Look for this new feature to appear every week or two here on the Vermont Local Roads Blog. We will share recent questions that circuit rider Steve Jerome received from around the state, and work to answer the questions the best that we can. It is our hope that readers will be able to ask any follow-up questions to Steve here, so we can act accordingly and make sure every answer is clear.
The question of whether it is better to use hand-lever, air-powered or battery operated grease guns came up at the Vermont Local Roads tractor-mower workshops last week in Marshfield and Thetford. Steve was able to follow-up and found at machinerylubrication.com that: “a high power grease gun can deliver pressure up to 15,000 psi. Most bearing seals will rarely handle more than 500 psi. A grease gun in the hands of an untrained technician can compromise the bearing seal’s and lead to early failure. The compromised seal invites dirt or other foreign materials as well as over lubrication due to little or no back pressure.” Hand powered grease guns can put out up to 2,000 psi, Steve found out after consulting a grease gun manufacturer’s specifications. Steve cautions that each individual garage should ask the sales representative for the machinery or the equipment that they buy which type of greasing should be performed and which greasing tool is the best fit.

A question also came up about recycling HDPE culverts. Vermont Local Roads is looking to find the answer through Hancor, and ADS. It appears that recycling will be possible, but we are still awaiting further details. If you have any questions please contact Steve at 800-462-6555 (office phone), or at 802-272-0061 (his cell phone.) Check back for more information regarding possible HDPE recycling here, and in upcoming Vermont Local Roads Publications.
