B & H Timing Belt Idler


The B & H Timing Belt Idler is essentially a water pump housing delete. The light weight plate is beautifully machined from US milled 6061 aluminum and incorporates the OEM o-ring groove for a positive seal. The toothed idler pulley rides on precision ball bearings and spins much easier than the OEM counter part!

Several benefits can be traced back to the uncoupling of the water pump from the crankshaft, such as a reduction in parasitic drag, which can free up horsepower and torque. Reduction or elimination of pump cavitation and associated troubles relating to aeration. Better control of the cooling systems temperatures through the use of electronics. Manually override pump and fan(s) to cool the motor while the engine is off.
