Hi,

I broke the washer that goes between the circlip from hell and the third 
gear bushing on my TR6 gearbox. Don't ask. Suffice to say "stupid". At any 
rate, the folks at Moss had new ones in stock. So I purchased one and it 
looks like the proper part.

Unfortunately, the part is about .010 too thick and I cannot install the 
circlip from hell to hold things together. I'm talking .000 end-float 
between the 2nd/3rd bushings and the circlip will not seat.

Undaunted, I decided to see if I can "fix" the fitment, as the washer 
(this is the one with the flutes cut in so it does not spin against the 
circlip) had a rough grey-ish finish and all the trannies I've ever taken 
apart have a smooth shiny finish to this part. Using some cutting oil and 
some emery paper, I've managed to polish off about .005" from the part to 
this point. I've also managed to consume about an hour polishing and I 
still have a guestimate that another .005" needs to come off the part 
before it'll install and give me .003" min. end-float.

My question to the group: does this seem like a proper approach to the 
problem? I suppose I could pull parts from another tranny, but I've got 
only one spare and I'll need to address the broken washer at some point 
anyway, so I'd like to make do with what I have in hand.

Note: this is a $50 part (new), not a $10 spacer washer.

Just curious.
