Heating the damper in 200º F hot water for 15 minutes will cause it to expand a bit. | + | *The damper is held on by a 0.0007"-0.0014" press fit. Heating the damper in 200º F hot water for 15 minutes will cause it to expand a bit. However, like the dough in a doughnut, when the metal in the damper expands, it expands in ALL directions which actually makes the hole smaller. Overheating the damper also risks damaging the damper and/or the front seal. Chilling the crank snout with a bag of ice will shrink the crank a bit and is a much more effective and safer method of easing installation without a threaded crank. |
*Use a sturdy block of wood like a 4-5" thick slice of a wooden fence post or 4x4- used grain-on, not across grain to help keep it from splitting- you'll be hitting it fairly hard in most cases, especially if no heat/cold is used. The wood is used to insulate the damper inner hub from the hammer blows. | *Use a sturdy block of wood like a 4-5" thick slice of a wooden fence post or 4x4- used grain-on, not across grain to help keep it from splitting- you'll be hitting it fairly hard in most cases, especially if no heat/cold is used.

{{warning|NEVER hit the damper on the outer ring- this can break the bond between the rubber and steel, making the damper useless. NEVER hit the damper metal to metal with a hammer. A damaged damper could fail, possibly causing personal injury and damage to the vehicle or even bystanders. Use gloves and '''[[Health and safety in the shop or garage#Eye protection|eye protection]]''' at a minimum.}} | {{warning|NEVER hit the damper on the outer ring- this can break the bond between the rubber and steel, making the damper useless.
