Mettler-Toledo DV90 replacement burette drives for DL50/70 series titrators.

Description

Mettler-Toledo DV90 burette drives.
Interchangeable with and fits all Mettler-Toledo DL50/53/55/58 and DL70/77 series titrators.
Extend the life of your Mettler-Toledo DL series titrator by replacing the burette drive if it's failed at a fraction of the cost of buying a new titrator.  All units have been serviced and calibrated by Mettler-Toledo factory service while they were in use.  No missing teeth on the gears.  All drives meet or exceed Mettler-Toledo factory tolerances for DV90 burette drives.
There is some small staining and scuff marks from general use on the housings.
The items pictured are what is for sale.  These items are used but are in very good working order.
As a note, if you are replacing the burette drive in your DL70 series titrator, you must turn the titrator onto it's side.  Remove the 4 screws holding the base plate on.  Then unhook the DV90's  connnection cable from the main board and the drive will slide out of the top of the housing.
If you are replacing the drive in your DL50 series titrator you can lift the drive out of the top of the housing after unscrewing the fastening screw on the back of the drive.
In either case, ALWAYS make sure the unit is powered OFF and unplugged before disconnecting or installing drives.
Thank you for you interest.
