Let's see, where to begin
   
  Trannie on the bench for a clutch job, an LBC mechanic will come over and 
we'll pull the trannie top cover and take a look.   Fluid looked good, no bits 
or pieces showed up. Fine particles on the magnetic drain plugs, just normal 
wear I think.  
  the big metal cap on the shifter is proving very difficult to get off, must 
have welded together.   Cold chisel and penetrating fluid I guess.  The 
anti-rattle pin fell out and shifter had too much movement.
   
  Rear engine plate is greasy and dirty, but I can't say there's an obvious 
leak from the rear seal.  I'm inclined to leave it alone as I understand this 
seal can be a finicky job.
   
  Found B&B clutch cover with grooves worn in the stepped style fingers and B&B 
pressure plate.   RHP bearing. The fork pin looks like it was made from a drill 
bit - wasn't broken and correctly safety wired.  will install Luk, Gunst, other 
new parts and drill and bolt fork to shaft.   A TR6 friends says to re-use my 
fork and shaft as he says there's nothing wrong with them.  Return these parts, 
take the wife to dinner.  Drill from trannie through new shaft bushes, install 
grease fittings and smooth new hole in bush
   
  Flywheel at the machine shop for lightening, balancing and re-surfacing.
   As I inderstand it, the material is taken away on the engine side of the 
flywheel and, you only resurface the clutch side?  
   
  Very noticable wear on one section of the flywheel ring gear teeth when 
viewed from the side. Presume that means a new ring gear?  Machine shop would 
put it on.
   
  Mounted my magentic base and dial test indicator on the rear engine plate.  
DTI is made in China - .001 graduations.   There are big black numbers on the 
outside of the face and small red numbers just inside of them.
   
  I took numerous readings by levering the front pulley back and pushing the 
back of the crank forward.   Readings are consistently  in the .011 - 012 
range. (big black numbers on the outside of the face)
   
  I found an article by Jim Davis on the VTR website that said that .007 - .013 
is acceptable.   The manual says .006 - .008.    Is my end float okay?
   
  The catalogues show standard and oversize thrust washers.   What's the 
procedure for determining what you would use? 
   
  Thank you very much
   
  Sigh, the car is apart during the short driving season in this part of the 
country.  Oh well, lots of rain lately.
