mcbrat Posted December 10, 2011 Share Posted December 10, 2011 ea81. to replace the cam gear, do I need to split the block and remove the cam, or can it be replaced with the cam still in the engine? Quote Link to comment Share on other sites More sharing options...
6 Star Posted December 10, 2011 Share Posted December 10, 2011 Heres how mine looked going back together: It appears that the block will have to be split to get it off, the flywheel attatchment on the crank is in the way of the cam gear slipping off the cam. Plus it will be easier to get the cam gear off outside the engine. Although the Flywheel connector on the crank may be able to come off... not sure, I never attempted to take it off.

mcbrat Posted December 11, 2011 Author Share Posted December 11, 2011 figures.... I had a NOS short block shipped to me many years ago, and the packing job was less than stellar. I was looking at it the other day, and I noticed the cam gear has a crack in it... Quote Link to comment Share on other sites More sharing options...
ShawnW Posted December 31, 2011 Share Posted December 31, 2011 Id ask Ken or somebody at Delta Cam I bet they have to take them off to do the cam job. I have tried pressing them off and they don't like to come off. If you could break the old one off in pieces and order a new one I bet that would work fine.

GeneralDisorder Posted December 31, 2011 Share Posted December 31, 2011 I've had Delta grind EA81 cams and there is no evidence they pulled the gear off. None that I could detect anyway. GD Quote Link to comment Share on other sites More sharing options...
bheinen74 Posted December 31, 2011 Share Posted December 31, 2011 (edited) my extra ea81 cam sitting here, looks like there is a dowel from the front driven into the shaft, and that dowel look removable, from the front of it. so i would say it is possible. in fact, yes it is doable from what i know about dowel pins, and cotter pinch joints. It is a swedge joint from my look, so you have to grabe and hold the stopper, while to press and pull the gear off the cam Edited December 31, 2011 by bheinen74 Quote Link to comment Share on other sites More sharing options...
