NO-LOAD TEST-With brakes set at maxi-
mum and shift in neutral, run engine until
normal operating temperature is reached.
Gradually press on the accelerator until its
limit is reached.

 Engine speed will generally go over 2,450 RPM
 for a second and then stabilize at 2,450. If the
 governor repeatedly cuts in and out or surges at
 this speed, get your support maintenance to make
 adjustments. If the governor won't work, speed
 could go out of control. Be prepared to shut down
 so speed will not go over 2,450 RPM for more
 than 2-3 seconds.


CAB RACE RING-Too much lube on the race
ring can cause vehicle deadline. Open the
inspection door and make sure it really needs
lube before you pull a pipe plug and tem-
porarily replace it with a grease tilting.

TRAVERSE MECHANISM-Grease and dirt
tend to pile up near the traverse mechanism
pinion gears. Open the access plates and
clean as needed.


 FUEL -ArS CRACKED?-Your support can
 repair 'em now the way it shows on pages
 63-65 of TM 9-2350-217-34/1 (Jan 65). They'll
 have the right repair kit-FSN 2910-078-
 4065, on page 25 of the -25P/1 TM.

 -ilh'wi.iii TUBES (M109 vehicles with
Serial No. 1123 and up)-With the new el-
evating cylinder the hydraulic tubes tend to
break. An MWO for a damper bracket is in THEY'F
the works but for now loosen all 4 tube NOT
clamps. After letting the tubes get in a relax- PASSEN'
ed position, retighten the clamps and wind STRAP'
several turns of green tape around the tubes
and the cylinder. These tubes are not sub-
way straps. No. 1 cannoneer, 'nuff said?


HYDPALUIi: F'OWEP PACK The retaining
clamp FSN 5340-0816707 can loosen which
will allow too much vibration which may rup-
ture the lines. Getting the clamp too tight
can be lust as bad. So ask your mechanic to
tighten the adjusting nut with a .002 feeler
gage under it so tight he can not pull the
feeler gage loose. Then he will back off
enough to get the gage out after which he
will retighten 1-'i to 1-'2 turns.


 SLINGS AND THINGS
POWER PLANT SLING Get the right
one FSN 4910-084-0790 (10913779)
-and make sure MWO 9-2350-217-
20/5 (Nov 65) has been applied. The
MWO offsets the cross bars so they're
shorter on the left side.
 (On some of the slings the hooks are
too large for the transmission lifting
brackets -so widen the holes, at the
bottom, not at the top, as this would
weaken the bracket.)
