burnout Posted April 19, 2007 Share Posted April 19, 2007 Hi, I am in the process of installing new contact points on a '74 DT175A. I have purchased 3 sets of points for this specific model and none of them fit. The rubbing block on the points will not touch the lobe on the flywheel, hence, I assuming, incorrect points. (no bump, no intermittent spark) The engine is original, numbers match, and the flywheel numbers are correct for this engine. I have elongated the attaching hole, filed points metal for clearance and still no rub on lobe. Obviously, I haven't gotten to the timing or points gap, yet. Any help earns eternal gratitude. Desperate! Many Thanks! Link to comment Share on other sites More sharing options...

Desperate! Many Thanks! you might have bought a set that doesnt fit your engine or the dealer sold you the wrong set. When i bought mines, on ebay, i had to grind a part of them since the flywheel could not rotate because of them. anyway, you seems to know what you are doing, so i might be just wrong set.

My DT 175 uses Part Number 443-81321-10-00, and the condenser is Part number: 277-81326-90-00 or Hitachi 617-214 the condenser can be hard to get, I have in the past fitted a condenser remotely under the tank, Hope this helps Link to comment Share on other sites More sharing options...
