The genuine XCMG 800106834 Clutch Housing is a precision‑cast structural component manufactured for XCMG GR series motor graders. This OEM clutch housing encloses the main clutch or torque converter assembly, providing a rigid mounting interface between the engine and transmission. Made from high‑strength ductile iron (GGG50 / EN-GJS-500-7) with precision‑machined mating surfaces and accurately located dowel pins, the 800106834 clutch housing withstands high torsional loads, vibration, and thermal expansion inherent in heavy grading operations. The housing is designed to maintain perfect alignment between the engine flywheel housing and the transmission case, ensuring smooth power transfer and reducing driveline stress on GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 graders.
The 800106834 clutch housing features a fully machined flywheel mounting face, alignment dowel bores, and threaded bolt holes for the engine and transmission. It incorporates a large access port for clutch adjustment / torque converter service and includes cast‑in reinforcement ribs to prevent flex under extreme torque spikes. The housing is stress‑relieved after casting to prevent warpage, and the sealing surfaces are ground to a flatness of ≤0.05 mm. This component is a direct replacement for cracked, warped, or corroded housings in XCMG GR grader powertrains.
A damaged or misaligned clutch housing can cause clutch drag, input shaft bearing failure, transmission gear noise, and oil leaks at the engine‑transmission interface. Replacing a failed housing with genuine XCMG 800106834 restores original drivetrain geometry, eliminates misalignment, and ensures reliable clutch or torque converter operation. Keep this housing in your parts inventory for major powertrain overhauls or accident damage repairs.

The 800106834 clutch housing is the structural union between the engine and transmission. It encloses the clutch pack or torque converter, maintaining precise alignment of the input shaft with the engine crankshaft.
A cracked or warped housing allows misalignment, causing premature failure of the input shaft bearing, clutch shudder, and transmission gear noise. The housing also acts as an oil containment barrier, preventing engine oil or transmission fluid from leaking at the joint.
The cast‑in ribs and thick walls of the 800106834 housing absorb torsional vibrations from the engine, reducing stress on the transmission case. Proper dowel pin alignment ensures the housing is indexed identically every time, eliminating the need for shimming.
Replacing a damaged housing with genuine XCMG 800106834 restores factory alignment, eliminates oil leaks, and prevents costly secondary damage to the clutch, flywheel, and transmission internals.
XCMG produces the 800106834 clutch housing from high‑grade ductile iron (GGG50). The material offers twice the tensile strength of grey cast iron and excellent impact resistance, essential for heavy grading environments.
The housing is cast in a resin‑sand mold, then undergoes a full stress‑relief annealing cycle (600°C for 4 hours) to eliminate residual casting stresses. This prevents warpage during machining and in service.
CNC machining centers perform all critical operations: facing of the engine and transmission flanges, boring of the input shaft hole, drilling and tapping of all bolt holes, and reaming of dowel pin bores. Flange flatness is held to 0.05 mm.
After machining, the housing is thoroughly cleaned and coated with a zinc‑rich primer and satin black topcoat to resist corrosion. Each housing is 100% inspected for dimensional accuracy using a coordinate measuring machine (CMM). Random samples are proof‑loaded to verify structural integrity.
To replace a clutch housing, safely support the engine and transmission. Remove the transmission, clutch, and flywheel. Clean the engine rear face and install new dowel pins if missing.
Position the new 800106834 housing with a new gasket (or apply a bead of anaerobic sealant). Use guide pins to align dowel holes. Install the 6 engine‑side bolts and torque to 120 Nm in a crossing pattern.
Install the clutch or torque converter, then mount the transmission. Use a dial gauge to check input shaft runout at the pilot bearing – maximum allowable is 0.25 mm. If runout exceeds specification, replace the housing – do not attempt to shim.
Keep spare 800106834 housings in your shop for major overhauls. A housing that has been damaged in an accident or by corrosion must be replaced immediately to ensure driveline alignment and safety.
Aftermarket clutch housings are often made from lower‑grade grey cast iron (GG15) that cracks under repeated shock loads. Many have poor casting quality with porosity, leading to oil seepage through the housing wall.
Counterfeit housings may be cast with incorrect bolt hole positions or missing dowel holes, making installation impossible without re‑machining. Some are not stress‑relieved, causing them to warp after the first heat cycle and causing repeated clutch failure.
Genuine XCMG housings are 100% x‑ray inspected for internal voids and certified for material strength. XCMG provides a 12‑month warranty against casting and machining defects. Using OEM housing protects the engine, clutch, and transmission. The cost of a genuine housing is far less than the damage caused by a misaligned aftermarket part.
Visual signs: oil weeping from the engine‑transmission joint, visible cracks near bolt holes or corners, and deformation of the flange face. Audible signs: clutch chatter, transmission whine that changes with engine RPM, and a knocking noise that disappears when the clutch is disengaged.
Preventive replacement is recommended if the housing is removed for any major engine or transmission overhaul. The housing material can fatigue over time, and a visual inspection may not reveal micro‑cracks. When in doubt, replace it.
Keep a stock of 800106834 housings in your fleet warehouse. A cracked housing can fail suddenly, dropping the transmission and causing a driveline separation – a safety hazard. Proactive replacement during scheduled overhauls eliminates this risk and reduces long‑term repair costs.
