  • TO 30 coollant question
  • Bought a Ferguson TO 30 last summer, moving snow the other day when the overflow tube on the side of the radiator started spitting out coolant. I had not added any coolant to to the tractor since last summer. I was told it could be the head gasket, so I removed all four spark plugs, tested each cylinder and all cylinders were around 75 psi. Question is: would one cylinder be low because compression is going into the cooling system? Thanks for any advise. Bob E

  • Could be a lot of things for overheating, loose fan belt, bad water pump, bad thermostat, head gasket or just clogged radiator. Check to see if you engine oil is clean or it looks like chocolate milk. the TO fergusons were notorious for cracks in the block in between the cylinder.

  • Kirk, I,too, have seen them cracked between #2 and #3 cyls all the way to the center main bng journal. An old, local machine shop here used to machine a long 1/2" grade 8 bolt down in the middle, drill holes in each side of the block, install the bolt with the sleeves out, then, re-install the sleeves with slight amount of clearance between the bolt and sleeves. Of course, they would cut the head off the bolt and machine thread both end, and tighten the nuts on both side to pull the crack back together and keep it from leaking. When I would buy a TO, I'd look at the block to see and see if this procedure had been performed. It worked quite well, Dennis.

  • Oil looks good, compression around 75 in all four cylinders, if there was a crack wouldn't compression be low in that cylinder? Thanks Bob

  • The sleeves have a lip on top that seals to the head gasket, so, compression is not effected---the crack happens in the block between the sleeves---you'll mostly end up with a small amount of water in the oil--a good indicator is to take off the oil filler cap and look for condensation under the cap--if it looks milky, not a good indication. The bad part about the crack, is that, no only is cracked between the cylinders, but all the way down, usually to the middle main. I've always chosen the Fords over the TOs because of the weak structure of the block, but they were a good running tractor when right.
