YJH3.15H-3A-TL Torque Converter for Tailift 4105/4108 Forklift
The YJH3.15H torque converter is a hydraulic torque converter assembly designed for Tailift forklifts powered by 4105 and 4108-series diesel engines — a driveline platform commonly found on Tailift FD30-FD50 3T-5T models. The YJH3.15H-3A-TL specification covers the pump impeller diameter, turbine blade angle, stator one-way clutch stall speed, and pump drive tang configuration — parameters tuned specifically to the torque curve of the 4105/4108 engine family and the hydraulic transmission shift logic used in Tailift vehicles. Installing a non-spec converter with different stall characteristics causes either sluggish acceleration (stall speed too low) or excessive transmission heat and fuel consumption (stall speed too high).
Manufactured with precision-cast impeller and turbine blade profiles matched to the YJH3.15H specification, this torque converter assembly includes a hardened stator one-way clutch that locks under torque multiplication and freewheels at coupling speed. The pump drive tangs are machined to match the Tailift flex plate, and the turbine output spline is cut to the Tailift transmission input shaft specification. The assembly is factory-balanced to minimize driveline vibration that accelerates crankshaft thrust bearing wear and transmission input seal leakage.
Direct replacement for Tailift FD30, FD35, FD40, FD45, FD50 forklifts with 4105 or 4108 diesel engines and YJH3.15H-3A-TL torque converter specification. Always replace the transmission oil and filter simultaneously — a new converter installed with contaminated oil will fail prematurely.

Each YJH3.15H torque converter ships sealed with assembly lubricant. Prime the converter with clean transmission oil through the pump drive opening before bolting to the flex plate. After installation, fill the transmission, start the engine, cycle through forward and reverse at idle, then recheck the oil level — the converter and cooler circuit will absorb additional oil on the first fill. For Tailift driveline specifications, consult Baldwin Filters. Kingstream stocks the YJH3.15H for freight shipping — worldwide delivery with online tracking.
