Bomag issued this 815-2, BF 815, LPH 814-2, BF814 parts catalog PDF under its own document number, 0852807, and the 309 pages hold the factory exploded views and part numbers for these self propelled pavers. Track drive assemblies, conveyor bed, hopper augers, steering, gate assembly and hood fill the opening chassis section; hydraulic hoses, valve assemblies and the full 15 ft screed follow, with hydraulic and electrical schematics closing out the book. Screed breakdowns split by serial number, so if your machine falls in the 911835291042 range it gets its own drawings instead of a near-match. Ordering a wear plate or extension cylinder off a guessed number means freight, a return, and a paver standing while the plant keeps loading trucks. Bookmarks put you two taps from the right assembly: check the drawing, read the number, order once.

Bomag 815-2, BF 815, LPH 814-2, BF814 Common Problems This Manual Covers
Bomag BF 815 screed extension cylinder seal kit part number not stamped anywhere on the cylinder
Check the 15ft screed exploded views starting on page 146. Verify your serial number first: machines from 911835291042 to 9118355291045 use the later screed section on page 206 instead. Match the extension cylinder callout in the guide tubes drawing to its parts list line, then order the seal kit by that number.
Manual Section: 15ft Screed and Arms (Bf 815) p. 146Can't match a blown conveyor motor hose to a part number without the original tag
Inspect the hydraulic parts diagram on page 112, where the conveyor motor lines are broken out by circuit. Verify the routing against the hydraulic schematic on page 295 so you don't order the pressure hose when the drain line let go. Record the callout number, then pull the part number from the matching list on page 113.
Manual Section: Hydraulic Hoses and Tubes p. 112Vibrator speed control valve on the machine doesn't match the drawing, can't pick the correct assembly
Verify the valve against each exploded view in the valve assemblies section starting on page 120; the vibrator speed control, stack valves, pause and run valve, and bank blocks are all drawn separately. Compare port count and mounting face to the drawings, then check the hose connections on the hydraulic schematic on page 295 before ordering.
Manual Section: Valve Assemblies p. 120Stocking spare seal kits, O-rings and filters but unsure which kit numbers fit this machine
Check the Frequently Used Parts list first; it gathers the seal kits, O-ring kits, filters and fan belts in one place so you are not hunting through every system group. Verify each hydraulic filter against the parts diagram on page 110 before ordering, and keep a set on the truck so a clogged element never stops the machine mid-mat.
Manual Section: Frequently Used PartsBurned wiring connector in the main harness, part marking melted past reading
Inspect the wiring diagram on page 302 and trace the failed circuit to its connector callout. Verify which sheet covers your machine, since diagrams for all four models are grouped in the electrical schematics section, then order the connector and terminals by the numbers on that sheet so the paver is back in the pass this shift.
