sneak peak at the new diesel bike build

[Dougy]

Hey mate, your build here is fantastic, I always look forward to your updates too, really really top end stuff, its gona be awesome ......now get back to work, I want to see it go !

[dethmachinefab]

Thanks dougy, ill be done as fast as i can! I have a ton of other work to do other than the bike, so it may be a while.

Next step is to remove crank, and bring the rotating assembly to be balanced. Then comes final assembly! (I hope!)

[espe]

Respect!!! You rock man! It must be nice to have the skills and machinery to create such a proffessional build.

[Rhynri]

This looks fascinating. Can't wait to see a video of the final project! I am rooting for you!

[dethmachinefab]

Ran into an issue with ring fittment that needed .004 taken off the axial height of the new top rings. Pistons are already hard anodized so recutting ring grooves was a non option.

Lapping piston rings.

[dethmachinefab]

All material ordered to build the front end. I have decided to build a monicoil linkage front end, similar to a springer with a few diffrences should make a good performing fork set up.

Thanks for the good words, stay tuned.

[Rhynri]

Looks amazing, can't wait to see her scream, and thanks for your advice on the thread for my bike!

[dethmachinefab]

Brought the rolling chassis outside to get a better look. So far engine is complete and mounted, driveline is done, working on dry sump plumbing and turbo header now.

More pics.

[Rhynri]

Amazing. Love the rim-mounted front disc rotor. Looks gorgeous. Wish i had half your metalworking skill.

[Sphere]

Actually I think the build is excellent except for that ugly piece of metal in those beautiful aluminium rims.

Very keen to see how the drive train part will work out.

[michael.kitko]

Very nice build...did not know you had a build thread on here till I ran across this. I always look forward to your updates...keep up the amazing work...

Subscribed. This looks wicked.

Welded up header, and start of the oil tank. This will be the storage tank the oil will flow to after leaving the deairation tank.

[coachgeo]

In your oil supply tank; did you put a baffel or some pocket of any kind to ensure no matter what angle the bike sits she's still going to have oil for the pump to send to the engine for example the ever rare laying of the bike on it's side while heading upgrade a steep hill

[dethmachinefab]

The lower oil tank will be allways completely filled. Another tank above it will be where the scavenge pump dumps the airated oil, swirling around the tank. In that tank are baffles to separate air and oil. After separation it flows down to to storage tank. It should allways be full because the scavenge pump pumps more that the engines oil pump by a large amount. From the bottom of that tank it then feeds the oil pump in the engines front cover, providing cool deairated oil.

Building another 3cyl bike.... .

If you said it in this thread; appologize in advance for not finding it.

What Kubota is that? D722, D902, D???

A tid bit for future if it is a D722. Just discovered there is what appears to be a smaller in height/depth (LOT SMALLER?) but wider alluminum HD oil pan for the D722 engine. It is used by the Carrier/Transicold line of Reefer's powered by the D722. Was told there are engine mounts built into the pan! Might be interesting to cut and splice this thing. Like say a taller section on the sides against the outer portions up against the lower sides of block. If it didn't impede lube that is. Similar; just taller, to what is done on the oil filter side of the attached pics allowing for even less depth in pan?. Most of all this would keep less depth yet wrap the pan around bottom of block reducing width / improving protection in a lay down. Would have to go to remote oil filter .. If it does not make engine moutning impossible.

[dethmachinefab]

Im using a d1005. I used a similar pan on my old yanmar bike, that came from a thermo king unit. I would be very weary using the mounts in the pan. Certainly not in a rigid mount situation.

Progress may be delayed on this bike for a little bit, have another bike to build.

Sorry do not mean to hijack. If too much pan talk starts here I'll move things out of this thread into a new pan thread.

With that said....... on the previouse built bike w/Yanmar/TKing pan..... did it shorten the height of the whole engine much compared to stock pan? how much you guess?

On this thread's bike; looking at the thickiness of the material you used for your dry sump belly pan and its additional plumbing, how much additional engine height reduction did you gain going that route compared to going with something like a wider TKing/Carrier like pan?

[dethmachinefab]

The yanmar did not lose any height because the pan was wide, and still held 1.5 gal with capacity reduced by 1 gal. The best way to fit an engine low is make the oil pan sit between frame rails. Depth is important because oil will slosh front to rear and a shallow pan may let the pickup run dry in certain situations. I will get a picture of the pan i modified today for that new cat engine.

The kubota dry sump is only 1" tall. Original pan was about 7" deep. I gained a ton of room with that, although it was not its main purpose. The added complexity takes up room elsewhere though, and is not easy to fit.

Good points about dry running. In my situation though (a Tiger) and same any other hanging engine style cycle frame...... there are no frame rails under the engine. The engine block itself is meant to be the frame rail in a sense.

[dethmachinefab]

Worked on some charge air cooling and intake piping today.

[Byrdman]

Absolutely wonderful build thread. Can't wait for more............

[dethmachinefab]

Worked on the charge air cooler mounts and some exhaust.

[coachgeo]

Looks SWEET.

where you getting belt drive components from? (from tranny to rear wheel). For changing ratios; are there lots of sizes available in ribbed belt pulley/sprockets?

[XLerate]

Just keeps loking better and better, Fabber. Of course this ain't your first rodeo and that's some beautiful workmanship, or better said: Craftsmanship! Invaluable info from the visuals for my own planned Kubota bike build, thanks!

[henneberg]

Yes, I like the "nothing left to arbitrariness" way of work, all details are in control, very nice

[dethmachinefab]

Thanks for the good words!

Coach, there is a large assortment of belts available as well as pulleys in the harley type market. If that is exhausted looking to industrial belt suppliers is next, many more sizes to be had there as well. The belts and pulleys are not cheap when sorced new, but the performance and light weight is far worth it in my opinion.

[dethmachinefab]

Not much progress on this, i have been busy with other work and some real estate stuff.

Fuel tank and oil tank are done, some plumbing, and crankcase vent done.

[kapis]

Hey man! I really like your build is there any news on it?
