John Deere pinion gear!

Good afternoon,
I'll try to keep this short.
I have a JD JX75 & took the pinion gear off the rear shaft first I had to remove the snap ring then there is a washer then the pinion gear. One side no problem other side rusted why well the plastic shield that keep grass & crud out was broken. Now this pinion gear has groves inside of it it's like a ramp that the shaft key (spring operated) rides up the ramp & drops into a grove in the gear.
Got it out cleaned it all up now I'm ready to put her back together. What I would like to know is does anyone think it would hurt to put a little tranny fluid or power steering fluid some kind of lubricant inside the pinion gear? Reason being is without this shat key riding up & down it's a bear to pull back the mower & I really do not trust the plastic shields
Or if anyone can come up with anything else I just don't want it to be to thick of a lubricant.
Thank you!

Hi Grumpy

I am not certain about your exact mower but similar ratcheting type wheels/drives n such I have found to keep dry.
Specifically transmission or power steering fluids are not lubricants they are hydraulic fluids and as such are corrosive. Ever spilled brake fluid on a painted fender....?

Besides the tension and resistance in any lubricant you might use, it also collects and holds dirt/debris/grass....etc.

You can soak the keys and parts (not plastic) in some tranny fluid to help in cleaning, but then I would wipe and let dry.
