Italeri Peterbilt 378 conversion


Recommended Posts

Ok guys here we go again, I have been encouraged to post this build...... suffice to say it has gone through a few changes, in the conversion thoughts. I have had this kit for quite a while, partly started, with a vision of a heavy haul unit, but it got put on the back burner for a few years, due to looking after the ageing parents, then a move , then just life getting in the way of good bench time..... so with all that behind me I decided it was time... but I changed my mind once again on the conversion. When I saw that Revell had reissued their Kenworth gravel truck, I thought, that is the way I should go, as I have almost 40 years of gravel truck experience it should be an ok conversion, IF I could secure a gravel box from that kit. ................. Ron G. to the rescue !!  He had a spare box from the kit in question and gave it to me... perfect ! Now, I have no excuses.....

This is the kit I started with.... and there will be some mods to the truck itself, but it comes with a 420 HP 60 Series Detroit and what appears to be a 15 or 18 speed transmission

So some of the mods will include the non-installation of the sleeper, High flotation tires ( and rims) for the front axle, aftermarket drive tires, some de-chroming of some bits, and the biggest thing, is a frame shortening, from a highway tractor to a gravel truck. Now, the frame had already been made, a long time ago, and it took a little brain work ( somewhat taxing for a non engineer LOL) :rolleyes:. It wasn't as easy as chopping off the back end of the frame, I had to or more wanted to keep the integrity of the rear part of the frame to correctly mount the rear ends and suspension, so it was to be the middle of the frame and so as not to foul any cross member, so with a little research, and a phone call to my buddy from work, I cut out about 3/4 of an inch in the center part of the frame and spliced it back together.... you will notice the plates are bolted and not 'welded'  .... so out came the Meng bolts ( those are really cool and I should get more)  Turns out, I measured straight and correctly, and managed to get the frame shortened and put back together straight and true. I was quite please with myself, as I had some trepidation :poo:on cutting up a VERY expensive kit. But all worked well....

The Detroit 60 Series is a good engine, and we had one in a Western Star at work, that I drove pulling a pup gravel trailer, for graveling and paving, I know some will say this is the wrong color, BUT the one in the truck I drove had a Red 60 Series....it wasn't the Detroit green... so mine is red.... the fit of these kits are wonderful overall, and not a huge amount of cleanup parts wise... I did de-chrome the valve cover as it was WAY too bright and as the real one was painted, so is mine....it fit well, I also added a few air lines to the transmission for the range changing valve, I added an inspection plate and bolts on the lower side as well a an oil drain bolt, plus the bolts for the top cover of the transmission.

I worked on the dash a bit, I scrapped off all the raised detail and replaced it with the EXCELLENT CTM photo etch parts, and added a little plastic rod on the brake valves on the dash to give it a more realistic look as in the real deal the spring brake valves are not flush to the dash, one has to get his fingers behind it to activate. I also added 'glass' to the gauges....

The dump box was built as per the instructions although I did modify the cab guard to more resemble what we have around here. Most of the guys have Nahanni dump boxes, made right here in British Columbia, and the cab guard has a bit of a rake to it, rather than what the kit had as dead level. The dump box is to represent a  Truckweld box, and has the Iconic Truckweld tail lights that stick out to the side...  I chose to change that to the oval recessed style that is so common locally. Again this is the CTM Photoetch, these are quite small and are made up of three pieces each, I personally think they look much better than the stock ones, these are what I am used to cleaning and fixing when needed.

And this is the basic mock up..... lots of details to be added yet, but this is the vision, still need front fender flares, battery box covers, clearance lights, mirrors, bumper etc etc.....  notice the de-chromed fuel tank, and the dechromed rear wheel hubs.... hope you guys like this vision....

Hey Jeff 

  She's looking real good. One thing though you didn't put in the dump control box inside.😉🙄 Were did you get the rear tires? And how well do they fit the Italeri rims?

Ron G 

LOL, oh but I did, just before it all went together...the tires came from our buddy Paul at ST Supply....the fit nicely but are just a hair too narrow, if you don't look too closely they are good....

Great build Jeff. Thanks for sharing this fantastic build with us. 

The BC plate is definitely a nice touch. 

Gee thanks Carl. Coming from you it means a lot. Happy you noticed the plate. It adds a little personal touch 😊 as mentioned this was a fun build.

Love it Jeff, your conversion worked out perfectly and the result speaks for itself. Like Peter, I learned a lot about American trucks, phew 18 gear transmission...
Always good to see something different here.

Cheers Rob

Thanks Rob. I appreciate that coming from you. Yeah the 18 speed is my favourite. I could go into details why but won’t bore you. A 5&4 ( two transmissions and two stick shifts ) were fun as well. It had 4 speeds in reverse ! Lol
