Project: Tow-Rat (Lil' Blue)

Awesome build! Keep up the good work!

Looks good in there, at least you will have a little bit of room from the back of the motor to the dash.
Your not supposed to do that type of transaction with your wife around.

battery tray's in, including a bolt welded to the frame to attach the ground strap. fuel cell mounts placed, but not totally convinced i like them yet. i need to get fittings on there and make sure i have enough room under the bed floor. 19gal x2, the current plan is to simply tie them together into one volume. no dual tank value needed.

[lower50's]

Well you won't have a range problem that's for sure.

new power steering pump n bracket to delete the factory vacuum pump gives me all kinds of room for motor mounts! and one less oil leak.

drew up the shock mounts. decided to use RS9000XL shocks for the adjustability, so i hit up service and got a PDF with every shock they make listed with lengths and eye's. took a bit to go thru, but found some.

also sandblasted a factory bezel before i made a backing to mount gauges. the plate is actually CORTEN and will most likely get a clearcoat to keep that look. at this point i'm leaning towards one gps Speedhut speedo centered low, and 2 Banks iDash datalogging gauges above. can display anything and everything i'd ever want, plus datalog and tune the 12v when i start playing with it. i probably won't order those until i get the body back on the chassis for good though.

so i'll be really disappointed if i never get the chance to throw way too many PSI's at this motor. with that in mind, and my current record of blowing out drive shafts, i wanted to make sure i gave this every chance to live. enter the 1410 series u-joints, ram used them factory on some HD applications and is what the truck-pull guys will upgrade to as well.

i need a 2pc drive shaft just for length alone, and to get out from under the cab easier. i also wanted a CV rear shaft with the CV flange fixed right at the truck arm pivot. this would give me the "perfect" shaft angle thru the entire range of travel. this all meant that i needed a fixed carrier bearing at a different angle than the forward shaft, so really you could maybe call this a 3pc drive shaft. the carrier bearing or mid shaft, will be at the same 6.5deg as the transmission and have a standard shaft between the trans to bearing. the bearing will be fixed to the chassis and give me the fixed CV flange output to the axle.

so the offroad rock racing guys also use 1410, and Branik Motorsports sells this ultimate carrier bearing. however they only sell it with a standard yoke on both ends. Dodge used a 1410 CV in the front of some 4x4 trucks, and dimensionally i figured it could be used in the assembly. i bought a used yoke, mailed it to Branik, and they machined it to work! 32spline chromoly shaft, shimmed bearing pre-load, and ready to weld in. can't weld it with the bearings in there, so once it's fit i'll pack it with grease and install the seals.

small weekend update ... i ended up sleeping more than anticipated cuz my plate order didn't show up. stupid USPS. i guess i also worked on the street jeep some, wired up new Hi/Low heated seat switches Rain this weekend washed the roads clean so i can start driving it to work again!

got the front shock mounts all dialed in. also got the front clip body mounts all figured and ready, but didn't finish. maybe i'll do that tonight.

if anyone is interested, the mounts are made from old ford truck bolt-on mounts that i cut up. i've used them a lot on jeeps before, they are a great starting point.

Ya I think you will have a hard time braking that, but I don't think your poor little 1/4 drive impact with that huge socket on it will have enough torque to tighten the nut properly

i was an engineer with DeWALT Cordless for 7 years before coming back to Pittsburgh, i have a few other toys i could use

oooohhhhh yeah! she officially holds her own face finally!

you might also notice that i chopped out the rad mount and welded it back in. it used to stand proud of the support, but i made it flush to gain another 1/2" of clearance. was going to go further, but this was easier and still helped.

[youngrodder]

Very nice....we need to see a picture with the front sheet metal and laid out.......

[6DoF]

yes sir!

so page 2 post 62 is pretty close picture ... but i have to wait til the engine is mounted to move it off the current blocks. my plate should have been in on friday, but USPS sucks pretty back and no estimated arrival now.

[6DoF]

so that's not going ANYwhere. a little alignment, a little more strap rubber, a few hoses, n fill it.

she now holds the 12v! I'm super happy with the fit/function of these mounts, they aren't going anywhere. but they just lack something, they don't have the same style as other bits on the truck. they are missing with my eye, but unless i come up with something super easy, they aren't getting changed. front of the crank sits 1/2" passenger, and the trans output is 1/4" passenger to help gain clearance for the starter (and a throttle pedal)

[youngrodder]

Nice job on the motor mounts. They should work. They look very robust.

YYYEEEEAAAAAAAHHHHHSSSSSSSSS!!

I might have done some things out of order n had to re-do em ... But she's officially hanging. The crossmember should be good for the chassis, was easy in n out, and won't let that trans go anywhere.

I love the flat belly pics, b/c racecar

Nice job!! Will the rubber in the motor mounts give enough for the shake of the diesel? Love your tube work.

[youngrodder]

Love your fab work. The braces and motor mounts look great.

Ditto, thanks!

thanks! i do love my bender

so on the bushings ... i guess we'll find out! i used similar poly bushings for engine mounts on the GM 6.0L in my other Jeep, and they're great. a buddy who has a 12V in a square body used windshield installation urethane to inject his factory Ram motor mounts to fill all the voids. not only does the built engine move a lot less when romping on it, but i actually thought the vibration harshness in the cab was better. it was really different from the stock Ram i drove. i don't know what their original build metrics were for NHV, but i've never thought any factory decisions were the right compromise for me.

side note: if you try and shake the motor, because of the preload in the bushings with the weight, there is NO give in the bushings and the whole chassis moves. if you try and wiggle the trans tail shaft back n forth without the crossmember, the engine mounts only let you muscle it maybe 1/4" total motion. she's locked in

made some shocking progress this evening
