Jack mounting and jack adapters. The pictures below shows a Tronair jack, some jacks may not have the feature of one inch mounting. For alternate mounting see the pictures lower on the page using our "over the top" adapter.
Remove the jack cup from the top of the jack ram
Note the one inch hole in the top of the jack ram.
One inch studs are supplied with all our kits, this is the preferred mounting method
Screw the stud into the bottom of the transducer load cell, make sure the stud threads all the way into the cell with no "air gap" between the cell and the stud.
The cell is now mounted, make sure that there are no "air gaps" between the cell and the top of the jack ram while jacking and under load.
If your jack does not have the one inch hole or removable cup, check the bottom side of the ram for the hole. Pull the ram tube out of the threaded cylinder and check, some jacks will have the hole on the bottom.
Here is our adapter located on top of the jack ram, always count the threads on each bolt to ensure centering. Faliure to properly center the adapter will result in injury or damage as the cell can be forced off center of the ram. Only qualified and trained personnel shall use our adapters.
Once the adapter is secured and torqued to 100 in/lbs the cell can be installed in the one inch hole using the existing mounting stud supplied with our kits.
Over the top of the ram adapters. Some jacks do not have the one inch hole you will have to use an "Over the Top" adapter. Shown here is the Meyer Hydraulics jack with our adapter fitted. These adapters are not included with our kits and are available as an option, they are available in two sizes to fit the small tube and large tube for use on the Meyer Hydraulics jacks as well as others.
Meyers Hydraulics jacks do not have the one inch hole, here is shown a standard Meyers with jack point dimple. Note the welded area, older kits will have an adapter as shown below that will not properly grip this jack ram.

Machined from 4140 steel, the adapter series are avaialble in a 3.5 inch and 5 inch size. Shown here is the 5 inch on top of a Meyers Hydraulics jack. If your jacks do not have the one inch mounting hole for load cells, that is not an issue, with our adapters we can interface with most jack ram types..
Warning: The use of over the top adapter can be dangerous, only trained and qualified personnel should attempt to use this type of adapter. This type of adapter requires extreme attention to detail, centering and placement as well as monitoring the cell and adapter for movement. Failure to properly mount and use this adapter will result in damage to the aircraft or injury to personnel.
