FAQs
Q1: What exactly is included in the kit?
Pistons, cylinder liner, piston rings, bearings, and a full engine overhaul gasket set.
Q2: Which machines does it fit?
Bobcat loaders (1213, 843, 853, 960, 2060, 2070), Sumitomo excavators (SH60, SK60), ISUZU trucks (NHR, NKR, TF, TFR, TFS, Mustang) and JMC vehicles (493, JX493Q1, light trucks) powered by the 4JB1 2.8L diesel. Always confirm the engine model on the nameplate and the OEM number before ordering.
Q3: Which piston variant should I choose — square base or round base, 31mm or 34mm pin?
The listing offers four combinations (Square/34mm, Square/31mm, Round/34mm, Round/31mm). Choose according to the original piston you are replacing; if the piston's base shape and pin diameter are not clear, send a photo or measurements to the supplier for confirmation.
Q4: Is this for the turbo (4JB1T) or non-turbo (4JB1) engine?
The kit is primarily for the 4JB1 non-turbo 2.8L engine; some listing lines also reference the 4JB1T. Verify which engine model your machine uses and confirm the correct kit with the supplier.
Q5: How do I verify the OEM number?
Compare the number on your original part with the listed reference 8971766850. If there is no direct match, confirm fitment with the seller before purchasing.
Q6: Is this OEM or aftermarket?
It is an aftermarket overhaul kit without stated brand or OEM certification. We recommend asking the supplier for material documentation (piston, liner, bearings) and dimensional inspection reports before bulk purchasing.
Q7: Is there a warranty?
No warranty terms are stated in the title. Please confirm the return/exchange policy and quality guarantee with the supplier before ordering.
