Honda HR215 Masters Oil Leak
I recently obtained a Honda HR215 SX Masters mower. It works great but I discovered an oil leak. I cleaned the engine very thoroughly and then ran it to locate the exact point of leakage. The oil leaked from the bottom of the oil fill tube so I replaced the lower "O"-ring which stopped that leak. However, I then noticed some oil on the upper portion of the engine which must be leaking from the top of the engine. It appears that this oil might be leaking through the crankshaft oil seal at the top of the engine. I must remove the flywheel to more closely inspect to see if there's oil around the crankshaft, and if so, then the oil seal is probably leaking.
1) So far, I've progressed to the point of removing the nut which holds on the flywheel, using an air impact wrench. The next step is to remove the flywheel itself, and here's where I would appreciate some advice. My plan is to borrow my cousin's 3-arm universal puller which has "J" hooks at the end of each arm, which should grab onto the under edge of the flywheel while turning the center bolt against the crankshaft. Is this the best tool to use? Are there any other suggestions for the flywheel removal? Also - must the ignition magneto, which is very close to the flywheel, be removed 1st?
2) When reinstalling the flywheel, what torque should the flywheel hold down nut be tightened to? Also, what's the best method to prevent the crankshaft from rotating while torque-ing down the nut?
I'll be out-of-town for 2-weeks starting in 2-days, so I won't be resuming this project, nor reading any comments in this thread, until I return. Any helpful suggestions will be greatly appreciated.
