I am going to go look at a HD10 Allis Dozer setting on a estate sometime next week. To date I do not have any Allis dozers in the old iron line. I don't know anything about it other than it has a 4-71 Detroit that they say has been started. They have not tried to move it, said they have no clue how to run it. It has a double drum Letourneau CCU unit on the back with a cable dozer. Do these machine have Cat style steering clutches and brakes? Any info about them would be useful. I'll post pictures when I see it next week. Thanks, Roger
Yair . . . They were a real nice tractor, direct drive, over centre master clutch, conventional clutch and brake steering . . . like all Allis's on scraper work you could shift them on the fly. Letourneau winch can be a bear unless adjusted exactly right. They are simple though and only require standard bulk brake lining on the cones. Cheers.
Thanks for the info Scrub. It runs, been setting for a while. Are they prone steering clutches and brakes sticking like t.he old Cats were in wetter climates. How involved of a teardown is necessary to adjust or replace?
Yair . . . I can't help much really old-iron-habit. I just remember running one for a week or so finishing an earth tank for a bloke. It struck me then as a real nice tractor and never gave a moments trouble in the short time I was on it. I think they would be pretty standard construction with steering clutches and brakes out through the top. My memory of Allis dry clutch arse ends consists mostly of horrible oily/sooty black compartments, wired studs in the bevel gear and top pinion flanges and not much room to twist the wires when they went back together. I guess the technology was about the same as Cat so no doubt they could stick with time. The larger Allis's were a bit prone to develop wear or grooves on the inner teeth of the brake drum that sometimes could cause grief. Cheers.
One thing to check is the lube in the finals. These old Allis dozers used accordion seals and there haven't been any around in decades. I sold my HD10 back in the eighties and couldn't get any then. I just kept the level up and watched to make sure I wasn't getting any dirt or sand inside.
Thank you BillGfor the finals tip. I will check them for sure. it will probably get 4 hours a year in my stable so will check every time out if I decide to purchase it.
