil had nothing foreign in it.

Thanks for the fast responses. Hopefully, it'll just be this little seal.

Hey, just wanted to drop a quick thanks to everyone for their help. I replaced that "d-ring" seal inside the countershaft collar, and it worked great!
I didn't notice any fluid around the countershaft!
One other thing i noticed, there was some "rub" marks around the area where the countershaft seal went. I'm guessing this is from an aftermarket sprocket that was on it at one point? I applied a little JB weld to the area and tapered it to match the factory case lines.

Hey, no problem, and welcome to Crf's Only. That rub mark was probably from an O-ring chain. They are wider and without the correct spacer will rub on the case.

Let me ask you guys a question....I'm working on the same issue....#33 in the photo is the big, outer seal right?

I pulled the metal collar off, then the little d-ring/o-ring thing that affixed to the shaft inside. The bigger black seal I'm referencing is being very difficult....I'm hope this thing comes out because I just took a couple chunks off it trying to get it out...and it's not budging...please tell me I didn't just do something stupid, by jacking this thing up....

Nope. It's just being a bugger. Keep working. Just don't damage the surface of the case it seals against!!

I spent probably about 45 minutes, no lie getting mine out. It definitely came out in bits. The best tip I can give is to take a sharp razor blade with a nice, small pointed tip and gently but firmly work it around the seal groove. I had a soft bristle brush and cleaning solvent that I frequently brushed into the seal area to flush away any loose tiny chunks.

That's why I changed my transmission oil when I was done.

It's a PITA, and I too thought that I might have messed it up, but as long as you're careful not to use too much force, it'll be fine. I used a large diameter socket and plastic mallet and tapped the new (well lubed)seal squarely into the seal mounting groove. Haven't had a drop since.

got it out...thanks.

He was looking at this post. I too need to replace my seal and dring seal I have a 2004 CRF 250X by the way.....

Anybody know where I can buy them that wont cost me almost $18.00 to ship ( seriously for 2 small parts that fit in an envelope and cost $6.95!)

You can purchase them on our OEM parts website at www.yeltrik.com. Just mention in the order notes to ship them the least expensive method. Often this is USPS and is uninsured. So, any loss or damage en route would be your responsibility.
