How can I open Hilti te-72, to see what is wrong with hammer?
I oppend at the back, but I can't open the front side.
At the back fall off some broken pieces, form the middle.
Do not put it in hammer mode and try to unscrew the chuck! This will break the housing internally. To remove the chuck you will have to put a chisel in the chuck. Lock that chisel in a big vice. You will then have to put a pipe wrench on the chuck to unscrew it. It is regular threads but there will be loctite on it. Once that is off your will have a spring and two roller bearings to remove before you can slide the bell off. You will then have 8 5MM screws to remove. This will remove the chuck. You will then have a snap ring to remove. After that you can remove the whole cylinder assy. More then likely your connecting rod is broken.
I thought hilti had life tim guaranteeplease chck this out first bfore stripping, please leave feedback
The chuck should unscrew on the front of the machine. Put it in hammer only mode and use a pipe wrench to remove chuck then there will be a snap ring to remove further in the tool. I suspect that the conrod that drives the piston has broken as that recently happened with my te 72.
