When using a mechanically driven tachometer, parts are available both from CaseIH and Cummins for a B series engine to allow such a tachometer to be driven. This tachometer drive is installed into the front timing gear cover and is a 90 degree drive (total speed reduction relative to crankshaft speed is 2:1). In some situations, a longer tach drive cable will be required to reach the drive. The cable from a White 2-135/155 is a good option when additional cable length is needed to reach the tachometer drive. Note that certain Perkins applications used a 1:1 drive ratio and will require a different tachometer to work with the Cummins 2:1 tach drive.
Air Conditioning Compressor Mounting
Components to mount a Sanden style compressor are available to place the compressor on top of the cylinder head on the drivers side. This configuration drives the compressor with a V belt which is driven by a pulley that gets sandwiched between the serpentine pulley and the fan hub spacer installed on the fan hub.
Cold Starting Aids
In northern climates, some form of starting aid is usually required to start a diesel engine during cold ambient conditions. In pickups, the B series engines were equipped with an electrical grid heater to warm the air entering into the intake manifold. This is a viable option, but may limit the number of off the shelf air intake piping options. Another option is to install a factory ether starting kit. Although ether sometimes has a bad reputation, when used properly with a factory engineered ether system, the risk of engine damage is low. In fact, with some modern large displacement engines, the engine's electronics will monitor crankshaft speed after a cold start and administer ether even while the engine is running to improve cold idle stability and reduce white smoke.
