Special Tools Identification
« on: July 09, 2019, 03:01:28 PM »
I would appreciate any help y'all could provide in identifying the tools pictured below.

Would like the following information on each of them....
1) Part number.
2) Part name.
3) What size engine it's for.

*** not necessary to answer all 3 questions at once, if you can provide just one answer for a particular tool, that puts me that much closer to the info i need. ***

Thanks.....

This morning I posted this over on the Facebook site and these are the results gathered so far from the helpful members there..... (Note: I've since looked in a couple of the Parts Price List manuals I have and have found additional numbers and the actual tool description per Bridgestone and have made the changes to the list as needed. it does appear that all the tools aren't listed in those manuals as I found nothing for #'s 7 & 8, yet those are pictured in the BS50-90 Optional Parts list??? )

Here's one I forgot about. It's a small little thing.... about 1 & 3/4" long and is pictured with the 175 special tools in the previously mentioned Optional Parts List.. Any ideas what it is?

It's an extension shaft that screws into a dial indicator. There should be another piece that has the spark plug thread with a through hole / grub screw to lock the dial indicator into.

So you think this is part of tool #8 above? There are no lines/hash marks or numbers anywhere on it (should there be?) and it would "swim" in the opening of tool #8. It's length is also smaller than #8. I don't see how the 2 would work together, unless some other piece is missing.

I think the missing part of tool #8 is a dial indicator.

Tool #8 would screw into the spark plug hole in the head. Then a dial indicator would slide onto the large hole in part #8.

The bottom of the dial indicator has a wide tube running out the bottom, and a smaller shaft inside of it. It's that wider tube that inserts into tool #8, and is held in place with a set screw.

The shaft above would be screwed onto that smaller shaft of the dial indicator making it long enough to reach down to the top of the piston.

Thanks Al, so the dial indicator would have to be sourced elsewhere or did BS supply/sale any?
