Well I have been stumbling with this for a while,.. here's the deal.When the engine is at tdc, and the pump is locked with the pin, lined up with the static notch and mark on the pump bracket.....I have the dial indicator preloaded about 3mm etc.. I turn the engine backwards and nothing shows on the dial indicator. I even put pressure on the dial indicator plunger, and it is bottomed out and not using the preload.... any how, if I keep turning the engine backwards, I can eventually get the dial indicator to climb NOT DROP...so I think that means the pump is built wrong ...it should be at max lift on the plunger with the engine at tdc..it seems to be at a flat spot between bumps on the plunger with the engine at tdc...hence when I turn the engine backwards, I get no moment until the indicator climbs up the plunger again ..but way back on the reverse engine rotation. The problem is how can it be assembled wrong?.. The plunger can't be installed out of time as it has a locating pin right?.. The key way is in the stock location and with the pully locked, the key way is facing toward the cyl head..weirdI am trying to figure it out... I used to have to jump a tooth on the pump gear to time it before, when I used it with my last 1.6TD. That worked "ok" but it never was right ...weird.. I had told Piers and they told me to spill port time it or use my piazzo setup.. That kinda was messed up too.. figure they would have me send it back and fix it for me .... no. I have not taken the pump apart to check it out as it was sealed by them. But, I think thats the only way to fix this problem correctly.Any ideas..??ThanksDeo\x/ Hillfolk!
