Thats a later model 15B with the 407 engine, and the batteries are under the seat and the hyd control valves are under the cover he was talking about. I spent over 20,000 hrs operating 15 B& Cs in NZ back in the 70/ 80s ,good little dozers they were.
Hey mate , do yout homework .It is a two speed counter shift transmission with a manual shift Hi Lo tranny. Im an Aussie and spent several thousand hours on the C series. My late Father owned over 40 IH crawlers. From the TD18 As to the last of the TD25E Phase 3 Crawlers. My Dad made money out these iconic American machines.Look at your heritage and be pround. You are our mates
Just trying to document this before it went to the scrappers. It's probably made into rebar by now. So, I said in the video that I thought it was a 4 speed but I wasn't sure what that lever was (I've never run one). If I knew how to use a computer, I'd edit the video but if I knew how to use a computer I wouldn't be running equipment for a living.
I hate to differ with you but that track frame design had serious flaws, in the TD20 series c they were notorious for breaking the cross shaft upon which the track frames pivot. The square cap with the four bolts just in front of the sprocket is the cover plate to the end of the shaft. We replaced the cross shaft in my dad’s 20 twice, the second time we cut the shaft in two and made gusset plates thru which the shaft passed welded to the underbody, this seemed to help for a while, eventually the shaft end sheared off again.
That Dozer weighs more than 23,000 pounds it has four forward gears and for reverse gears and that is a high and low lever on the transmission there I'm by the floor you really don't know this Dozer
He is a bit off the mark there, thats a late model series B and has a DT 407 engine as well as hydraulic shift on the power shift and the later model track frames. The Hi-Lo lever gives the power shift transmission 2 extra speeds, in Lo range you have 1st & 3rd speed, pull it into Hi range and 1 st becomes 2nd and 3rd becomes 4 th. The machine had to be stopped to and in N to go from Lo to Hi. And the batteries are under the seat not where he said they were, thats the hyd control valves under the cover on the RH side. Good little machines they were, I spent over 20,000 hrs on 3 x TD 15s, 1x B identical to that one and 2x 15Cs, got all of them from new when I worked for a contractor in NZ back in the 60s> 90s, 2 had a PCU and the last one had rippers.
Why didn't you crank her up and work it a little. I wanted to hear that turbo whistle characteristic these machines had. This machine was more comparable to the D5 than the D6. D5s weigh about 27,000 lb and that is the approximate weight of this machine. D6s weighed about 35000 lb. This machine was revolutionary because it had an independent rear dead axle wich insulates final drives from many shock loads. All modern bulldozers use this design. Caterpillars continued on with the old design which pivoted the track frame on a dead axle that ran thru the final drive and that's why they had so many final drive problems. They also did not pin the front cross beam to the track frames and after many hours working in abrasive material the front cross member would push out on the track frame and result in premature failure of the main final drive roller bearing causing gear shelling and even cracking of the rear dead axle. This TD 15 was a great machine. Too bad IH couldn't keep on with it. They really had a great design but their engines and transmissions weren't as good as Cat. This was the probable cause of their demise along with poor management strategies.

The extra lever is a high -low range selector, so the Transmission is in fact a four speed.

The later 15 bees had a 407 International motor
Are you sure that is a dt 361? I thought mine was a dt 361. But mine dont have any filters on that side its got me wondering.

Just having another look at it and the LH track is on backwards.
It would eat a D-6 Cat alive.
