Pros and Cons of Buying Ski-Doo 420985635 Elko Piston for a 1972 TNT 640 with Standard Magnetic Ignition

The Ski-Doo 420985635 Elko piston is a replacement piston specifically designed for the 1972 TNT 640 snowmobile model with a standard magnetic ignition system. While purchasing a new piston may not seem like an exciting decision, its impact on your snowmobile's performance can be substantial. In this analysis, we will examine the pros and cons of buying a Elko piston.

1. Improved performance: A new OEM (original equipment manufacturer) piston can positively affect your snowmobile's engine performance by ensuring proper sealing and reducing engine wear.

2. Reliability: Given that the piston is a Warranty/NOS (new old stock) item, you can have peace of mind knowing that it has not been previously used, lowering the risk of any potential engine problems.

3. Compatibility: Since it is an OEM part manufactured specifically for your snowmobile model and piston size, it fits perfectly and integrates seamlessly with your engine components.

4. Ensures proper clearance: The Elko piston has been designed for the 1972 TNT 640, guaranteeing proper clearance between the piston and the engine housing.

5. Backed by the manufacturer: If this part fails within the specified warranty period, you can contact Ski-Doo for a repair or replacement.

1. Cost: The Ski-Doo Elko piston can be an expensive investment, especially when compared to re-using or rebuilding the existing one. However, it provides the peace of mind that comes with a new, authentic OEM part.

2. Longer downtime: With most snowmobiling taking place during the winter months, the piston replacement could result in a longer period of 'off-season' downtime.

The decision to invest in the Ski-Doo 420985635 Elko piston for your 1972 TNT 640 snowmobile depends on several factors, including your budget, your tolerance for downtime during the off-season, and your desire for a new, reliable engine component. Considering the potential improvement in performance, reliability, compatibility, proper clearance, and warranty coverage, a new OEM Elko piston may provide more benefits in the long run. However, it is essential to weigh these advantages against the cost of the part and potential off-season downtime.

Should you have the financial means and a desire for a new, reliable engine component, we recommend investing in the Elko piston for your 1972 TNT 640 snowmobile. If your budget is tight or you prefer rebuilding components, you may choose to explore alternative options, such as purchasing a used or rebuilt piston. Always remember that each decision comes with its unique advantages and disadvantages, so thoroughly consider all factors before making a choice.
