After two years of restoreing my 43 allis i have two problems.After pulling the final drive housing away from the differential i have a small leak on one side.After pulling it carefully away i have tried different types of sealents to solve the problem but to no avail.Secondly i have a slight surge in the engine.I converted the six volt to twelve volt replacing the 6 volt gen. to 12 volt alt.added a 12 volt coil with a jumper lead to the mag.I timed every thing to TDC. and elimanated the 30 degree lag in the mag.Fuel problem has been ruled out as cause so has points,plugs and condensor.could it be something in the governor??? Thanks for any help.

The anti surge spring was removed from later engines as it did not seem to be needed. I have had some successes in levelling out mild surges by installing a spring. For big bogs look elsewhere (usually fuel). There should be a seal on the diff carrier that seals the pinion shaft from final drive lube, and I think there is one on the final drive that seals off bull gear lube.

My Model B had a surging problem until I found out that there was supposed to be an "anti-surge" spring on the governor linkage just in front of where the linkage hooks to the throttle lever. I found a little hole in the linkage. Looking in the parts catalog, I found a sping is supposed to hook there. It is the anti-surge spring. The AGCO dealer wanted $14.00 for the spring. I went to the hardware store and found a spring that is about 1/4 inch in diameter and about 2 1/2 - 3 inches long and of small gauge wire. It has hooks at both ends. I hooked one end in the little hole on the linkage and the other end to a maniforld stud and it works great. Cost = $.70. Just be sure you have the spring hooked to one of the front studs. I found out that it is not a throttle return spring, so it should not be hooked up to pull the throttle closed. It should put mild resistance on the linkage as it opens to prevent the throttle fron surging.

Good Luck!

James. where exactly is the oil leak at? Is it at final drive housing where it bolts to differential? If so it can only come from the oil seal at bull pinion shaft or maybe the bearing carrier containing the bearings at the differential. By the way, I don't think gaskets are required at final drive housing where connects at diff.

Sounds like the governor spring(s) are weak or possibly there is a bad bearing in it.

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S ... [Read Article]
