thall1 Posted November 12 Report Share Posted November 12 Starting to strip my 2013 4t.. gearbox issues…. Can’t get enough slack on the chain to remove the cam shaft! tensioner is removed… manual says just to lift the chain off the gears and remove the cam but I can’t get enough slack. also the retaining ring for the cam shaft bearing is slightly too long to come free of the retaining groove to allow the bearing to slide off?!… Ive even tried removing the guides from the block but they won’t come out either at this stage I must be missing something in the manual but I can’t think what?

thall1 Posted November 12 Author Report Share Posted November 12 I’ll answer my own post for future reference! the trick is to turn the bearing retainer clip so one end is above the bearing journal.. place a thin wedge ( I used a 6” rule) between the end of the retaining ring and the face of the head to stop the retaining ring from spinning… then use a good pair of pointed pliers to carefully prize/ lift the retaining ring clear of the bearing. Once it’s off you can remove to camshaft side bearing, tilt the shaft and remove the inner bearing then drop the cam down to lift the chain clear. Note: you will need to remove the water pump and the water pump shaft from the water pump drive gear and then slide the water pump gear out to allow the chain to drop down below the head and barrel and allow the head/ cylinder to be lifted clear. You need to do this prior to lifting the cam out as the cam train holds the water pump gear solid to allow the shaft to be undone. There is a special tool to undo the water pump shaft… I didn’t have one so used a stud extractor tool. It’s pretty tight so be careful!!
