HHP-2 Bearing Cup Press
• Accurately aligns and presses 1-inch, 1-1/8 inch, and 1.5-inch headset
cups and races.
• Presses bearing cups and cartridge bottom bracket bearings into one-
piece (also called “Ashtabula”) bottom bracket shells.
• Holds fixed cup wrenches firmly in place when removing or installing
drive side (fixed) cups from threaded, adjustable-type bottom brackets.
Assembly
Thread and fully tighten handle knobs #526-2 onto handle ends of handle
weldment #526.
Pressing headset cups into frame
1. Determine the acceptability of the press fit between the headset cup and
the head tube. Using a caliper, measure outside diameter (OD) of pressed
portion of headset cup. Next, measure inside diameter (ID) of frame head
tube. Due to possibility of ID being out of round, measure in at least two
places and average the dimensions. Subtract inside diameter from out-
side diameter to determine amount of pressing interference. Normal in-
terference is between 0.1mm - 0.2mm. If the press fit is more than 0.2mm,
damage to frame and/or tool may occur. In this case, it is recommend-
ed to ream the head tube or find a headset with a different press interfer-
ence. If the difference is between 0.0 - 0.1mm, a Loctite-type adhesive is
recommended. If the difference is negative, a different headset is recom-
mended. Check with headset manufacturer for interference specifica-
tions unique to their headset.
2. Optional cup guides #530-2 are used to maintain cup alignment while
pressing. Cup guides fit most 1-inch and 1-1/8 inch standard headset
cups. Before using cup guide, insert guide into cup. If guide appears to
jam or is a tight fit, DO NOT use cup guides for that particular headset
cup. Simply press using threaded press plate and sliding press plate (to
insure alignment when not using cup guides, pressing one cup at a time is
recommended). Use care when pressing aluminum head cups; pressure
on the outer rim of the cups may result in damage.
Note: Do not use cup
guides if guides press on any pre-installed cup-bearing unit (ex. Chris
King
®
headsets).
3. Assemble HHP-2 and headset parts as seen in Figure 1.
4. Turn handles clockwise slowly and inspect alignment of cups as they en-
ter head tube. Press cups until fully seated into head tube.
5. To remove HHP-2, unthread handles and press lever of sliding press plate.
Pressing bearing cups into one-piece bottom bracket shells
1. Engage sliding press plate to highest notch on hex shaft.
2. Assemble parts as seen in Figure 2 (#530-2 Cup Guides are not used in
pressing “one-piece crank” bearing cups).
3. Turn handle clockwise and press cups until fully seated into bottom
bracket shell.
Removing and installing bottom bracket fixed cups
The HHP-2 can be used to hold bottom bracket wrenches firmly to drive side
(fixed) bottom bracket cups. This prevents wrench from slipping on cups due
to shallow engagement. Remove spindle from bottom bracket and assemble
HHP-2, fixed cup, and wrench as seen in Figure 3.
