Spare Parts & Maintenance for Model 40B

Maintenance & Spare Parts: Keeping Your Model 40B Running for Decades

The Numberall Model 40B Numbering & Lettering Press is legendary for its durability—built entirely from heat-treated tool steel and cast iron with no plastic, electronics, or fragile components. Many units from the 1940s and 1950s remain in daily use on shop floors, delivering crisp, permanent indents on keys, pet tags, nameplates, and flat parts.

With basic proactive care, your 40B can easily last generations while maintaining precision alignment and smooth operation.

Regular maintenance is simple and mostly in-house. Stocking a few common spare parts eliminates downtime, and our massive inventory ensures quick access—even for decades-old machines.

Recommended Spare Parts to Keep in Stock

These high-wear items are the most frequently replaced and readily available from Numberall:

• Table Inserts — The top surface bears repeated heavy impacts and can gradually warp over years. Adjustable fore/aft for perfect line spacing; replace to restore flatness and alignment.
• Character Dials — Engraved with 42 characters and heat-treated for hardness. Stock extras in your sizes: 1/16”, 3/32”, 1/8”, 5/32”, or 3/16” for quick swaps or font changes.
• Spacing Racks — Match your dial size and part length; extra-long tables/racks available for larger tags.
• Standard & Custom Nests/Fixtures — Universal key nests or strip holders speed setup. Custom nests tailored to your unique parts boost throughput and consistency.

Pro Tip for Vintage Units: If you are operating a 40B manufactured before 1970, our modern heat-treated dials and spacing racks are still 100% compatible. A simple dial upgrade can often restore “factory-new” crispness to a machine that has been in service for 50+ years.

Model 40B Maintenance Checklist

Follow these guidelines from our official user manual to prevent wear and keep operation smooth:

1. Lubricate Bearing Surfaces with Light Oil – Location: Dedicated oil hole on the front of the press, just below the spacing adjustment screw.
   • When: Apply a few drops if surfaces look dry.
   • Frequency: Once daily for continuous heavy use.
   • Tip: Use a light machine oil—keeps pivots and bearings free without gumming up.
2. Use Dry Lubricant on Sliding Surfaces (CRITICAL) – Do NOT use oil here—oil traps metal shavings and debris, causing a gritty feel and accelerated wear.
   • Apply high-quality dry lubricant (e.g., graphite-based or PTFE dry lube) to:
     • Rear character dial surface (where it contacts the dial plate).
     • Table insert guides.
     • Table dovetail strip.
   • Frequency: As needed when movement feels sticky; wipe clean first.
