Hamilton Cams Cummins Tappets are solid valve lifters and are available for Cummins 24-valve and 12-valve 6-cylinder engines. They are also offered for Cummins 4BT 4-cylinder (8-valve) engines. Cast tappets for 6-cylinder engines feature a 1.450 in. diameter and do not interfere with the fuel pump eccentric on 12-valve engines. Much wider than the 1.100 in. tappets used in early 12-valve engines, their greater surface area makes them perfect replacements. These 24-valve and 12-valve tappets work well with the wider lobes of Hamilton Cams camshafts and promote much better lobe life with today's low zinc oils. For use over 5,000 rpm, with heavy valve springs, or a billet steel cam, Hamilton Cams offers 1.450 in. steel tappets. They are specially designed and manufactured to handle the higher pressures, rpm, and loads of competition use. Hamilton Cams Cummins 4BT tappets have a 1.300 in. diameter; much wider than many 4BT tappets that are only 1.10 in. These cast 1.300 in. tappets allow the pressures between the camshaft and the tappet to be spread over a significantly larger surface area to reduce lobe and lifter wear.

Clearance
Higher rpm, increased boost/drive pressures, and aggressive camshaft profiles can result in valve float and cause serious damage to diesel valvetrains. Valves can also be blown open by higher boost and exhaust drive pressures creating reversion that allows exhaust gas to enter the cylinders on the intake stroke. This re-introduced exhaust gas shields fuel particles from oxygen, delays the start of combustion, decreases cylinder pressure and temperature, and lengthens the time needed to completely burn the fuel … all reducing power. Hamilton Cams valve springs can improve power by allowing higher boost pressures and rpm without valve float or excess reversion. Their single valve springs work well up to 4,500 rpm with moderate-lift camshafts and OEM-size valves. However, as rpm, valve lift, spring pressures, and valve sizes increase, dual Hamilton Cams valve springs are necessary to properly control the valves. For the highest camshaft lifts, they should be used with Hamilton Cams titanium retainers. Note: As a precautionary measure, titanium retainers should be inspected after every season for excessive wear.
