Pressure plate mounting surface to flywheel surface distance
Perhaps a tiddly point, but what is the pressure plate mounting surface to flywheel friction surface distance supposed to be? I've seen 1.120", 1.123", and 1-1/8" (1.125"). I suppose there is some leeway that can be taken up in pressure plate finger adjustment, but I'm having my flywheel surfaced and I need to tell the machine shop something. Before resurfacing it's currently a fat 1.125" so I suspect the pressure plate mounting surface will need to come down some.
I'm thinking of telling the machine shop to machine it to 1.121"/1.125" (that is, 1.123" +/- 0.002"). Does this seem reasonable? Thanks in advance, as always.

Re: Pressure plate mounting surface to flywheel surface distance
1.123 is exactly what 3 of mine measured.

Re: Pressure plate mounting surface to flywheel surface distance
I have ground a couple hundred in a winona-van norman grinder. Always ground to 1.125. + or - .002 is just fine.

If only the replacement clutch linings were a uniform thickness!! What do you suppose a thicker/thinner lining does for that number? . |

Given that I'm already at 1.125"-1.126", I'm going to have the shop set the distance at 1.122"/1.125".

Gee I wish I had seen
that print 40 years ago! The final step of checking and adjusting the fingers is what counts. |
