timing

[jcarr]

Ok guys read a thread on here last night where a couple of guys were discussing timing and made mention of a kent moore j33300 and acouple other meters. As I work on ag and construction tractors fuel economy isn't on the front burner. Also I see mostly the itilian iveco and *** yanmar engines. We do all of our timing with engine off aligning timing gears and a dial indicator in the ip.

Can someone list some pros and cons of different timing meters that work on the idi motor. Model numbers would be good too.

I'm finding lots of info that suggest that our idi motors aren't to different from those I see everyday. I can't say that about my stroker.

Most of the timing meters you see discussed are now obsolete equipment where parts are no longer available.
The best is theFerret
Snap on makes a similar unit here for about twice as much, but I'd be leary of it since it has the same piezo clamp, but only one size available, which limits the units usefulness to a narrow range of engines, the Ferret has 2 other size clamps available aside from the one that comes with it ( which fits our engines )for use on other type engines.

One main advantage to the Ferret is that you can take an engine with a bosch pump like you describe with a dial indicator timing setup , and find one that is known to be timed properly and gather a pulse spec off it with the Ferret, then you can dynamically time them in the future with the Ferret and save all that fuss. Depending on the engine might have to rig some lines but still wouldn't be that big a deal., One advantage is it allows you to see if the pump and injection system is healthy. If the pump is buggy, or injector bad, line will jump all over.

So basically this meters convert the fuel pulse to an electrical pulse that a timing light can feed off of then you just shoot the harmonic balancer like you would a gasser.

Exactly. Then , since the line is on TDC, you use the advance feature on the timing light to determine where the advance reading is in deg BTDC.
