Installation:

As the new assembly has a machined o-ring groove it is susceptible to damage due to over

tightening therefore the instruction below must be followed:

• Clean the inspection cover with a non-scratching cloth as previous

• Position the window taking care to ensure the o ring seal is sat in the groove all the way

around before tightening.

• Tighten the bolt by HAND, until the plastic washer becomes trapped by the bolt head. Then

observe the relevant torque of 2Nm, if a torque wrench is not available then once the washer

is trapped the bolt head should be turned only ½ a turn more to tighten. The result in either

method is that you will see a witness mark through the plastic cover in the o-ring groove area

in respect of the seal turning from grey to black. This signifies the o-ring has created a seal

and does NOT require further tightening (see fig 21 below)
