Key to codes

  (*) =should be one of the below
  (*dk) = Don Kuzmer
  (*mb) = Morrie Burkeman
  (*bb) = Buz Bauerman winch deal
  (*jp) = Jim Plumley
  (*DP) = David Price
  (*RB) = Ron Bunting
  (*SC) = Steve Clift
  (*CB) = Carl Bock 541-954-4539 Puyallup, american sawmill
  (CM) = phase converter guy
  (ics) = Inside center shelving
  (is) = Inside shelving
  (iu) = Inside upstairs
  (iw) = Inside warehouse
  (ky) = Kuzmers yard
  (oec) = Outside east containers
  (ofs) = Outside field shelves
  (of) = Outside field
  (op) = Outside parking
  (ot) = Outof town
  (owc) = Outside west containers
  (oec) = Outside east containers
  (out) = Outside under tent

5/15/02  added location scheme for inside warehouse.  Not too accruate but should get us close
1-36 squares in our concrete slab.  1 starting from NW cornor  36 is SW cornor
numbered right to left top to bottom just like a book.  followed by paces/yards over then paces down
(means that numbers cant be over 6)   The dot in the table is at location 21,1,5
If this was a electric motor owned by Kuzmer its code should look like (isdk21,1,5)  if it is something upstairs
then it would look like (iu21,1,5).   For now we aren't going to worry about if it is high on the shelf or on the floor
we will just expect a small item is high and big items are on the floor.
New zones added summer of 03 for location of motors and stuff. see Autocad drawing for a map

  Detroit Blocks

Blocks, Inline 71 are lowblock, highblock and N series
lowblock has different head gasket, curved at top, no perimiter o-ring
highblock, new head gasket style, not as curved at head gasket area, Square block cast trademark
N series, air ports are 1 1/8" tall, circular trademark on side of block??

Blocks, Vee 71
dry block is older, large airbox covers on the sides
wet block has small cast aluminum airbox covers

  Detroit Rotation

Starter motors:
53 series have smaller teeth 12 each.
71 series have 11 teeth ??
RH starters have a RH sprial on shaft (older style starters)
A RH starter will drive in the clockwise direction so if you try to rotate it clockwise (looking at it from the gear end) it should slip or ratchet or dissengauge

its most normal to talk of rotation standing at the rear of the engine but not the case for detroit. Most engines standing at the rear will rotate counter clockwise or Left.

R engines turn CW when looking from FRONT of engine and use a RH starter motor, L engines turn CCW from the front, they are odd balls for most equipment, used mostly in marine engine pairs. Things like blower and exhaust manifold as well as cylinder head location are identified from the REAR of the engine

  Propellers If you can't achieve max engine RPM-- you need less pitch. If you are over revving the engine-- you need more pitch. Smaller pitch gives greater acceleration, lower top speed, less load on engine, Larger pitch gives higher top speed, loads engine more and slower acceleration, 3blade props slightly greater top speed and are less expensive. 4 blade props give greater acceleration and are more effecient over the long haul.
