Starting the Gniezno Speed Car Motor with Lublin Transmission

Blog Article


Starting the motor of a Gniezno speed car equipped with a Lublin transmission involves unique considerations for this vintage Polish automotive technology. Gniezno-branded vehicles, produced in the mid-20th century, combined local engineering with robust Lublin transmissions—known for their durability in commercial and passenger vehicles. The starting system, featuring a starter motor adapted to handle the transmission’s mechanical demands, requires specialized procedures to ensure reliability in these historically significant automobiles.

Vehicle and Transmission Background




  1. Gniezno Speed Car Overview


    • Production Era: 1950s–1960s, developed by the Gniezno Automotive Works in Poland.

    • Engine Types: Typically 4-cylinder, 1.5–2.0L gasoline engines with overhead valve (OHV) design.

    • Performance: Top speed of 80–100 km/h, designed for urban and rural use.




  2. Lublin Transmission Characteristics


    • Design: 4-speed manual transmission with helical gears, derived from Lublin truck technology.

    • Unique Features:

      • Heavy-duty clutch designed to handle high torque fluctuations.

      • Integrated starter ring gear with 110–130 teeth, compatible with the starter motor’s pinion gear.






Starting System Components




  1. Starter Motor Specifications


    • Type: 12V DC, 0.8–1.2 HP permanent magnet starter.

    • OEM Part Numbers:

      • Early models: 312-001 (Polish-manufactured).

      • Later upgrades: Similar to Soviet-era VAZ starters for compatibility.



    • Mounting: Bolted to the engine block adjacent to the flywheel, aligned with the Lublin transmission’s ring gear.




  2. Electrical System


    • Battery: 6V or 12V (post-1960 models), 45–60 Ah capacity.

    • Ignition System: Points-type distributor with a coil and condenser.




Starting Procedure for Gniezno Vehicles




  1. Pre-Start Preparations


    • Transmission Check:

      • Ensure the gearshift is in Neutral; depress the clutch pedal fully to disengage the transmission and reduce starter load.



    • Fuel System:

      • Prime the carburetor by pressing the accelerator pedal to the floor once (for cold starts), then releasing it slightly.






  2. Cold Start Routine


    • Choke Engagement:

      • Pull out the choke knob (located on the dashboard) fully for temperatures below 10°C (50°F).



    • Ignition Activation:

      • Turn the key to the "START" position, holding it for 3–5 seconds. The starter motor should crank the engine smoothly.



    • Warm-Up:

      • Allow the engine to idle at 1,000–1,200 RPM, pushing the choke in gradually as it warms (5–10 minutes in cold weather).






  3. Hot Start Considerations


    • Flood Prevention:

      • If the engine has been running recently, do not use the choke; fully depress the accelerator while cranking to clear excess fuel.






Common Starting Issues and Solutions




  1. No Crank from Starter Motor


    • Electrical Faults:

      • Check battery terminals for corrosion (common in vintage vehicles); clean with a wire brush and apply petroleum jelly.

      • Test the ignition switch for continuity; replace if worn (parts available at classic car suppliers).



    • Starter Motor Failure:

      • Tap the starter body with a mallet while cranking; if it starts, the solenoid is likely stuck (replace the starter or rebuild the solenoid).






  2. Cranking but No Ignition


    • Fuel System Problems:

      • Check for clogged fuel lines or a stuck float in the carburetor (e.g., ZMZ-21 carburetor common in Gniezno models).



    • Ignition System Faults:

      • Inspect points for pitting; adjust the gap to 0.3–0.4 mm using a feeler gauge.

      • Test the spark plug wires for conductivity; replace with modern silicone wires for reliability.






  3. Grinding Noise During Start


    • Gear Misalignment:

      • The starter motor’s pinion gear may be worn or misaligned with the Lublin transmission’s ring gear.

      • Solution: Inspect both gears for damage; replace the starter pinion (e.g., part #312-001-12) and check flywheel teeth.






Maintenance for Vintage Starters and Transmissions




  1. Starter Motor Care


    • Brush Replacement:

      • Every 2–3 years, disassemble the starter to replace carbon brushes (length should be ≥12 mm; use VAZ-2101 brushes as a substitute).



    • Lubrication:

      • Apply lithium-based grease to the starter shaft and pinion gear annually to prevent binding.






  2. Lublin Transmission Maintenance


    • Clutch Adjustment:

      • Check clutch free play (15–20 mm at the pedal); adjust the cable or hydraulic system to prevent excessive starter load.



    • Gear Oil Replacement:

      • Change transmission oil every 10,000 km with SAE 80W-90 GL-4 gear oil to ensure smooth shifting and reduce starter stress.






Historical Significance and Restoration Tips




  1. Preservation Notes


    • Original Parts:

      • Gniezno starter motors often bear manufacturer stamps (e.g., "GMW 1958"); preserve these for historical value.



    • Upgrades:

      • Modernize the electrical system to 12V with a voltage regulator to improve starter motor performance and battery life.






  2. Community Resources


    • Join Polish vintage car clubs (e.g., Klub Motorowy Gniezno) for specialized repair knowledge.

    • Source rare parts from salvage yards or online marketplaces for classic Polish vehicles.
