Your fab work is impressive and this truck will be sweet.

Re: Ultimate work truck/ 70 K10 diesel
I swear I had good intentions..........
The crossbar on my transfer case had some play in it and I wanted to tighten it up. I took the crossbar out, and drilled out the holes in the shift rails for bigger pins. However, when I tried to drill out the crossbar, it is so hard it actually ground down my drill bit. So now, the holes in my shift rails are 3/8", and the crossbar holes are 5/16". So my options are to disassemble my transfer case and track down some other stock rails, or twin stick it. I'm leaning towards twin sticks. :metal: |

Re: Ultimate work truck/ 70 K10 diesel
I'm almost done with the shifters. I had it basically done, but i realized it was gonna hit the floor so I had to redesign it. I'll post some pics soon.

Re: Ultimate work truck/ 70 K10 diesel
Got some progress to report on my TC shifters. I set the cab back on to make sure of clearances.

I've been part timing at a fab shop with a waterjet. I drew these Dodge valve cover spacers on Autocad and cut them out of 1/4" aluminum. http://i447.photobucket.com/albums/q...216_140815.jpg Pretty cool what you can do with a waterjet. If anybody needs anything cut, PM me and I'll get you a quote. If I can draw it in Autocad, I can cut it. |
Re: Ultimate work truck/ 70 K10 diesel
I love the fab skills you got!
By the way... I just put one and one together and got 3500. I'm curious to see how long that NV3500 lasts. In 150K miles Mine was rebuilt twice... and that was behind a 350. The 3rd time it went out I replaced it with a NV4500. The 3500 did shift smooth though... |
Re: Ultimate work truck/ 70 K10 diesel
yeah we'll see. The 3500 cost me $150 and I like the gear spread better than the 4500. If the 3500 doesn't work out I would rather find a Tremec TKO than the 4500.

Re: Ultimate work truck/ 70 K10 diesel
I don't have any use for the super low 1st gear on a 4500. My BIL had a early 90's ford with a 7.3 and I'm assuming a zf5. It was a blast to drive. 1st gear was still a little low though, but it shifted fast and smooth. I've only ever driven the dodge version of the 4500, Is the chevy version different? The other thing I don't like about it is the LONG shift throws. On my brothers dodge, 1st gear would almost hit the dash, and second would almost reach the seat.:lol: The zf5 seemed to have pretty short throws.

Re: Ultimate work truck/ 70 K10 diesel
There are 4 different versions of the 4500. We will say there is a wide ratio and a close ratio... then there is the early shift tower version and the later shift tower version. chevy used the wide ratio 92-94 close ratio 95+ Dodge used the close ratio only. Chevy used the late style shift tower 95+ and Dodge went to the late style in 98. The later style 4500 works AWESOME behind a diesel if you use a high axle gear. 6BTs are awesome with the 4500 and 3.55s. The 6.5L with the 4500 is awesome with 3.42s for stock size tires and 3.73 for 33s and 35s.

Re: Ultimate work truck/ 70 K10 diesel
I did some research on the tko last night after I posted and I don't think it will work. First gear is a bit too high and the shift tower is too far back. Tremec also made a 4050. I wonder what its like. I think the gearing is similar to the 4500, but I wonder if its any smoother.
|
Re: Ultimate work truck/ 70 K10 diesel
For now I'm gonna run the 3500. If I ever need to replace it, What year 4500 should I look for? It would need to be a 2wd unit. If I can find a dodge one, can I put a gm bellhousing on it? And will the 3500 hydraulic clutch MC work?

Here is how to visually identify what you want to look for in the chevy NV4500 bellhousings 1992-95- have the housing on the lower passenger side for the external cylinder 1996+ has a large cut-out in the drivers side for the hose for the internal release NOTE: bellhousings are not interchangeable. Case to housing bolt pattern is different. top covers 1992-94 shift lever has the same style retainer as the SM465... round spring locked cam 1995+ shift lever housing is removable. It is square with 4 bolts. This top cover also solved the 3rd synchro failure problem. NOTE: top covers are interchangeable cases (bellhousing removed) 1992-95 input bearing retaining plate has a collar for the throw-out bearing to ride on. Use with external cylinder style bellhousing 1996+ input bearing retaining plate has NO collar for the throw-out bearing. Use with internal style bellhousing One more thing... you shouldn't have an issue with this since your t-case is further back, but when I was mocking the NV4500 up in my 70 (married 205) the driveshaft was VERY close to the boss on the bellhousing for the external cyl. how does yours look? The 3500 and 4500 release cylinder housings are identical. |
Re: Ultimate work truck/ 70 K10 diesel
Thanks JB. I'll keep my eyes open. My driveline has about a foot of clearance from the slave cylinder.

Re: Ultimate work truck/ 70 K10 diesel
Another thing on the diesel NV4500's whether GM or Dodge, is that the gearing is slightly different than the gas ones. I prefer the Dodge 98 up NV4500's.

Re: Ultimate work truck/ 70 K10 diesel
My dad has a 98 cummins dodge. Tranny seemed the same as my brothers 94. But I haven't driven either in quite a while. Can you shorten the shift throws on them? Thats the one thing I liked about the 6 speed. The shift pattern was smaller.
|
Re: Ultimate work truck/ 70 K10 diesel
95+ GM and 98+ Dodge there are short throw kits...

Re: Ultimate work truck/ 70 K10 diesel
Cool build! Looking forward to hearing it crank up!

Re: Ultimate work truck/ 70 K10 diesel
Pulled the motor and tranny, and was able to get a better shot of the TC linkage.
http://i447.photobucket.com/albums/q...229_153917.jpg Lately I've been working on the peddles and linkage for the brakes and clutch. http://i447.photobucket.com/albums/q...229_153853.jpg http://i447.photobucket.com/albums/q...229_153903.jpg I'm useing a hydroboost system from an 82 3/4T and the master cylinder that came with my tranny. http://i447.photobucket.com/albums/q...229_153840.jpg The hydroboost mounting was easy. I didn't have my camera with me when I did it, I'll try to take some pics when I take it back apart for paint. I also moved the pedals back about 3/4". Right now I'm working on the gas pedal. I picked up a pedal assembly from a 72 C10. I'll take some pics of that tomorrow. |
Re: Ultimate work truck/ 70 K10 diesel
Beautifull work,as usual! :mm:
|
Re: Ultimate work truck/ 70 K10 diesel
Great work. I was trying to decide where I was going to mount my MC for my clutch the other night too. Did the hydra boost just bolt right on? I hope so because I've got to put that on mine too. :lol:
|
Re: Ultimate work truck/ 70 K10 diesel
As far as the mounting, heres a picture.
http://i447.photobucket.com/albums/q...hydroboost.jpg As far as the linkage, you gotta figure out how long of a stroke the hydroboost needs, and measure how far the peddle arm moves at different heights until you find the right amount of movement. On mine, it ended up a little bit below the factory hole. My hydroboost came with the push rod, but it was a little short so I welded a small piece on the back of the peddle. For my clutch though, I made a new rod long enough to mount to the clutch peddle. With the clutch MC, I mounted it in the vertical rib on the firewall. I cut some 1" pieces of 1/2" OD tube and sleaved the bolt holes between the rib and the firewall. I'll try and get a better pic of that. |
Re: Ultimate work truck/ 70 K10 diesel
Thanks for the pic and info! I might run 92-97 ford mc on top of mine because the dodge ones are a poor design where they go into the cab. The ford mounts with 2 bolts similar to the chevy style. I'm glad the hydra boost isn't a big deal to install on there. One less big hurdle to over come. :lol:

Re: Ultimate work truck/ 70 K10 diesel
You might check into running a Chevy one. Might be easier.
