I can only comment on how it is done on other diesels not Mercedes.

Liner pullers are usually made to match specific engines; so if you plan to make something be advised it has to have good fit and good alignment.

One type of liner puller consist of 2 metal plates witha big thick piece of rubber between the and a threaded rod going through the center to tighten the 2 discs and squeeses the rubber against the inner bore of the liner. A slide hammer is attatchd to the threaded road and hopefully the liner is slidehammered out. It is best to degrease the bore of the liner with brake cleaner and the rubber also needs to be kept dry. This type of puller usually only works on liners that are slip fit into the cylinder or "wet" type liners.

The more common type consist of a heavy plate that is machined to fit the bottom lip of the liner (it has to be a good fit and not be wide enough to score the bore of the block as the liner is comming out). There is a long heavy metal rod through the center of the plate that extends up and past the surface of the block. On top of the block is a metal tube (or a special frame work) larger than the liner diameter that is high enough for the liner to come completely out of the block.
(The place I worked at the just bought a couple sections of heavy tubing/pipe large enough for the liner to fit through and had them and the bottom plates sent to a machine shop. The used a metal beam that bridged the top of the tube, drilled for the alltread rod that attatch to the bottom plate and you turned a nut to pull the liner out.)
That is what I have seen used on Detroit diesel and Cummings engines. Except that Detroit diesels also have a liner puller that can go into the ports on the cylinder.
Back in the day there also was places that rented liner puller for trucks. Fore Mercedes???
It might be that a puller for Ford tractors or Perkins engins might work.
