Fan Towers
Need GIA
.
The fan towers in yOur hOwitzer need a fan let-
ter because they dO a gOOd jOb Under heavy Odds.
What they need Even mOre is a semi±annual lubing with grease, aircraft and
instrument (GIA) the way it says in NOte 39 On page 18 Of yOur L09²235³²217±
12N ´Un 78). (The reference numbers are turned arOund in the nOte. The lUbe
fitting is 55 and the relµef fitting is 54¶)
The fans sOmetimes get shOrted On lube because crewmen have tO take OFf
the access cOver tO get tO the fittings, and that's a little trOUble. As a result OF nOt
getting lubed, the fans, gear shaft and gears fail.
·COUrse, there¸s a chance that they've never B¹eH altered tO take the greºse
fittin» and pressUre relief fitting.
In that c¼se, yOUr dir¹ct sUppOrt can dO the jOb fOr yOU the next time the
pOw¹r pack is remOved. InstrUcti½ns are On page 3±78 Of TM43±³¾43 (JUn 77),
