Author Topic:   Removing Welded Spiders
posted April 13, 2003 12:05 PM
The 10 bolt rearend that I'm running is geared too high for my track and I'm needing to change the gear. My problem is that the spider gears have been welded together and there's enough welds slopped onto the spiders that they look and feel like they're going to be impossible to get out.

I have very little (if any) knowledge of rearends, but can anyone provide some insight to me as to how you get those critters out? I will be going back with a mini-spool with the new ring and pinion, that is if I ever get the thing apart to begin with.

If I understand your situation right, you don't need to remove the spiders to change the gears. Remove the axles and then remove the carrier. Change the pinion gear and the ring gear and replace. The new gears must be shimmed properly to work. A kit with gasket, pinion shims and new bearings is available fron National Drivetrain. Use a torque wrench to remove the carrier bearing caps and the ring gear bolts. Using the same torque to replace will be very close. Article coming in Stock Car Racing about installing a mini-spool.

Thanks a bunch Sleepy. Like I said, I don't know much about this area of the car, so your input is appreciated.

Also keep in mind most ring gear bolts use left handed threads.

I'm sorry if this is a stupid question but how do you remove/replace the axles?

Rico, thanks for the heads up on that one.

Hutch, it's not a stupid question. Remove the rear cover, draining the lube in the process. At the center of the carrier there is a pin (roughly 1/2" in diameter and 3-4" long) which needs to be slid out but there is a bolt on one side of the carrier, again near the center of it, which needs to be removed first as it is what holds the pin in place from sliding out.

Once the pin is out then you can slide each axle in, 1 at a time, to allow access to the C-clip. Remove the c-clip being careful not to drop it in there and then the axle slides right out.

If youve welded the spiders, think of your carrier as a full spool!! If you need to change gears that not a problem. Do as sleepy sugested.. good catch on the Left hand threads, I usually only remmber when Im about to put the socket on the big L on the top of the bolt head looks at me!!

Before you go arm crazy on that little bolt. The center pin retaining bolt.. Take the time to get a 6-point 5/16 box wrench or a six point 1/4 drive 5/16 with an extension to clear the carrier. I like the box wrench beacuse with the extension required to clear the carrier you loose all feel for torque.. Dont be tempted to use the socket at an angle. It may work once and a while, but that one time it'll round the head off or break, youll wish you had taken the extra min. to do it right. If its been apart recently, it will come right loose, and use some locktite when putting it back together, just some of the red i think it is. NoT the super duty stuff, the lighter stuff you can get apart later on.
Take that little bolt out and the big center pin will slide out..

what size rear end is it and what gear do you need might be alot easier to just find a used set up and slap her in save alot of time and head ache

I recently found that my rear was welded also. I opted to purchase a new rearend at pick-n-pull. I could not figure out how to remove the gear set(no way to drop the c clips on the axles due to the over zeleous welding). I then decided I needed a lower gear and I found out that the 308 and higher gear is a type 2 carrier and a 308 and lower gear uses a type 3 carrier. TO make a long story short, I bought a type 2 carrier, then purchased a 342 set with type 3 carrier on ebay. This has cost me extra dollars and time and effort. Make sure you get a rearend with a type 3 carrier in it if you are going to put lower gears in it. It will be cheaper for you in the long run.(and less headaches) I actually tried to install my gear set this past Saturday and found that the 342 pinion bearing is shaped differently than my stock bearing so now I had to purchase a new bearing which has cost me an additional 25 big ones.
This racing hobby gets expensive.

Unless it was just a stupid mistake,that may have been done on purpose sometimes the pin bore will get sloppy and it will break the pin bolt so the only way to remedy it is to weld in the pin.
