175 DT - 1966
« on: July 15, 2014, 09:14:24 PM »
As if I don't have enough projects already. I'm wrapping up restoration of a 50 sport and cleaning up a 100 Sport but recently found a 175 for sale close to home. I couldn't resist the price so of course I bought it sight unseen.

No gas tank but everything else was there. Heads were in a box but in great shape. Cylinders, not so much. Both stuck and the previous owner tried to get them unstuck by popping the heads off and beating on top of the pistons with a hammer. Both pistons are destroyed. Right jug appears to be undamaged but will need replated. Left cylinder is pretty beat, literally, but I will see if it can be restored.

It looks like a little moisture got into the crank case. Everything else looks great inside but I have this bit of corrosion to deal with. Split cases yesterday and have everything soaking in Kerosene to get the heavy grease and grime loose. I'm amazed at how bad one section of the crank looks while the rest of the internals look brand new.

Going to send the cylinders out for replating and repair. Going to strip the rest of the bike and get the frame blasted and will ponder powder coat versus paint. Need to find a suitable gas tank, oil tank, left side cover and a few other items I'm sure. Much to my surprise, it has the complete tool kit in original bag and pad. It's probably worth more than what I paid for the bike.

No worries - I think we all enjoy any conversation that is Bridgestone related. I played golf Monday and turns out my caddie restores old bikes. Mostly Harleys, but we talked bikes the whole time.

Golf and bikes - 2 things my wife hates. But now back to our regularly scheduled program - my 175DT:

2 key items missing from this bike are the left side cover and gas/oil tank. Bike is 16E, so that gives it a May of 1966 birth date.

When did the 175DT go from the fuel tank being under the gas tank to having an oil tank on the side of the bike? My concern is I will end up getting the wrong tank.

Will the left side cover from any year fit ?

Checking the parts list, the oil tank change was made at 16K, so yours will be the early one and you can tell from the photos in Ebay ads when they have the oil tank under the gas tank, most vendors leave them together. You can also tell the gas tank as the notch at the front of the tank is much more pronounced for the oil tank filler neck.

The parts list also shows different left side covers before and after 16K, but I don't know what the difference is.

Was the pull out switch a factory installed item? Also, what type of handlebars did the DT have? Mine have a crossbar, but I havent seen a DT with crossbar handlebars in any pictures.

Hello DCR my 16F bike has the pull out switch which is a factory fitting there is still a label inside the cover saying if operating at speeds above xxx pull out ..... , the bike also has the oil tank under the fuel tank so yours should as well , the DT has no crossbar and i presume the hurricane scrambler did .... ?

Not much of an update but my basement workshop is now filled with 175 pieces. Garage area is too cold Frame and associated pieces were all blasted to bare metal and primed. Next step there is to get frame, swing arm, both stands, oil tanks and the lower bridge painted black. I sent the front fork trim rings and parts of the rear shocks to Shelbyville for plating. I know they come highly recommended by a lot of you, but I wanted to see what their work looks like before I send them the rest of the pieces to be chromed - plus budgetary restrictions are in play here.

Rear fender is the worst of all the chrome pieces. The chrome here has definitely seen better days.

While we are at it, any hints on salvaging this crank?
