So, went to try and complete the t-belt work I started months ago (procrastinator, par excellence and personal tragedy got in the way.). Could not get the motor to move clockwise. Thought I had screwed up on a massive scale.

Well, I tried to move the gear shift and it will not go into any gears. And I see that the clutch pedal is on the floor. I think either a gremlin or a visitor thought it would be cool to sit in the GTS.

My thinking is that the clutch is locked against the pressure plate.

So, now what?

lift the rear wheels off the ground, release the E brake

 

We need more info. What did you do with the clutch? Have you tried to pull the clutch up by hand? Is the flywheel lock in? If so then on a 5 speed you had to pull the clutch slave. If someone stepped on the clutch then the piston has extended beyond it's normal travel and you may have lost all the fluid. so now you have air in the system and will need to bleed the clutch. You may also need a new slave cylinder as over extending the piston will often damage the seal.

 

Not a lot to add. When we put the flywheel lock in there was a loud clang when we released the crank bolt. Thought nothing of it at the time. When I went to turn the crank the crank would not turn after I removed the flywheel lock. No one admits to pressing the clutch.

I have pulled the clutch pedal back.

What I need are solutions.

 

I'm confused??? Where did the loud clang come from, was it the clutch pedal going to the floor? Why would it do that when you released the crank bolt? Are you talking about the crank bolt that holds the dampener on? Will the engine turn over now? Have you got the belt back on? I think you need to take one step at a time. 1st finish the belt and get it tensioned. Then deal with the clutch pedal. (Assuming the engine will turn over now.)

 

The clang occurred when my helper was turning the engine to 4|5 mark as I was sliding the flywheel lock. The sound came from the area of the pressure plate. I attributed it to the flywheel lock hitting the gears. The engine will not turn. It appears to be in gear.

I did not see the pedal on the floor until I was not able to turn the engine by hand. I believe the car is in gear preventing the engine from turning clock-wise.

I am going to reinstall the slave and get the car out of gear. The new t-belt is on and the flywheel lock is out.

I will post finding tomorrow.

 

can you raise the rear wheels??
This should let the drive line turn

 

First I am going to reinstall the slave cylinder. Then I will raise the rear end.

 

You should be able to shift it out of gear into neutral with the engine off no matter what the state of the clutch is. Then try turning the crank again (of course with the flywheel lock removed).

I agree. This is all very strange to me the gear shift is in the center yet I can not move the gear shifter at all. Not at all the way it feels when it is in out of gear. Peculiar to say the least.

 

Mystery deepens...

Tried to install the slave. Place the rod in the slave and got leak. Slave is toast. I have one to replace it with.

Raised the rear wheels and released e-brake. Wheels turn freely.

Going to have to pull the plugs and see what happens next.

Why won't the gear shift move?

 

Check the dampener and see if it's on backward. (BTDT)

If you install the dampener backward it can rub on the tensioner pivot arm bolt. If it's too tight the engine might not turn at all by hand.

Also, the washer that installs on the crank bolt can be installed backward, I'm not sure what the effect of that would be, I think it just bottoms out without applying the proper torque to the dampener but I'm not sure.

 

Found the culprit. Had pushed back the harmonic balancer back too far while trying to correct an earlier f-up.

Pulled it forward and all is good in the world, except I will have to replace the slave cylinder.

Ahh wait a minute,
if your sliding the damper around and the outer edge is moving and the inner edge isnt,
then you also going to need to replace the damper.
as it could have moved whilst the engine is running thus changing the timing indication of the outer edge of the damper.
A rough check will be the crank keyway points to 3 O clock while looking at the crank and the 45 BTDC is indicated and the cams are also at 45BTDC.
Note TDC is the crank keyway pointing to 4 O clock
Note the damper is vulcanised to the inner and outer portions with a band of rubber,
if either one of these areas are moving then the damper will soon fail and cause other damage. 928INTL half price used sale in 8 days

 

So what about the gear shifter? Surely the harmonic balancer did not affect that? Or was it in gear and under stress from trying to turn the crank, then when you lifted the rear wheels it freed up?
