You are buying another machine\u2019s old problem. A remanufactured unit is disassembled down to the last bolt, inspected part by part, rebuilt with new seals and wear components, and tested before it ever reaches your shop.\u00a0<\/span>That is the difference between a temporary patch and a long\u2011term solution.<\/span><\/strong>\u00a0[8\u2020L4-L6]<\/span><\/p>\n2. Key Features & Benefits<\/span><\/h3>\n\n- \n
OEM cross reference 114-1357<\/span><\/strong>\u00a0\u2013 Direct replacement final drive travel motor for Caterpillar 325B, 325B L, 320B, 322B, and 322L excavators. Additional compatible models include 325B LN, 320B S, 322B LN and 322B L excavators.<\/span><\/p>\n<\/li>\n- \n
Complete 6\u2011step remanufacturing process<\/span><\/strong>\u00a0\u2013 Every unit is stripped to bare housings, cleaned, inspected for cracks (using dye penetrant testing on all major castings), worn components replaced (piston block, cylinder barrel, valve plate, bearing set, all seals and o\u2011rings), reassembled with new OEM\u2011grade internal parts, and tested on a dyno for correct pressure, flow and case drain before it is approved.<\/span><\/p>\n<\/li>\n- \n
Two\u2011speed travel capability<\/span><\/strong>\u00a0\u2013 Integrated two\u2011speed shifting allows the operator to select high speed for site travel or low speed\/high torque for demanding digging, pushing and climbing.<\/span><\/p>\n<\/li>\n- \n
Heavy\u2011duty cast iron housing<\/span><\/strong>\u00a0\u2013 Manufactured with a robust cast iron housing and precision\u2011ground planetary gears. Surface\u2011hardened tooth profiles ensure long wear life under high torque.<\/span><\/p>\n<\/li>\n- \n
Integral multi\u2011disc parking brake<\/span><\/strong>\u00a0\u2013 Built\u2011in wet disc parking brake engages automatically when travel controls return to neutral, holding the machine securely on slopes. Brake releases instantly when travel command is given.<\/span><\/p>\n<\/li>\n- \n
Fully tested before shipping<\/span><\/strong>\u00a0\u2013 Each remanufactured final drive is run on a hydraulic test stand to verify:<\/span><\/p>\n\n- \n
Correct operating pressure (typically 350\u2013400 bar \/ 5,000\u20135,800 psi)<\/span><\/p>\n<\/li>\n- \n
Smooth speed progression through both ranges<\/span><\/p>\n<\/li>\n- \n
No internal leakage past the case drain (critical for avoiding blown shaft seals)<\/span><\/p>\n<\/li>\n- \n
Quiet gear train operation (no bearing rumble)<\/span><\/p>\n<\/li>\n<\/ul>\n<\/li>\n- \n
Visual verification prior to dispatch<\/span><\/strong>\u00a0\u2013 Before your final drive is packed, we send you detailed photographs of the unit from multiple angles, including close\u2011ups of mounting surfaces and port locations. You approve the condition before we ship. This is not negotiable \u2013 you see exactly what you are getting.<\/span><\/p>\n<\/li>\n- \n
Professional export packaging<\/span><\/strong>\u00a0\u2013 Each final drive is securely packed in a heavy\u2011duty, fumigation\u2011free wooden case with internal bracing and padding to prevent damage during transit.<\/span><\/p>\n<\/li>\n- \n
Fast delivery<\/span><\/strong>\u00a0\u2013 5\u20138 working days lead time from our Guangzhou warehouse. Monthly supply capacity of 300 units, available for single or bulk orders.<\/span><\/p>\n<\/li>\n<\/ul>\n3. Applications<\/span><\/h3>\nThe CAT 325B final drive is a high\u2011demand component across multiple heavy industries where reliability is non\u2011negotiable:<\/span><\/p>\n\n- \n
Mining & quarry operations<\/span><\/strong>\u00a0\u2013 Final drives on 25\u2011ton class excavators endure extreme shock loads, abrasive dust and long continuous shifts. A remanufactured unit with new bearings and seals provides the same durability as new, for a fraction of the cost.<\/span><\/p>\n<\/li>\n- \n
Heavy construction & earthmoving<\/span><\/strong>\u00a0\u2013 Highway projects, dam construction, large\u2011scale site preparation and pipeline trenching all demand consistent travel performance. A failing final drive will leave a 325B immobile in the middle of a job site, and towing a 25\u2011ton excavator is neither quick nor cheap.<\/span><\/p>\n<\/li>\n- \n
Demolition & scrap processing<\/span><\/strong>\u00a0\u2013 325B excavators working in demolition or metal recycling face intense vibration, sharp debris and repeated hard impacts against the undercarriage. The planetary gearing inside a remanufactured final drive is rebuilt to absorb these extreme shocks without internal damage.<\/span><\/p>\n<\/li>\n- \n
Forestry & land clearing<\/span><\/strong>\u00a0\u2013 Steep slopes, soft ground and hidden obstacles are routine in forestry applications. A reliable final drive with predictable two\u2011speed shifting prevents machine\u2011stranding failures far from repair support.<\/span><\/p>\n<\/li>\n- \n
Equipment rental fleet maintenance<\/span><\/strong>\u00a0\u2013 Renters are hard on undercarriage components. A final drive that fails mid\u2011rental damages customer relationships and costs days of lost revenue. A remanufactured unit provides a fresh start at a cost that makes proactive replacement economically sensible.<\/span><\/p>\n<\/li>\n- \n
Cold climate & winter operations<\/span><\/strong>\u00a0\u2013 In sub\u2011zero environments, worn seals and bearing cages are far more likely to fail. Our remanufacturing process includes new low\u2011temperature rated seals where specified, ensuring reliable cold\u2011weather starting and travel.<\/span><\/p>\n<\/li>\n<\/ul>\n4. Why Choose Hongtengda Parts \u2013 The Remanufacturing Difference<\/span><\/h3>\nThe key question every buyer asks:<\/span><\/strong>\u00a0<\/span>Why should I trust a remanufactured final drive with no conventional warranty?<\/span><\/em><\/p>\nHere is the honest answer: A warranty is a promise to fix something if it breaks. A proper remanufacturing process is a promise that it will\u00a0<\/span>not<\/span><\/strong>\u00a0break in the first place. At Hongtengda Parts, we prioritise the work up front: meticulous disassembly, component\u2011by\u2011component inspection, replacement of all wear parts, and rigorous pre\u2011shipment testing. We do not rely on a warranty to cover our work; we rely on the quality of the work itself.<\/span><\/p>\n\n- \n
Certified remanufacturing standards<\/span><\/strong>\u00a0\u2013 Our processes align with national and international remanufacturing guidelines. Under established industry standards, remanufacturing is defined as using advanced processes to restore a used component so that its performance and quality meet or exceed that of a new product. [8\u2020L4-L6] We operate to this standard, not to a lower \u201crepair and patch\u201d level.<\/span><\/p>\n<\/li>\n- \n
Six\u2011step reman process, fully documented<\/span><\/strong>:<\/span><\/p>\n\n- \n
Initial inspection & intake<\/span><\/strong>\u00a0\u2013 Each core is evaluated for structural integrity. Irreparably damaged castings (cracked housings, stripped mounting threads) are rejected.<\/span><\/p>\n<\/li>\n- \n
Complete disassembly<\/span><\/strong>\u00a0\u2013 The unit is stripped down to individual components: bearing cages, planetary carriers, ring gears, spindle shaft, piston block, cylinder barrel, valve plate, hydraulic motor section and brake pack.<\/span><\/p>\n<\/li>\n- \n
Cleaning & crack detection<\/span><\/strong>\u00a0\u2013 All ferrous components are cleaned in a heated parts washer, then inspected using dye penetrant testing on critical castings. Any part showing cracks, spalling or excessive wear is scrapped and replaced.<\/span><\/p>\n<\/li>\n- \n
Wear component replacement<\/span><\/strong>\u00a0\u2013 The following are always replaced with new, not reused: all seals, all o\u2011rings, all gaskets, all roller bearings, the complete piston\/slipper assembly, the cylinder barrel wear plate, and the valve plate.<\/span><\/p>\n<\/li>\n- \n
Precision reassembly<\/span><\/strong>\u00a0\u2013 Components are reassembled using OEM torque specifications. Clearance tolerances on the piston block and valve plate interface are verified using dial indicators.<\/span><\/p>\n<\/li>\n- \n
Hydraulic dyno testing<\/span><\/strong>\u00a0\u2013 The completed final drive is mounted to a test stand, connected to a hydraulic power unit, and run through both speed ranges under load. Test parameters include operating pressure, shaft speed, case drain flow, brake holding torque and noise\/vibration levels.<\/span><\/p>\n<\/li>\n<\/ol>\n<\/li>\n- \n
