Step 2
Loop the straps around the shaft between the
flange bearings and the drums. (If chains are
used, then adequate protection must be placed
between the shaft and the chain to insure that the
shaft is not damaged by the chain.)
Note: Several types of straps or chains can be
used to lower the dyno into the pit.
Dynojet recommends using continuous
nylon loop straps. (Dyno weight = 6000
lbs. (2724 kg.).)
WARNING!! Do not loop straps around the middle of
the shaft between the two bearings as
the dyno will be unstable. Be sure that
the strap is at no less than a 60 degree
angle to the shaft.
