Rotor Assembly of the 2510 wood chipper

We are excited to share more information on our chippers so potential customers can know more about our chippers and current customers can read these blog posts and gather useful information before doing any maintenance or upgrade on their chippers.

 

If you ever need to replace the rotor on your 2510 wood chipper, here is a quick guide on how to do that!. This guide also works for replacing the rotor on the 3514 wood chipper.

Step 1.

Tools needed:

 

- A pair of 9/16" hex wrenches.

- 1 pulley extractor

Step 2.

 

Parts needed:

 

We recommend that if you are replacing the rotor, it is also recommended to replace at least the bearing assemblies and bolts, to maintain the proper tolerance adjustment (interference) between the shaft and bearings and also guarantee the correct clamp load on the fasteners without risk of fatigue or failure.

Parts shown in picture :

 

1- 2510 Rotor

2-Bearing Housings

4- Bearing Spacers

2- Dirt Covers

8- 3/8" x 1-1/4" Grade 5 bolts

8 - 3/8" lock washers

8- 3/8" hex nut

Step 3.

 

First we introduce the shaft covers into each end on the shaft. Please note that the cover with a welded tube spacer goes into the the short end of the shaft.

Step 4.

 

The covers must be inserted with the bends facing outwards.

Step 5.

 

Insert the bolts from the feed side. Tip #1: To make more room to insert the bolts you may slide the rotor further back. Also, make sure to place a hex nut on each bolt so they don't fall inside the bottom chipper housing. Tip#2: If bolts do fall inside the housing, use a piece of cloth between the fan blades and rotate to comb the bottom until bolt is extracted.

Step 6.

 

Insert one spacer per each side of bolt. Insert the bearing housing with bearing. You will only be able to insert a little (given the strict tolerance of this part). DO NOT SAND the shaft bearing surface nor the inside diameter of the bearing. Make sure the bearing is aligned with shaft

Step 7.

 

Once the bearing is aligned with the shaft, hit from the pulley side to let the shaft slide inside the bearing even more, as shown in two pics below:

Step 8.

 

Here the shaft is now pre-mounted on the bearing... 

Step 9.

 

Once the bearing housing is aligned and pre-mounted with the shaft, grab a hammer and hit the inner bearing ring with a piece of pipe. WARNING: Make sure that the pipe is touching the inner bearing ring ONLY. If the pipe has bigger inside diameter, it may touch and damage the bearing seals. To ensure proper fitting, make sure the bearing's inner ring is touching the shaft outer step.

Step 10.

 

Insert the bearing housing on the pulley side. Again, because of the amount of interference between the elements, you need to solidly hit this with a piece of pipe and hammer. Remember we are pre-mounting the shaft onto the bearings. Sliding the bearing will also give you enough clearance to insert the spacers and bolts.

Step 11.

 

If you noticed last step, we omitted placing the spacers and bolts on the pulley side. Once the bearing housing is pre-mounted on the shaft, we will now install these...

Step 12.

 

Now we will hit the bearings further inwards until they touch the shaft's outer step on at each side. Once the bearings are touching the outer steps, we proceed to install lock washers on each bolt.

Step 13.

 

Tighten by preloading the bolts...

Step 14.

 

At this point, rotate the rotor slowly by hand (be careful, blade should not be installed at this point). Observe that rotor is rotating aligned with housing and that is not making contact with other elements of the chipper. If shaft makes contact with the dirt covers, you may adjust shaft height by softly hitting the bearing housing from the outside down up with a piece of wood and hammer.

 

Once the rotor is rotating freely, apply required torque bolt torque of 25 ft-lbs.
