Try turning again clockwise with a little more pressure. If the brakes were worn badly the piston is just stuck from being adjusted out so far.

SOURCE: hilti te-72 hammer failure

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.

Hi . The solution offered by rowdy (pull the trigger and hold it until light goes out) will only work on older machines, the newer machines have more complex electronics that need reseting using an optical reader which plugs into a PC , you will also need the Hilti ODA Software. this is not available to the general public. you may have to send it back to hilti for service and reset. this is free if the machine is less than 2 years old.

I have a Hilti TP800 with a worn cord. Any tips on getting the two nuts off so the handle can be taken apart....


Just take a flat head screw driver and put it in on one side of the slot. Tap on the screwdriver in a counter clockwise motion. It usually does not take much to get the nut started after that you just spin the nut off. the rod will then just slide out the other side.

We have a Hilti TE72 Hammer Drill.... We have taken it to fix but they say they can't find parts... We think it is the piston and a rubber gasket that goes with the piston.... Do you have this?


Parts are no longer available for the TE72. You may find some used parts on EBAY. If the tool is not hammering it would need more than the piston and oring that goes on the pistion. Without all the proper seals and gaskets I would not even attempt to repair. If you do attempt to repair it do not put more than 70cc of lube in the drill. Too much oil will distroy the gears.

1 Answer

Hilti TE 17. Hammer doesnt work. Rotary does.


Most likely the O-rings are worn - tool has no compression to move the hammers inside.
Less likely: the connecting rod for the piston is broken so piston isn't moving - or 2nd hammer is broken into pieces.
I would open it up & check the orings first

I have a hilti TP800 that will not hammer. no polunging action for the chisels


TP800 are that takes me back. right hear we go...
as over people have sugested remove the 4 screws and the black plastic cap from the top of the machine. you should be able to see the con rod and the crank gear, and in front of the crank gear you should see the small gear which is the top of thr armature, you may have to scoop out some grease in order to see it. Check that the con rod is not broken. earlier machines had aluminium cod rods but the later models have plastic ones which were prone to breaking. this isn't to say that the aluminium ones never broke because they did and wow what a mess may made when they did. if your con rod looks ok, try this... keep your hands clear of the open gears, and put some glasses on. turn the machine on and make sure that the crank is turning. look at the small gear on the armature to see is it is wobbly. the small roller bearing at the top of the armature use to callapse causing them to wobble. this would strip both the gears. a good sign of this is metalic parlicles in the grease. this fault is very expensive as you will have to replace the armature, bearing, seal, and the crankshaft. ouch...BUT DONT DESPARE. if this looks ok, it must be the piston rings these are cheap, fairly easy to change and available, as they are still used on more current models. the part number for these piston rings (o-rings) is 13772. want to know how to change them?.. read on...The hardest part is removing the chuck as you must remove the retaining clip at the tip of the chuck. hilti make a special tool for this, but it is possible with a good set of circlip pliers, 2 flat screw drivers and 4 hands. top tip...Remove the rear handle assembly, just remove the 4 screws and pull it off, now the machine can be stood upright on a workbench. Wear safaty goggles and put a chisel in the chuck, this will help you not to loose the clip when it flies across the workshop, I hate it when that happens. once you have the clip off its easy from now on. and don't worry, there is an easy way to get it back on. ok, the clip is off. remove the washer and the plastic chuck cover. remove the circlip, remove the chuck sleeves, dont loose the 6 balls or the roller. now there is another large circlip which holds on the black plastic cover. remove them both. now you can see the 6 bolts which hold the machine together. remove them. remove the chuck.you will see a large o-ring around the cylinder, remove it. Now with a screw driver carfully split the cylinder at the point where the o-ring was sitting. carefully pull out the inner cylinder. dont loose the small plastic balls. if they fall out dont worry. put them to one side. inside this cylinder you will find the follower piston, just tap the clyinder on the workbench and it will fall out. replace the o-ring, smaer with grease and replace. The drive piston is probably still inside the red casing. Simply pull the con rod off the crank and tip it out of the casing. on early models this piston had 2 seals. 1 teflon ring over a green rubber O-Ring. on later models these were replaced with an o-ring, the same as the follower piston, the earier type may not be available in which case you may have to replace the pison as well in order to fit the newer o-ring system. once the seals have been replaced, smear with grease. place the piton inside the cylinder just far enough so the conector pin cant fall out of the drive piston. Replace the plastic balls into the detents in the cylinder. use grease to hold them in place. Replace the cylinder into the caseing but make sure that the cut out at the end of the cylider is facing down. This is where the armature gear sits. as you push the cylinder in ensure that the con rod is hooked onto the crankshaft. reassemble in reverse order. use grease to hold the chuck balls and roller in place. dont fit the rear handle yet..now for that clip that caused all the pain at the start of the job. PuT YOUR GOGGLES ON. stand the machine upright on the workbench and get somone to hold it. place the clip on top of the chuck body tube. get a block of wood and place it on top of the ring, and hit it with a hammer. this will knock the ring on 80% of the way, now tap it on with the hammer. refit the rear handle. your done,,,if you removed all the grease replace with a similar type. 70 grams (3 oz) in the crank case under that black plastic cover..
Well I hope that helps, its not as bad as it sounds.
good luck.
please leave feedback .
if you have any more questions please email me.
if you want a parts diagram i can email you a drawing of a TE804 which is virtually the same machine with a slightly different chuck.
