Question about Hilti TE 7-C 120V Rotary Hammer Drill
To seperate the motor housing from the gear housing you need to loosen up the two 5mm allen head bolts at the base of the handle. At the top of the handle you will see a hole. there is a 5mm allen head bolt that you will access through that hole. Back that screw all the way out. The lay the tool with the gear housing down and the motor up. Remove the 5mm bolts holding the two housings together. Tapping with a soft blow hammer you should be able to seperate the housings. Be carefull that you don't lose the lube out of the housing.
Here are instructions on removing the front end.
If yours is a metal housing here is how you disassenble the front end.First you need to put a flat bladed chisel in the chuck. Then lock the chisel in a vise. Next you put a pipe wrench on the chuck cap nut. That is the piece on the end of the chuck. Using a cheater bar turn the nut off counter clock wise. You then can remove your chisel, the cap nut, an oring and the locking sleeve with two rollers. This will expose the chuck that is held in place with 8 5mm allen screws. After that you have a large snap ring to remove before pulling out the rest of the front end assy
