People who have a GBH 5-40 DE all models have the same problem in the position of the gears between pos 47 and 51 there is 1 ring pos 102 i was wondering because i have earlier problems with the BOSCH drawings of the model GBH4-32 DFR because of the mis positioning and the correction and again they have changed the drawing back to the wrong position of rings 102 . of model gbh4-32dfr but now they have placed a little technical story on their site in the mservice drawing because of tolerance between the rings together ,that wakes me up because i have yesterday 19-07 serviced a gbh5-40DE and there where 2 rings 102 to find but the drawing tels me there is only one used ???? i have serviced it with the 2 rings and it was after the service again like new also it sounds good , but before i have serviced earlier that rotary hammers the hammers are good , but please take care of the service drawings there are errors and when you think i give it a try to send them an advise tacitly without even one Thanksgiving they had the drawing to my example of a provisional plan changed, but have them later changed the drawing back like the drawing before ???? and why ??? and for shure again wrong again placed the rings pos 102 both in the wrong position order of the position place because the BOSCH people have the last word.
The mentality well-meaning people to be treated in this way, its only Bosch do so.
Dewalt Stanley react properly, adjust the fly off errors in drawings, inbetween 1 hour they corrected errors on their site in England but also including brands like Festool, or Milwaukee, or Panasonic or any other arbitrary mark nothing do they wrong and are happy with solving some errors, only not Bosch the only one Bosch is in the class drills cute models but there are a lot of ailments in the budged range also the blue series not only the green colored equipment .
NOw its time to let see what the problems where because of the drawings first drawing is the first wrong drawing of the gbh4-32dfr because of the rings pos 47 and 102 in the middle of the drawing by the black arrow pay attention :
And now the drawing that i have provisionally updated to Bosch almost a year ago pay attention
Now the first and only correct drawing made by Bosch out of this drawing a few months ago pay attention extra and made a copy because its not anymore to find.!! here it comes
And after a long time and that was yesterday 19-7 i was searching because of a very strange fall by service a bosch 5-40 i watched the drawing again of the gbh4-32dfr and wtf have they do !!!!! unbelieveable i saw the light again the old wrong drawing with a special attention hihihii PAY ATTENTION this drawing is for shure again incorrect wrong positioned post 47 and both 102 here comes the latest drawing of the GBH4-32DFR
THere are no sites to find who have the correct drawing anymore but why i looked back because the gbh5-40 DE i was serving yesterday has 2 rings 102 in it and i saw this story about the tolerance and i was wondering why some forest rotary hammers sometimes quickly had a sub sound, BECAUSE OF 1 missing ring 102 in most models and the tolerance is to Great Because Of The Great extra load on the drive.
When the rotary hammers from Bosch where the tolerance rings are present, there are always two rings are present !! and or between 0.08 and 0.22 mm, that tolerance may be between ring 47 and ring 51 will wear differently strange because of the drive of the teeth
