Product Description
6RB1 Complete Engine Assembly for Isuzu 6RB1 Diesel Engine — Hitachi EX400-5 Excavator

A complete six cylinder engine assembly for the Isuzu 6RB1 diesel engine, quoted as 6RB1TQA and 6RB1TQA-01. The published service specification for the Hitachi EX400-5 gives the engine as an A-6RB1TQA of 838 cubic inch or 13.7 L, turbocharged, rated 301 hp or 224.5 kW at 2000 rpm with 1230 Nm at 1400 rpm, in a machine of 41,900 kg. A parts catalogue for the designation lists a six cylinder with a 135 mm liner, so the two sets of figures should be read together before a build is quoted.

Verification Notes Before Ordering a 6RB1 Engine
Two capacities are published. The service specification for the EX400-5 gives 838 cubic inch or 13.7 L, while a full gasket set sold for the 6RA1, 6RB1 and 6RB1T group states 12023 cc. The two figures differ by about 1.7 L, so the capacity of the actual build should be taken from the engine plate.
Two build codes differ by one letter. Market entries use both 6RB1TPF-03 and 6RB1TPP-03 for this engine. One letter separates the two codes, so the code on the plate rather than the entry has to be matched.
One machine, several engine names. The EX400-5 is fitted with an A-6RB1TQA, and the same engine code serves the EX400-3 and the EX450-5. Entries sell it as 6RB1, 6RB1-T, 6RB1T, 6RB1TQA-01 and 6RB1TC, so the plate decides and not the heading.
Titles carry up to ten engines. One title names 6WG1, 6HK1, 6HK1T, 6RB1, 6SD1, 6BG1, 6BG1T, 6BD1, 4BG1T and 4BD1 together, and further entries repeat that pattern with 4JB1, 4HK1, 4BG1 and 4LE1. Numbers such as 8-98005408-0 and 8-97600119-0 sit inside such titles without naming which engine they belong to.
Prices and units are not comparable. Advertised figures for a complete assembly run from about USD 1,400 to 7,500, with a group near 400 to 668 and a few near 10 that cannot describe a complete engine. Units are quoted per piece, per set, per parcel and per box, and two suppliers advertise an identical headline at an identical price.
