Hello Everyone! I have a 93 ACTY Attack with a E07A engine. I bought the machine with the engine all torn down due to a broken timing belt that damaged the head. I'm trying to reassemble everything, but I'm not sure of the tightening sequence and torque values? I have the manual, but it doesn't contain this info. On the page that shows the head it states a torque value of 6.2-6.8mm, which is obviously missing some important units. Any help is GREATLY appreciated! Thanks, Ben
Likely a typo on the torque and should read 6.2-6.8 kg.m(44.8-49.2 ft lbs). Do it in two steps, half the torque the first time around then go back and do the final value. There are only 8 head bolts so i would use this pattern.
Thanks Old Machinist! I was hoping you would see this thread and have the answer. From reading in the forum, I think you're the godfather of the ACTY mini! Thanks again- Time to see if I can make this damn thing run now!
I have the FelPro head torque specs book and looked in it to see what the rest of the Honda engines get torqued to and how. http://olybrake.com/pdf/fel_pro_torque_specs_guide.pdf
Thanks, downloaded this great info on torque specs, can also use for my old BMWs. OldMachinist is a real expert on the Honda Acty, glad that I can learn from him many details.

Does anyone no torque spec for pistons and for the main bearings. Also does anyone no where I can get over sized connecting bearings I had a spun bearing and need to get my crank machined. I'm not sure of bearing clearance can find that spec but I have a bout a 3 thousand difference between cyclinders
First step is to measure your machined crank journal, as well as the con rod. A competent engine machine shop should be able to specify a bearing to fit, with correct specified clearance.
