RD4 4G132 Combustion Chamber Advice needed

I had my rd4 head redone las year and left the chambers in.machine shop said leave them in.good luck

Also the copper washers on the bottom of the chamber are shaped with a bevel or diamond shaped, <>, they seal better than the flat washer. The chambers have to be snuggly drove in too. The only thing that holds them down is the two studs beside the chamber, so torque those evenly, @ 40 ft lbs +-

This is the tool used with a bridge support. That top thick washer is actually a bearing next to the nut for easier turning.

Thanks for the reply! realy good information.
The tool with the bridge support looks like the camber is in 2 pices?
So it takes the top half off and than you have to unscrew the bottom side??


Thanks Niels

No, it's one piece that drives in. Pull it using the threads

Yes the bridge support and the threaded puller are two separate pieces. The bridge support sets down over the two studs. The bridge can also be made out of heavy wall tubing and a plate with hole in the center. Now the one i made [in yellow] threads into the prechamber and the long bolt goes through the hollow hyd ram, the ram sets on the bridge then.
