Initially, they took it down off of its plinth and disassembled it, taking the bells down from the frame.
ABE Electrician Nathan Hawtree said they were in charge of the electrical work and of refurbishing the bells once MTR had taken them off the frame.
"We took it because a lot of electrical work had to be done on the bells themselves," he said.
This included a complete replacement of all the solenoids and hammer mechanisms that ring the Carillon's bells.
This part of the repairs took months as the replacement hammers were manufactured by the company that made the originals, Dutch company Petit & Fritsen, and took two months to make, plus another month to be shipped here.
While the work on the bells was being completed, the frame was sent away to Spectrum Powder Coating in Auckland to be refinished.
Hawtree said ABE refurbished the bells and refitted them to the frame once it got back from being powder-coated.
Hawtree said it then took a day of tuning to get the bells to play the right notes, which involved little tweaks to each bell to get them on-song.
"[It involved] a lot of climbing up of ladders and adjusting the hammers so we got a nice tone out of the bells."
Once the frame was reassembled and reunited with its bells, MTR mounted it back on its plinth.
The Carillon is now chiming once again and will play each hour from 6am to 6pm daily, automatically cycling through 12 different tunes.
Hawtree said it felt good to have the project completed and the bells playing once more.
"It's always good to get something like that up and running," he said.
