During operation, there are cases when a crack occurs in the sleeve

When a crack forms, bubbles appear in the expansion tank

We determine in which cylinder the liner crack has formed as follows:

Drain part of the coolant.

Remove the air intake manifold.

Urgent replacement of Kamaz sleeve

Fill the coolant at the level of the holes in the heads.

We start the diesel engine and see which hole in the heads the bubbles start to come out of.

Where bubbles appear, there is a microcrack.

You can quickly remove the sleeve as follows:

Urgent replacement of Kamaz sleeve

Dismantle the cylinder head.

Urgent replacement of Kamaz sleeve

Using an ax and a hacksaw, we make a chock of a smaller diameter.

It should fit freely into the cylinder liner.

The height should be approximately 100 mm. We split it in half.

We make a wedge from a suitable board.

Urgent replacement of Kamaz sleeve

Turn the crankshaft so that the piston goes down.

Insert our device into the sleeve.

Urgent replacement of Kamaz cylinder liner

We drive the wedge. (Operations shown on removed engine)

Turning the crankshaft, the piston, resting against our device, pushes the sleeve.

Urgent replacement of Kamaz cylinder liner

We install a new sleeve and assemble it in the reverse order.

It is possible to change the sleeve on an installed engine without removing the sump. To do this, on a new sleeve, you need to make a call on a lathe so as not to break the rings.
