Just got done replacing 5 bogie wheels on the half-track (one cluster of 4
on the driver's side and one single wheel on the passenger side that was
looking pretty rough).
I found it absolutely essential to compress the volute springs on both
sides, but I only had to release the tension (big adjusting nut on the
spring) on one side. I used a large "track-jack" and some very big wood
blocks to get the back end completely off the ground so that each track was
suspended in the air and could be moved easily.
Following the advice in the TM, and since I don't own the "volute spring
compressor tool," I used two 12 inch long pieces of standard thread (not
fine thread) 1-inch all thread. Believe it or not, the TM actually provided
these dimensions and very good and detailed instructions on the procedure
for compressing the volute springs: 1. remove top roller (under the roller
are two holes that fit the all-thread perfectly), 2. screw the all-thread
down into the holes, then 3. take a nut that fits the all-thread and screw
it down, which compresses each spring individually and eventually pulls the
crab up and off of the suspension arms.
I want to thank Nigel and the many other list members for the advice,
especially about working that big nut on the track tension adjuster. In the
bogie wheel install, I did release the track tension completely on the
driver's side to remove and replace an entire cluster of 4 wheels; however,
on the passenger side, I did not have to release the track tension at all,
as I was replacing an "outside" wheel that didn't require removing the
entire cluster.
