Description

JMI 10 Inch Pneumatic Large Wheels – Universal Style Wheeley Bars

Upgrade your JMI medium or large wheeley bar system with JMI 10 Inch Pneumatic Large Wheels – Universal Style Wheeley Bars.  Includes six large 10″ all-terrain pneumatic wheels and a tow handle to replace the standard 2-3/8″ hard-rubber wheels on medium or large sized universal wheeley bar set ups.  A dual inboard wheel design on the rear wheels maintains a narrow profile.  With these wheels, the Wheeley Bars will raise the mount approximately 3-1/4″ off the ground.

Note:  This item is available as an aftermarket upgrade to wheeley bars.  Allows the replacement of small wheels with large wheels if current wheels are attached with bolts (current manufacturing method) rather than rivets (very old manufacturing method).  With this aftermarket option, purchaser removes the original wheels and installs the 10″ wheels.  (JMI will not accept returns of used small wheels).

Note: If you simply wish to upgrade to the Wheeley Bars with 10″ wheels rather than 2-3/8″ wheels during purchase,  simply select your desired wheel size. This price offers a cost savings as the small wheels are essentially “traded in” toward the price of the larger wheels upon purchase.

What Size Wheels Should I Purchase?

The small 2-3/8″ hard-rubber wheels are good for flat hard surfaces with no cracks or grooves.

For hard surfaces, such as concrete sidewalks, with seams or cracks, the 5″ polyurethane wheels are best.

The large 10″ all-terrain pneumatic rubber-tire wheels are designed for field use on rough surfaces such as grass, dirt and gravel.  However, great care must be taken in maneuvering on these surfaces, particularly when wet, because the wheels may sink below the surface.

We do not recommend using Wheeley Bars on these surfaces under adverse conditions, especially if you have a very heavy telescope.

If you are purchasing the Large 10″ Pneumatic Wheel Upgrade for Large Size Universal Wheeley Bars or HEAVY DUTY Medium Size Universal Wheeley Bars purchased before October 2013, please let us know that you need the Long Mounting Bracket.  You can do so by entering, “LONG MOUNTING BRACKET” in the comments field in our shopping cart.  (If you are purchasing the upgrade at the same time you are purchasing the Wheeley Bars, you do NOT need to add this note.)

You can verify the need for the Long Mounting  Bracket by measuring the Threaded Leveling Screw Guide (Long Nut) which holds the leveling screw (see picture below).  Units built before October 2013 used a longer guide/nut which measures about 2-3/8″ and requires the Long Mounting Bracket.  Current guide/nut length (which does NOT require the longer bracket) is about 1-5/8″.
