ARAMP1's Ultimate TowRig Build Thread

I've got a little bit more done that I need to update. Standby.
 
I've had a couple people ask me how things are coming along and really the only word I can think of is "slow". I've been working a lot and when I do have any time off, I'm spending it with the boys. I'm able to work on the truck during the weekend when I'm not flying while the boys are napping in the afternoon and after they go to bed. The only problem is that I don't like working past 10PM unless it's pretty quiet. No air tools anyway.

I've decided to do away with the air starter. I think I might keep it and all the parts on the shelf for a while, but the air tanks just take up too much space. Originally, I really liked the idea of not having anything electrical on the truck, however it was quickly apparent that I would have to go with electric fans due to the lack of space for a mechanical fan. So no point in having a non electric starter and electric fans. I ended up buying this baby from Leid Diesel.

It's a lot smaller than the air starter for sure, but it's not as small as it looks in the picture. Just by looking at pictures, it looks like a honda starter, but it's still big. The only issue I see is that it's not adjustible and it may not fit between the block and the frame.

EDIT: Well, as I was afraid, the starter doesn't fit. I pulled off the air starter and here the two are side by side. The gear reduction one isn't too much smaller, but it's a lot heavier. As I loosened the bolts and dropped the Ingersoll Rand on my chest, it about knocked the wind out of me. It was easy to man-handle the gear reduction one into place.

Here the two are side by side.

Here's a shot of them from the underside. I wasn't able to tighten the top bolt of the electric one since the housing was hitting the blower, so it's not exactly perpendicular to the bellhousing.

And here's a shot of the side profile. It's mostly blocked by the frame rail, but you can see that the starter would hit the blower if it was tightened on. And, there's no way to even put it up to the bellhousing if it was re positioned to the other two positions. I was thinking that I might be able to grind a little bit out of the blower housing, but that may be more problems that it's worth.

Guess I'll call Timothy at Leid up and see what other options I have.

EDIT: Well, got the new starter in from Leid. Even though it's not a gear reduction one, it looks like it will fit for sure. (Of course the wife pointed out that I've said those famous last words before). But it really should. It's got an adjustable mount. And it should tuck up under the blower very nicely.

I got the starter mounted and it fits! I just wish it fit a little bit better. It's too tight to leave it like it is right now. The solenoid is only a mm or two away from the frame on top. You can see for some reason the frame creeps in and then back out. I can probably take the grinder to that and smooth out a quarter to half inch or so.

But, the real big issue is on the bottom. It's just too close to the frame. It's hard to get an idea of how close it is in either picture, but one looks like there might be enough room and in the other it looks like it's touching.

I'm not sure what I'm going to do. It's ironic that this big clunky old air starter fits like a champ. I had a good 3/4" around the whole thing. I could easily get my hand around it. Not so much with the electric one.

Oh, and another thing that isn't really shown in the picture, with the adjustable ring of the starter mount, there is no way to get a socket on the heads of the bolts. The only way to tighten them is with a wrench and it's too much of a pita on the top bolt. If I stay with this starter, I might have to look into getting bolts with smaller heads or maybe allen heads.

I also ended up redoing the crankshaft pulley. I didn't like the way it turned out for two reasons, the welds that I filled in the "V" grooves weren't that pretty and subsequently, the machining of the serpentine grooves weren't as clean as I had liked it to be. And, another thing is that the pulley was pretty far away from the front of the block taking up precious space. So, I had a new hub machined to fit a March aluminum pulley.

The whole setup is a few pounds lighter than the big cast iron pulley and it gives me almost a full inch more space between belt and radiator.

Sorry about the low quality of the pictures. I just took them and it's pretty dark out.

That's about it for right now. I've got the front crossmember off and I'm churching it up a bit. Things I still have left to do before firing it up: Mount the remote oil filter, plumb the fuel lines, find upper and lower radiator hoses, weld up intercooler tubing. I'd also like to hook up a few gauges.
 
So im just curious and have to ask from a lessons learned by others aspect. At this point, are you still satisfied with your choice to run this engine? Or at this point, do you wish you have just done a cummins and been long running by now? I understand the need to have a project. Whenever i finish one i feel slightly lost and start thinking about whats next. So, Do you wish you would have done a cummins so it could be done by now or is it worth it in terms of having it as your a project?

Not so much, but I sometimes think that it'd be nice to have a truck that runs (especially when I'm loading stuff in the back of the wife's yukon). :doah:
 
Good choice with the electric starter, I'd think you'd have problems with the air starter i.e. air volume.

If you think the starter might rub the frame when flexed put in some bits of rubber to prevent it from chaffing.
 
I like the fact its not a cookie cutter Cummins build. The Cummins is cool and all, but even with less overall power, this is way way way higher on the cool scale. Plus 2 stroke Detroit's have cool stamped all over them.
 
I've been keeping busy, just not too much with my truck. I've had to pull my motor in my Harley and any free time, I'm trying to finish up with that. I've messed with the intercooler mounting a little bit.

When I mocked it up in front of the radiator, it seemed like it would be an easy project. It fits right in the center of the of the radiator support. I welded up the intercooler and placed it in. Unfortunately, the factory position of the radiator is offset to the driver side :confused: and when I mocked it up, I placed the radiator in the center. I'm going to have to cut and weld the radiator mounts to center the radiator in the center of the support. And then, come up with a way to hold the radiator in place from the top. I wanted to keep this as factory as possible, but it looks like it's going to take a little more effort. You can see in the picture where the stock mounts are directly under the arrows.

Well, I got a little bit done today while the boys were napping. I finally finished my oil filter mount and lines. I don't really like that the filter is mounted so high, but I think that's just one of the things I have to chalk up to "having a 4-71 in a 1 ton". I am thinking about running an oil accumulator anyway.

I also pulled the manifold and drilled and tapped for the Isspro pyrometer probe.

fyi 1 tab on pass side is stock . and extra 2nd tab is for the 6.2 rad extra width . just so you or others know for later info .

and its SEXY to see a 4-71 in a k30 cant wait to see some burnout

Yeah, my stock radiator uses the outside tabs, but they're not centered on the bulkhead. I've got a lot of cutting to do on this anyway, the radiator mounts is just one more thing.

You and me both!
 
This is one of the ongoing builds that I am really excited to see finished.
