ELEVATING AND TRAVERSING MECHANISMS
 RN TO TRA E ELEVATING GEAR ARC-- \1
 OR ELE\ATE- B, MN.RaMNK Gears chipped, worn,
 AND BT POWER AT TrE rusty, blocked up with
 S~ E TIMtE. brush.

 ELEVATING FINAL DRIVE
 OIL I -Oil level low (should
 LovuEcL be level with bottom of
 filler hole); wrong lube;
 seepage.
 TRAVERSE FINAL DRIVE
 -Oil level off (should be "kev-
 3%-in from top of filler
 hole); wrong lube; seep
 age.

 (Like your LO says both of these final drive
 assemblies should be checked weekly they gel
 OES only. OES has a neutral color, so if you notice
 1 any reddish color in there you l know you're
 getting seepage from the hydraulic system Recoil
 oil is red This seepage will tell you that the oil
 seal in the case is shol--another lob for your
 Support guys.)

 traverse, doublecheck the hydraulic system for oil line or connector leaks

pport to double check these check out OK, it could be the hydraulic motor's on the bum. If the
and elevating clutches' elevation's on the jerky side, doublecheck to see that both equilibrators
ents. are adjusted right.)
