2013 Bobcat T870 Wiper Wash Fluid Grommet Through Windshield Broken

[MikePhua]

The Bobcat T870 is a powerful tracked skid steer loader widely used in construction, agriculture, and land management. When critical systems such as the windshield wiper and wash fluid system fail, it can significantly affect the operator's visibility and overall productivity, especially in rainy or dusty conditions. Recently, many users have encountered an issue with the wiper wash fluid system on the 2013 Bobcat T870, where the grommet through the windshield is broken, leading to fluid leakage. This article will analyze the causes of this issue and provide solutions to fix it.
Problem Overview: Wiper Wash Fluid Grommet Broken
In the course of operating the Bobcat T870, some users have reported that the wiper wash fluid system is not functioning properly. Upon inspection, it was discovered that the issue often lies with the grommet that connects the wash fluid lines to the windshield. If the grommet is broken or improperly connected, it can lead to fluid leakage. This problem prevents the operator from using the wipers to clean the windshield, especially problematic in adverse weather conditions where visibility is crucial.
Possible Causes of the Issue

1. Rubber Grommet Aging
   The grommet used in the wiper wash fluid system is typically made from rubber. Over time, rubber can degrade, becoming brittle and cracking, which leads to leaks. This is especially true in harsh conditions, such as exposure to extreme temperatures, sunlight, or excessive moisture, all of which accelerate the aging process and increase the likelihood of the grommet breaking.
   
2. Loose or Improper Connection
   Another common issue is that the connection between the fluid lines and the grommet may become loose or improperly installed. Vibration during operation, or improper handling during repairs or maintenance, can lead to loose connections. This results in fluid leakage and the inability to use the wiper system properly.
   
3. Installation Defects or Damage
   If the grommet was not installed correctly during production or repair, or if the installation was done incorrectly, it may not be able to withstand the pressure from the fluid system. A poorly installed grommet will not provide a proper seal, causing fluid to leak and the wiper system to malfunction.
   

Solutions and Troubleshooting Steps

1. Replace the Broken Grommet
   The most straightforward solution is to replace the damaged grommet. Replacement grommets can be sourced from Bobcat authorized dealers or third-party suppliers. When replacing the grommet, ensure that the new part matches the specifications of the original one to maintain a proper seal and prevent further leakage.
   
2. Check and Replace Rubber Hoses
   In addition to the grommet, the rubber hoses themselves may have degraded over time. Inspect the entire length of the fluid lines for any cracks, abrasions, or signs of wear. If the hoses are worn or cracked, they should be replaced immediately to avoid leaks and ensure the wash fluid system works efficiently.
   
3. Inspect and Tighten Connections
   When installing a new grommet or fluid line, make sure that all connections are properly tightened. Loose connections can lead to fluid leakage and cause the system to fail. During regular maintenance, check these connection points to ensure they remain secure, preventing the issue of loose fittings.
   
4. Regular Maintenance and Inspection
   To prevent similar issues in the future, it’s important to regularly maintain and inspect the fluid system on the Bobcat T870. Routinely check the grommets, hoses, and connections for signs of wear or damage. Keeping the system clean and free from dirt or contaminants will help it function smoothly and extend its lifespan.
   

Conclusion
The broken grommet issue with the wiper wash fluid system on the 2013 Bobcat T870 is a common yet easily fixable problem. By replacing the damaged grommet, checking and replacing worn hoses, ensuring tight connections, and conducting regular maintenance, users can restore the functionality of the windshield wiper system. Regular upkeep not only helps improve operational efficiency but also reduces downtime, extends the equipment’s lifespan, and minimizes repair costs.
