Help, I need 2mm

noquarternoquarterMember
Had (have) an oil leak at the rear of the engine in the Pantera. Oil pan is off, so is main cap. Took me 3 hours to push out the old rope with several fabricated tools. But now I can't the new rubber lip seal pushed into the block, max 45 degrees of the required 180 degrees.
I've lowered all the main caps and tried to lower crank, but it doesn't seem to move.
Now, the gearbox is still on, so I know I can't lower the crank a lot, but I only need a little. How can I lower the crank a little, can it be done without removing gearbox? Can I take out the 6 bolts and then let the gearbox and crank fall down 2mm? Or is the clutch axle a little flexible, only held in place and aligned by the crank? Confused

As you can see any advise to find a 2mm lowering of the crank is welcome.

Could you briefly explain?

I have not personally used one, but...

See the round coil?

That is what we here call a 'chinese finger'. You may have seen one made of woven bamboo as a kid at a carnival or fair. You would stick your two fingers in the ends and then try to pull them apart. It grabs and gets tighter as you pull.

The wire chinese finger is slipped through the seal groove and the seal inserted into the finger. The handle for the finger is the item with the tapered end. It has a notch that indexes with the crimped-on end of the wire finger. Pull the new seal in place.

May not be a total no-brainer in practice, but sure beats trying to push it in.

I'm sure they come with instructions, and no doubt someone on the forum here has used one?

Here's a killer.....

In the past, rope seals were held in place with a pin...in the block....

If you pulled your old rope seal out, take a look at it and see if there was a line in the center of it about half way around...and not on the other side!?????

No line, no pin. You should be able to push the rubber seal around......especially if you have already dropped the crank down a tad...

Loosening your mains should let your crank drop enough to do this job. You are right, you do not need much!

Your timing chain will keep the front of the crank from dropping.
