Title: Where to find gears
Post by: JGRacing on July 25, 2007, 12:40:38 pm
I am pretty new to Legends (do not even have a car yet), but wanted to know what Toyota vehicles I can find gears and carriers in for Legends cars.  Can they be pulled from the correct vehicle in a junkyard, cleaned up, maybe put new bearings in, and weld the spider gears, or is it more complicated than that?  I am changing over to Legends for next season, but wanted to start keeping an eye out for parts to start stocking up.   I know that I can buy from parts dealers or on Ebay, but wanted to know what to look for if I come across something at the junkyard.

10 bolt Toyota rear end parts can be had from the wrecking yards.
Try these:

1974-79     Corolla     SR5 w/5 speed
1984-87     Corolla     GT-S
1971-85     Celica        ST,GT
1971-73     Carina     
1970-71     Corona     4 door
1972            Corona
1973-74     Corona     HT Sedan
1975-82     Corona     


Info is from "Dwarf Car Technology" by Steve Smith.
Hope this helps

Good Luck

Steve

You might want to look into buying a spool instead of welding the spider gears. It will make for a more reliable package. You'll also need to figure out what gear ratio you will need. I'll try to find the color codes for you and post them.

Try this link:
http://p206.ezboard.com/fdcrmessageboardfrm1.showMessage?topicID=4974.topic&index=1

You will only be interested in the 10 bolt. The pinion nut will usually be painted a color. This should help identify the gears if they are still installed in the car.

Hope that helps

Thanks for all of the information.  I appreciate it. 

Will the gear out of all of these 10 bolts work, or do I need to worry about the number of splines like with a Ford 9"?  Anything else I need to look for (ring gear size, bolt pattern, etc.)?

If anyone is looking for specific gears at the boneyard - look for a
'76 to '81 Toyota Celica. Look on the engine side of the firewall for
a 2"x3" metal plate with codes as per the following table - only pull
the driveshaft off to look at the pinion nut paint color to confirm
that's what you really want. The only way the codes are wrong is if
someone swapped the rear end out for a differnet ratio. Most
everything you'll find seems to be the 358's, though I've found a 342
and a 373.

T412 is a 330 - orange pinion nut
T382 is a 342 - purple
T372 is a 358 - pink
T302 is a 373 - red
T312 is a 390 - yellow
T292 is a 410 - green
T282 is a 430 - blue




 
330 celica liftback
342 earlier corollas
390 " "
358
410 earlier corollas
430 later models of both with overhead cams

How To Read The ID Plate:

 On the tag, there is a code number which is the very bottom line. It may be something like:
147FT11T052W55 (example)
In those numbers, the group that is "T052" in the example identify the ring gear diameter and gear ratio. The digit "T" identifies it is a 6.7" diameter ring gear (10 bolt). An "S" code denotes a 6.38" ring gear (8 bolt). You will want the "T" code.
 The second and third  digits of this group - 05 in this example - identify the gear ratio. the list below are the most commonly used:

 Code          Gear Ratio
   02               3.36
   05               3.70
   07               3.90
   08               4.11
   27               3.36
   28               4.30
   29               4.10
   30               3.727
   37               3.583
   38               3.417

 The fourth digit - in the example a "2"- designates the number of pinion gears and whether the rear end is limited slip or open traction type. The possible codes are:

Code          # of Pin. Gears          Ltd. Slip (yes/no)
  2                    2                                    no
  3                    2                                    yes
  4                    4                                    no
  5                    4                                    yes

  So, in the above example, "T052" designates that this car has a 6.7" ring gear with a 3.70 gear ratio and has 2 pinion gears and is an open traction type of rear end.

( Great book by the way!!!  Unfortunately, some of the adjustments, etc... are limited by the Legends Car rulebook.)

 Between what elimn8u_43 and I have listed, that should be the info you need.
 
 Good Hunting

Thanks again for all of the help.  I'll also have to pick up a copy of that Steve Smith book.

Where can you get spools from? ANyone ?
Title: Re: Where to find gears
Post by: justfreaky on September 26, 2007, 02:41:16 am
 $160 from 600 Racing.
I've seen some on eBay for around $165. With the season winding down, you might be able to find a used one. Post a wanted ad on this site, Check the for sale ads, auctions.
 Sorry, don't have any more info than that right now.

Guys I have a gear (paint on the end is white) I was told this is a 3.42 can I count the gears and confirm this???????If so how do I do this??

                                           THX Todd

Divide the number of ring gear teeth by the number of pinion teeth.

Thanks I will do that     Todd

So if you buy gears from a wrecking yard, do you have to weld them?
Title: Re: Where to find gears
Post by: thunder938 on March 23, 2008, 04:08:14 pm
Yes, or put a spool in then.  THe junk yard gears should be a posi or an open gear ( one wheel spin ) For racing the gears need to be tied together with a spool or welded..
Title: Re: Where to find gears
Post by: RickyBobby on March 23, 2008, 09:27:47 pm
Now is that an INEX rule?  Cause having the spiders turn freely would make the car turn better.
Title: Re: Where to find gears
Post by: thunder938 on March 23, 2008, 09:41:18 pm
rule book states

"the rearend must be locked(all spider gears welded or steel spool..). No  limited slip differentials, aftermarket differentials, quick change, floaters, homemade or otherwise are permitted.."

I think that about covers it,

RB,

 If you are running circle track you want to have the rear end locked.
You can use stagger of the rear wheels to aide in cornering.
 If you are running autocross........ I have heard that the open rear end or posi rear end may be helpful.
So far, I am still leaning towards the spooled rear end for my car.

Post by: RickyBobby on March 24, 2008, 09:26:57 am
why do you "want" to have the rear end locked.  Going around a circle causes one wheel to turn faster than the other. If it is locked then one will loose grip before the other.
Title: Re: Where to find gears
Post by: VMS Motorsports on March 24, 2008, 10:13:23 am
So you have power to both rear wheels, otherwise (especially on dirt) you just have one wheel pushing the car
Title: Re: Where to find gears
Post by: RickyBobby on March 24, 2008, 10:53:46 am
Dirt makes absolute sense and you guys are loose anyways :)
Title: Re: Where to find gears
Post by: justfreaky on March 24, 2008, 12:52:09 pm
It mostly has to do with getting the most power to the ground.
When a car is turning, the outside of the car is supporting most of the weight. (Weight Transfer)
This means, in effect, that there is less traction available to the driving wheel on the inside of the car.
Without limited-slip, or in our case, a locked rear end; you soon reach a point where all the power you are applying is being used to spin the inside tire, not to accelerate you down the track.  :o

There are some other things, but that is the most important part.

Does that help  ???

Break an axle and you will know why the rear ends are locked ;). If you break the outside axle the car will burn the inside tire off all the way around the track. If you break the inside axle you will  spin out coming off the corner so fast that you will not know what happened.
