DETROIT DIESEL 53

CYLINDER BLOCK END PLATE
A flat steel plate, bolted to the rear end of the cylinder block, provides a support for the flywheel housing. A gasket is
used between the block and the end plate.
Inspection
When the end plate is removed, it is essential that all of the old gasket material be removed from both surfaces of the
end plate and the cylinder block. Clean the end plate as outlined under Clean Cylinder Block in Section 1.1.
Inspect both surfaces of the end plate for nicks, dents, scratches or score marks and check it for warpage. Check the
plug nuts in the end plate for cracks or damaged threads. If nicks or scratches on the sealing surfaces of the end plate
are too deep to be cleaned up, or the plug nuts are damaged, replace the end plate or plug nuts.
When installing a plug nut, support the end plate on a solid flat surface to avoid distorting the plate. Then press the nut in
the end plate until the head on the nut seats on the end plate.

Install End Plate
1. Affix a new gasket to the end of the cylinder block (flywheel end), using a non-hardening gasket cement. Also apply
an even coating of gasket cement to the outer surface of the gasket (the surface next to the end plate).
2. Align the dowel pin holes in the end plate with the dowel pins in the cylinder block. Then start the end plate over the
dowel pins and push it up against the cylinder block.
NOTE: When installing the end plate, the heads of the plug
nuts at the top of the end plate on the In-line engine should
always face the forward end of the cylinder block.
