1 Mounting sterntube 安装尾轴

Drawing 538224-213-261 shows the instructions for alignment of the sterntube.图纸213-261有尾轴对中说明。First make the line with a steel wire. Most important is that the line is parallel to the engine girder at the sloped part (fr. 5 - 6,5).首先拉钢丝绳，最重要的是保证钢丝绳要平行与主机座倾斜面，（Fr5-6.5）

—The line should also be 50mm off (above) the topplate of the engine girder as indicated on the drawing. Deviation may be between +0 and +10mm, not less than 50mm above the topplate.

钢丝绳在主机座倾斜面处还要高于机座50mm，偏差在0—+10范围内，不要小于50mm.

—At the penetration through the hull make a small hole (between fr. 3 - 4), just to fit the line at least not as big as the sterntube. 在穿孔位置开小孔。

If the line is made, define the penetration according the sterntube diameter. Make the hole.

轴线定位后，划线开孔。

Remove the wire

The sterntube can now be inserted through the ER hatch. Lift over fr.5 and penetrate through the oval hole in fr.4. and the hull. 安装艉轴管。

Put the wire back through the sterntube and check again the alignment. 重新拉钢丝绳，检验尾轴管的对中。

Align the sterntube according to the line 根据钢丝绳对中艉轴管。

—Make sure that for the 538224 and 538225 the sterntube will be positioned according to drw

538224-213-262. The other yardno's to be positioned acc. 538224-213-260

—Also make sure the sterntube is positioned in longitudinal direction according the dimensions in

drw 538224-213-261 (115 fore of fr. 4) 尾轴纵向尺寸由图纸538224-213-261确定。

—Use the fixing plate (detail 1 drw 538224-213-261) to weld the sterntube in fr.4

安装Fr4处的封板。

—Make a construction to align the sterntube and fix it during welding. Outside at the hullplate and inside on fr.4. 在船体外板处和Fr4处各制作一个工装，用来在艉轴管的焊接过程中检验和调整艉轴管的对中

—Weld according instructions. 按照213-261的焊接顺序焊接艉轴管。

During welding check the alignment and make sure that at the end the deviation at the flange and the bearing house is not more than 1mm. If it is more than 1mm, please call to see if corrective measures are necessary. 在焊接的过程中，要检验对中，并保证法兰处的偏差和轴承座处的偏差不大于1mm,如果大于1mm,请复查。After the welding procedure the sterntube can be cut off according drawing 538224-213-260 and 262

艉轴管焊接完以后，可以根据图纸213-260或262切掉艉轴管超长部分。

—As on drawing 538224-213-261, cut off sterntube with overlength of 5 mm outside hullplate.

—Check total length (bottomside sterntube) according drawing 538224-213-260 (806mm)

—Make sure to make the radius of 70mm as drawing on 538224-213-260.

Now the stuffing box can be installed

至此，可以安装艉轴管盒子了（图纸为538224-111-100-A）。

2 Mounting V-strut.安装美人架
