Roy Posted November 1, 2003 Posted November 1, 2003 The steering sector gear is loose on the shaft. The parts book does not show a key or keyway. Is the gear splined onto the shaft? If not splined, then what fixes the gear to the shaft? The gear moves about 1/4 turn on the shaft with the retaining nut tight. Thanks,
SmilinSam Posted November 1, 2003 Posted November 1, 2003 My book shows a woodruff key and woodruff key way cut into the the shaft.
Roy Posted November 1, 2003 Author Posted November 1, 2003 Sam, I'm talking about item 44 Steering Gear-to-item 45 Bevel Gear. My parts book does not show anything to lock them in place relative to each other. It does show a Woodruff key in the steering shaft to the pinion gear. Any other ideas? Thanks,
fuzy Posted November 1, 2003 Posted November 1, 2003 I tried looking up several different breakdowns and none show a key. But it looks like both parts have some machining done for a key. possibly they forgot it on the breakdowns. The newer 7100 series looked like it was a double d cut shaft. Hope this helps. John
Dutch Posted November 2, 2003 Posted November 2, 2003 Roy, Remove the nut and washer and inspect the end of the shaft. You should be able to see if it is round with a keyway or double D cut (rectangular hole). If you have to remove the steering assembly and plan on keeping the tractor, I would suggest you replace the needle bearings and drill & tap the steering housing and steering shaft bushing and install a grease fitting.
SmilinSam Posted November 2, 2003 Posted November 2, 2003 I don't have the 7000 series parts manual, so my numbers don't match yours, but I have the 3400 series and the 700 series AC as well as the 7100 series Simplicity and it looks like the 3400 and 7000 series used a woodruff key to hold those parts tugether with a nut on the end of the shaft. My manuals for the 3400 Simplicity and 700 AC series clearly show the woodruff key and groove. The 7100 series looks to have started using a Square sided conection ( or double D cut) to mate the two together.
Roy Posted November 2, 2003 Author Posted November 2, 2003 Gang, From the feel of the slop it makes sense that it is a key & keyway or a double-D. Will remove the nut per Dutch and see what is there. Neither my Operators Manual nor the Parts Manual show a key so the the gear and shaft could well be a singe or double-D. There is a grease fitting in the housing and it is shown in the Manuals. Thanks to all. Will keep you updated on my progress.
DaleC Posted November 2, 2003 Posted November 2, 2003 I have the D on my B-12 and it is also sloppy. If you figure out how to fix that, Let me know. I cannot for the life of me come up with a solution. I even thought about puting a shim in to try to take out the play. I had an old feeler guage set that I took one of the thinnest blades off of and tried to get it into the space on the D side. No go. If anyone comes up with a way to tighten it. GREAT!

The bushing for the steering shaft runs dry.
KenK Posted November 2, 2003 Posted November 2, 2003 For the slop in the B-12,I use shims in opposing corners.Cut them to fit,this has been working pretty well.I've been tempted to weld it solid ,but I have'nt gone that far yet.
Roy Posted November 2, 2003 Author Posted November 2, 2003 I took a look today per Dutch's suggestion. Fusy was correct. The shaft and gear are a double-D (round shaft with 2 flats). Since I am probably going to replace the dash/cowl piece I plan to wait until I have the dash off so I can get the steering assembly out. I think I can get the shaft welded and ground to repair it. Not sure about getting the sector gear repaired. It it is steel It can be welded and fixed. It it is cast iron I'm not sure about a fix unless it can be drilled and bushed to fit the shaft. Dutch, I'll put a grease fitting into the steering shaft bushing when I get into it. Thanks to everyone for the input.
SmilinSam Posted November 2, 2003 Posted November 2, 2003 Hmmmm... Wonder when the change from the key was made? My 700 series manual was dated late 1974 and my 7100 series manual was about 1980. Do you know what year your tractor is?
Roy Posted November 2, 2003 Author Posted November 2, 2003 Sam, I think it is a 75 or 76. Not sure though.
fuzy Posted November 2, 2003 Posted November 2, 2003 Roy, If you can't get either of them fixed the parts are still available new. They due run about $40 each. Drop me a line if you need either of them.
HubbardRA Posted November 3, 2003 Posted November 3, 2003 Roy, I have an extra frame with a complete steering assembly that I am not using currently. I'll trade even if you want. That way I could fix yours if I ever needed it. Mine is from a Homelite T13. Same as the 7013. I'll try to check it for play this evening. I think it is tight.
Roy Posted November 3, 2003 Author Posted November 3, 2003 Fuzy, Thanks for the info. Nice to know that if all else fails new parts are available. Rod, I may take you up on that deal but it will be a while before I get mine disassembled. When you look at it take the gear off the shaft. Make sure they are not worn and fit together tight. Also tighten the nut to make sure the gear does not bind the shaft to the housing. Thanks,
Roy Posted November 8, 2003 Author Posted November 8, 2003 Dutch, I take it that if I drill & tap the steering bushing for a grease fitting a 90° fitting should be used and pointed down so it can be accessed from beneath the tractor? I cannot see any other way to reach it once the battery & gas tank are installed. Thanks,
