•  The  extension bridge piece 4794-2  pro-
vides an even larger area of application.
•  Replace  the  short  standard  bridge  piece 
on  4794-1  with  the  extension  bridge  piece 
4794-2.  This  enables  an  extended  dis-
tance between the fixing arms for camshaft 
sprockets/injection pump sprockets located 
further apart from each other.
PART 2: 4794-3/3
Locking device for
single camshaft engines and
V engines with 2 camshafts
Illustration
• Locking device 4794-3/3 is suited for
single camshaft engines and V engines
with 2 camshafts.
•  For fixing the crankshaft sprocket into tim-
ing position during timing belt replacement 
and  fixing  the  injection  pump  sprocket  in 
various diesel engines.
CAUTION: Suitable for use with camshaft
sprockets/injection pump sprockets with
20 mm - 35 mm width.

4794-3/3:
•  Locking  device  4794-3/3  keeps  the  cam-
shaft  in  their  timing  position  to  ensure  the 
engine timing is retained during timing belt 
replacements.
•  4794-3/3  is  of  use  primary  for  aligning 
the  timing  belt  markings  in  V  engines  and 
engine  designs  in  which  the  camshaft 
sprockets are far away from each other.
•  Thanks  to  its  compact  design,  the  locking 
device 4794-3/3 is also suited for engines in 
which there is only a small amount of space 
in  the  engine  compartment  due  to  vehicle 
design.
Maintenance work on engines must be carried out only by experienced mechanics.

Application:
•  4794-3/3 consists of 3 components – the
basic unit 4794-31 (assembled with the
single parts A, B, C and D), a short lock-
ing pin 4794-32 and a long locking pin
4794-33.
A = Main body
B = Front tensioning jaw
C = Fixing knob
D = Adjusting screw (parallel position)
E = 4794-32
F = 4594-33
•  The basic unit 4794-31 is assembled loosely 
and  secured  onto  the  camshaft  sprocket 
/  injection  pump  sprocket.  The  main  body 
A  must  be  located  on  the  back  side  of 
the  camshaft  sprocket  /  injection  pump 
sprocket,  the  front  tensioning  jaw  B  at  the 
front.  By  tightening  the  locking  knob  C, 
the basic unit 4794-31 is securely fastened 
into  position.  Select  the  short  4794-32  or 
long  4794-33  locking  pin  according  to  the 
distance  of  the  basic  unit  to  the  engine 
block,  and  screw  this  through  the  basic 
unit  so  that  it  is  firmly  pressed  against  the 
engine  block.  The  locking  device  4794-3/3 
and the camshaft sprocket / injection pump 
sprocket are now fixed into position. 
Illustration
IMPORTANT:
The adjusting screw D ensures that 
when fixing the locking device 4794-
3/3 into position, the main body A and 
the front tensioning jaw B remain parallel to
each other.
Always keep locking pins
well lubricated.
