"Stubby" My 10 second Street/drag truck build

Yes...we work on powershifts and hydraulic transmissions here in the shop that are WAY more complicated. A stock or moderate build I would not hesitate to tear into one...but for the bigger power stuff, I would still tend to stick with my builder, as he builds hundreds each year to my 1 or 2 possibly. Just peace of mind, maybe a little misplaced, but still peace of mind.

Our powershifts have 6-9 sets of clutches, each up to 18 discs at about 9" diameter. Takes a special lifting device to even get the guts out of the case because of the way the gears and shafts fit together. They won't pass by each other individually, so have to come out as a unit.

Not mine, but very similar...half a transmission...

Sorry for the derail...

Not to derail the thread.....but I'm completely jealous, how does one learn to work on these transmissions? I only care about learning to how to work on my own 47RH's and have a donor trans. I bought a ATSG manual, but that didn't help, it's all still Chinese to me.

I agree with dan. I have my first trans back together besides the billet input. It's really not bad once you get it apart. Now i just need to see if it works......... that could be the deciding factor on building another one.

Well tracked down and bought back a pump I sold 8 years ago. It's a Columbus 12mm 913 based pump. 650cc, .120 holders, full cuts, 5ks, dual feed. It was off a puller I use to have was an awesome pump. Guy never used it.

Well the stuff in the oil pan was already fixed minus the random nut that definitely is not even from a Cummins. The KDP is still intact even though that is a KDP laying in the pan with aluminum pieces. Apparently the KDP fell out and destroyed the original gear housing. The gear housing on it now has a 210hp rating tag.
 
Makes me think someone didn't actually put bearing in this thing because that pan definitely hasn't been off in at least 10 years. I had to use a chisel to get the dirt and grime off half the pan bolts to actually get a socket on them it was that hard and caked on.

Sounds like all these old Baker Hughes QSK50s. 20,000 hours + 4 years of sitting out here practically abandoned. Fun stuff...

It was definitely off my man. The buddy that helped me is in love with anaerobic sealer. I am not but we were at his shop so I let him have at it. It is hell to get things apart and the oozy gooey left overs are just a dirt magnet.

The KDP explains the data plate I found in the glove box. He claimed they pulled the case because the seal behind the case was leaking. Obviously there was more to that. If they had the case off and i had the pan off how is the kdp in the pan? There is really nowhere for that to hide other than in the webbing of the case somewhere is there?
 
There was a PILE of aluminum pieces in the pan, the pin, the nut can't really hide anywhere but where I found it all in the bottom of the pan.
 
We drained the oil when the pan came off. We didn't wipe the pan out but it would have been very easy to see a pile of aluminum, nut, etc...

How did the dowel and nut not ever make its way to the magnet on the drain?
