Am I looking at this right, is 90% back of the main part milled to 3 different step heights? were this another industry I would call it chem milled. that was not the easy way out, no cutting corners here.  |
Yes, in this last design, I milled the back to 4 different thicknesses. IIRC the original bracket is approx. 175 thousandths inches thick. I made the part of the bracket that is bent and has the oval slot milled in, approx. 185 thousandths inches thick for extra strength. I milled the notch in the bracket where the bend is to keep it from cracking when I bent it on the press. The bracket body thickness is approx. what the original was. I milled in the radius for the lower alternator mount to accommodate any differences in the Denso alternator mount length. This probably was not necessary as Denso seems to have held pretty good tolerances. Then I milled in the flat where the new third bolt goes into the timing cover case. I tig welded on the 8 x 1.25 nut for the adjusting arm to try to stay with metric. The adjusting nut I had to mill down to minimum thickness and drill and tap. This was to keep the lower bolt head from sticking out into the belts. It probably would not be a problem but I was concerned that down the road when the belts got worn and the adjustment was out all the way; the belts might whip and be able to hit the bolt head. Same reason for the thin stainless steel washer. By the way that long adjusting bolt is stainless steel too so should last a long time and should not rust into the nut as easily. I machined the adjusting arm that has the slot in it, with a round extrusion to ride on the radius on the bracket and to help keep the spacing for tightening with the lower alternator mount. Grind, deburr, sandblast, powder coat, clean and re tap all threaded holes, assemble and good to go. Simple as Mud.
Good luck with the conversion and let us know how it goes. Just in case, the changeover should just be a bolt on but the big "B" terminal wire size should be increased and a suitable fuse added to replace the fusible link.
Sorry for the long post.
