TORX 
A TORX BN. 8189 screw set is used with engines in the 2011 series. This system was 
chosen because of the many advantages it offers: 
•  Outstanding accessibility to bolts 
•  High load transfer when loosening and tightening 
•  Almost impossible for the socket to slide off or break, thereby practically ruling 
out the risk of injury. 
TORX tools can be ordered from DEUTZ. 
V-belt tension gage 
The V-belt tension gauge can be obtained under order number 8115 from DEUTZ.
