V8 Diesel Trike... old Uhaul truck

[peteg59]

It will be interesting to hear if the angle will be an issue.
I'm nowhere near an engineer however I would think as long as the pickup tube can get a good & continuous oil supply from the pan, its good?
Theres no float level to worry about as you would have in a carb, and the fuel pump/injectors can typically run at fairly extreme angles before starving out, so what else is there to consider in a diesel powered trike besides looks?

BMB, google 4btswaps Detroit section.....seems they discussed cutting 2-3 in,off an oil pan. maybe widen bottom of pan for same capacity? folks will love that Detroit music! got a 6v53 in a 50 chev 1.5 ton ...bunch of fun!! larry

 

[peteg59]

Rear pinion angle might also be an issue to consider. Don't know how much a stock u joint driveshaft will tolerate, running 10deg."off"?

 

[J.T.M.]

So... now I totally have my panties in a bunch over the angle of the engine and transmission. To get my driveshaft right and have 8 inches of clearance under the oil pan in need 10 degrees maximum angle. This is what that would look like.... freaking engine is jacked back. I'm not concerned about looks, just the mechanics of it. Will it cause issues with the engine?
I will be on the horn with Deteoit Diesel tomorrow begging for help.

You can cut the bottom off the oil pan and put two kick outs on it to give you more ground clearance the kick outs will give you more oil capacity. You will have to shorten the oil pick up. We do this on race cars all the time.

The rear pinion won't be 10 degrees off. As I stated earlier, I cut the saddles off of the rear axle to allow me to roll the differential/pinion to an upward angle to match the angle of the engine/transmission. The offset to allow the u joints to work will be handled by the pinon shaft which is not dead center on the axle.

I have considered oil pan modification. I will avoid it if I can. These engines are also put in boats. The marine versions of these engines have different oil pans, water cooled exhaust manifolds, and all kinds of stuff. Detroit has so many variations of these engines it's insane. Hopefully I'll get a detroit guru to pass on some knowledge about max allowed mounting angle for my model engine.

 

[BMB Guns]

So... Stewart and Stevenson hooked me up with a spec sheet... max up angle 20 degrees. Max down 30 degrees. I'm going to shoot for 8 degrees if I can and get larger diameter tires to increase my overall ground clearance. We have floods around here. I need to keep my feet dry.

Nice, how long is the shaft?. ...I like it

11 1/4 center to center on the u-joints ! That is with 1 1/4 of spline pulled out. That should be plenty of travel for my application.

 

[BMB Guns]

Quiet but still working!!!

Well, the clutch is in, transmission bolts up, engine mounts are fabricated and installed, front of frame is cut and capped off with a big ass piece of channel. Slow but steady

 

[BMB Guns]

Running in the frame!!!

Great to see some more forward progress on your trikeThumbUp
Are you setting it up more for the drags, or street?
Looks & sounds good with the turbo spoolin'!

Oh this will be a grocery getter and road triper! My cousin also owns a biker bar just down the hill from my shop so I guess I'll be there alot too!

 

[Gorilla]

Sure sounds SWEET

Haven't posted in a while. Project is not dead just taking a back seat. I added a new machine to my shop! Can you say "custom heavy duty steering neck!" ?!?!

....annnnnd... my pic is sideways... :/

 

[peteg59]

New shop equip. looks good Brady. :clapping:

After a 5 month break, bout time to get back to work on that trike now, isn't it?

wish that lathe was in my shop! 353 sounds great,

did you finish your trike yet? would like to know how the front end works? would like to use build something like it to run car rim on front. thanks

Looks like this puppy died on the vine.

BMB, I have been around the trike building community for a while and have actually seen a few truck based trikes. One thing I know they ALL did and it makes your ride much more comfortable. Do some research into removing some of the leaf springs. As I am sure you already know that suspension is for very heavy loads, you could remove a bunch of them and improve your ride while still being safe.
