Front mail seal replacement on 22RE

Front main seal replacement on 22RE

I didn't find anything on the tech link and search.

Do I need to take the chain off (I believe this engine is chain driven) to replace the front seal? I got oil flying everywhere in the front. I have done work on belt driven, but not chain. It looks like all I need to do is taking off the pully. Could someone confirm or give me some directions, tips etc. Thank you.

Remove pulley and oil pump - that should be it. No need to remove t-chain.

It can be done by just removing the pulley if you have a hook type seal puller like used for a motorcycle fork seal and a driver big enough to install the new seal. Otherwise do like bkg said and pull the pump off.

Thanks.

To break the bolt loose, prop the breaker bar against the framerail. Pull the coil wire and give it a bump.
I always use a screwdriver very carefully to pry the seal away. A socket will drive the new one home.
Easy twenty minute job.
