n Disassembly

n General Disassembly Instructions

The following instructions provide necessary information to disassemble, inspect,repair, and assemble product. Parts drawings are provided in Product PartsInformation Manual.If a product is being completely disassembled for any reason, follow the order oftopics as they are presented. It is recommended that all maintenance work on productbe performed in a clean dust-free work area.In the process of disassembling product, observe the following:1. Never disassemble product any further than is necessary to accomplish needed

repair. A good part can be damaged during the course of disassembly.2. Never use excessive force when removing parts. Tapping gently around perimeter

of a cover or housing with a soft hammer, for example, is sufficient to break theseal.

3. Do not heat a part with a flame to free it for removal, unless part being heatedis already worn or damaged beyond repair and no additional damage will occurto other parts.

In general, products are designed to permit easy disassembly and assembly. The useof heat or excessive force should not be required.

4. Keep work area as clean as practical, to prevent dirt and other foreign matterfrom getting into bearings or other moving parts.

5. All seals, gaskets and ‘O’ rings should be discarded once they have been removed.New seals and ‘O’ rings should be used when assembling product.

6. When grasping a part in a vise, always use leather-covered or copper-covered visejaws to protect the surface of part and help prevent distortion. This is particularlytrue of threaded members, machined surfaces and housings.

7. Do not remove any part which is a press fit in or on a subassembly unless removalof that part is necessary for repairs or replacement.

8. When removing ball bearings from shafts, it is best to use a bearing puller. Whenremoving bearings from housings, drive out bearing with a sleeve slightly smallerthan outside diameter of bearing. The end of sleeve or pipe which contactsbearing must be square. Protect bearings from dirt by keeping them wrapped inclean cloths.

n Cleaning, Inspection and Repair

n Cleaning

Clean all product component parts in solvent (except brake bands and disc brakefriction plates). The use of a stiff bristle brush will facilitate removal of accumulateddirt and sediments in the reduction assembly, on housings, frame and drum. Dry eachpart using low pressure, filtered compressed air. Clean brake band using a wire brushor emery cloth. Do not wash brake band in solvent. If brake band lining is oil soaked,it must be replaced.

n Inspection

All disassembled parts should be inspected to determine their fitness for continueduse. Pay particular attention to the following:1. Inspect all gears for worn, cracked, or broken teeth.2. Inspect all bushings for wear, scoring, or galling.3. Inspect shafts for ridges caused by wear. If ridges caused by wear are apparent

on shafts, replace shaft. Inspect all surfaces on which oil seal lips seat.4. Inspect all bearings for play, distorted races, pitting and roller or ball wear or

damage. Inspect bearings for freedom of rotation.5. Inspect all threaded items and replace those having damaged threads.6. Inspect band brake lining for oil, grease and glazing. If band brake lining is oil-

soaked replace brake bands as a set. Remove glazed areas of band brake liningby sanding lightly with a fine grit emery cloth.

7. Measure thickness of band brake lining. If brake band linings are less than 0.062inch (2 mm) thick anywhere along edges replace brake bands as a set.

8. Inspect cylinder bores. Minor scratches in bore lining may be repaired by lightlyhoning to remove. Refer to tolerances listed below for acceptable clearances.Replace liner if deep scratches or gouges are apparent. Measure inside diameterof liner. If measurement is greater than 4.764 inches (121 mm) replace liner.‘Ring Gap’ may also be used to determine wear; place compression ring into liner,using a piston, push ring until approximately half way in liner and measure ‘Gap’— 0.003 inch (0.076 mm) is normal; replace rings, or liner, if ‘Gap’ exceeds 0.020inch (0.51 mm).

9. Inspect the drive plates for warpage or other damage, and replace damaged partsas necessary. Replace the input pinion shaft oil seal.

10. Measure the thickness of the brake friction disc. The brake friction disc must showan even wear pattern. If the brake friction disc is 0.076 inch (1.93 mm) or less,replace the disc.

n Repair

Actual repairs are limited to removal of small burrs and other minor surfaceimperfections from gears and shafts. Use a fine stone or emery cloth for this work.Do not use steel wool.1. Worn or damaged parts must be replaced. Refer to the applicable parts list in the

Product Parts Information Manual for specific replacement parts information.2. Inspect all remaining parts for evidence of damage. Replace or repair any part

which is in questionable condition. Cost of the part is often minor in comparisonwith cost of redoing job.

3. Smooth out all nicks, burrs, or galled spots on shafts, bores, pins, or bushings.4. Examine all gear teeth carefully, and remove nicks or burrs.5. Polish edges of all shaft shoulders to remove small nicks which may have been

caused during handling.6. Remove all nicks and burrs caused by lockwashers.7. Replace all gaskets, oil seals, and ‘O’ rings removed during product disassembly.
