I already did a search and didn't find anything on this topic. Do you people have any special ways of getting out the engine. I bent my Allen key trying and the screws didn't even budge. I tried a heat gun, that didn't work either. Do I have to use a torch?

Yea sometimes heating the chassis around the screws with a torch will work. Try tapping on the heads of the screws with a screw driver and a hammer, that can help get them free once in a while. If you end up stripping the allen heads out, get out a dremmel and cut a slot in the tips of the screws so you can use a flat head screw driver to turn them out.

why would a blowtorch help?

it has to do with the metalurgical properties reacting to heat. When meatal is heated up and cooled it expands and contracts, If you heat the metal it should contract and allow the bolts to loosen, You have to be very careful when doing this because any plastic pieces that are attached to the chassis may melt if you apply heat for too long.

Metal expands as it is heated. By heating the chassis plate, the hole will grow ever so slightly larger, allowing for the screws to be removed easier. I'd use a torch as a last resort though, getting open flames near any plastic is pushing your luck.

Buy proper hex wrenches, they do not strip out nearly as easily as the allen keys do. The associated hex wrenches have a hole through the top which allows you to stick hex key through it to increase leverage.

As someone mentioned, use a high-speed rotary tool and cut a slot into screws that will not come out.

Good luck.

Thanks for the advance I will try it.

Hmm I thought thats what I explained. [&:]

WAIT.

FIRST THING YOU DO: Go to the store and buy a set of high quality hex drivers/keys.
DO NOT EVER use the ones that come with kits.. they belong IN THE TRASH.

I'm not kidding.. It will save you so much trouble! You wont believe me till you try it..

It will cut your assembly time into half!

Hate to nit pick, but your statement was in fact wrong. Metal most definately expands as it is heated.

I'm gonna have to agree purchase the best tools that you can afford , it'll be worth it in the long run, RED

I agree, but you can get a cheap set at home depot or something, they work but just not as well.

I hate to be rude but..... Read my first post!!!

It also has to do with what metal your heating as every metal is different!

Read the next sentence of your post, you clearly state it would contract, which is most definately wrong. I'm sure there may be a few exceptions, but for aluminum, and most any other general common metal, it will surely expand.
