Diesel CAD drawings

You might try contacting Bosch. They have supplied FI parts to every auto manufacturer to date. If you can convince them that you are going to be buying components from them, I would think they would be willing to five you detailed drawings. Good luck.

Thanks Bob

I just completed a major design for a high vacuum environment in which I was often able to use 3D models, from the vendiors engineerin dept, of off-the-shelf, production components.

Getting 3D models is becoming increasingly easy, especially when the vendor is savvy enough to recognize that if his part numbers appear in the BOM, the odds of his being invited to bid improve.

Some vendors like McMaster-Carr offered 3D models of common components as a regular service long before SolidWorks and AutoDesk offered "toolbox". And, they are available in native formats (Solidworks, Pro-E, etc) or in neutral file formats (IGS, STEP, etc).

The NFF's won't be parametric but so what? Who wants to waste time designing a 10 x 32 screw or a roller bearing or oil seal anyway especially when the vendor can provide it?

Call the manufacturer. Demand they provide a 3D solid model. If a sale is at stake, and the volume during production appears substantial, they'll bend over backwards to help. And, if they won't, there's always another firm, that's more hungry and happy to respond.

Thanks for the advice. I am wondering if there are any file sharing sites that deal with this? Like you said, I only need the basics, not proprietary designs.

I've spoken with friends who work as design engineers with Bosch. Since this is intellectual property that is copyrighted, they won't supply such items unless you can convince them that you are creditable and will contract to purchase major quantities of components from them.

You may need to purchase samples for measurement and reverse engineering.

" . . . . . . intellectual property that is copyrighted, they won't supply such items. . "

If that is what is happening, then the designer is asking the wrong questions of the supplier.

You don't need the guts of an injection pump to design the mating surfaces on the respective gear case or coupling, At best you need external geometry to avoid interference, determining fixturing and perhaps allow you to run injector lines and, finally, the mass properties. There is no threat to proprietary design whatsoever.

I once did mods to existing engineering models for transmissions designed and manufactured by an OEM company. We frequently received requests from vehicle manufacturers for non parametric "dumb" models with the precise external geometry of the housing and fixtures so that the customer's engineers could design their suspensions and drive trains to fit our product. The model inside had no gears, differential or sub assemblies, There was no intellectual property at risk. How could we refuse such a request, frustrate the prospect's design needs and expect to get an order later?

This is exactly why I stated that the OP may need to purchase samples of the components that he will need to complete his analysis and design.

OEMs are going to great lengths to protect what they consider is their intellectual property. I am not saying that they are entirely correct, but the practice is growing.

good comments, thanks!

Thanks. I have given that some thought as well. I want to use the manufacturers off the shelf items for my running prototype. This is not such a bold design to need new parts made for it. I would happily laser scan and reverse engineer to get a 3D model if I must. I hope to find some engineering student who may have this already. I did see some 3D models of high pressure diesel pumps on youtube. Thanks for your comments

Thanks! I hope I do not need to buy samples as that may drive the costs up. I will if I am left with no alternative.

I'm just glad you're using SolidWorks. Any other software would just be stupid. AND, calling the others "CAD" would just be an insult. I've used many and they just don't compare.

Great opinion!! Too bad it's wrong!!

More on topic; most CAD systems now provide a facility to output watertight representative models that remove any interior details of a design. There is no excuse for a manufacturer NOT to provide models of their products. IMO, that excuse is a red herring covering up other issues.

Now, if I could just get my higher end customers to dumb down some of the models they send me for integration into our aircraft models. I had one send me a model of an antenna that had over 200 internal components included. All we needed was the footprint, overall envelope, and bolt hole mounting details. I had to dumb it down myself to keep from overloading my assembly.

Durn it. Couldn't get my edit in on time, so had to reply.

PS- almost forgot to mention. Our engineering department tries to ONLY do business with vendors that will provide 3D models of their equipment, either native Inventor or STEP. Oftentimes I have to contact their engineering groups directly if the parts aren't offered through their websites. I've found most companies are very accommodating when approached directly.

From the discussion I'm guessing your not designing this as a professional engineer looking to compete in the market place. If this is a hobby then you might be in a tough spot, but if this is a school project you might be able to get access to some older designs. I had success getting some landing gear subassebly details from an aerospace subcontractor to Boeing while I was in college. I just walked in and asked the secretary if there was someone I could talk to about CAD work in the aerospace industry, and she gave me a couple of names to persue. I took about two months, but I was able to build a relationship with one of those names and he was interested helping a college kid. The design I received was from the 70s (in 1992), but it was something to work with. I should mention the being from the 70s I recieved detailed drawings which I had to recreate in CAD, but again if you want functional it does save a lot of engineering and design time.

Thanks for your comments. This is not a hobby or a student project. Due to its nature I cannot discuss actual details but it is a straight forward project that needs to be extensively modeled before receiving funding. It will compete in the market place in a niche we are creating.

I'm with the other guy. You only need external dimensions for mounting and clearance. They will probably be happy to provide you the specs on the capabilities of the pump since that will be important as well and will mostly likely NOT be on any dimensional prints. As for the guest who posted about Solidworks, I suggest you try other software. I've used autocad, inventor, Catia, Pro E, Alibre, doubletree and of cource Solidworks. Solidworks is capable software, but it is by no means the 'best' at anything.

Thanks. I agree about the dimensions. I already have Solid Works because it is what most of the prototype machine shops in my area prefer.

Thanks to everyone who commented on this thread. I looked at a couple of sites that offer CAD drawings so it looks like there is a solution out there on the net. www.traceparts.com looks promising. It looks as if I will need to register and get some sort of license. Has anyone used a service like this? Thanks in advance.
