Yes. Once you remove the engine cover and expose the shaft and seal, carefully pry the old seal out with a small flat blade screwdriver. Apply some grease to the inside diameter of the new seal, slide it over the shift shaft (clean it first) - and press it in place.

I have a 2005 CRF 80. The shift lever has stripped the knerling on the shift rod coming from the gear box. Is this a difficult repair or can the shift lever be welded on?

To fix it properly you need to strip the engine You can just weld it on but cool with water as the seal will melt It isn't good welding it on as they do tend to snap the weld sooner or later. But nothing to loose if it keeps breaking you just replace the worn shaft anyway

Oil is leaking from the shifter shaft on my 2005 1200R. Is there a seal or bushing that needs to be replaced?

There is a seal right behind the shifter. You can replace this seal without having to pull anything more than the shift lever off the shaft. Loosen and remove the bolt. Mark the case or something so that you can remember where to put the shifter back on and remove the shifter from the shaft. Using a screwdriver slip it between the seal and the shaft and work the seal out of the cover. Try not to scar up the shaft or the case. Once you have it out, slip the new seal over the shaft with it facing in the propter direction and use a deep well socket or something to drive the new seal into the cover. Replace the shifter and put the bolt back in. This should stop your leak.

Good Luck

My 04 crf 450 is leaking oil out of the air box breather

Hi, Jmattison21 and the usual suspects are:
1. Oil tank/system overfilled.
2. Faulty breather valve.
3. Engine breather hose bent, pinched, kinked etc.
4. Air filter has too much "pre-oil".
5. Crankshaft seal failure allowing transmission fluid to migrate.
6. Blow by drain tube cracked/split or filled to capacity.

I have an oil leak at the gear shifter how do you replace the rubber seal 1995 honda goldwing se craig

Putting it bluntly, remove the case cover, pry the old seal out any way you can without buggering up the case then slide a new seal onto the shift shaft and seat it in the cavity. The only other way is to remove the shift shaft and then pry out the old seal. Sort of the same thing but a bit more mannerly.
