Head Torquing Sequence:

[Hal the Elder]

HELLO!

I know that the head bolt tightening sequence has been posted here before, in fact I read it again just yesterday.

However, I would like to have a new sequence posted for clarification.

I'm submitting a picture of Oscar's cylinder deck in the perspective and position I'll be usng for attaching the head.

On top, on the valve side, I'll call those bolts (left to right) A , B, and C.

The 10mm bolts (left to right), I'll call D and E

The next pair down (left to right), I'll call F and G.

The bottom Pair (left to right) I'll call H and I.

Now, please give me the proper tightening sequence, using my letter designation.

Thanks a Lot...
HAL

Thanks, Quenton!

Now to go to CTO and buy that set of ball-end long-reach Metric Allen Wrenches with 3/8" socket drive!

(CTO = Chinese Tool Outlet, or Harbor Freight!)

I went to Northern Tool and found a set of metric ball end sockets with the following sizes:

3
4
5
6
6.5
9
10

That's right, no 8mm. What the he**?

I ended up spending about $50 and bought a new S-K set on Ebay. They were cheaper than the Craftsman at my local Sears!

Hey Quenton:

I did as Moderator Jim suggested and bought that set of long-reach ball-end Metric allen wrenches at Harbor Freight, then removed the Gas Tank, and find that I can access only the 4 head bolts that clear the frame tubes on the right side.

The remaining 5 bolts are crammed under the twin frame tubes, and there's no way on Earth or any other planet that I can get in there even with the ball end-allen wrenches.

So it looks like I'm gonna have to shift the engine to one side or the other to get access with those other 5 bolts.

What's the best way to do this?

Thanks...

Wow Hal
That is strange. I can get to all of mine and Kilroy's head bolts without shifting the engine. I do have to go down between the frame tubes to get the one bolt (B on your chart) but I didn't have any problems. I'm very sorry my info did not apply to your situation. I'll be quiet now...

[Hal the Elder]

Heck, Jim...you didn't know! Don't beat yourself up!

Howl

I feel bad because you spent money on my recommendation and it turns out to be wasted money because my info was incorrect.

I have the receipt and the packing.

LOOKY HERE:

Only four head bolts are accessible with my torque wrench, on the right side of the engine.

SEE?

The other five are under the twin frame tubes and are inaccessible, even with the ball end of the allen wrenches!

To get to all nine bolts, my engine would have to be shifted THREE INCHES to the right.

I measured it!
