A defect to my Hilti Te-6 electric drill makes it only work in one way direction. Rotation is the apposite way against the clock??. In this direction i'm not able to use it for any purpose. What can i do? Or is it a mechanical problem what i can fix myself. Now and than it's working properly, so dust/dirt might be the problem. Thinking about getting a new switch but there might be a cheaper solution. Thanks 4 help With kind regard Hans

what I would do if you have a fax machine is call 1-800-879-8000 and request a schematic on this tool first. Some of their products are not that easy to disassemble. I never have worked on the TE-60 but have on some of their other products and they are all different. Hope this helps

SOURCE: HOW DO YOU DISASSEMBLE THE GEAR BOX SECTION OF A

Its not that hard. however I have been working with hiltis for 22 years. once you have removed the handl assembly, remove the 4 screws which hold the motor unit to the gearbox. you will lose oil but dont worry. this will expose the drive gears. the smaller one is the crank drive or the hammer action. the larger one is the clutch assembly for the drilling action. remove the smaller of the 2 gears from its shaft by removing the circlip. you should now be able to see the circlip which holds the crankshaft into the gear housing. remove the circlip and pull out th crankshaft, this will be a tight fit so you may have to hold the shaft in a vice and carefully fit the gear housing using a rubber mallet. now you have to remove the chuck. 1st remove the rubber cap by getting a large flat screwdrivver behind it. using circlip pliers, remove the c-clip (wear safety goggles) the rest of the chuck parts should them be able to be removed with easy. you should now be able to see a large circlip, remove it. you can now remove the oil seal. this will need replacing as it is hard to remove without damage. part number 206105. under the seal there is another circlip. once this is removed you will be able the remove the guts of the gear box. again you may have to put the chuck tube in a vice and tap the gearbox housing with a rubber mallet. again you will loose oil. to reassembly just reverse the prosess. remove the oil filler cap to ensure that the crank shaft locates on the con rod . once reassembled replace the oil. 40cc only. transmission oil is good and the closest match you will get to the origional. for more info send me an email.

ps before you start make sure that parts are still available for this machine asit is quit old (no offence).
The piston rings (17955) are but i dont know about the oil seal.
you car get the seal from any car parts shop. it is a double lipped seal 35mm x 62mm x 10mm.

I hope this has helped. please leave feed back.
email me if you want a diagram sent.

Happy xmas

SOURCE: I have a Hilti TE 905 AVR the service light came

If you have the old type TE905, which is the one with the square type handle at the back, the service light will come on for 2 reasons. Either there is a tight bearing which will increase the amount of current used to work the machine. Or more common the carbon brushes need replacing. To reset the light, simply cure the problem.

If you have the newer type TE905 with the large “D” Type handle at the back. It gets a bit more complicated. The service light will come on for the same reasons as mentioned above, but it will also come on after 200 hours of use. It will continue to work for another 50 hours with the light on, then it will shut down completely. This is to ensure that it gets regular service. Once serviced or repaired, it will require resetting. To do this you with need a Hilti optical interface, a PC, and Hilti ODA Software. This is not available to the general public. If your Hilti is less Than 2 years old, call Hilti. They will pick it up, repair it, and send it back to you in 3 working days FREE OF CHARGE. If it is older than 2 years there will be a charge for the repairs.
I hope this helped you. Please leave feedback

SOURCE: how to open hilti 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
