Figure 6-21. Oil Tank Removed
6-3.1. Removal of Oil Tank 4.5kW (KT17 Series I only)
1. Drain oil from oil tank assembly.
2. Detach nut from eyebolt. Remove the bolt attaching the
oil tank to engine leg. Detach ventilation line (Figure 6-20).
3. Pull the tank off, making sure it is removed squarely
(Figure 6-21).
4. Oil Level Switch Replacement. (If the oil level switch
does not need replacement, omit Step 4.)
a. Remove oil tank cover by removing six screws. Be
careful not to damage gasket surface when prying
apart.
b. Remove switch at coupling connection. It will be
necessary to cutoff eyelet terminal and insulink to
remove switch.
c. Apply pipe thread compound to new switch, slide
leads through insulator sleeve and thread switch into
coupling. Tighten switch so that distance between
bottom of switch and inside of cover is 3.0 in. (76.2mm).
See Figure 6-22.

d. With gasket surfaces clean, install oil tank cover
using a new gasket. Torque bolts to 70 in/lbs. (7.9Nm)
using torque sequence shown in Figure 6-23.
NOTE
Cut one wire from switch so that it reaches
screw shown in Figure 6-23, strip 250 in.
(6.4mm) of insulation and crimp-on l/4" eye-
let term inal. Place terminal between lockwasher
and cover.
e. Plug end of ventilation fitting. Below compressed air,
about 30 psi (207kPa), into oil tank bore and check for
leaks at gasket surfaces, switch connection and ventila-
tion fitting using a soap solution. Repair any leaks.
CAUTION
Any air leak in the ventilation line system could
cause the engine oil to be drawn from the reser-
voir into the crankcase, resulting in engine blow-
by and a low oil level shutdown.
f. Cut the other wire from switch so that it reaches
#I2
(purple) lead, strip .250 in. (6.4mm) of insulation and
connect together using an insulink.
