All 100 pages of this International BC-144, BD-144, BD-154 Service Manual (OEM #SM12A) zero in on the internals of three closely related gasoline and LPG engines. Open it and you get a full standard torque data section, detailed clearance tables for every valve, bearing, and sleeve, plus page after page of exploded-view diagrams covering the timing gear train, lubrication system, governor, and carburetor. The LPG attachment gets its own dedicated chapter, from vapouriser regulator to priming solenoid, with adjustment procedures you won't find in a generic reference. Hold inlet valve stem diameter to 0.341/0.342 in with a clearance-in-guide of 0.002/0.004 in; on BD-144 and BD-154 engines, torque the nozzle body stud to 20/30 lb ft. Your engine is on the bench and the spec matters. One download, bookmarked by section; search any number, find your answer, get back to work.
