Clutch failure
Posted: Sun Jan 16, 2011 12:12 pm
I had to drive to Pretoria yesterday for some business. Petrus ran very well as always. I enjoyed the 1500 box's short gearing on pulloffs down Potgieter Street (some people get very cheesed off when an old fart in an old Beetle show them a clean pair of heels from the robots)
On completion of my business, when I started Petrus again an ominous clattering sound was emitted when the engine fired. "Fook, Bearings" I thought, but realised that the noise only appeared when I depressed the clutch.
Then it dawned on me, something in the clutch had died.
I did not have time to wait for Outsurance's recovery (very handy if you drive an old car), so I decided to drive it cluchless and change on revs.
Snicked it into first and started the engine - He jerked into life and trundled out the parking area. It was a bit of a mission to join the traffic as I had to kill the engine, engage first, wait for a suitable gap and hit the starter button (ignition switch is only for decorative purposes on this one). Join the traffic on starter power and accelerate away as the engine fires.
Now I had to judge the traffic flow as I had to kill the engine to engage first if I got stopped at atraffic light. Had to do that on two occasions.
Coming up Schubart Street, I had to pull of on the starter at the first robot, accelerate to a suitable speed in first, slightly come of the power and simultanously slip it into neutral, then blip the throttle and at the right engine speed (approx 1500 rpm) gently slip it into second. If you get the feel for it, the gear engage without any grinding.(Thank you for the good synchros, Dr Porche)
By sticking to about 50 kph, I managed to time the synchronising of the traffic lights perfectly and only had to stop at the beginning of Potgieter Street again.
Repeated the starter pulloff procedure and held it in third up to the beginning of the freeway, where I snicked into fourth and I was on my way back to Centurion.
Coming off the highway required a reverse of the procedure to go down the gears.
Slow down sufficiently, come off the power, slip it into neutral, blip the throttle, snick it into third; repeat to get second and eventually first. Timed the robot right and managed to get back to the shop without further hassles.
So Petrus is on sick leave until I can find the time to pull the engine. (my car goes on the back burner as I have a customer's racing 1975 Cortina Big Six in the shop to sort out this week)
As for the clutchless gearchange, all I can say is "a misspent youth is better by far than a wise and productive old age" (Meatloaf)
