gm part breakdowns

[gmcman]

Is there any books a person can buy or computer programs that will give all the parts breakdowns for a particular year vehicle? It would be sooo cool to have something like this so you would know how something goes together but also you could just walk into any GM parts dealer and order part # 123xxx and so on!!!!

well, the factory manuals are out there.... and from what I've seen, those diagrams are what the counter guy has on his system to pull part numbers from... it's worked for me when I've needed stuff. Older Jeeps had parts books with the part numbers but I don't think GM made anything like that????

Check out FEEbay (eBay) for the factory ones. Search for your year and include Helm in search.

I got luck and found mine for less than $30 these IMHO are rarer since it was the parts department that used them so not like two or three per dealership.

So you can see what they look like..

This is what the parts number pages look like.

Here is a page from the service books

The Helm Books

Here is a place to start http://www.factoryautomanuals.com/ and then check eBay and compare prices.
Good Luck and happy hunting.

Yours has part numbers??? My '91 manual set doesn't

No this is the parts book it is different that is why I posted this picture.

These are what the service ones look like (these are for a 1989) but you get the point.

I got all the books for mine (1987)
1.) Unit Repair
2.)Light Duty Truck Fuel,Driveability and Emissions
3.) Service Manual
4.)Wiring Diagram Booklet
5.)Parts & Illustration Catalog

All were bought off ebay for under $100.00 and that was with shipping. I have only seen one other Parts & Illustration book and I think ryoken brought.

Are those parts manuals by year or are they like the service manuals and cover a range of years sometimes? I know for the service manuals, 74 was the last "full one" they put out for my Blazer year, but they did supplementals in 75. Not sure about 78 yet.

You should be aware that the service manual anymore is your better bet. If you can find the parts manual too, bully, but the sad fact is, GM is terrible about keeping parts for vehicles our age in production or stock. If I had to guess, I'd say 50-75% of the parts are no longer in the system. Thats about what it comes out to when I look them up.

So you get nice diagrams, and the hope that the part number you found still is valid, but many times it's not.

Also, there are two books for the parts manuals (at least later on) the numbers and diagrams books, and then a book that is solely numbers, which covers parts that are physically identical, but that have hundreds of small variations for each year/vehicle, like speedometer gears, torque converters, etc.

Aha, I guess I should read a little more closely. I have the '91 R/V/P Service, Unit Repair, and Wiring manuals, looks like there are some more to add to my collection.....

Maybe they will have fewer discontinued parts for the V series?

 

[dyeager535]

Nope. GM cares not about the vehicle age. True, the newer the part is, the more likely they'll have it (which is still not that likely) however, back in 2000 I was looking for parts for a 1991 R/V (Blazer actually) and they were already discontinued. So less than 10 years old and you already couldn't get factory parts. Talk about great customer relations.

Oh wait, I must mention however, that if you have a Corvette, it is very likely GM still has your part in stock, even if it's for an '80.

Also, to clarify my last post on the parts listing (not the diagrams) it covers EVERY part number, but you only really need it for things like speedo gears, etc. Things like the topper seal for a K5 there was only one part number, so it's listed in the parts diagram. Otherwise you'll see something like "GRP 4.2325" which means you have to look it up in the parts listing, for exactly the part number/piece you need. Part number books also show the body styles, driveline lengths, etc.

For me, the exploded view diagrams are awesome when re-assembling something.

Yes, you can take it apart very carefully, and reassemble it the same way, but with most of our rigs over 20 years old, it's quite likely that a particular component has been taken apart before (and often by someone who didn't have a clue) so it may not have been re-assembled correctly and may be missing parts.

The exploded view diagrams are a great help!
