| I almost bought a HD 15 several years ago, he said that he had switched the transmission and the transmission he put in came from a truck. I rode on the dozer and the machine ran and worked ok, but I missed the sale. I don't know it this is true but that is what he said. |

i dont see how he could have done that. the trans bolts to the bevel gear housing with a large flange and the pinion stays in the trans. not enough room in front between clutch and trans for another transmission. on a side note, if the tractors had been done this way, gear jump fixes would be a cinch. ------------- 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 |

So Roy, What were you looking for when you started this thread? We started with transmission comparisons and sizes. Are you working on one that we can help with? After that it seems like this thread went sideways quickly. BUTTT, just so everyone knows we can do that to. We did rescue an HD5 dozer once from some drugee kids that were about to fire up this HD5 that they had put a chevy 283 and 4 speed transmission in.  They had left the tractor transmission in and had just coupled the ujoint to the trany. We have removed the engine and other non AC parts since this became a donor tractor, thinking those chevy parts weren't applicable for AC donor parts. The transmission was left for conversation piece for now. (didn't know it really would be a discussion though).  So this is one of our sideways stories. The really really sad part of the story is there was nothing wrong with the 2-71 original engine!!. They had disassembled it far enough with the rocker cover off and left it out in the rain that it was pretty much scrap. We did recover all of that for donor parts if possible. Anyway, TRUE STORY! |

| I'll see Dan next couple of days and see if he has any parts left laying around. He isn't one to get rid of anything that might be useful in the future. I know he took the tranny out of a 15 with worn out motor and swapped it into the one I was interested in. |

| Roy, A lot of the farmers in the Sacramento Valley of Ca. liked there detroits too. A lot of HD16s had the 671s put back in them the first time the Buda/AC burped. It's not to hard to put that detroit in an HD16. |

| MEL IKNOW I,am changing the subject again but I wish at some time you would post a picture of all your tractors and even more a picture of your donor yard. I ENJOY PARTS TRACTORS AS MUCH AS BRAN NEW. |

I went looking for a parts HD5 25 miles from home a cousin knew about.Track where a crawler had been drug next to the pavement of the place tractor was to be.Followed a mile or so into another ranchett place. See a HD5 working and drive up,old boy comes over very proud of his 300 Ford with automatic transmission out of a 1/2 ton pickup in a dozer. Didn't get within a 100 feet of as they where pushing dirt,but could see and hear no Detroit in this one. Have no idea if it lasted more than the day,but was moving when we drove away. |

| Dose anyone know if it is possible to buy new tracks for a hd 15. I found a hd 15 in really nice shape but the tracks aren’t in the best condition. I’ve replaced undercarriages on dozers before so I understand the cost But I’m wanted to build a new old dozer |

| Those will be 7.850 pitch, unless find decent used no other in production machines use. Some have gone to CAT 8.0 rails with smaller bushing diameter but is pushing the realm of technology. |

| I wonder if a guy could buy new cat 8.0 rails that are the right length and buy some bolt on sprocket segments to fit the 8.0 rails and make a ring to weld on to the hd 15 sprocket to except the new sprocket segments ? A guy could probably call berco track and have rails made to any length. |

Going to be more than that to installing different chains though the idea is plausible. Remember, they have to stay on the tractor so need to fit the rollers and idlers for alignment. Anything can be done but in the end you'll have a lot of $$$ in a tractor you have limited ability to secure hard parts for if something breaks. Don't forget to factor in the wear and breakage from usage over time. Berco is not going to be easy to work with. Complete corporate mentality nowadays and not interested in the "on off" type sales as in days gone by. Alibaba is a better bet although questionable quality you will receive if ordering there. ------------- A career built on repairing and improving engineering design deficiencies, shortcomings, and failures over 50 years now. |

| I will more than likely do it. I’m really bad about refusing to let an old piece of equipment die and u are 100%right I will have a lot of money in it. But it’s a labor of love 😂. I will post lots of pics when I do it but the under carriage on it now has some life left |

Cutting the original sprocket down and welding a perimeter ring is actually a very good repair; have done similar in the past. But you need to be accurate or the tracks and u/c wear fast. Can't remember if Insley, or a Northwest crawler crane we were rebuilding the undercarriage on. Had a donor sprocket with good teeth, but incorrect center hub. Took the teeth off both sprockets, and put the good teeth on the needed hub center using a large lathe and face plate for the rotation tool. If doing it for yourself it can be justified. Attempting to sell that job nowadays would be a tough one for sure as there are a lot of hours wrapped into it. Hell, some of the filler rod that was used is now over $30.00 a pound for the build up material. Hard facing is every bit of that which would be needed also. ------------- A career built on repairing and improving engineering design deficiencies, shortcomings, and failures over 50 years now. |
