Found out why my new to me 185 didn't stop very well...  Also wondering if the drum is supposed to be flared at one end...  Final question: Does the transmission oil need to be drained to remove the differential bearing carrier? I loosened off one of the bottom bolts and I saw oil coming out of it.  ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| Pretty sure the oil level is higher than bottom of carrier brg. |

| That brake drum looks shot to me...I can see what looks to be a taper in it. I have a set of relined brake bands with the good material on it, if interested and I can even get the disc brake drums as well, along with all of the springs, etc.. Send me a message, if interested. Rick |

Yeah, looks like brakes were a long time coming! that brake drum is shot, I would find a different one if it were mine. You will need to drain a couple gallons from the transmission/differential to remove the bearing carrier. When full, the oil level is just below the seal but high enough so the bottom of the differential bearing runs in oil. ------------- www.awtractor.com A&W TRACTOR 920-598-1287 KEEPING ALLIS-CHALMERS IN THE FIELDS THROUGH THE 21ST CENTURY |

If that's how the drums and shoes look, I'd imagine the rest of the brake system is equally worn. The disks would have to be worn too and the same for the steel they rub against. |

better get a service manual and check the inner to outer dimensions. IF two wide they will have to be machined and shimmed - or at least shimmed. IF they are worn like suspected your brakes will lock up when applied when reassembled unless fixed. ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

Yes, I do have a copy of the brake replacement procedure from the Allis service manual, courtesy of my local former Allis dealer. I used it a few years ago when I did the brakes on my D17IV. I did have to buy shims that time. I am more concerned about the shape of the brake drum seen above in my current situation. Do you think a machine shop can put them on a lathe to flatten that tapered ledge? ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

The diameter will be too small once you machine that drum. I looks like it's time to bite the bullet and replace some parts. Thank the previous owners for neglecting the brakes for years. |

This is the biggest problem with the tractor. I am not complaining. She will stop on a dime and give back some change by the time I am done with it. I see new drums are available, so I will add 2 of them to my list. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

So I got new brake drums and shoes from A&I. The original balls looked to be in good shape - no pitting or noticeable flat spots, so I put the assembly together with them. The Allis manual states that clearance between the drum and bearing carrier should be between 33 and 88 thou (I do not have the book with me as I type this) when everything is back together. But I am barely getting 15 thou with no shims on the bearing carrier. Anyone else have this problem? Had no problems when I did my D17 diesel a few years ago. Can anyone shed some light on how to get at least 33 thou clearance? Can the bearing carrier be machined down? ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| You don't change the shims on bearing carrier. Change shims behind brake surface on axle housing. Three bolts. MACK |

Since you said there are no shims behind the bearing carrier, if you removed them you could have problems in the future because they maintain the tolerance for the differential bearings. If you removed some shims there, put them back and use the shims behind the brake surface on the axle housing to adjust the clearance. As a last resort, brake surface on the axle housing can be machined down, but unless the A&I parts are thicker than the originals, you shouln't need to take that drastic of a step. ------------- www.awtractor.com A&W TRACTOR 920-598-1287 KEEPING ALLIS-CHALMERS IN THE FIELDS THROUGH THE 21ST CENTURY |

I had someone purchase a set of brakes from me for a D15 here a while back and he complained that the material was too thick. So, I sent him another set to try and he said they were the same way. I told him the material is and should be 3/16". He bought another set from A&I and said they were too thick as well, but matched the thickness of the ones I sent him. He said he got the drums from A&I and I told him to call an AGCO dealer or A&I and ask them what the diameter of the brake drum should be and that was the problem...the brake drum was to large on the OD and once machined down, worked great with what I sent him. NEW parts are not always correct. This might help to check that out...Rick |
