Farmall Super M-TA Diesel Change Over Lever Adjustment: Not Locking In


Recommended Posts

Just picked up another M-TA Diesel and ran across the issue of the gas to diesel lever not locking into the gas position. The tractor will start on gas by holding the lever forward but will go straight to diesel when you let off. You can hear the over center snap but it doesn't set.

 

Any info on where to start would be appreciated.

On the right side of the engine is a latch pulled by a spring that "ratchets" into place to hold it in gas mode. The latch often gets sticky and needs lubricating, or the spring is broken. If there is enough slop in the linkage on the left side so as for the lever to not be able to push the mechanism far enough to latch in, it may just need adjusting.

Thanks for the help, spring was there but stretched. Ended up cutting and re bending the spring and it seems to be holding until I can get one ordered.
