New here with a 653 :-)

Hello all, new member here cause i just picked up a nice little 653 a few weeks back.
I have been reading all i can around here ( i think i have read damn near everything back to page 42 so far...) but, hey its cold and ridiculously snowy outside so what else can i do. Its a good thing i grabbed it when i did, we just passed the 100 inches of snow mark so looking at the UC would have been real tough if i waited. Anyway, it runs well and is generally quite nice. Needs new brake bands as they are worn to nothing and as a result the steering clutches are also stuck. Not sure how bad, i guess new brakes and a workout to see. Its been sitting several years with periodic starts and a drive back and forth to keep everything moving. Its too bad the lack of brakes made keeping the clutches free impossible. I shall need to fix the track adjuster on the left side as well, it went out and they welded a shim in there to finish the job. The final seems to weep a little oil on that side as well, not a major leak but something i'll see about fixing. Need to get the service book and see how big a job that is. Overall a very nice little bugger at a price i can't complain about. Now if only the snow would leave so i can have this thing dropped off and start to get her ready for some fun time.

Hi albatross, this isn't my first time with steering clutches. I have a IH 500C tracked loader sitting in the driveway under a tarp because i didn't get the clutches back in before snow flew. Its about the same setup as the 653 and it was certainly fun as one of them was sitting in 6 inches of water. Those clutches are back together, just awaiting the thaw for reinstall. Well JC, i have certainly been giving my old JD 400 backhoe a heck of a workout on the banks. Have them piled about as far as i can go up and pushed as far back as one can on an old 2wd tractor. I will certainly say the old gal does a good job though. With the darned wind we seem to have constantly its a battle to stay outdoors very long. I think mother nature got our weather mixed up with someplace arctic... Oh, and thanks for the compliments, she really is a good looking unit. I shall share lots and lots more pics once she gets home.

Interesting, i have seen pics with 2 styles of cage. I'm just glad it has something on there. My current dozer is a T340 international and it has nothing. Thats finding a new home and this is the upgrade :-)

Nice looking machine, too bad it wasn't ready to go before the your area began to look like the Arctic.  I see it was in the 30's (above) in Fairbanks, AK today!   Good luck on your project and welcome to the forum!

One quick question while i wait for the service book to show up. Is the track adjuster rebuild procedure on these about the same as any small crawler? I (thankfully) haven't had to rebuild one yet but from reading on other small crawlers its pretty straightforward and cheap to accomplish. I'm hoping its the same case with these.

will this help

I would greatly appreciate it if you could send me the part # straight off the fuel injection pump on your 653 dozer. Mine is missing and the 7402-3200 pump # Allis Chalmers list does not help me with injection pump sites. Thank you and your dozer looks nice. I have  to get mine running before anything else, but I want to see it up and going.

My 653 won't be home till friday, just got the snow melted back far enough to have a place to put it. Then i'll gladly get you the info, the pump is a fresh rebuild and nice and clean so should be easy to read.

Just a FYI, looks like its going to be more like saturday before the machine gets home. Started a new job this week and its BUSY, putting in 10 hours a day at the moment and utterly worn out but happy i'm getting paid. Once its home i'll post that info.

Ok B52FXR another delay.... by the time i got it safely stowed away i didn't have time to remove the side covers someone was kind enough to make the dozer at some point in its history. I can see the injection pump but without pulling that cover can't see any numbers. Not sure if i will have the time to get over there monday or not, might be all the way till wed before that happens. For everyone else, i did drive it briefly to get it parked (not that its too adventurous when it won't steer) the brakes do still have some bite to them. Will seriously slow it down and make it labor a bit so those are not as toasty as i initially thought. The steering levers have almost no resistance whatsoever and that seems suspect. The plugs in the bottom of the clutch housings are in place so thats no good, a good indicator things are probably rusted up well in there. Fortunately i do have someplace i can pull it in and work under cover once i pull the cage off it. Then i can take some bits off and see what i find.

Thanks for being patient. For what its worth the guy i bought the dozer from had sent the pump out for rebuild several years back and remembered it being a roosa master pump just like the one on his case 580 backhoe. I know they make a lot of pumps and i'm sure they all look similar but if it really is the same as one for a case backhoe you should have an easy time finding one.

UPDATE ON MY 1975 ALLIS CHALMERS 653 Dozer.

I have her running..................... smokes like a freight train but she is running. I have to see if I need to time her...............or if I overlooked the crush washers in the head where the injectors are located. I was told that sometimes they are stuck down in the hole. Thank you all who have helped me with putting her together. More to come.
