Default She's stuck Captain

I have a small issue on my MBX5T chassis.

The engine mount screws from underneath are locked, hard.

I'm trying to remove the engine mount from the chassis and I'm either going to snap my hex driver or the screws are going to strip.

This is a used vehicle I bought so I do not know how the previous over locked them down. For all I know he glued them in

Any tips/tricks to loosen those screws without breaking something?

I suppose I could always just leave them in, but then I'd have no way to adjust mesh if I use different size clutch bells.

tyvm in advance.

if they are the stock mounts try to get one out of each if you can, the your move the mount back and forth to loosen the other one.

I hear alot of people have had great success using a heat gun (or hairdryer) on the mounts (make sure you heat the mounts and not the chassis).

If they are that rusted in there slotting with a dremmel might not work. But honestly i would try loosing it up with a wrench and see what happens first.

And if none of that works, break out the drill and drill the head until the cap comes off and you can take the rest of the screw out with plyers.

Heat em up as much as you can. a Good soldering iron sometimes helps....get it hot and hold it on the head of the screw until it breaks loose. You could always cut a slot in them too and use a big screwdriver to try and get them to break free. Previous owner may have used red loctite?

So heating up the screws with a soldering iron may work huh?

I can give that a try tonight. I've always thought heat would swell the metal and make things tighter. But I've been wrong before

Thanks for the help both of ya!

Applying Heat will break down the loctite, that should help remove screws.

IF there was locktite used. My bet is rust. Guy sells it, no telling how long it was sitting there.

If heat does not work then try some penetrating fluid or a blowtorch.

You need to do some forearm workouts for about two weeks. I'd recommend the extreme hand grips. Get jacked, then attack those damn screws!

I was going to suggest the same. If heat fails...it's probably rusted in there so penetrating oil will help loosen things up. If all else fails....you'll have to drill em out.

grab your wrench with a channel lock and give it hell. after heating up loctite. if you strip the screw then cut a slot in the screw head w/ a dremel and use a flat head driver.

Get an easy-out bit, it comes with 2 bits small and big.

1 side of the bit cleans the area it just drills it clean and stuff

The other side is like a thread and you put it in reverse and it pulls it right out.
It only like 30$ for the 2 bits

This has happened on my 8ight buggy before and I used that tool.

Forgot to mention this will ruin your bolt you wont be able to use it again.

This way only works if you have a spare bolt ^^

Like they said ....heat,but just enough to break it loose.
I use a micro torch and apply heat directly to the bolt/screw for about 10 to 15 seconds...you will see the moisture dissapate from the area and its ready.I have used the heat gun but with the micro torch it narrows down the area being heated...my 2 cents

Try tapping the end of your wrench with a hammer, this works for me.
