Book Excerpt: 1976-1985 Mercedes-Benz Diesel Coupe, Sedan, Station Wagon Repair Manual INTRODUCTION
These models are available in 2-door coupe, 4-door sedan and 4-door station wagon (touring wagon) body styles and feature four wheel independent suspension. The 4- or 5-cylinder diesel engines used on these models drive the rear wheels through a choice of 4- or 5-speed manual or 4-speed automatic transmission. Some models are available with turbocharging. Certain models also feature automatic self-leveling of the rear suspension. Steering is of the recirculating ball-type with power assist as standard. Ser vo assisted disc brakes are used on all four wheels and some models are equipped with an Anti-locking Brake System (ABS). There are some detail differences between UK and US models due to local laws and regulations. Some models were available in certain areas, i.e. the 123 series 200D, 220D and 240TD were distributed only in the UK market.

MAINSHAFT | DISASSEMBLY AND REASSEMBLY
  1. Temporarily install the drive flange to the rear of the mainshaft and place the flange securely in a vise with the mainshaft vertical.
  2. Unscrew the nut from the front of the mainshaft using a slotted box wrench where necessary and remove the 3rd/4th synchro unit and synchro ring.
  3. Remove the serrated thrust washer (if fitted) followed by 3rd gear and the needle bearing.
  4. . Remove the mainshaft from the vise, then from the rear, remove the thrust washer, 1st gear and the needle bearing rollers.
  5. Place the mainshaft upright in the open vise with the 2nd gear at the bottom, then use a soft-faced mallet to drive the mainshaft down until the 1st gear needle bearing race is free.
  6. Remove the mainshaft from the vise and withdraw the inner race followed by the thrust washer (if installed), 1st synchro ring, 1st/2nd synchro unit and 2nd synchro ring.
  7. Remove the thrust washer (if installed), 2nd gear and needle bearing.
  8. Clean all components in solvent, wipe dry and inspect them for wear and damage. Press each synchro ring onto its respective gear cone, then use a feeler blade to determine the clearance between the dog teeth. If the clearance is less than specified, replace the synchro ring. If the synchro unit is to be dismantled to replace worn components, first inspect the unit to see whether it incorporates coil or circular type springs.
