pi222002 rev 2.06 whitedriveproducts service instructions for the rs [200 201 series motors for use with seal kits 200222001 200222002 dimensions mm [in important note the rs200/201 series motors depend on the correct orientation of parts as well as correct internal timing for proper motor operation before disassembling the motor it is highly recommended that paint or a marker be used to make a v shaped set of lines from the endcover to the housing this will aid in reassembling the motor components properly it is also important that the steps involving internal parts timing be followed carefully to insure proper motor operation a remove all shaft related components from shaft 21 i.e keys wire rings nuts to aid in reassembly of the motor make a v shaped set of lines from the endcover 16 to the housing using either paint or a marker with shaft facing down secure motor in vise by clamping on to housing 19 b loosen and remove four bolts 18 holding motor assembly together remove endcover 16 remove body seal 8 and discard seal remove rotor assembly 14 and wear plate 13 remove body seals 8 from rotor assembly 14 and housing 19 and discard seals remove drive link pin 15 and drive link 12 from motor and lay aside c gently tap shaft 21 upward through housing 19 and remove through rear of housing turn shaft over and remove cooling plug 20 remove housing 19 from vise and turn over pry dust seal 1 from housing push the seal carrier 9 thrust washer 10 and thrust bearing 11 down and remove through rear of housing note when removing items 9-11 care should be taken so that housing bore is not scratched or nicked if a new seal carrier and thrust washer is included in kit old items may be discarded if not carefully pry shaft seal 7 teflon backup seal 6 and metal backup shim 5 from seal carrier 9 and discard items 5-7 lay seal carrier 9 aside remove wire ring 2 metal backup shim 3 and high pressure seal 4 from inner bore groove of housing with a small screwdriver and discard items at this point all parts should be cleaned in an oil-based solvent and dried using compressed air for safety observe all osha safety guidelines all new seals should be lightly coated in clean oil prior to installation d place shaft 21 on a clean flat surface with output end facing up place thrust bearing 11 then thrust washer 10 on shaft install shaft seal 7 down onto shaft 21 making sure that lip on seal faces down see figure 1 for correct seal orientation install the teflon backup seal 6 onto the shaft 21 with the flat side up and the seal lip facing the shaft seal 7 place the metal backup shim 5 onto the shaft and against the teflon backup seal 6 place the seal carrier 9 onto the shaft large end down and carefully press the seal carrier 9 down onto the seal assembly using an arbor press and sleeve to compress the seals into the carrier e install high pressure seal 4 into groove in housing install metal backup shim 3 against high pressure seal 4 in groove in housing bore by squeezing the shim 3 between thumb and forefinger to bow shim bow in the shim should be in the shape of a hill and not a valley for easier installation while maintaining bow in shim start the shim into the groove and use a small screwdriver to push the shim into groove install wire ring 2 into the groove making sure that the ends are butted rs 200/201 shaft/drive link timing procedures note to return the rs series motors to proper operation the rotation code of the motor must be known the rotation code of the motor is 200standard 201reverse timed the first 3 digits of the model code if the rotational code is not known motors that are to have the shafts turning clockwise as viewed from the shaft end should be timed using the 200 series and motors that are to have the shafts turning counterclockwise as viewed from shaft end should be timed using the 201 series f turn shaft 21 over so that output end of shaft faces down install cooling plug 20 down into shaft 21 making sure large o.d end of cooling plug 20 faces up lower drive link 12 into shaft making sure that timing mark end of drive link faces up and that the timing mark on the end of the drive link 12 is aligned with one of the through holes in the shaft 21 when splines contact each other slowly rotate drive link 12 counterclockwise for a 200 series or clockwise for a 201 series motor until drive link splines engage with those on shaft 21 g turn housing 19 over so that pilot of housing faces down and secure housing 19 in vise without disturbing seal carrier assembly 9 or drive link 12 carefully lower shaft assembly into housing to seat seal carrier 9 against wire ring 2 gently tap drive link 12 down until end of shaft 21 is nearly flush with rear surface of housing h place a body seal 8 in the groove in the rear surface of the housing 19 using alignment marks as a guide place wear plate 13 on housing making sure that notch in wear plate 13 is aligned with port side of housing 20 see figure 2 i place a body seal 8 in the groove in the face of the rotor assembly 14 lower rotor 14 onto drive link 12 making sure that timing mark on drive link is aligned with a peak on the rotor 14 see figure 3 once splines are engaged rotate rotor 14 so that notch on rotor is aligned with notch on wear plate 13 and ports on housing 19 see figure 2 insert drive link pin 15 into end of drive link 12 making sure that concave end faces up white drive products inc · p.o box 1127 · hopkinsville ky 42241 · phone 270.885.1110 · fax 270.886.8462 1800264-9571 central hydraulics inc stocking
