Dana transaxle

Could someone help me out with this problem? I have a Craftsman model - 502.251220 with a Dana 4450-1 transaxle. My question is, how do you adjust the brakes. The brake rod comes back to the top (left) of the transaxle...there it has a threaded connector on it. I can adjust it both ways approximately 10 turns with no change in the brakes. The brakes are very "soft" in the way that they just barely stop the machine. What I was really concerned about was, the owners have a steep yard. Does anyone know of a web site where I might some information about it. I would like to know just what I'm adjusting.

Hello Jack B!

Look where the rod with the adjuster connects at the transaxle. It goes through a lever. That lever is connected to the tranny on a bracket. The bracket has 2 bolts, one on either end, and a nut in the middle where the lever pivots. Tighten this nut a couple of turns to tighten the brakes a bit.

On this same line

The same area cheese has you at, is where your brake pads will be housed. It sounds to me as though these should be replaced - lots of hills and all. As far as parts go, let your fingers do the walking and call around your area and ask if any OPE dealers stock parts for Dana tranny's.

Dana transaxle

After a bunch of searching, I finally found an exploded view and a parts list. After studying these for a while, I think I've got it figured out. The brake disc is on the drive shaft (the shaft with the shift keys). Then toward the back of the transaxle are the brake pads (all internal). Then there are a couple of vertical parallel wedges setting next to the brake pads. There is an adjustment bolt sticking out of the bottom of the transaxle at the back. There is a capture nut on the threaded shaft. Just a small adjustment made all the difference in the world.

An adjustment on the bottom of the tranny?? Is the diagram you found online? If so, can you give me a link to it? I'd like to see what this thing looks like. All the spicer (dana) transaxles I remember have an adjustment like I described. Most Peerless trannies do too.

Cheese,
The diagram was part of the owners manual, it's an exploded view and a parts list. They could'nt find the regular owners manual only these drawings. I have a new printer/scanner/fax machine and "whenever" I learn to use it, I will be sure and send you a copy.

If you go to the sears site http://www3.sears.com/ and use 4450-1 as the model#, you can access a IPL.
