This is our small spring clamp for Dubuque John Deere Tractors 420, 430. This spring clamp, also known as a Corbin Clamp, was original equipment in various John Deere tractors including the LP tractors. This spring clamp fits the small thermostat water bypass and the LP tractor Converter LP PreHeat line. This spring clamp is expandable to approximately .8".   Our spring clamps are temperature compensated to maintain a constant good fit under varying temperature loads.  The spring clamps have a semi gold appearance with a zinc dichromate finish. Excellent unpainted appearance.  This spring clamp can be found on page 16-8 and 20-2 of the John Deere 430 parts catalog. These style spring clamps will restore your John Deere tractor to the original clamp style found from the Dubuque factory.
