I made Miller timing pins VM.1052 and VM.1053.

Thanks Papaindigo.

Best I can do by hand with analog calipers.

Miller 1052 - Intake pin

Hex head - 0.75" across flats
Overall length 2.96"
Shaft length (base of hexagonal head to tip including threaded section) - 1.76"
Shaft diameter of the thicker section - 0.315" for 1.39" of the above shaft length (Note diameter of threaded section is 0.391")
Shaft diameter of 1st step down of the tip section - 0.275" for 0.3" of the above shaft length
the final 0.08" of the above shaft length is beveled at something like a 75 degree angle to create a 0.2" diameter flat at the pin's tip - I presume this bevel is to help guide the pin into the cam pin hole and that the 0.275" section is what actually locks the cam in place hence that is the critical dimension.

Miller 1053 - Exhaust pin - identical except as noted below

Hex head - 0.58" across flats
Overall length 1.932"
Shaft length (base of hexagonal head to tip including threaded section) - 1.65"
Shaft diameter of the thicker section is the same but the length of that section is only 1.25" of the above shaft length.

Does anyone know the thread and dimensions of the crank locking tool - Miller VM.1089?
I don't want to use the 6mm Allen trick.

Squeeto, per Sir Sams corobotchicken on youtube vids, you can use at 1/4 inch drill bit and it will work great. That is what I did and if you pay attention to getting the slack out of the timing belt, the little extra movement in the crank will help with that. Also, on mine when I changed the timing belt, I could not get the crank tool in due to corrosion or junk on the threads but the drill bit did work .
great.

These are the dimensions of the locking pins that I have on file:

Drive up to Parksville and you can use my factory tools and garage. I need to do my belt PDQ as well.

Thanks for the invite but I made the crank locking pin today so I am set for tools.

you really don't need the crank. It's a PITA to get in the hole is in the front of the housing and it takes a while to get it in right

The threaded Miller crank/flywheel pin can be difficult mainly because the threads in the bell housing tend to be rather dirty if not bogered. On the other hand a long shaft 6mm or 1/4" allen key fits in there perfectly, in fact that's what the 05 FSM recommends and illustrates; the tip of the key can easily be used to "tap" around the flywheel hole to confirm that you are in the small flywheel hole and not one of the larger cutouts; and the short leg of the key gives you an easy visual of whether or not it's in straight.

Yes I know some use a drill bit but a) I'm more comfortable using the short leg of the allen key to determine it's in straight and b) I have visions of the drill bit accidentally getting "lost" by going all the way into the bell housing. Yes I know the latter is unlikely but I've experienced unlikely too many times for comfort.

I fixed this issue with a hex bolt (Allen) welded to the end.
It turns in very easily now.
