Replacing bearings
Page 22
When Dinco is lowered the rear roller is supported so that the arms (A) rests on
the lower pin (B).
1. Remove the bolts in each side of the flange bearings (C).
2. The packer roller/t-ring roller can be rolled away.
3. Loosen the pointed screws in each bearing and the bearing can be removed
from the shaft.
4. Mount new bearings loosely on the shaft. Roll the packer roller/t-ring roller
back in between the bearing plates. Bolt the bearings onto the these.
5. Secure the pointed screws with Locktite and tighten well.

T-ring roller
The t-ring roller has been designed with a centre bearing (plummer block) to
support the shaft.
1. Remove the plummer block in the middle together with the flange bearings.
2. When the bearings are free, lift Dinco. The t-rings and shaft are now free.
3. Loosen the pointed screws and remove the flange bearings.
4. Remove the t-rings in one side of the supporting bearings to change the
bearing.
5. Having changed the supporting bearing mount the rings. Please note that t-
rings are mounted so that they gear into each other making each other
rotate.
6. Mount in reverse order. Secure the pointed screws with Locktite.
Removing rings from the shaft can be quite hard. Try cleaning the area
between the rings and the shaft with a high pressure cleaner to remove dirt and
corrosion that may be present.

If Dinco cannot be lifted, it is possible to remove the scraper bar (A) and in this
way free the shaft and the t-rings (see "Replacement of scrapers").
