How to Replace Hilti TE22 chuck
You put the two flat sides on the end of the cap nut and lock them in a vice. You then put a wrench on the back side of the chuck which also has two flat sides. with the cap nut locked in a vise take the wrench and turn the retaining sleeve which has the two flat sides counterclockwise to break the cap nut loose. When it turns freely take the chuck out of the vise and turn the cap nut off. You then push the ribbed locking sleeve down to access an o-ring. You pull that off and it releases the locking sleeve and two roller bearings. You then pull off the retaining slv with the two flat sides and release the other two roller bearings. the chuck will then just pull off the shaftHope this helps
My hilti te-75 drills but is not hammering
Have seen this problem with some 'none' HILTI bits which do not fit correctly into the SDS chuck.
Tends to be with larger drill bits which have a wider shank than the SDS connector, the wider shank hits the end of the drill nose which stops the end of the drill bit contacting with the internal hammer.
Solution is to purchase original bits from Hilti. If you have OEM bits and chisel it will be another problem. Hope this helps.
