Lull L-812 1983 Parts Catalog – OEM Factory Parts Breakdown

Tired of ordering the wrong decal and finding out three weeks later it doesn’t fit? I’ve seen guys waste a whole afternoon because they guessed a part number instead of looking it up. This Lull L-812 1983 Parts Catalog is the factory document that tells you exactly which part goes where – including the paint codes and decal locations. No aftermarket copy. This is the original 40-page binder from Lull, issued June 1983, covering serial number 25752 and up. Every part listed here matches the production line specs, so you don’t have to wonder if that decal from a generic supplier is correct. The OEM part numbers are right there on page 4, laid out in assembly order. If you’re doing a restoration or a maintenance rebuild, this catalog is the difference between a correct fastener and a bucket of wrong bolts.

The manual covers three badge variants: Lull L-812, Mahto L-812, and Prime-Mover L-812. All share the same parts breakdown, so one catalog does it for three machines. That’s the kind of cross-reference you won’t get from a PDF off some forum.

Decal and Paint Specifications – Page 4 Details

Page 4 of this catalog gives you the full decal and paint assembly (Figure 1). Ten items listed, each with a part number, description, and quantity per assembly. For example, the Lull decal is part 8-21473, the machine rating decal is P-13295, and the warning decal is L-83875. You also get the paint codes: Gold (52-210), Burnt Orange (52-211), and even the spray can numbers (52-214 for gold, 52-213 for burnt orange). If you’re repainting a mast or chassis, you don’t need to guess the shade. The catalog tells you the exact factory color and the correct decal to reapply after painting. Missing a warning decal? Look up L-83875 and order it – not a universal “Caution” sticker.

Why OEM Parts Matter on a 1983 Lull L-812

Aftermarket parts catalogs are often reprints with blurred numbers or outdated supersessions. This one is the factory issue from 1983. Every part number in here was active when the machine left the assembly line. When you order a Prime-Mover nameplate (B-19903-02) or a clutch decal (P-13300), you get the exact decal the engineers designed. Counterbalanced mason tenders like the L-812 carry loads on uneven terrain – a wrong load rating decal could mislead an operator. That’s a liability. The OEM catalog keeps you legal and safe. If you’re restoring a unit for resale, having the correct decals and paint increases value and avoids inspection headaches. Automotive Industry Overview has plenty of stories about shops that used generic parts and ended up with failures. Don’t be that shop.

Cross-Referencing Part Numbers for L-812 Variants

The catalog doesn’t separate the three brands into separate sections – they’re all in one sequence. The part number column tells you which variant uses each part. For instance, the Prime-Mover decal (B-19903-02) is listed with a quantity of 1, and the Lull decal (8-21473) is separate. If you’re working on a Mahto L-812, you still use this catalog; the illustrations are identical. The serial number cut-in is 25752, so if your machine is older, verify the serial before ordering. No point buying a mast nameplate that doesn’t bolt up. The catalog also notes items marked “NA” (Not Available) – that means the factory no longer stocks them, so you may need to find NOS or fabricate. Realistic, honest documentation.

Use This Catalog with a Service Manual

A parts catalog alone won’t tell you how to rebuild a transmission – that’s what a service manual is for. But when you’re assembling, you need the part numbers. Pair this catalog with a repair manual, and you have both the procedure and the parts list. For example, a Lull LD50 LL40 Articulated Loader Parts Manual covers a different machine, but the same principle applies: OEM numbers prevent ordering mistakes. If you own an L-812 and also run a Lull 644E-42, check out the Lull 644E-42 944E-42 Illustrated Parts Manual – Section: Engine & Attaching Part – same quality of factory data. For the L-812 itself, the LULL M-15BR Operator Maintenance Parts Manual is another good companion if you need operator-level info. But for parts, this 1983 catalog is the one. Access it, print the pages you need, and keep them in a binder on the workbench.

FAQ – Parts Catalog Questions

Does this catalog include torque specs or repair procedures?

No. This is a parts catalog only. It lists part numbers, decal assembly, paint codes, and nameplate locations. For torque values and overhaul procedures, you need the service manual.

How do I know if my L-812 serial number is covered?

Look at the chassis nameplate. If the serial number is 25752 or higher, this catalog applies. If it’s lower, the decals and some parts may differ. The catalog explicitly states “Effective Serial Number 25752” on page 1.

Are the paint formulas included for the gold and burnt orange colors?

The catalog gives the factory paint and spray can part numbers (52-210 for gold, 52-211 for burnt orange, and the spray can variants). It does not list chemical mixing ratios. Contact a paint supplier with those part numbers to get the correct formulation.

Can I use this catalog to order parts from Lull dealers today?

Some part numbers may still be active; others are marked NA. The catalog is accurate for 1983 production. For supersessions, you can take the part number to a dealer and ask for the current equivalent. Many decals and nameplates are still available through specialty suppliers. The catalog gives you the starting point – the number you need to cross-reference.
