I've been working on ol' Smokey, it's been a slow process. I got the "new" lower radiator housing and it's generally in good shape but not without a problem. It seems the PO wad issues with the coolant drain plug as well, the head was rounded off. I squared it up so I could get a bite with a 3/8" square socket. I twisted the nub right off
even with heat and Blaster, to no avail I tried to spin it out with a blunt chisel, stuck solid. I thought -
, I really didn't want to drill it out, but that's what I ended up doing. I had to drill it out to nearly the size of the tap drill size before it budged.
- Wheew! Got it, threads in tact!
To repeat myself from an earlier post... This all started out because I needed to replace the radiator on my Cub. A number of months ago I found and ordered a new radiator, made in Ireland, and looks real nice for $180.00. I took the hood off ond proceeded to drain the radiator (I haven't done that since I've had the tractor) and found a chunk of wood jambed into the drain hole with a bunch of sealer gobbed around it! The casting was broken out where the plug should screw in. Up to that point I thought it was just covered in grease and grime. Upon further inspection, the top of the housing had a bunch of braze and filler as well as a number of hairline cracks where the radiator bolts on. I attemped to clean the brass off to get an idea of how bad it really was, I ended up with a few pieces of the casting in my hand. To my amazement that particular area never leaked.
- The original housing with the wood plug and the "sealer" cleaned off.
- This is just plain ugly!..and didn't leak! ... before I cleaned off the braze
The area around the shiny spot had several hairline cracks which were brazed and liquid weld as a filler.
The new casting is from a newer Cub and has the reinforcing rib behind the tank.
- reinforced casting 350886-R2
- original casting 350886-R1
I scrounged up a 3/8" brass plug so hopefully the next time I won't have these issues.
- ...and I think I'll used neverseize on this one!
Now I'm on to replacing the front seal with a speedy sleeve.
