3-612-02-3510 3612023510 Sleeve Sechskantkupplung Tool For Homag Machine

A worn hexagon coupling sleeve shows up as slop in the drive: the hex no longer sits tight, the shaft rocks, and the machine runs loud or cuts off line. Replacing the sleeve restores the fit between the hex and the mating part, so alignment returns without touching the rest of the assembly.

This sleeve is an iron part, 24 mm across the outside and 41 mm long, with a 17 mm inner hole. It carries the Homag part number 3-612-02-3510 3612023510 and fits Homag woodworking machines. Confirm the fit by measuring the old sleeve on all three dimensions and matching the part number before you order.

Check the hex and the inner hole for rounded corners or bright rub marks, since those show where the sleeve has been moving. A sleeve that drops onto the shaft with no play at 17 mm is the right bore. Seated correctly, the sleeve holds the coupling centred through the 41 mm length.

Supply runs on the part number, so packing and customisation are not offered here. Send the Homag part number 3-612-02-3510 3612023510 with your enquiry, plus your measured 24 mm outer diameter, 41 mm length and 17 mm inner hole if you are replacing a sleeve with no readable marking. A photo of the worn sleeve helps confirm the match.

What the specification fixes, and what it leaves to the machine:

• Drive slop diagnosis — Rounded hex corners on the old sleeve show up as rock in the coupling, and a 24 mm replacement restores the tight seat the drive needs.
• Bore fit check — The 17 mm inner hole is the dimension to measure first, because a bore that is loose on the shaft will not hold alignment under load.
• Length in the stack — At 41 mm long, the sleeve spans the coupling stack, so measure the old part end to end before ordering a replacement.
• Outer diameter match — The 24 mm outer diameter sets how the sleeve sits in its housing, so check it with a caliper against the worn part.
• Iron wear behaviour — Iron wears at the hex faces first, so inspect those flats for bright polish or stepping before you decide the sleeve is finished.
• Part number identification — Order by Homag part number 3-612-02-3510 3612023510 when the old sleeve still carries a readable marking on its face.
• Seat check before fitting — Slide the new sleeve onto the shaft by hand first; a 17 mm bore that needs force points to a burr or the wrong part.

What changes on the shop floor once the unit is in place:

• Takes the slop out of the drive. A tight 24 mm sleeve removes the rock that shows up as chatter and off-line cuts, so the machine holds its position through the pass instead of drifting.
• One number to order against. Quoting 3-612-02-3510 3612023510 keeps the order tied to the Homag part, which cuts the chance of a wrong-size sleeve arriving at the bench.
• Three dimensions to check. Outer diameter, length and bore are all stated, so a fitter can confirm the 24 mm, 41 mm and 17 mm figures against the old sleeve in minutes.
• Iron wears predictably. The hex faces take the load and show wear first, which gives maintenance a clear visual cue for when the sleeve needs pulling.
• No guesswork on the bore. A stated 17 mm inner hole means the shaft fit can be tested before the machine is stripped down, saving a second teardown.
• Spare kept on the shelf. A sleeve this small stores easily, so a spare 24 mm by 41 mm part sits ready and cuts the wait when the coupling starts to rock.
• Simple hand fit check. Because the sleeve slides onto the shaft, a fitter can confirm the seat by hand before pressing, catching a wrong part early.

Check the three sizes against your old sleeve first: 24 mm outer diameter, 41 mm length and 17 mm inner hole. If all three match and the part number 3-612-02-3510 3612023510 matches your machine's parts reference, it is the right sleeve.

The inner hole diameter is 17 mm. Measure the shaft or the old sleeve bore with a caliper before ordering, because a bore that is off will not hold the coupling tight.

It is made of iron. Iron wears at the loaded hex faces first, so watch those flats for bright polish or stepping as the sign the sleeve is due for replacement.

The sleeve is 41 mm long with a 24 mm outer diameter. Measure your old part end to end and across the outside to confirm both figures before you order.

Yes, quote 3-612-02-3510 3612023510 with your enquiry. If the marking on the old sleeve is worn off, send the measured sizes as well so the match can be confirmed.

If the hex rocks by hand or the bore shows scoring, the sleeve is worn. A new sleeve should slide onto the 17 mm shaft without play, so test the fit by hand before pressing it home.

Send the part number 3-612-02-3510 3612023510, your measured 24 mm outer diameter, 41 mm length and 17 mm inner hole, and a photo of the worn sleeve if you have one.

No customisation or special packing is offered for this sleeve. Supply runs on the part number 3-612-02-3510 3612023510, so order against that number and the stated 24 mm by 41 mm sizes.
