Gears in the oven?!?!?!?!

[rik]

ok, so we all know about the tranny problem. hey, it is what it is. and i am gonna assume that we have vented our frustrations by now and are over it. again, it is what it is......so here's what i'm thinkin. :idea: .i gots me a spare set of tranny gears from HH that are very warped and i aint using them. so today i machined a flat piece of steel and i'm gonna throw it in the oven with the warped gears on it. hopefully, the warped gears will then lay flat. i dunno how well it will work or if it will work at all. ..just gonna gradually increase the oven temp until the gears become soft. or maybe use the broiler and the top rack so i can "flash" heat them.

i've done this before on plastics i've machined, but in a controlled environment..

will keep all posted on the results...

I think it would be best to preheat the oven first because its so small.
Maybe 350 or 450,Then place the part in.
That's the way I usually deal with small or thin plastics. Its also how many take apart head light lenses in modern cars.

cool, i'll start there! i'll just try one gear at a time until it works or i destroy all the gears. thanks for the input...

i've converted domestic car lenses to the euro style by using a heat gun and carefully removing the red lens. i just figured that if i used a heat gun i would melt the gear...(i only have a cheap-o heat gun with two positions..off and on, on being = to the surface of the sun!)

Oh my my...You guys cooking gear now?
Is someone know how to mording gear and shaft make one pice and sale to us? even all one pice plastic will be ok..no need matal shaft...
I think Losy can make this so easy better then send hole bad tranny parts
still face with you guys cooking gears...hihi :mrgreen:
Recall Toyo..Recall Losy....LoL

ahhh, it's all in good fun!!! and hey, why not try? the gears are either going in the garbage or maybe i can TRY to save them.... gonna try it saturday night...:mrgreen:

well keep us posted on how this works out...I've been meaning to try this & was going to set a flat plate on top of the gears as to help hold them flat till they cool down, i would think it should work???











ill take mine medium/rare:mrgreen:

i glanced at the topic of the thread and thought

Gears in Heaven.

its an old song, but sounds like where some of them may wind up.

so how long have you had them in the oven? I don't think the temp on an oven probably isn't accurate/stable enough. but, good luck...

I agree which is another reason to preheat the oven, turn it off then place the part inside on whatever you have to support it.

Everywhere I look I see people wanting to put things in their ovens? Gears, styrene, bicycle fork crown races. I like to put food in mine.

Did it work?

I think he finsh it with dinner..:mrgreen:

mmm roasted gear, yummy! did it work, was it tasty?

well i baked a gear this evening. pre-heated the oven to 450 and threw it on the center rack for an extra crispy crust... left it in for two minutes and the kept checking it every minute or so with a dental probe thing to see if she was getting soft. when it did i pulled it out and set it in the snow. after it cooled
it did indeed lay flatter...not perfect, but better. i dont have a shim gage set at home so i cant be specific. then i started looking at the gear and noticed that the gears are not cut as deep where it was warped as the rest of the gear.
hmmmm.....did i do that??? so i ripped the micro down and looked at the gear that was already in there. same thing. back to my baked gear. i took an exacto and carefully made the grooves deeper. now, theres no possible way i can achieve the proper pitch of the gear with an exacto knife. basically i just gave it more clearance.

so the verdict..the micro runs a LITTLE smoother. nothing to be wowed about. IMO, not worth the time. but ya know what? it's all in good fun!"thumbsup"

2 side notes..
the gear i baked was the bigger one inside the tranny.
also, i slabbed a little high temp grease on the steel plate to act as crisco.

oh and i am still running the gears that came with truck. the one i baked was a replacement sent HH sent me. when they arrived in the mail i threw them in in high hopes. turns out they were worse.

total bake time was around 6-8 minutes..baking time may vary!
