I have a JD #5 mower that leaks on the pitman arm shaft. I want to fix this before I need it. I am assuming it is packing and not a regular seal. How do I remove the pitman arm balancer, if that is what you call it. Any help would be appreciated.

Thanks,

Yep, it's a plain old oil seal. Not a silly packing. The tapered key is the only thing that holds the flywheel on, some have had good luck to drill and tap the key and use a slide hammer arrangement to pull the key out. Then the flywheel should come right off if it's not rusted on. That's what the oil leak is good for, keeps stuff from rusting!!!!! Have fun.

Checked the parts book for a number 5 (my operator's manuel has one in it) It appears to be a seal instead of a packing. The flywheel usually comes off when you don't want it to. You might be able to tap it in a bit to loosten key then pull it off. If you use the puller, I would pull it a ways, then tap it back in and pull key, I think the key is supposed to have an outer shoulder on it. I have replaced this seal on my number 5 also. Good luck on it, they are a good mower.

It's called the flywheel. Use a good 3 jaw puller and pull the flywheel off. A tapered key holds the flywheel on the shaft.

I have a #9 mower that had the same problem. I took it apart by removing the pitman and then the round balancer by just removing a few nuts and bolts and pins. My leak was coming from the chain housing through a failed seal on a bearing. Went to a John Deere dealership and had the replacemant parts the next day. I would recommend a parts manual for you mower if tyou don't have one. It really, REALLY helped me out!!!
