Добрый день!
у меня на JCB 3 CX, проблема такая, была произведена замена фланца переднего моста, который идет на карданный вал. После замены стал вопрос, как затянуть гайку, а именно каков момент затяжки гайки хвостовика переднего моста.
Кто сталкивался, подскажите, буду очень признателен.

Front Axle - SD55, SD70
Renewing the Pinion Oil Seal
The pinion oil seal 3 may be renewed without removing the
axle from the machine.
!WARNING
A raised and badly supported machine can fall on you.
Position the machine on a firm, level surface before
raising one end. Ensure the other end is securely
chocked. Do not rely solely on the machine hydraulics or
jacks to support the machine when working under it.
Disconnect the battery, to prevent the engine being
started while you are beneath the machine.

1 Remove the roadwheels and uncouple the axle
propshaft. Measure the axle rolling torque and record
the reading. Mark the relative positions of the pinion
shaft 4 and nut 2 with a scriber.
2 Using Service Tool 892/00812, remove the drive yoke 1
together with its stake nut 2.
3 Remove the seal 3 and fit a new one. Be sure not to
damage the seal housing. Pack between the lips of the
new seal with grease before fitting.

4 Check the sealing surface on the yoke for wear or
damage. renew the yoke if necessary.
5 Fit the yoke and temporarily fit the old stake nut 2.
Tighten the nut with a torque wrench, aligning the
scriber marks. Note the tightening torque required.
6 Remove and discard the old nut. Fit a new nut and
tighten to the torque determined at step 5.
6.1 Measure the rolling torque. The reading should be
0.5 to1Nm (0.37 to 0.74lbf ft; 0.05 to 0.1kgf m)
more than that recorded in Step 1 (see Note).
6.2 If necessary, progressively torque tighten the nut to
a maximum of 300 Nm (221 lbf ft) to achieve
correct rolling torque.
Note: If the rolling torque figure (new pinion seal fitted)
exceeds the reading recorded in step 1 by 1Nm (0.74 lbf ft;
0.1 kgf m) or more, or a minimum torque of 250 Nm (184 lbf
ft) can not be achieved then the pinion assembly must be rebuilt
using a solid spacer, see the apprpriate axle assembly
procedure.
6.3 Stake the nut using a square ended staking tool.
7 Refit the roadwheels and couple the propshaft.
