we have an old HD16a (lol they are all old..) anyway when we bought it I talked to the owner who had it before the guy we got it from. He told me about a screen/filter under the seat (access from bottom) that you need to clean for the hydraulics for the brakes. Some times when I push the brake peddle to steer its like pushing a car brake peddle, just like butter, but other times it is like the flinstones and I feel like I have to push through the floor board and it really doesn't work., Ive checked the fluid in both hydraulic reservoirs and we replaced one of the pumps. Does anyone have a pic of this elusive screen? I've looked numerous times to no avail... |

i have a 16A. there is no screen unless someone added it. in fact there is no filter of any kind on the early tractors, later ones had a filter on each pressure line coming off the pump. there is only 1 reservoir and its in the engine compartment. mine is 4715 a '58, one of the last ones before the change to hyd wet brakes. you can look at the parts book here for 16A. A is 6 speed manual trans. some later ones had a pump on trans for oil pressure but that doesnt affect brakes. perhaps you have a later model? http://www.minnpar.com/partbooks/CRAWLER%20AND%20WHEEL%20DOZER%20MANUALS/ALLIS%20CHALMERS%20,%20FIATALLIS%20CRAWLER%20DOZER%20MANUALS/HD16%20PM%20%2370644082.PDF" rel="nofollow - http://www.minnpar.com/partbooks/CRAWLER%20AND%20WHEEL%20DOZER%20MANUALS/ALLIS%20CHALMERS%20,%20FIATALLIS%20CRAWLER%20DOZER%20MANUALS/HD16%20PM%20%2370644082.PDF ------------- Me -C,U,UC,WC,WD45,190XT,TL-12,145T,HD6G,HD16,HD20 Dad- WD, D17D, D19D, RT100A, 7020, 7080,7580, 2-8550's, 2-S77, HD15 |

that pump that drives of crank with reservoir in grill is for blade control ------------- Me -C,U,UC,WC,WD45,190XT,TL-12,145T,HD6G,HD16,HD20 Dad- WD, D17D, D19D, RT100A, 7020, 7080,7580, 2-8550's, 2-S77, HD15 |

Well, he told me there was a screen and when he cleaned it the dozer braked/turned that much better. I was really hoping it was true !! Lol |

I know this post is old however I have just taken possession of a 61 HD16DA. Hydraulic blade. My steering with just the hand levels and moving without a load like moving from one place to the other in the field, is almost non existent. I have to use the brake pedal with the steering lever to make any adjustments while moving. I have not tried with a load yet as I just got the dozer this past Saturday delivered and am adjusting tracks and fluid levels and grease first. Did you ever find out any more on your steering clutches? |
