Just a quick howto on installing the crank sprocket.



RED - 14mmx1.5?? threaded rod, about 8 inches long
GREEN - 2 nuts of the same threadpitch
BLUE - Large (30-38mm) socket, 1/2" drive
YELLOW - Feeler gauge

1) Insert threaded rod through the 1/2" square hole in the large socket
2) Rest crankshaft sprocket on the crank. Make sure crankshaft key is installed.
3) Thread rod into crank, using both nuts tightened against eachother to grip and turn rod.
4) Lube crankshaft with WD40 or assembly lube
5) Seize crank with a screwdriver or other solid object in starter hole, etc.
6) Tighten nut until the sprocket is about .09 - .1" from the oilpump housing
7) Pry the crankshaft towards the crankshaft sprocket and re-check clearances

This method will also work for installing the crank pulley but if you are using an impact to do the work instead of an openended wrench... you'll need a short threaded rod for the crankshaft sprocket, and a longer threaded rod for the crank pulley.

There are other less precise ways to do this (Use a BFH), discussed here:

im glad people like you take the time to make these diagrams. werd

lol fuck that.

heat it up with a torch and get a collar of steel, put it over the sprocket and bash it on.

two hits, sunk all the way on. no worries.

good writeup though :thumbsup. 2gnt needs these.

I always use the crank pulley and drive it on with that and an impact wrench.

Yeah, I used to do it that way Dino, but a couple people have stripped out their crank because the factory crank bolt doesn't quite thread in far enough to get a good grip. I have a huge impact wrench that breaks things so I got paranoid. Using a threaded rod ensures it's threaded all the way in to begin with, and the first thing to strip will be the cheap nut.

We always just pound it on with a copper mallet ("Thor") and if we're feeling cautious, we'll hold a big ass 34mm socket against it and pound that. Works every time and strips nothing. :shrug

Appreciate the info though. :thumbsup

I found out last time i did this that the long bolts in my engine stand are the same thread pitch as the crank bolt. Suddenly, it became much easier.

I basically did what was mentioned above. Got a 34mm socket and bashed it on with a mallet. I left about a 1/16 inch between it and the oil pump. I also smeared the crank shaft up with anti-seize before I put it on, that way if it ever needs to come again .... it should be easier. :rolleyes

this helps, but im still gonna go bug ya.
