';How do you replace the front sprocket oil seal on your 1982 honda xr 500?

You can remove and install a new seal from the outside. The seal is pressed in from the outside and the bearing is pressed in from the inside. The case does not have to be split. Drill a couple of small holes in the seal body, not the seal lip, to allow you to work the seal out with a right angle scribe.';How do you replace the front sprocket oil seal on your 1982 honda xr 500?
Sorry to be the bearer of bad news.


The crankcase has to he split to remove and install the countershaft seal.


The seal has a raised ring around the outside if it.


The ring sits in a groove in the crankcase, so the seal won't accidentally pop out.


If you plan on doing the work yourself, I'd advise you to get a shop manual.


The front %26amp; rear counter balancers are tricky to time.


And if you've never taken the top end off of an XR, the cam chain tensioner will really confuse you.


Good luck.

The seal and bearing on this model are not pressed into the crankcase.


That's the design of most dirt bikes and 2 cycle engines whereas the crankcase is split vertically.


Your model, 1982 XR500R, the crankcase is split horizontally like most street bike engines.

Go to - your bike - Rear Balancer


The crankshaft bearing has a ring that holds it in place - that's proof 1 that the bearing is not pressed in.


The seal doesn't have a flat surface around the outside of it - that's proof 2 that the seal isn't pressed in.


Go to - Crankcase


Look at the lower crankcase half #3


The half circle at the rear, is where the countershaft bearing %26amp; seal sit.


If you zoom in, you'll see 2 grooves.


The inner groove is for the ring that holds the bearing in place and the outer groove is for the countershaft seal - that's proof 3 that the seal isn't pressed in.





For anyone that reads this -


This is another reason of the importance of owning a service manual. Why trust answers you get from strangers when you can have the answer to every one of your questions right in front of you. Would you rather spend $35 for a service manual, or up to and over $500 when you make a mistake? There are 2 totally different answers to this question. Which one are you going to believe? Why not ask the person that designed the engine - Mr Honda :)
