I think you'll need "worm-over" tuners.
Grover 309 are a solid choice.
Stew Mac has them for less than $60 right now

Grovers are good. And that's an excellent price.
I put Rubner tuners on my 305O (octave) and like them a lot. More expensive, especially the F style. However, I like the looks better. https://www.rubnertuners.com/worm-ov...-machines-new/

Looking for a smooth feel.
Every old to new Eastman 315 I'm seeing in a Google search is showing up with worm under tuners. Post a picture of the back of your headstock so you don't order the wrong tuners.
Stay away from Grover worm over tuners by the way. They turn backwards. Grover worm under tuners do turn the correct way but the shaft that the button is attached to might be shorter than your originals. Check the dimensions before you order them.

If you haven't seen the discussion on this site, have a look. I went through this process with a Collings MTO, a spot of work did wonders.

Paul's site is a great resource. If you want to see the difference between worm over and worm under tuners he shows it on this page.

A few years ago I owned a Eastman 315 and upgraded the tuners, with grovers if I remember correctly. I found that the bushings for the new tuners were smaller then the original bushings so I ended up installing spiral bushings in all the holes and reseating the new bushings to fit.

my vote is for Grover 309 tuners. I put them on my Eastman 305 & I love them. plus you can get a good deal on them if you do a little hunting on e bay.
Grover 309's are my vote

I just upgraded my Eastman 315 (2015) with Grover 309's from Stew Mac, worm under. Just had to drill a couple new holes for some of the screws in back. Much better, smoother tuning.

I've got them on a 315 and liked them so much I replaced the tuners on my Anderson A5 with 309's. They are 7/8 as good as Waverly IMHO for 1/10 the cost.
If I were going to upgrade tuners on a lower-end Eastman, I would contact them and ask what they are using on the high-end stuff. I used to own a 505 that had better tuners than my Collings. Pearl buttons and super smooth. I think they were Schallers, but that might not be right. And I'm not sure if that's what they are using anymore.

there reel fine my 309a's. I love them on my 305. the screw holes do not match up so you will have one little hole that you can leave alone or fill in with a tooth pick and a drop of wood stain
I really like the 315s I've played lately,and if you are keeping it even after a mandolin upgrade, it's a good modification. Your next mandolin should be of the Northfield, Weber, Collings ilk.

From what I've seen, one of those lower-end Eastmans with good and properly-functioning hardware could easily become a lifelong player. No need to automatically upgrade.

After playing my Eastman MD315 for nearly six months and doing all the extra steps to loosen up the tuners, a couple of the tuners are still stiff and irritating. I'm expecting to buy a good upgrade mandolin this summer, but I've played enough $2k to $6k mandolins in the last six months to feel that the MD315 is still good enough for a backup. With that in mind, I'm planning on upgrading the MD315 with a K&K internal pickup as well as some Grover 309 tuners (or maybe Rubner tuners, if they have the F-style tuners by the time I'm ready to purchase. The Rubner web page still shows "coming soon" and "Available in Late March" for the F-style worm under tuners.).

I was checking out the rubner website today but a lot of items are sold out. Are the going out of business?

Creativity is just doing something wierd and finding out others like it.
Grover 309's are 18:1 tuning ratio (the highest you can buy), Eastman's used to come stock with 14:1. 18:1 makes a huge difference, some other manufacturers OEM 16:1, but the modest (but good) Grovers beat most of them simply because of the ratio.
If you don't own a battery powered string winder you will want one with the higher ratio. :-)
