Z500 Power Steering Leak?
« on: April 18, 2021, 09:51:58 AM »
So I noticed with first ride of the year yesterday my EPS was stiff for the first minute of riding then started working fine.   I also noticed what appears to be fluid leaking from the power steering box (see picture).   No EPS error lights on the dash are lit.    I assume these are sealed pumps with no access to fluid?       My assumption is this is a leak of some sort however I also had mice nesting in my hood storage compartment over the winter in storage.  There was so much piss (looked like black oil) in the storage compartment and it was draining through the drain slot and was dripping right onto the EPS unit.  So I am unsure if this is power steering fluid/grease or mouse piss.

Power steering is electric and on the steering column under the dash. Below that is the rack and pinion which does have some grease in it but no oil of any kind. Look up a bit higher to the brake's master cylinder and see if there's a leak there dripping down.
It's likely mice/rats have eaten a big mess into the electrical harness is many places.

NMKawierider, thank you for the response.   I knew it was electric, just didn't know about the rack and pinion and if it had seals that could leak any fluids (fluids that can drip, not grease).  Will be cleaning this up next time I can access the storage and should be able to see if there is anything else.   Machine rode good with no other issues so I assume wiring is all intact.   Dam mices!
