The Kia KM250

Cool video, thanks for sharing! I'm curious about the specs on the drivetrain. Top speed? Able to pull itself up hills? Is it loaded with sensors and electronics?

I'm more into the history of the original trucks. But it is interesting to see what new companies are doing with the design.

I can't find the KM250's axle specs.
They say max engine rpm is 2900, and top speed is 95 km/h. That's 59 mph.
M35A2 at 2500 rpm/.79 overdrive/6.72 ratio/9.00-20 top speed is 57.3 mph

 

[Rob01]

An M35A2 with the 4.90 aftermarket ring/pinion would run 78.6 mph at 2500 with 9.00-20 tires (40.9" height). That's unworkable.

A ratio around 5.90 (65mph @ 2500), in lieu of 6.72 (57.3mph @ 2500), might suffice with that 140 horsepower. Acceptable "startability" must be maintained.

Now there is a KIA I would buy.

Kia has been building licensed USA 2.5-ton and 5-ton trucks for awhile. I believe they're all still manual transmission but with a modern diesel instead of a multifuel. I'm wondering if they all have split-circuit brakes or full air brakes.

I believe there was chatter in the 5-ton board about using the dog bones and bushings off the Kia trucks as they're an improved design over what was original equipment in the USA.

EDIT: Actually watched the video now - I see they're still air-hydraulic brakes. That music though

Interesting tail lights. I guess Korea requires separate amber turn signals like several European countries do?

Yes, these are Kia's I wouldn't at all mind having, their M715 developments are nice too.

Cheers

Looks like quite a few upgrades on those compared to our old girls.

I love how they advertise that air over hydraulic brake system like it is brand new tech!

I would have to go back and watch the video again but it looked like the brake system used a standard treadle valve. Interesting…

the vid stated 183 hp. I also noticed the transmission shift pattern is the same.

Check out my thread in the hot rodding section "Modern Air Over Hydraulic Brakes". While the thread got a bit overtaken with other peoples different types of project, suffice it to say its totally possible to build a treadle operated air booster to run a split master or even multiple single masters. I linked to a company that builds and sells a kit, or you can build your own from NAPA, eliminating the air pack among other things. Also, take note that there was at least one motorhome company building class A busses well into the 90's with multiple air over hydraulic actuators.

I actually did read your thread not too long ago. Very interesting. That's why the treadle valve caught my eye on the newer version.
