How to fix drain protector

[COS80]

I just discovered that my rear axle drain plug got unscrewed, presumably on Tin Cup Pass last weekend. I'm grateful that it only lost 7 oz. of fluid. The protective ring has taken several hits, and it clearly needs to be replaced, but how? Torch off, weld in pipe?

I don't know the diameter offhand and I'm way too lazy right now to go outside with a pair of calipers, but... if you could find a piece of pipe or tube that's ID is close to the OD of the original ring, why not double up? New ring around old ring.

Good idea. It is something like 1 7/8" OD. I'm not confident in that, but my neck's shot for today.

When you do this repair you might want to think about ordering some factory Toyota Allen head drain plugs from Kurt at CRUISERTEQ.COM that sit a little lower in that ring then the old style hex plugs do, plus they come with a Magnet. At only $6.25 a piece that's a hell of a deal.

Good tip, thanks.

Anyone know what the Toyota p/n is? I'll be placing a parts order soon, and I could just add it to that.

It looks like you could use some weld on differential armor. You could weld on a double layer of 1/4” thick plate around the area of the drain plug essentially forming a skid ramp around the plug with would be recessed nicely. I did this on my 80 probably ten years ago. Since that time I’ve ground them down built it back up with weld deposits.

That's actually a really good idea. Did you make yours from scratch or did you use one of the prefab/weld-on kits?

I used the nose bash plate for the front diff from Rough Stuff. And made my own
concotion for the under side. Same for the rear.
