5216H differential

Recommended Posts

The differential on my 5216 started leaking a bit this year. It won't do it right after I cut but maybe a few days later after it sits. Not a lot - maybe a spot 2-3 inches long by 1 inch wide and then it stops. I top off fluid every month with gear oil. Must I replace the gasket and if so, is this a big job? Might it be one of those items you just watch and keep up with by adding a squirt of fluid each season? Tractor runs great otherwise. Thanks.

I am wondering if there is a breather on the differential. If there is and it is blocked up, the pressure will push grease out. I would also go over the bolts holding the halves together and make sure they are tight. I am assuming it is leaking at the seam where the two halves meet? Or is it out by the axle shafts? It is a pretty good sized job to remove the tranny and split it open, replace the gasket, and re-assemble and remount. I wouldn't do it unless the leak is really bothersome. Just my opinion.

Thanks Steve. It's leaking from the halves. I tightened the 3 bolts near the bottom half that I could easily reach but not much difference. I think I'll clean it up good the next time the deck is off and then park it on a large sheet of cardboard. I can live with adding an ounce or two each season.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
