Problem

Certain remanufactured crankshafts and short blocks for 1160 and 3208 Engines
and certain remanufactured 1160 and 3208 Engines need to be removed from
parts stock.

Action Required

Remanufactured Crankshafts
1. Inspect all 0R1211 Remanufactured Crankshafts in parts stock with date
codes prior to May 1, 1992.
2. Remove those with "MHT" stamped by the part number on a counterweight.
Remanufactured Short Blocks
1. Inspect all 0R0653, 0R0778, 0R0936, 0R1153, 0R1157, 0R2076, 0R3038, and
0R3686 Remanufactured Short Blocks in parts stock.
2. If "STD" is marked on the container box, or the date code on the
container box is later than May 1, 1992, do not remove it from parts
stock.
3. If neither of the conditions noted in Step 2 exist, open the container
to check the crankshaft size on the crankshaft-and-bore-size plate on
the right side of the block.
4. If the crankshaft size indicated is standard or .020" undersize, mark
the outside of the container "STD" or ".020 US", and return it to parts
stock.
5. If the crankshaft size indicated is .050" undersized, perform the
following test:
A. Obtain cupric sulfate from a local pharmaceutical supply house.
If unable to obtain locally, contact Spectrum Chemicals (1-800-772-
8786). Spectrum Chemicals will refer you to a distributor in your
area. Order C-1425 in the 1 lb. container ($25.00 is the minimum
order). (Mention that this is a one time order.)
Mix 1 gram of the cupric sulfate with 10 milliliters of distilled
water to yield a 10% (in water) solution.
B. Use a dropper to apply one or two drops to a clean machined surface
on the exposed rear flange of the crankshaft. If the solution turns
reddish brown or copper color in less than 10 seconds the
crankshaft is acceptable and the shortblock should be returned to
parts stock. Stamp "D" on the crank and bore size plate and also
mark outside of container ".050 US D"
C. If solution does not turn color within 10 seconds, remove the short
block from parts stock.
Remanufactured 1160 and 3208 Engines
1. Inspect all remanufactured engines in parts stock with identification
numbers within the ranges listed below:
5CD1-6882
57V1-34406
9WC1-836
62W1-70620
93Z1-8828
Check the following engine arrangements for the identification number ranges
given.
0R0688 0R0976 0R1094 0R1099 0R1152 0R1156 0R2819
0R0776 0R1092 0R1095 0R1150 0R1154 0R1777 0R2875
0R0975 0R1093 0R1098 0R1151 0R1155 0R2818 0R3231
2. If the crankshaft size indicated on the crankshaft-and-bore-size plate
is standard or .020" undersize, do not remove the engine from parts stock.
3. If the crankshaft size indicated is .050" undersize, perform the test
described in Step 5 above.
4. If the cranshaft passes the test, stamp "D" on the crankshaft-and-bore-
size plate on the block, and return the engine to parts stock.
5. If the crankshaft does not pass the test, remove the engine from parts
stock.
