MBP 7mm Collet Installation
This is for the DS1000, but figured i put it up here instead because its a 7mm collet.
Anyway, I purchased these from a member here so they are used, but they are pretty much in great shape.
They werent easy to install simply because its hard to get them seated. I am having problem installing it on the last valve im wokring on, specifically the exhaust valve for the vertical cylinder.
The closing shim was originally 3.13mm, and it is now 2.95mm. A call to EMSDUC revlealed that certain batches of collets can cause variance up to .012" or .30mm. That means i still have .12mm to shave off before i start getting out of the norm.
However, on the other 3 valves, ive only had to remove about 0.10mm, not .20mm or .30mm. The cam will not spin at all since either the collets are not seating (ive done everything i can to get them to seat). or the closing shim is too tight.
There is one odd thing out of all this. If i install one particular shim, it will not cause the cam to bind. If i install the other shim, it will bind.
So the question becomes, is there something wrong with the other shim? or does installing one shim not have any relevance?
