My 1979 175D needs a brake job, the linkage came loose on the left side and the right side will hardly stop it. Is this something I can do by myself? I am fairly mechanically inclined just haven't done brakes on a tractor before. I need to use some vacation so I figured I could try it and save some money instead of taking it to the shop. Also when I am in 4th High there is a low pitch whine, not noticeable going down hill, but pretty loud when under load or going up hill, any ideas what would cause it? Changed gear lube in finals drives last year, they seemed ok.
Thanks, Curt

Curt I think once you do one, the second one will be much easier...that said, when you get done come on out and do my 175D and D17 SIV Diesel.... ------------- ALLIS EXPRESS! This year: |

| It's a straight forward job you can do. Obviously you need some way of removing/inserting final drives, new linings,rivets,springs for the brake assy's. Be sure to get the clearance correct on the disc to facing contact point to be sure of good life for new brakes. |

The 170D that I am parting out had a whine like that....very annoying, but no clunking or grabbing....I'm thinking maybe a rough bearing as this tractor sat for 18 years before I bought it. It was kinda annoying driving it down the road.... ------------- ALLIS EXPRESS! This year: |

Could be just pitting on the final drive gears from little rust spots that form over the years from condensation inside the cases from heat-up in the day and cool down at nite...several of my tractors do that too and I don't think I have any bearings going out.

Here's a pic of what the final looks like when pulled apart.
and, the page is is from an I&T manual for a D17 s4, but should be the same for 175. Shows the important dimension "A"

| When I helped a neighbor get his brakes in his tractor, Ihad to machine off the inner and outter surfaces of brake faces to get them smooth again...which increased the the shims to where I took a sheet of steel and made a thick shim of 1/8th inch, maybe 3/16 and then added shims back in to make the 2.034-2.044 dimension. Not the ethical way but was cheaper than buying the two braking surfaces new... and that was 12 years ago and still workinggreat. Now his other brake needs work. So much wear was caused by a broken spring and allowed the brake assembly to rub |

| My God, you have to remove the whole wheel, axle and housing to change the brake pads??? |

Yes and all the hydraulic valves and fenders have to come off as well. Sounds worse than it is, but you do need a shop crane or some way to handle the final drives. ------------- Pullin With AC |

Ever do a brake job on a 4020? Of course they are wet and last a very long time like 7000 series Allis. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |
