Can you smooth out a pinion gear

[Lunker Larry]

I was wondering if there is a way to smooth out a pinion gear or any gear for that matter. Working on a Lexa 300 and Daiwa says the pinion is no longer available and no substitute. The reel is fully fishable but has a buzz. I've filed gears that were no longer available with moderate success but was wondering if using jewelers rouge or automotive rubbing compound and a toothbrush or something would make a difference.
I'm sure there are a few here that have tried everything and may save me the effort.

I can't imagine filing a gear would work very well. But is impossible t change both the pinion and the main gear? Perhaps installing the complete gear set from a current reel would work.

I used automotive valve lapping compound on a set of noisy gears on a Penn GLS25 recently.  Worked pretty well, reduced the noise by 50%.  Butt be careful it's very aggressive stuff.  You can see where the compound was working and thinned the working surfaces of the gears.  I'm not 100% satisfied with the gears so ordered a new set.  Maybe if I worked them some more it would be acceptable but there is the risk of taking too much off the gear teeth.  The main and pinion are both SS.  Bill

Assuming there is concurrent wear on the main, wouldn't the main need to be filed to match in order to reduce noise?  I'm sure you are fond of the reel, but sounds like end-of-life is approaching.  I imagine the work you are looking at would be very tedious and needs magnification.  Especially if you consider jewelers files and such.  I would be on a serious hunt for a donor, bolt-on upgrade, something to keep your reel alive. 

Try Mat's Reel Repair.  Use the online request form, give him the part #'s of everything you think you might need for that reel for as long as you live.  He pulled a few rare rabbits out of his hat for me.  GOTTA have part #'s though.  The last time I called over there, Mat answered the phone.  An actual human said hello.

Not my reel. Servicing it.
I've managed to quiet down a number of reels by lightly filing both gears and it takes very little time. Have a V shaped file and a light touch. Of course it doesn't make them silky smooth but it does make them fishable and not sound like a coffee grinder. Often they're quieter and smoother at the end of the season as they wear in. I've been very surprised sometimes.
If the reel is no longer supported and the owner wants to keep it going you do what you gotta do 😁
No cheap doner Muskie reels.

I'll look into the valve lapping compound. Thanks for the tip and everyone's suggestions,

Filing the pinion greatly reduces the life of the main and pinion gear.

Fine lapping compound works but plan on replacing bearings BEFORE using the reel and make sure 100% + of the lapping compound is washed out of the reel.

Just noticed you're in Canada.  Try Reel Restorations in Comox Valley BC.  He may have replacement gears for the reel.  He bought out an inventory from a closed shop in Vancouver.  Lots of discontinued stuff.  I just got some very scarce spools from him.

tough one.  generally, the answer is no. 

[Lunker Larry]

looked at some lapping compound and it is scarily abrasive so that's out of the question.
I hate it but sometimes you just have to give in

You can try tooth paste or jewelers rouge.  Not nearly as abrasive.  Bill
