questions on my '41H

I"m just getting my 1941 H back together after doing a whole bunch of work on it (rear axle gaskets, new radiator, carb, belts, etc) and need some advice on a few items

1) the water pump seal where the shaft couples to the fan was replaced. It didn"t leak sitting stationary, but it drips a little bit when running. I need to crank down the nut, but getting to it is a real issue. Does anyone know what size wrench fits the nut? unless someone has a magic trick, I"m going to bend a cheap wrench to get there)

2) while running, the engine puffs blue smoke in bursts. it"ll be good for a few seconds, then poof, then everything settles down. I"ve never had an engine run like this. Blue smoke means oil, but I"m just dialing in the carb, so is it a related issue?

3) when I had the radiator cleaned, I also needed a new gasket for the cap but was told it was unavailable. So I made my own. However, I didn"t have a thick enough gasket when I fired up the tractor to seal the cap. Strangely, the water temp gauge never came up until after i shut the engine off, and even then the needle just started to climb into the bottom of the white arc. I ran the engine at power for over a half hour, keeping a handheld IR gun on the engine and cooling system and everything was very cool. There was also no boil off of the radiator coolant. If I add radiator cap gaskets in order to seal the cap tight, am I going the wrong way, or should I leave the system unpressurized?

The puffs are indeed oil and are not related to tweaking on the carb. Here are some things to check to see where you're getting the oil from. he first and easiest is the air cleaner. Pull the tube off at the carburetor and see if the air supply pipe is oily. Start the engine and watch the exhaust.

If it still puffs smoke, ground out one spark plug at a time to isolate which cylinder is the culprit.

Another place oil can get in the engine is through the valve stems. The intake and exhaust rocker arms are made differently. One will oil the stem (exhaust) and the other has a bevelled top edge so the oil will drip off the rocker before it can get on the stem. You will have to pull the valve cover to check this. It is possible you are getting an occasional drop of oil on an intake valve stem. Having recently assembled the engine makes this the most likely cause.

The last place it can get in the combustion chamber is past the rings. Normally, this causes the engine to smoke continuously. However, if the other areas have been checked, check the rings and make sure nothing is broken and that the gaps are staggered around the piston.

The water pump on my SMTA leaked also. I used packing from a Better Built liquid manure spreader. I put two winds in the pump and tightened it up. I then greased the pump and it quit leaking. Good luck.

1. You can try the nut, but you may also need new packing, available from Case-IH. I have had problems stopping mine from leaking, I seem to be the only one with this problem, packing should solve it. To tighten the nut, you need a 7/8 inch stubby wrench. If combination, use the open end. It is a tight fit but can be manipulated to work. 2. Blue smoke is oil, I don't have an answer for the puffs, though. 3. Your system is not pressurized, not on a 41 anyway, unless you have a replacement pressure radiator. The gasket is really not that important. If you wish you should be able to find a new cap -- it must be the non-pressurized one, the pressure cap will not fit your radiator. You can tell the difference between pressurized and non-pressurized radiators, by looking at the radiator neck. If the cap fits on the outside of the neck it is pressurized, if the lip the cap fits in is on the inside of the neck, it is not pressurized. You don't need to seal a non-pressurized radiator. If Case-IH doesn't have the cap, OEM Tractor Parts and others will. Your cold engine is the rule and not the exception, they warm up very slowly.

thanks for the advice - I figured as much on the wrench and went and bought the cheapest openb end wrenches I could find (10 pieces - $12) then started cutting them in half to have room to turn them. Thanks for the 7/8" - I had started out by cutting the 3/4" wrench. This will save me time.

After posting last night I noticved the existying radiator cap actually says 'fuel' on it under the paint, so I'll correct that problem
