127 no drive

[tservice]

I was cutting my grass and with no warning I lost all drive. There is no whining from the hydro unit. Where do I even check the fluid level? Thanks

tservice first off welcome to OCC. Should be a plug on the cover plate for the rear axle. That is the oil fill and oil level mark. If that is full I think the next thing I would check is where the driveshaft hooks to the adapter on the motor. Make sure the spirol pin is not broken.

Tservce:

I would be checking the Drive Line. I suspect you broke a Spirol Pin to one of the Couplers.

Thanks guys I will check that. btw on a 127 I know the 12 is the hp but what does the 7 mean?

[transformer]

The 7 means its a hydro even numbers are gear driven tractors and odd numbers are hydro's..

With the narrow frames, the 1xx was the way IH numbered the different hp tractors and series. As Transformer said, and there are some exceptions to that as well, the odd numbers were hydros and the even numbers gear. The exception to that was the 71 and 73, both 7 hp gear drives. This is the way the series and numbers work. The first two (or first number as in the 70, 71, 72, 73 and 86 tractors) are/is the hp. The third digit represents the series and whether it's a gear or hydro (see exception above for the 71 and 73). First series in this numbering system was the 100 and 70. Next was the 71/1x2/1x3 series. Next series was the 72/1x4/1x5 series, then the 73/1x6/1x7 series and finally the 86/1x8/1x9 which were wide frames.

1961-1963 - Original
1963-1965 - 70 and 100
1965-1967 - 71, 102, 122 and 123
1967-1969 - 72, 104, 105, 124, and 125
1969-1971 - 73, 106, 107, 126, 127, and later 147
1971-1974 - 86, 108, 109, 128, 129, 149 and later 169 (all wide frames).

I hope I got that right and it's understandable.

Thanks guys, Got it fixed. The collar had came apart. my have been designed to break away. I dont know But I welded it. As you can see I shimmed it, to keep it flush. Then welded on four sides.

I also would suspect a pin.

There are only two pins between the engine and the transmission on your 127.

The front one in the adapter is a solid pin and the one in the input shaft on the transmission is a spiral pin.

Glad you got it fixed. That should hold for a while.

Looks like I was a little late with my last post.

Never seen one break like that before...
