  1. It might be worth the time pull the combine out of the divers is setting in. Not saying to drag it around the yard, get it on level surface and maybe it'll move and loosen things up. I had a 1440 like this one time and that's all I had to do. I was thinking maybe some of the pistons were stuck in a rotating group. Used it 3 more years before trading.

    1680 Duals

    Well that's sort of related to my overall questions. Is the purpose of the spacers just to adjust for row spacing? I don't do much row crop and what I have is 20 inch rows.

    Do I "Have" to use the spacers? If the inner wheel clears everything can I leave them off?

    1680 Duals

    I have a 1680 with 30.5 x 32 front tires. I know of a 1688 with 18.4 x 38 duals on it that I want trade tire setups with. Is it just as simple as removing and reinstalling? Is there more to it? I realize about ladder extension and all that, but is there more to it?
  5. There's not that many o-rings involved. There is 1 o-ring in the housing, it's at the front, where the linkage connects to the spool. There's another o-ring of the same size that is used on the rear end of the spool. There's an o-ring where the detent housing screws into the spool and then there's a small o-ring & backup ring that goes inside the detent housing around the release pin. So not many o-rings used. You will also need the "retaining" sleeve that is used to hold o-ring and backup ring in detent housing.
  6. Are you sure the oil leak ls coming from the top seal on the hand pump? My experience is that anytime I had one that leaked profusely when cold and almost quit when hot has always been the rubber sleeve at the bottom of the pump. Everything expands with heat and seals better.

    1066 oil flow

    I think you need to figure out where the noise is coming from. It's probably related to the oil pressure problem. Can you get an idea what part of the engine the noise is coming from? High-Low, Front-Back?

    1066 oil flow

    Well the thermostat change wouldn't have anything to do with it as long as it's operating correctly, but changing from 170 to 190?? Usually looking to go the other way. The "clacking" noise, have you determined where the noise is coming from? I'm concerned the "clacking" is a piston tapping the cylinder head because of a spun rod bearing.
  9. No, TA shifted with clutch engaged.

    1066 oil flow

    A couple questions. How did you realize this problem? Did the engine just get overhauled? Your not going to notice no oil at rocker arms without valve cover off. So as IHC_1470 suggested, it's probably a spun rear camshaft bearing. Or, if they were just replaced that bearing was not installed properly. There is a groove on the outer portion of that bearing that allows pressured oil to funnel up to the rocker arms through a head bolt hole. It's the only bearing of the 4 that have this groove, and it's OD is smaller than the rest, so it's not possible to get the wrong bearing in the bore. Is there possibly thread sealant on rear rocker arm head bolt? The oil galley in the block brings the oil in above the threads but thread sealant can still block off passage.
  11. What is this "color back"?
  12. I believe I misspoke saying the safety switch was on the engine. It's actually in the hydraulic system. Has to see hydraulic pressure in order to lower header. I think the switch is located by hydraulic filter.
  13. There is an oil pressure safety switch on the engine block. This switch has to sense engine oil pressure before it allows the header to be lower. So basically the engine has to be running in order to lower header. It's a safety thing so if someone bumps the switch with the header up, the header will not fall in case someone is under it. My guess is this switch is the problem. It heats up and cools down as the engine does.
  14. If you have trouble finding studs/washers/nuts from Case/IH dealer, go to International truck dealer. They will have or can get.
  15. Transmission in 5th, clutch in, no noise. You inch up on the clutch and the noise starts. This is long before the tractor starts to move. It's like when the hydraulic clutch pressure hits, this noise starts. Is pressure applied on the speed side of things before the master clutch engages? I would agree with missing tooth theory, just trying to understand why I hear it before tractor starts moving. I realize some gears are always spinning.
