FAQ

Q: Is this a direct fit for my Isuzu 4JA1 engine, or is machining required?
A: This is a genuine Taiho bushing, designed as a direct OEM replacement. However, professional installation by a qualified mechanic is always recommended. The new bushings are typically pressed into the connecting rods and may require final honing to achieve the exact specified clearance for your crankshaft journals.

Q: Does the set include all the bushings needed for one engine?
A: Yes, this set contains four (4) individual brass bushings, which is the complete quantity required for one 4-cylinder Isuzu 4JA1 engine (one bushing per connecting rod).

Q: What are the signs that my connecting rod bushings need replacement?
A: Common symptoms include audible knocking or tapping sounds from the engine lower end, especially under load; low oil pressure; and visible excessive wear or scoring on the crankshaft journals. Metallic debris in the oil filter is also a critical indicator.
