So, are they still available.

Not unless someone reuploads them.  The photos in the maintenance guides are safely hosted, peoples own pictures are not and are subject to their own hosting.

I came across a similar thread with a picture of something Nick W knocked up to hold the crank pulley while undoing the bolt. It may be of some use.

Thanks YZ250, I am already assembling things back after changed 5 oil seals. I will make  bars on both sides of water pump and bolt them together.  Right side is ready. Need is to lock crank sprocket while tightening the  center bolt. Wanted to see how others locked it. In the end I install timing kit and new pump.

Ah nice one.    I see from the photo that you are already on the case, so well done.  I was looking for a purpose made bar and came across the one below that could be modified but no need now as you’re sorted.

Thanks, that tool would be ideal, saw also machined flats in sprocket and thought to have some kind of big open end spanner (67mm) to hold it. GM might have special tool for this.

Hopefully you used the ACTUAL timing lock kit. This includes, not entirely surprisingly, a crank locking tool.

If you didn't then you run a reasonable chance of it going bang when you start it. That said if you didn't remove the cam.covers, you're already looking at re doing the cam seals.

The tool suggested above was purely for holding the crankshaft pulley while undoing the really tight centre bolt. Polilara has changed the crank seal now so once tightened the makeshift bar can be discarded.

The tool in the timing kit is more of an alignment device than a locking tool for the monstrously tight crank bolt - it will be badly damaged if used for that. The gadget Polilara has ought to be enough to tighten the bolt to spec.


I tend to agree about not removing the cam covers; it's only a few minutes extra work once the belt is off, and you'll know that the seals are correctly fitted.

Thanks for all comments. This case was just to install new timing kit after 300 000km. As five oil seals were wet I changed them. I used old cam bolts and tightened them by using universal tool as shown in Haynes, so without removing cam covers. I believe that I succeeded well with those seals and they sit properly and do not leak. Let's see. To D.G's first comment I want to inform that before removing the timing belt I aligned all timing marks, locked cams, removed belt and turned crank timing mark to 4 o'clock to be able to rotate cams when working with sprocket bolts. Below is fig of my locking tool when tightening the old crank sprocket bolt. Bolt is now in 120Nm. I think that I install new timing kit before I continue to 250Nm etc. as if my lock fails the cams will follow...

Job jobbed, let's see how long it works, no leaks yet.  Thanks for all tips&comments.
