barn fresh 175DT
« on: June 17, 2011, 06:29:03 PM »
Hi all. New to the forum here and also to Bridgestones, but not to bikes. A friend of mine recently got his father-in-laws 66 175DT and wants me to rework it , possible not a full on resto but presentable none the less. Pulled the jugs and seems that BOTH outter circlips for the piston pins were missing , and very deep grooves in cylinder where the pins walked out. Is this a common thing or did someone maybe forget to put them back in?  Reason I think that is because there it still crosshatch in the cylinders , NO rust at all in them and ODO reads 16,000 plus miles. 
Here are a couple pics of what I am starting with , IF they post

That's a nice one.... it looks to be pretty complete. I've never heard of missing circlips so there must be a story to that. You will probably never know how that happened.
I have a tilt wheel for more headroom!

Everything is there and straight too! Makes up for that though with all the surface rust. Anyone have any idea what the 2 longer brackets attached to the rear shocks might be?

Brackets possibly for saddle bags? Saddlle bags were a fairly common owner or dealer instaaled  option in those days

I have the engine cases all cleaned/degreased. What is the best way to get the factory finish back on them?  There is obvious discoloration in spots that won;t clean up. Can a person use walnut shells in a blast cabinet or a soda blaster to bring back the origional sheen?   Thanks

I have just done my cases on my Bridgestone GTR i blast them in the cabinet then i wash them in soap and water!
Then i put them in the ultrasonic tank bring them out let them dry then soda blast with baking soda.
Wash them again with soap and water leave in the sun to dry,then i coat with ACF50 to seal the casings.
And that's it! i will get some pictures.
PS i use the carpet baking soda because it gives a nice shine on the engine casings and cheap to buy.
Thanks.
Steve.

Its a lot of work to do all that you can send your casings to be Vapour blasted that does a very nice finish as well.
Thanks.

Finally back to working on this gem again , been a real cooker here in Ohio!!!   Got the engine cases cleaned up , degreased the  heck outta them and soda blasted afterwards. Looks pretty good.  Ordering the rest of the engine parts from Richard in a day or 3 so maybe get this engine entirely back together before snow flies. In the mean time , frame to be cleaned up and repainted. Have the smaller body work all cleaned and primed , ready for paint. This won;t be a factory resto , more of a resto-mod I guess you would call it? Pretty close but a few personal touches.

Steve

here are a couple photos of the cases. Still need to clean with some carb cleaner to rid the excess gasket sealer. Considering how they looked before cleaning , they came out pretty good. Have some dark oxidation?  that hard to get rid of though. All I did was to blast them with Arm and Hammer baking soda thru my siphon gun after degreasing.

Good job, and all the work done at home in your own workshop!
And at very little cost plus your time.
Thanks.
Steve.

I have a DeVilbis 25 gal , 5 hp 125psi. this is like 10cfm @ 90psi.  The suction hose is only about 1/8 - 3/16" id that I put into the soda and have to wiggle it around sometime to keep the soda flowing. Also have bout a 3/16" opening on the blaster tip.

If I run my blaster with the larger tip it will run out of puff , but not much of a problem at all with the smaller tube and tip for the soda blasting. The biggest problem I have is with it so humid the last few weeks is moisture in the line , I need a bigger moisture trap.
