Chevy P30 Chassis Manuals

DaveVA78Chieftain · March 23, 2013, 11:33 AM

It is not real clear what manuals apply to the Chevy P30 Chassis so I complied a list to make it easier for everyone.
Basically there is a Service Manual and a Component Overhaul Manual. The confusing part is that the P30 chassis is included in the Light Duty Truck manual. It was only in the late 80's that GM moved the P chassis to a seperate manual. It is also my understanding that, it was not until the late 80's that GM moved the wiring diagrams to a seperate manual. There is a general service manual that provides a world of useful information. It covers mid 70's through 1992.

General Chevy MH Service Information

Available to members in the Member Area, Free Manuals Section
Manuals can be purchased on eBay using this link:

EBAY link for hard copy P30 Manuals

Please be aware that Bisko Manuals does cary some of these on CD-ROM which are a lot cheaper.
Hope you find this useful,
Dave

Both confusing and expensive depending on year. Thanks for posting that info. The ST 376 manual came into existance due to emession controls. Not sure what year they moved the wiring diagrams to a seperate book and I suspect P/N format of the elecrical book changes over the years.

I believe some of the confusion of which manuals you need are in the VIN # Code

The 5th digit ( P) means forward control
6th digit (3) Means 1 ton chassis
7th (?) means body code
When I ordered parts I told the GM truck dealer it was a P3 I didn't use the 0 or say p30 that would = (P)= forward control (3)=1 ton
(0)=pickup/delivery van .

The body Type code for motor homes is (7) or P37
The 10-30 light duty truck manuals covers all body Types and chassis for code(1) 1/2 Ton , Code (2)3/4 Ton ,and Code (3) 1 Ton
These are the correct manuals for Motor homes

I believe the P3 is the short version when speaking about MH chassis or a least that's what I call it Hope that helps and doesn't confuse anyone further

I found and purchased the two manuals for the 86 Cheiftan using the given numbers. But the one marked for the electrical ST 350-86 brings up a manual for the Chevette of that year. Is there any chance the number is wrong?

DaveVA78Chieftain · June 11, 2016, 10:53 PM

Should be ST 330-86

Go to the members section, scroll down to the manuals and click on the first one that says chevy P30 I think it is and that will open up all of the manuals for that group. Once you get into the manual section and click on the manual that you want it will go to a page that will let you download the manual. You will click on the download link and depending on your browser and computer it will download to your computer in the downloads section. It is usually displayed in some fashion on the screen. Since I do not know what you have I can't help there.
