0731201563 Auxiliary Box Pneumatic Cylinder Assembly-Cylinder Pin, made of high-quality alloy steel through quenching and precision grinding, produced to original factory dimensions with wear-resistant and rust-proof surface and precise assembly clearance. It effectively avoids piston offset and high-low gear shifting lag caused by pin wear and looseness, directly installed without modification and comparable to OEM durability. Fits ZF12TX2620, ZF12TX2621, ZF16S2230, ZF16S2530, ZF16S2531 transmissions.
0731201563 Cylinder Pin
0731201563 Auxiliary Box Pneumatic Cylinder Assembly-Cylinder Pin, produced from premium alloy with overall quenching heat treatment and inner-outer precision grinding, strictly machined per OEM drawings with tight tolerance. Anti-rust and surface hardening treatment boosts wear and impact resistance against long-term reciprocating abrasion. It accurately locates pistons to resolve common faults such as gear jumping, sluggish high-low shift and cylinder air leakage caused by pin looseness, enabling direct OEM installation without trimming. Fits ZF12TX2620, ZF12TX2621, ZF16S2230, ZF16S2530, ZF16S2531 transmissions.
