Can anyone give me the dimensions of the spacers that are used to torque the jugs to the case without the heads to measure piston to deck height.

[HD Street Performance]

I use some old wrist pins and the long bolts. Just need 2 and don't torque them to full torque. Cutting PVC pipe will work too. Sorry I don't have dimensions.

Thank you Don. I had brass pipe nipples in mind trimmed to the correct lenght, but if pvc is strong enough then that is easy too

I manufactured about a dozen or so, shouldered nuts, here, many years ago to allow those to be clamped in place while the heads were off.
BTW, Snap-On has something semi-similar.

Thank you Scott. I have to spend 40 hours in our machine shop at work next week for my yearly recert and that building a set might kill some empty time slot

[HD Street Performance]

They just have to work, no need to get fancy. Use schedule 80 pvc nipples, may get lucky and not have to cut them.

Don't remember the dimensions.  In fact not sure I ever did much more than just hold up a piece of plastic and mark it but the plastic pipe will work fine.  Never used anything fancier.

Thank you all. PVC it is

When you do it every day, good tools make it so much nicer.

Buy a extra cylinder head bolts and machine them down run a copper or aluminum washer.. I had a bunch of old head bolts, trimmed them down and used copper washers works nicely . Or the PVC route ..


Or build a bridge to allow the indicator to slide into. Plenty of guys have done that as well.. For a HD if you use the stock bolts and two spacers under it with a hole on the edge of cylinder and one for piston you have a one in all tool. There where some nice pics posted of a few different bridges,,  I have a aluminum bar stock and use the stock outer bolts with spacers. That pic of just from google as i do not think i have a pic of the one I built set up. but you get the idea.

Lets see what your spare time builds

A bridge is a piece-o-cake to manufacture.

I made mine 1.375 and use the short bolts.  The diameter started bigger and got cut down a couple of times for bigger bore stuff.  The final dimension now is .837 and does work for the 131 TC engine I assembled.  Looking at a stock TC head.  The casting is about 1.4 something thick on the plug side of the head.

I am guessing that the major diameter is a piece of 1"? The .837 diameter looks to be cut back about the thickness of you caliper blade..... .125 or so?

[hrdtail78]

Yeah, it is 1.25 at the big part.  Only reason for that was, that is the scrap round stock I had.  I saw no benefit of taking the time and doing more to it than the step I made.  Which is .125 deep.  Plenty of room for any piston coming out of the hole.

Thank you. I bet I have something close to that next week. Then guess I will have to figure out what to do with them.....lol
