ok, this is starting to make sense for me now, thank you. i knew there had to be a way to do the timeing withount having to give the snap-on man any of my money. i'm getting a tranny rebuild soon, and will be looking for some more power afterwards. just injectors and a turbo, as well as a little timeing. i've read that about 15.5 advanced is a good place to be. any sugestions to the contrary? i'm only looking for 350-400 hp, using a new, but stock, head gasket and bolts.

don't you still need special socket to break loose?
sure wish you could post a picture of diagram...

I will make this a simple as possible for you, but yes you can time the motor without a kit.
the pump can slip time, but you can find the stock timing on it via the pin. when it slips time it is only slipping on the gear.
pull the plug out on the side of the pump and bar the motor over, using a mirror bar it over until the pin comes up in the center of the window. you can turn the pin around and hold the pump in place, but this is stock time on the pump.
now pull the gear and bring the motor to tdc. once you have done this the motor will be back in stock time.
you can use degree tape or some math knowing the dampner is about 29 inches. and back it up the degrees desired. and inch is roughly 10 degrees. once you have it where you desire pull the pin back out to prevent breaking it when you torque the gear.
This is how I time them, and I have checked them with a timing light to make sure and Im no less than .5 degrees off. (the timing light measures the pulse of the #1 injector line, and a mark i make at tdc on the dampner and gives you exact timing as the injection event occours. pump timig can be effected by oversize injection lines as well)

The only special socket you need is a Delivery Valve socket to remove the DV holder, and that is if you're gonna go the dial route. Going off the damper, sounds like you'd only need a puller to do it, besides the usual tools.

you can time it with nothing more than a gear puller. it has been done that way more than a few times. turn the motor over till you pin the pump, then pop the gear off. then pin the motor. make the dampner, un pin the motor and back it up the # of degrees you want to add to the stock timing.

that sounds pretty straight forward... but what do mean by pin the pump? pin the motor?
no problem to backup crank to 16 degrees or whatever with degree wheel.
that is once I figure out exact spot TDC and pump aligns up at.
sure would be cooool... if I didn't have to buy the snap-on timing kit.

you don't want to back it up 16 degrees, if it is a 180 pump factory would be 14 degrees, motor pined/pump pinned. do a search on pinning the pump amd or motor. that is how the factory sets the timings. and i do't want to type that much.

Here's my home made timing kit. Less than $60 (not including the barring tool, since none of the timing kits come with one), and $10 of that was spent on a drill and tap for a set screw. Standard dial was $21, gear puller was $25 (could've used a $6 one), and borrowed the DV socket. I'm gonna use the metric dial on top of the standard one so I don't have to do any conversions. Metric dial isn't deep enough, so thats why I bought the standard dial. Could've done it for less than $40 had the metric one been long enough. I'm pretty sure I've got everything I need, and I did it for 20% of what Snap-On wants for a kit.

thanks.. did a search and found out what motor/pump pined means.
mine is a 97, is factory pinned settings 14.5 for a 97?
assuming that's correct, I'd need to set back 2 degrees to reach 16.5
is there any other tool you can use or make to avoid buying the DV socket? if I go the dial indicator route..

You could probably use a good strap wrench, but I'd hate to wreck on of the holders. The DV socket is around $40. I'm gonna bet that a DV holder is gonna cost more than that. If I didn't get a DV socket from a friend, then I would've just bought one.

a pair of vise grips matches the serrations very well. but it has to be a set with the oval shaped jaws. but this is getting real hillbilly now.
a 97 auto will be factory timed at 14.5, a stick will be timed at 12.5.
