Removing rubber feed rollers from planer

5/11/17

We need to change out the rubber rollers on our SAC planer. The rollers are supported by a six sided steel shaft

According to the manual you just remove a cap screw and washer then pull out the rubber rollers. There is also a larger metal element with two handles. This rotates but does not seem to pull out, even if we remove the little keeper that the pencil is pointing to.

Is there something else we need to do in order to expose these rubber rollers?

It is call a snap ring, you will need a special set of snap ring pliers, some sets open and other close to when squeezed activate.
I hope that helps

We have those special pliers and were able to remove the snap ring.

From there we were able to grab those black knobs and rotate the round steel part they are affixed to.

This, however, didn't appear to do anything. When we pull on them nothing happens. It is almost like there is another snap ring on the cutterhead somewhere.

Shouldn't this be able to pull straight out?

The shaft is most likely milled to receive the snap ring, this holds the shaft in place, the ring is most likely pinched between the two pieces of metal, either way it must come off in order for you the get the shaft out. Be careful not to bend the ring out of shape or you will have to replace it. They sell snap ring pliers with different sized pins that are interchangeable with a small allen wrench.
Good luck

Try Tapping on the shaft with a rubber mallet or small block of wood, it might be rusted from moisture.

In your statement it says "remove cap screw" when you turn the counterclockwise screw does it move outward from where it is? Or does the shaft and handles move together?

It would appear that the bearing blocks and rollers are meant to slide out of the machine as a unit at which point you can pull the bearings and blocks off the shaft and replace the rollers. You may not need to remove the snap rings at all unless the bearings are shot.

Is there a grub screw or other fixing that holds the bearing block in the surrounding casting? I suspect there may be a groove around the circumference of the bearing block that allows the rotation you see, and removing a pin or screw that engages the groove would allow for removal. Is there a parts breakdown that illustrates how the blocks are fixed in place?

It appears you have some new rollers ready to go in. Can the supplier offer any guidance?

I have sometimes seen bearing supports like that where there are screws instead of the two handles that you need to back off the lock nut and screw in to slide the bearing assembly off of a shaft. You might try that...

What model # planer is it? I would guess that the part with the handles has very fine threads on it and it will take a lot of turning before it is removed. The lock ring definitely is there to hold this piece in place.

The planer is a SAC RS63

As you can see from the manual it says we should only have to remove the top bolt and end bolt and then it should slide off.

I attached a youtube video of how the metal donut on the end rotates. We also took the black knobs off so the donut would spin freely. We rotated it a lot of times and it spinned freely but did not appear to be threaded into position.

As the video shows we also tugged straight out but to no avail.

Any ideas?

Judging by the written instructions and your video the top bolt holds the bearing block in the casting and the shaft is meant to be a slip fit in the bearing. I would guess that the shaft is binding in the bearing due to corrosion.

Try a shot of PB Blaster or 50/50 transmission fluid and acetone and let it soak overnight. Give the end of the shaft a tap with a mallet and wood block. If that fails, see if you can rig up a bearing puller using the threaded holes in the bearing block. A little heat judiciously applied might help to loosen things up.If there is access to the other end of the shaft, maybe you can drive it and the first bearing block out from that end. Use caution so as not to break the castings .

I think the snap ring is a red herring, it only needs to come out if you are replacing the bearing.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
