Topic: Chevrolet P30 Manuals

[DaveVA78Chieftain]

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.
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

Dave yes it is confusing on P30 manuals . my 1987 P30 came with a Chevrolet (4)  manual set
ST- 330 -87    198710-30 Light Duty Truck  Service manual
ST-333-87      1987 Light Duty Truck  Unit repair manual   
ST-376-87       1987 Light Duty Truck Fuel Drivability and Emissions Service Manual
ST-350-87        1987 Light Duty Truck Wireing Diagram Booklet

They sure don't make it easy or cheap Glad I didn't have to buy them
Luckely I havent had to use them much yet either

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
