Sun, 13 February 2005 03:42 We used 18RC bearings and used the 18RG torque figures and it was hard to turn. I reckon that the new bearings are just firmer than the old ones (hence the need to run in a rebuilt engine) The other reason that it was hard to hand crank was that the bores had just been oversized for the new pistons and new rings. A rebuilt engine should always be harder to hand crank. This is also due to less lubrication. We had to use two batteries to start the engine (out of the car with fairly average connections) because we couldn't get it to go over compression. The torque figures should be fine. I've had a look at some of the other figures comparitively between the two 18R series engines and it seems that where the design of the parts is the same, it is only the parts relating to the crank and the camshaft drive gear (aux shaft) the use different figures. It seems though, that the RG uses finer tolerences for tightening torques. A few of the figures for parts of the engine are within the range set for the 18RC but the RG has a smaller range. ie. 18RC range = 68.7-83.2ft.lb, 18RG range = 72.3-79ft.lb I thought this was interesting, along witht he fact that 18GR's came with a 3-angle valve grind from the factory. You guys might not find interest in these things but then again, I lead a pretty dull life. [Report message to a moderator]
