M18 Impact Driver. Model 2650 B55A. First of these models out
of the gate. The parts schematics are dated August 2008. I got it
exactly 15 years ago. (DSCF1313)
I posted here in September when I replaced the Steel Balls that fit in
the Anvil. (DSCF1314) Worked but didn't have it quite right. Blamed the
Compression Spring. Figured on getting a new one before doing more.
Within the Collet is a single compression spring with a washer and
retaining ring. Milwaukee used this sort of thing on up through
successive models at least till 2015. Evolved into this Compression
Spring with a loop bend that digs in beneath the Steel Ball ( 2024-06-11
1) A secondary light wire spring (not pictured) floats above this
Steel Ball
Compression Spring (DSCF1697) installation with these older models is a
real chore. If not for this mini-driver set (DSCF1702) I got at some
market stall in Pusan, Korea 33 years ago, I wouldn't have been able to
do it.
Anyone here who has one of these older models on up till 2658 or so;
(DSCF1706) the Spring #39 followed by the Sleeve #38, slips over the
Anvil #36. With the Washer #40 on top, you have to shove that spring way
down till it's within the Sleeve. Keeping steady pressure right there,
get the Retaining Ring #41 snapped over it. It looks like this (DSF1703)
Always wondered why near everyone refers to Steel Balls as "Ball
Bearings."
