Pump Timing

[icanfixall]

I found this vid on u tube about the use of turn buckles for pump timing. I DO NOT SUGGEST USING THEM... The idea of using the throttle turn buckle is ok if you are using the timing light method to time your engine. But using the turn buckle to adjust the timing on a loose pump where the engine is running is dangerous. Should the wrench slip off when the pump is loose it crashes over to the adjustment locks and usually will snap the pump main shaft rendering your pump core charge worthless. So now you have seen a different way to adjust your timing. My rental meters do not come with the timing light nor the turn buckles. They come with the simplest way to time your engine. They are also the safest way to time. Many members here will share how they feel about the ease of timing you engine using any kent moore J33300 or J33300-A meter.

i thought the turn buckle was just to hold the idle @ 2k while your checking timing.
and a quick way to set the idle back to 2k while re-checking.
cant watch videos on this comp.... ill be watching it at work tomorrow

I don't know why you would need a turnbuckle to hold the 2000 rpm anyway. I just turn up the idle screw and re-set the idle when I'm done. If you don't want to do it that way a wooden wedge of the correct width between throttle arm and cold idle solenoid also works.

Rotunda did make a special throttle set tool for the timing rpm. I have one but never use it. Turning up the idle rpm is a great idea till you shut down the engine at 2000 rpm with a turbo. The turbo spins for a really long time with no oil pressure on it. I'm just not comfortable doing that. A block or wedge of wood is another good idea. Holding the rpm is the easy part of timing with a light. In the vid you can actually see the top dead center marks on the timing tab at the damper because the guy cleaned off the road dirt and marked it well. Also you see how the timing light adjusts and tells you what the degrees of timing are. This is how I used to time my engine. I had a snapon adjustable timing light. I gave it to a visiting member RLDSL when he was out here on vacation to enjoy in Vegas timing another members rig. Turns out he had some problems with the light. Found out when he got home the wires had broken for all the use it got before I bought it off ebay. He fixed it and I gave it to him as a favor to him fixing it. I was not planning to ever use it again. Have not missed it either. Sadly we don't see Robert posting much lately. For those that have no idea bout him.. He had the spicer aux trans inline with his 5 speed. So that 15 forward and 3 reverse gear to pick from...

I don't know why anyone would shut down an engine running at 2000 rpm. That would be not a good Idea. And not what I said to do.
Turn up idle
check timing
turn down idle
shut off truck
Its simple, holds idle steady, and takes 2 seconds to do

In the video the fellow proves the weakness of the turnbuckle advance tool technique as a failure when he slips it himself installing it.

SOMEONE LOG into youtube and post a comment correcting him of his idea explaining why!
