SERVICE MANUALAssemble Power Divider Intermediate Case1.Assemble idler shaft bearings, bearing races andbearing spacer to idler gear. On models RA-351 and355, position the bearing spacers correctly to indexoil groove in rear spacer with oil passage in idlershaft (see Fig. 44).2.Position idler shaft in intermediate case so flats onrear of shaft will index with flats in differential carrier.3.Support front face of intermediate case and pressidler shaft into position.4.Install idler shaft end nut and washer. Tighten nut tospecified torque, Use flats on end of shaft to holdshaft from turning while tightening nut.5.Using a dial indicator, check end play of idler gear.End play should be within specified limits. (See"Specifications. ")6.If end play is not within specified limits, remove idlershaft and idler gear and change the bearing spacer.End play can be reduced by installing a thinnerspacer or increased by installing a thicker spacer.Determine spacer thickness with micrometer andmake new selection accordingly.Fig. 44. Cross Section Of Idler Shaft Installation1Lubricant Passage2Idler Gear3Spacer - End play controlledby thickness of this spacer4Thin spacer must beinstalled in this location5Idler ShaftWhile .000 end play for idler shaft is permissible, it isimportant that bearings not be loaded with sidethrust. Therefore, end play between specified limitsis desired.7.Assemble and install input gear.RA-341:a.Press bearing on input gear.b.Install bearing retaining nut. Clamp gear in viseand tighten retainer nut using SE-2247 wrench(Fig. 45). Tighten to specified torque. Usepunch to stake nut to gear end.c.Check input gear bearing end play with a dialindicator ,025-.076 mm (.001-.003"). Usebearing spacers as required to obtain correctend play.d.When end play is correct and retainer nut is finaltorqued, stake retainer nut at milled slot in inputgear.e.Position gear and bearing assembly inintermediate case. Support rear face of caseand press bearing into case bearing bore. Pressbearing to rear sufficiently to install bearing snapring.f.Install snap ring on bearing and press bearingand gear forward until snap ring seats firmlyagainst shoulder of case.RA-351and355:a.Using bearing spacer previously removed for atrial assembly, install bearings and cage on inputgear and clamp assembly in vise.b.Install bearing retaining nut and, using SE-2247bearing nut wrench, tighten to specified torque(Fig. 45). Use punch to stake nut to gear end.c.Install input gear bearings and bearing retainerinto intermediate case. Secure cage with six hexbolts. (See "Torque Chart") .Assemble Output Shaft1.Support output shaft bearing and press output shaftinto bearing.2.Tap bearing case of retainer over bearing andsecure with snap ring.3.Install seal in bearing case.4.Install flange and end nut.CTS-4044PRINTED IN UNITED STATES OF AMERICAPage 24
