Engine block rebuild/timing

Hey guys.. I know it's been a month but I just got my block and head back. Looks great. Gotta do some more cleaning then reassemble.

The question I had is.. when putting on the fiber cam gear and crank gear on (static timing not chain), how do I time it correctly. I assume I have to time out a valve and piston to the proper position... I just don't know where to start...

thanks! :unsure:

Knowing where top dead center is on the compression stroke doesn't come into play when installing the timing gears. That along with knowing which is compression and exhaust stroke only comes later when installing the oil pump, distributer and adjusting the valves. But there is more to know than just how to put the gears on. For that part alone both camshaft and crankshaft gears have keys that holds them in position and by turning them to aline the dots as shown on the picture in this l-head engine in the service manual from fig. 32 on Bruce Agans website.

Take special notes of the thrust plates, washers, and spacers etc. and how important it is that all of this stuff be in spec.

From here there's a lot to do and a lot to learn even on these simple engines as I found out myself so read and learn anything and everything you can find.

Torques
Timing
Setting valves
Lining up the shaft and installing the oil pump
Proper installation of the distributer
Especially note everything you can read about installing the rear main oil seal if the crank and bearings havin't been installed. That can be a major trouble spot.
Make sure the crankcase isn't binding after bolting everything up.

I didn't want to leave you completely hanging but it's scary for me because of perhaps the consequences of catastrophic failure over something I might say. Luckily there's a lot of sites including this one with better information on the actual rebuild process than I could give. Haven't checked lately but there may be information on U-tube too.

What I can and will be glad to help you with is in finding some of the same information and advice that I found both here and other sites that I used when rebuilding my own engine. Way over a year ago I might add and as yet uncranked until hopefully late spring or early summer when I get a opportunity to continue restoring my DJ.

COMING SOON!!!
