K70 story
The car started out as a successor to the NSU Ro80, but was bought by VW before it was launched.
My car is a 1973 K70L, 75hp, repainted in the 90's, interior is very good, not much rust. It needs some work to get in very good condition, my plan is as follows:
* Engine work, gaskets, rubber hoses, valve seats and clutch
* Undercarriage, new shocks and change rubber parts
* Interior bits, new carpets
* New windscreen and rear window
* Some rust welding and repaint
Links and part sources:
* Some local sources here in Norway, contact me for details
* Knut at Veteran og VW Service
* eBay, DE and UK
* The German K70 owners club has a large NOS part pool, a membership and part pool fee is required
* Mario at Autoteile Thimm manages the NOS part pool
* K70 Freunde have a part pool list.
Front shock replacement
I stripped all original paint from the suspension parts and drive shaft, coated with two component primer and matte black colour. New outer drive shaft joint and all new rubber parts too.
Still looking for a new insert/cartridge to replace the front shocks though. Original parts are impossible to obtain. Mine has the following markings: VW#481 412 031E and BOGE 0211 32 029.
Starter refurbish
I refurbished my starter. New brushes, black paint and alu cleaned nicely.
Headlight reflector change
I've got the late type of square headlights, but both reflectors were badly corroded. There's a earlier bigger type of headlights too, (up to 1972 models) which have a larger front glass area and a bucket-type metal part on the back. In addition to this, there seem to be two types of the newer lights, and to make it really simple I have one of each. One type has got simple pin-type fasteners between the metal frame and reflector, the other have more rigid plastic fasteners. See the pictures for details. I was lucky enough to get new reflectors for both, and resprayed the metal frames to a nice finish.
Headlight adjustment
The K70 user manual even comes with a procedure for headlight adjustment. Very handy indeed! Here's a copy of the pattern and adjustment directions:
Place the car 5 metres from a vertical wall. Measure the distance from the floor to the centre of the dipped beam light output (d) and mark this on the wall. Draw a line 5 cm below this line (H-H). Measure the distance between the lights (a). The light cone should hit the wall as indicated in yellow.
New clutch
TeileThimm sent me a new Sachs clutch (Sachs# 1861 769 235 )and an new clutch bearing (VW# 006 141 165 B). Job done in 4 hours, including cleaning of the flywheel/cluch housing and plastic covers. Do as follows:
1: All sparks plug out to simplify engine turning
2: Clutch plastic covers off, (there's two of them)
3: Loosen the adjustment knob on the clutch pedal
4: Disconnect the clutch wire from the release arm
5: Loosen the release arm ball pivot bolt, remember to loosen the lock nut first (green arrows)
6: Remove two bolts on the bearing sleeve, pull backwards (green arrows)
7: Loosen the drive shaft lock ring and push it back into the gearbox (red arrow)
8: Remove all bolts on the flywheel to remove the clutch press plate
9: Insert new clutch, and reinsert the clutch plate, insert all bolts but do not tighten
10: Push in the driveshaft to center the clutch, then tighten all bolts in a star pattern (may require some fiddling to get it centered)
11: Put it all together, adjust the release arm ball pivot so the arm is a bit loose and the bearing does not engage
12: Adjust the knob on the pedal
Powder coated steel rims
Original colour, but a hint of metallic in it. Powder coated at Opems Pulverlakkering.
Refurbished brake parts
I got hold of a NOS 19mm brake main cylinder from Veteran og VW service. The main brake vacuum servo has been repainted in matte black colour.
