TM 5-3895-374-24PORDERING PARTS:When ordering parts for reducer, specify reducer size number,reducer serial number, part name, part number and quantity.It is strongly recommended that when a pinion or gear isreplaced, the mating gear or pinion be replaced also.If the large gear on the output hub must be replaced, it isrecommended that an output hub assembly with a gearassembled on the hub be ordered to secure undamagedsurfaces on the output hub where the oil seals rub. However, if itis desired to use the old output hub, press the gear and bearingoff and examine the rubbing surface under the oil seal carefullyfor possible scratching or other damage resulting from thepressing operation. To prevent oil leak- age at the shaft oil sealsthe smooth surface of the output hub must not be damaged.If any parts must be pressed from a shaft or from the outputhub, this should be done before ordering parts to make sure thatnone of the bearings or other parts are damaged in removal. Donot press against outer race of any bearing.Because old shaft oil seals may be damaged in disassembly it isadvisable to order replacements for these parts.If replacing a bearing or a shaft, it is advisable to order a set ofshims for adjustment of bearings on the shaft assembly. Ifreplacing a housing, a set of shims should be ordered for eachshaft assembly because the adjustment of the bearings on eachshaft assembly is affected.page C6 - 5
