I just had both wheel motors & pumps replaced at dealer. After cutting a couple lawns I noticed oil leaking on inside of rim. It turns out it is leaking at the fittings that connects to the wheel motor. They didn't seem real tight so I tightened them a little with no luck. How much force can I put on these to tighten them? Can I put a little teflon Tape on them? I was hoping I didn't have to take back to dealer Monday. I really need to get back to work with this mower.
