Haha thanks. Got the cleaned out gas tank mounted up with new filter housing. Also exercised my pet peeve by extracting two broken bolts left by a previous owner. Weld a washer to bolt then a nut to washer is the system I use. Works wonders.

Heh, that's funny - I have a couple of them warts in my radiator (and numerous other places too....). I'll definitely be using that technique. Do you drill the broken bolt first so it can shrink or do you find it reliable without having to drill?

Cheers,

Nope I dont drill. It may take two or 3 attempts breaking sections of the bolt but if you go slow bouncing the wrench by hand then it works almost every time. Of course there rarely is a bolt that takes drilling and threading to fix but its been rare. You can heat it up and use paraffin wax on the hot bolt to increase the rate of success but I almost never need to do either.

Vise grips and heat the part the bolt is threaded into with torch if there's enough bolt protruding to get a grip on........Welding on a nut if there's not enough sticking out to get a grip on. Heating the surrounding part is better than heating the bolt if you can do it. Sometimes you can't because of gaskets or the sheer mass of the part.

There's even special rods that you can supposedly start the weld on a broken bolt recessed in a hole and build it up to the surface and weld the nut to it there. I've never tried that, I hear the rods are very expensive, but the other ways of doing this are very time consuming as well

D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time:D

I used to just weld the nut on, but once I learned to weld the flat washer and then the nut it worked even better.Still takes more than once some time.Time is your friend let it cool completely before trying to remove it.

40+ years ago DuPont had a penetrating oil out that smelled like fine French perfume. It worked great, even penetrated uphill well. Broke off bolts were a breeze if you squirted it with some DuPont penetrating oil, hit it a few times, then welded on a washer & nut, then squirt and hit again. You could almost unscrew them with your fingers then. But it must have worked to good because the government deemed it was harmful to your health. Made DuPont recall unsold cans and take it off the market.

A friend got wind it was going to disappear and bought a case before the jobber got word to send it back. He guarded and used that stuff like it was liquid gold. I should have been so smart.

The smell gave me the impression that it had benzene in it. I suspected benzine because we had used model airplane racing fuel that had benzene in it.

The special rods I've used were called "X-Tractalloy" they worked ok, even horizontal, or getting out a tap.

Haha as I suspected you guys have dozens of ways to do it. Sad that the feds have to screw with our fun. Ill say for having only really worked on cars and trucks this machine has been a real pleasure to work on so far. Its to bad more things were not built with this level of quality and foresight. Got the oil filter housing all bolted up today after spending an hour chipping out petrified gaskets from them. I'm thinking ill tackle the water pump rebuild this weekend. Once that's bolted up its clean clean clean and paint.

I like the sediment bowl and tap that you have installed on the poney fuel tank. Is that new? I am considering sealing my fuel tank pretty soon but it does not have a sediment bowl and fuel tap on the tank, but I would like one. I only have the inline filter and tap on the starting side of the tractor (LHS).
I would like to know if the sediment bowl and tap is still available from Cat or is it an after market piece.
I have enjoyed this post very much. I am in the process of installing new crank bearings as well.
