Replacement Part Instructions
WARNING: Always unplug the machine before performing any repairs.
401/301: Detent, Channel & Channel Ring
Tools Needed: Electrician’s Tape, Allen Wrench (5/32), Lubricating Agent
Warning: Never adjust the detent hose clamp on the new detent. This will damage the new detent.
Models 401 and 301 purchased after 1997, serial numbers 8000 or higher allow the removal of the channel ring (B)
without removing the channel (E). Units older than 1997, serial numbers 7999 or lower, require the replacement of
both channel and channel ring. Serial numbers are placed on the rear flat surface of the can, under the control box.
1. Remove the Allen shoulder bolts (G) located on either side of the channel (E).
2. Pull off the channel/channel ring from the detent (D). If the channel ring (B) sticks, remove the detent hose
and follow steps 1-3 under Yoke and Detent Hose below.
3. If you are replacing the channel and/or channel ring only, skip to steps 7 and 9.
4. Remove the black electrician’s tape from the detent and detent hose (F).
5. Pull out the old detent and slide the new one (rubber side in) an inch deep into the detent hose. Make sure the
L shaped notch is facing up.
6. Tape the new detent to the detent hose. Make sure you do not cover the bleed hole.
7. Fit the channel/channel ring onto the detent until you get it just past the L shaped notch. Make sure the notch is
facing up. Reattach the shoulder bolts to the channel.
8. If the new detent does not fit into the existing channel ring do the following.
• Remove the breeze clamp from the old detent, do not adjust the breeze clamp on the new detent and attach
it about a quarter of an inch down from the tip of the new detent. Tightening this breeze clamp will shrink
the circumference of the detent so it will slip into the channel ring.
• In addition, you may lubricate the inside of the channel ring before inserting the detent. Do not get any
lubricating agent inside the detent rubber. Some chemicals can deteriorate this rubber.
• If you are still unable to insert the detent, sand the inside diameter of the channel ring until it fits.
• If you are not replacing the detent or the channel ring continues to stick, call Lob-Ster @ 800-526-4041 for a
breeze clamp. DO NOT FORCE IT.
401/301: Yoke & Detent Hose
Tools Needed: Allen wrench (5/32), Electrician’s Tape, Flat Head Screwdriver, Soft Mallet
Warning: Never adjust the detent hose clamp on the new detent. This will damage the new detent.
1. There are four Allen shoulder bolts (G) that attach the yoke (H) to the front of the machine – two on the top
and bottom and two on the left and right. Remove all four shoulder bolts.
2. Loosen the hose clamp located at the end of the detent hose (F) which attaches to the red can, allowing the
removal of the yoke, the detent hose, and the channel (E) as one unit. Leave the channel ring attached to the
detent.
3. If you are replacing the detent hose, you must remove the channel/channel ring from the detent (D). You may
be able to remove the channel ring (B) with simple pressure. If it is too tight, place the detent face down and
tap the ring off with a soft mallet or equivalent. The mallet is used because the plastic parts are easy to break
with too much force.
