Need help?Do you have a question about the Spicer Axle 30 and is the answer not in the manual?
Shaft bearings are lubricated with hypoid gear lube but require grease packing to prevent damage.
Advises using SAE 80 Multi-Purpose Gear Lubricant for operation below 0°F.
Procedure for submerged gear carrier: drain lubricant daily, inspect for damage, and replace parts.
Do not apply vehicle weight to wheels without half-shafts in place and fasteners properly torqued.
Loosen cover plate screws, remove cover plate and gasket, then drain lube and secure assembly.
Eye protection should be worn when removing or installing the snap rings.
Insert puller through seal and bearing, expand it, and turn screw to center puller.
Place receiver over puller, install bearing and nut to draw bearing and seal from housing.
Assemble new L.H. shaft bearing and seal, seating them correctly against the shoulder or bearing.
Assemble new R.H. shaft bearing and seal, ensuring correct installation depth and seating.
Mount spreader with adapter blocks and screws to carrier, use dial indicator to check spread.
Pry differential case from carrier, remove spreader, and mark bearing cups for reassembly.
Remove differential bearings with a puller, wire shims and cups together, and identify sides.
Place case in vise, remove ring gear screws, and tap ring gear with rawhide hammer.
Drive out lock pin securing pinion mate shaft, then remove pinion mate shaft with a drift.
Rotate side gears to remove pinion mate gears and spherical washers, then lift out gears.
Turn nose of carrier, hold end yoke, and remove pinion nut and washer.
Remove end yoke with tools. Check yoke for wear in seal contact area and replace if needed.
Remove pinion by tapping with a rawhide hammer, catching it to prevent damage.
Pull out pinion seal, discard it, and replace with new. Remove bearing cone and oil slinger.
Remove the inner bearing cup using appropriate tools, noting the baffle and shims.
Turn nose of carrier down, remove outer pinion bearing cup by driving it out of carrier.
Remove inner pinion bearing using appropriate tools such as press and adapter ring.
Assemble side gears and pinion mate gears with thrust washers, ensuring parts are lubricated.
Install pinion mate shaft, assemble lock pin, and peen metal of case over pin to secure.
Ensure flange face is clean, assemble ring gear using new screws, torque to specifications.
Remove nicks, burrs, and dirt from bearing hubs, install master differential bearing onto case.
Mount dial indicator to measure differential assembly for shim pack calculation and preload.
Diagram of gear tooth parts (Profile, Top Land, Heel, Toe, Root) and their relation to contact patterns.
Illustrates pinion dimensions, preload shims, position shims, and centerline of ring gear.
Chart for setting pinion position based on pinion markings and desired gear contact pattern.
View of cross arbor, arbor discs, height block, scooter gage, and master pinion block tools.
Place master pinion block into pinion bore of carrier, ensuring it is properly seated.
Place arbor discs and arbor into cross bores of the carrier, ensuring alignment.
Place pinion height block on top of master pinion block, against arbor for measurement.
Place scooter gage on small step of pinion height block, applying pressure for reading.
Slide scooter gage over arbor, find highest point to measure pinion height, record reading.
Note pinion etching (+/-) to adjust shims for correct pinion position and gear mesh.
Place baffle and shims in inner bearing bore, drive inner bearing cup into carrier.
Assemble the outer pinion bearing cup into the carrier using the appropriate installer tool.
Assemble slinger and inner bearing cone on pinion, drive bearing on stem until completely seated.
Install pinion into carrier, assemble outer pinion bearing cone, slinger, and end yoke.
Assemble washer and pinion nut, torque to 10 lbs-in to check rotation. Check pinion position.
Note on not assembling preload shims and oil seal yet due to potential adjustment needs.
Place arbor and discs in carrier, height block on pinion, set dial indicator to zero.
Install end yoke, washer, and new pinion nut. Torque nut to 200-220 lbs. ft.
Use torque wrench to check pinion rotation torque (20-40 in-lbs). Adjust shims to set preload.
Illustration showing how shims affect backlash and differential bearing load.
Place differential assembly with pinion into housing. Master bearings should be installed.
Force differential assembly away from pinion to get indicator reading for shim pack on ring gear side.
Remove indicator and differential case from carrier. Remove master bearings from differential case.
Mount spreader, adapter blocks, and screws to carrier. Do not spread over .020 inch.
Assemble differential bearing cups to differential bearing cones, then install into carrier.
Install bearing caps, ensuring correct correspondence, and torque bearing cap screws.
Check ring gear and pinion backlash at three points. Tolerance is .005" to .009".
Install axle shafts through side gear spline, place snap ring in groove and force into place.
Fill manufacturing holes with sealant, install new cover gasket and cover plate, torque screws.
Diagram of gear tooth parts (Profile, Top Land, Heel, Toe, Root) and their relation to contact patterns.
Steps to paint ring gear teeth with compound and rotate gear for pattern analysis.
Describes normal or desirable drive and coast patterns, and required clearance.
Summarizes how backlash and pinion position shims affect drive and coast patterns.
