Before you order
Frequently asked questions
What dimensions are confirmed by the supplier sheet?
A 30 mm reference crank pin diameter is legible. Pin length and detailed oil-hole geometry are not supplied legibly and must be confirmed against a drawing or sample.
Does this fit every CG engine?
No. CG250, ZS250 and 167FMM are supplier application references. Balance-shaft versions, smaller CG engines and different vehicle installations require independent dimensional and structural review.
What does the 65 mm stroke example mean?
It illustrates final stroke = original stroke + 2 × eccentric offset. The 65 mm base is an example, not confirmation of your engine stroke. Final offset availability and assembly clearances require approval.
Are packaging and workshop photos product-specific proof?
No. They are supplier-provided general packaging and workshop references. They do not prove production, inspection, bearing inclusion or packaging configuration for your order.
What is the minimum order quantity?
MOQ is 300 pcs. Confirm the order unit and final supply configuration, including any pin, bearing or accessories, in the quotation.
Can I request a custom configuration?
Yes. Send your engine model and year, drawing or sample, required dimensions, quantity and destination country. Custom specifications and supply configuration are subject to technical review. Material, hardness, tolerances, certification, branding and packaging require explicit agreement; they are not assumed.
