Alignment of Engine

The chocks may compress 0.001 times the chock height when the holding down bolts are tightened.

per 10 mm of chock height align the engine 0.01 mm higher...but maximum 0.05 mm

Align close to the top of the allowed coupling tolerance Obtain satisfactory alignment and crankshaft deflections Check deflections after the job is finished when

temperatures have returned to ambient



Preparing of chocking area

Finish all welding on the foundation

All bolt holes should be drilled

Fit the reamer bolts inside before pouring

Check ship trim



Check all materials and tools are availableEPOCAST 36

Cleaning of chocking area

Clean the foundation fromrust, oil, grease, mill scale, paintNOTE: Epoxy Primer (20-25 µm)is allowed

For deck machinery a thin coat ofinorganic zinc or similaris acceptable



Damming procedure (Part I)

Insert the flexible damming betweenbedplate and topplate



Damming procedure (Part I)

Insert the rubber tube into thebolt hole



Damming procedure (Part I) Spray release agent slightly into

the mould



Damming procedure (Part II)

Tack weld front metal dam in place



Damming procedure (Part II) Seal the front metal dam with

sealing compound



Damming procedure (Part II) Complete the foam damming on

both ends of the metal dam



Damming procedure (Part II) Spray release agent to the

inside of the front metal dam



Mixing procedure

Add hardener according to mixing and pouring guide

into the resin can

Place the switched-off mixing tool inside the resin can



Mixing procedure

Mix the resin/hardener between 250-500 rpm

for 2-3 minutes

Switch off the mixing tool and take out of the resin can



Pouring procedure

Ensure that all damming is complete

Pour the resin shortly after mixinginto the lower end of each chock

Height of overpour for staticpressure should be min. 20 mm

Barcol hardeness test

Remove the heaters Remove the front metal dam

and rubber tube Check the barcol hardeness on

the side of each chockNOTE: min. 40 Barcol

Remove the wedges orback-off the jacking screws
