Volvo VB 78 Screed Parts Catalog 20037317-C – P6870C P6820C P7820C P8820C

Description

Volvo VB 78 Screed Parts Catalog – Reference 20037317-C

This is the complete parts catalog for the Volvo VB 78 screed family, issued by Volvo Construction Equipment under reference number 20037317-C and dated 2015-10. It covers the Volvo Variomatic screeds with gas or electric heating, single tamper and vibration, in both ETC (electric heating) and GTC (gas heating) configurations, across the full working width range from 2.5 m through 9.0 m.

The catalog is written for anyone who needs to identify and order the correct components for a VB 78 screed – workshop technicians, parts counter staff, and owners keeping a paver in service. Every assembly is broken down into exploded illustrations with position numbers, and each position number is tied to a Volvo part number, quantity, and description. The Volvo VB 78 screed parts catalog 20037317-C covers screeds fitted to the P6870C, P6820C, P7820C and P8820C pavers, including the China-market P6820C variants.

IMAGES PREVIEW

What ties all of this together is the numerical index at the back of the catalog. Every part number that appears anywhere in the book is listed there with the group, section and page where it is documented. That means if you already know the Volvo number you need, you can jump straight to the drawing and see exactly where the part sits, how many are required, and what surrounds it. For anyone working on a VB 78 screed day in and day out, that single index turns the catalog into a lookup tool rather than a browsing document.

What This Parts Catalog Gives You

The catalog is organized the way Volvo builds the screed – by system, then by assembly, then by individual part. Each group opens with a text page listing part numbers, quantities, and multilingual descriptions, and the associated illustration page shows the same position numbers on an exploded drawing. The relationship between the two is direct: position number on the drawing, part number in the table.

Electric and gas screeds share a large part of the catalog, so an ETC and a GTC machine are both covered in the same document. Where the two diverge – heating elements versus burners, thermo control versus gas heating electrics – the catalog separates them into their own sections so you are not left guessing which version a part number belongs to. Each section header carries the relevant product version list, so you can confirm at a glance whether a given page applies to your exact screed.

The catalog also carries a product and equipment variants index that maps kit numbers to the screed and paver combinations they fit. This is the fastest way to confirm that a specific electric or gas screed assembly belongs to a P6870C, P7820C or P8820C machine, and it removes the risk of ordering a component that was built for a different working width.

Who This Catalog Is For

This is the reference to reach for when you are rebuilding a tamper, replacing a vibrator shaft, tracing a gas burner fault back to a solenoid valve, or ordering a replacement deflector plate for a 1250 extension. It is equally useful when a machine has been rebuilt over the years and you need to work out which variant you are actually looking at – the product version tables make that identification straightforward.

Because the catalog covers both the electric and gas versions of the VB 78 in all common working widths, one document serves an entire fleet rather than a single machine. That is the main reason this particular catalog holds its value: it is not a slice of the screed, it is the whole thing.
