The information in the Service Bulletin will prevent the grain leakage from the front side of the grain pan on units that have a self-leveling cleaning shoe.
On certain units, there is a possibility that the grain pan seal on the front side was incorrectly adjusted by NEW HOLLAND during the factory production process. Consequently, this may lead to grain leakage from the front side of the grain pan. The leaked grains can then be found on the ground, the traction beam, and the top of the transmission.
To rectify this issue, the following steps need to be taken:
1. Check the grain pan seal to identify any potential misadjustments.
2. Correctly adjust the grain pan seal on the front side to ensure proper sealing.
ACTION
This correction should be implemented on units with a product identification number starting from 1965 onwards.
SERVICE
In order to prevent grain leakage and subsequent damage, it is crucial to carry out unit preparation as follows:
Unit preparation
NOTE: The four reference points to the unit are the left-hand side, the right-hand side, the front of the unit, and the back of the unit. These reference points apply to someone that faces the direction of travel from a standing position that is behind the unit.
WARNING
Avoid injury!
Before you start any work on the unit, prepare the unit according to the following instructions.
Failure to comply could result in death or serious injury.

Service instruction
1.Open the stone strap and the pivot plate.
2.Clean the debris.
3.Turn the cleaning shoe manually until the grain pan is in the fully forward position.
4.Check the distance (a).
If the distance (a) is less than 2 mm (0.1 in), proceed to step 5.
If the distance (a) is more than 3 mm (0.12 in), proceed to step 8.
NOTE: The distance (a) is between the start of the curved section (1) on the front face of the grain pan and the tip (2) of the grain pan seal.
5.Loosen the bolts (3).
6.Slide the brackets forward until the distance (a) on both sides of the grain pan is 2 mm (0.1 in).
7.Tighten the bolts (3).
8.Turn the cleaning shoe manually until the grain pan is in the fully rearward position.
9.Check the distance (b).
NOTE: The distance (b) is between the tip (4) of the grain pan front face and the tip (5) of the grain pan seal.
10.If the overlap (b) is more than 15 mm (0.6 in), the adjustment is correct. Proceed to step 15.
11.If the overlap (b) is less than 15 mm (0.6 in), loosen the bolts (3).
12.Slide both brackets (6) toward the rear until you reach a distance (b) of 15 mm (0.6 in) on both sides of the grain pan.
13.Tighten the bolts (3).
14.Return to step 5 to verify the distance (a).
15.Turn the cleaning shoe manually until the grain pan is in the fully rearward position.
16.Measure the distance (c).
NOTE: The distance (c) is between the tip (7) of the grain pan front face and the indicator on the location (8).
17.If the distance (c) is 18 +/- 1 mm (0.7 +/- 0.04 in), and equal on both sides of the grain pan, no further adjustment is necessary.
18.If the distance (c) is not equal to 18 +/- 1 mm (0.7 +/- 0.04 in), loosen the bolts (9).
9.Adjust the grain pan seal until the distance (c) is equal to 18 +/- 1 mm (0.7 +/- 0.04 in) on both sides of the grain pan.
20.Tighten the bolts (9).
