The insides of the governor can pull out of the case, keep them in the case if you can so the bearing doesn't fall off. Then remove the 2 bolts that hold the governor on the engine. Then the shaft assembly will pull out of the governor. You need to remove the governor to do that.īelow is a page from the Baler parts manual, showing the governor and connections.įirst you need to remove the throttle rod from the top of the governor, then the pin number 3 in the parts pic, and the 2 bolts that hold number 5 onto the engine.
You need to change the mesh of the governor gear, with the idler gear. TM Tractor at the bottom of the page has a new governor gear oil seal. If you have to remove the governor to change the gear teeth position, if the oil seal at the drive leaks, you could replace it while you have the governor off. The mark on the idler gear is on the side of the gear facing the rear, you see it looking in from the rear, like the 1st pic is, but after removing the governor. The 3rd pic shows timing mark on the idler gear, it drives the governor gear. The 2nd pic shows the timing mark on the governor gear, it is at the left in the pic. They should be aligned when the engine is at number 1 cylinder TDC. Sometimes people have the engine apart, or the governor off, and don't align the gear teeth right. The drive is made on the governor drive gear. If the drive is turned to another position, you probably won't be able to time the magneto correctly. The 1st pic below shows how the magneto drive should be turned when the engine is at number 1 cylinder TDC. Part of this info is the same as Jim posted above. If you can't get the timing to adjust correctly, it could have this problem below.
