Frequently Asked Questions
Why does my R129 convertible top stop mid-cycle?
The R129 hydraulic soft-top system is a well-documented trouble area. Common causes include a failing hydraulic pump, degraded cylinder seals, or faulty limit switches. This manual provides complete hydraulic circuit diagrams, fluid specification data, cylinder seal replacement procedures, and switch adjustment specs to diagnose and resolve top-operation faults.
Which SL-Class model variants are included in this manual?
All R129-chassis variants are covered, including the SL300, SL320, SL500, SL600, SL55 AMG, and SL73 AMG. Both standard soft-top convertible and optional removable hardtop configurations are documented throughout. The R129 represented Mercedes’ fourth-generation SL roadster and was sold in the US from the 1990 model year onward.
Are the 722.6 automatic transmission rebuild procedures included?
Yes. The manual covers the 722.3, 722.5, and 722.6 NAG1 automatic transmissions used across all R129 variants. Documented procedures include conductor plate replacement (a known R129 failure point), complete fluid and filter service intervals, torque converter removal, valve body disassembly, and full rebuild specifications with torque values.
