Default Warrior 350 stator cover holes beat

My problem is the stator cover on my warrior 350 is leaking oil. I got it s a project quad and had to replace the stator and other various components within that cover. From taking it off so much, the holes for the main mounting bolts have become worn out and the threads are beat and the bolts no longer tighten hard, they just spin loosly inside there, not enough to put pressure on the gasket and keep oil from leaking.

I need a solution for this. My best guess was to go to Lowes and buy bolts of the same length by slightly bigger is diameter and force them into where the other bolts were. Is this a good solution? Thanks!

if you do that run a threader into the holes first to sharpen up the threads another option would be to drill it to the next size and re thread it

Just buying larger bolts and forcing them in will not work. You will have to rethread the holes to the exact size of the new larger bolts. You must be gentle and not over-tighten the bolts! The aluminum strips out very easily!

What is wrong with degreasing the bolts and holes and applying a little rtv silicone to the threads before installing them?

You can always tap them bigger later if you really need to

Hmmm.. So the larger bolt idea might not be a great idea? What is this silicon? Will it allow me to tighten the bolts tight enough to seal the gasket?

its like a rubbery gasket sealer it will not allow you to tighten them it will just hols them in place once tightened it helps seal gaskets but you can not use any amount of torque on it the bolt will pull right through it

Ok I did not realize you were saying the threads are stripped out (or nearly stripped) It is common practice to use silicone on some bolts if you don't want a fluid to leak though the thread. Like on a cylinder head on a V8.
However silicone is not a repair for a worn out or stripped thread.
You have 2 options, buy a tap and and tap to the next larger size, or buy a heli coil kit to repair the thread. Sorry for the confusion.

Just Heli coil it and be done with it.......the correct way.

Ok, so I just checked out this heli-coil stuff online. So basically how the heli-coil works is I tap out the hole to a size slightly larger, then install an insert that reduces the size so that I can install the original size bolts?

If that the case, wouldn't that essentially be the same as installing slightly larger bolts anyways?

yes and no mostly no. the coil gives you the correct threading (KEY) either way you need to tap it to get the threading that you need. so the decision is yours re tap it and use the helicoil and reuse the bolts you have or bore it and retap it and use a larger bolt. I would say use the helicoil so your using the same size bolt as going to a bigger size you will also need to make the cover holes bigger
