IHI F31CAD-S0182B is a new, genuine IHI RHF3 turbocharger for the Isuzu 4LE2 2.2L four-cylinder industrial diesel in its Tier 4 form, 2012 and newer. It carries Isuzu number 8982236170, IHI assembly number VA410182 and IHI spec code CIGO. Match it to your engine by the spec code on the old turbo’s nameplate or by the Isuzu number.

Common reasons to replace an RHF3 are shaft play with the wheels touching the housings, oil leaking past the seals, and a damaged compressor wheel from dirt. Find the cause before fitting the new turbo: check the air filter and intake for leaks, the oil supply and drain lines for restriction, and crankcase pressure.
