<div> <font size="2">If we're talking (typing) about the oil pump/distributor drive gear end float being excessive, agreed, no shim, something is worn, identify the problem and correct it.</font></div>
<div><font size="2">Obviously the gasket thickness is a big part of the equation.</font></div>
<div><font size="2">Wear would most likely be obvious on the top face of the bush or the thrust face on the bottom of the pedestal.</font></div>
<div><font size="2">When I set these up I usually trim a little off of the bottom of the pedestal mounting flange to get the correct end float and bolt it up metal-onmetal, no gasket.</font></div>

<div>Hi - if the bushing is worn, it needs to be replaced. I would not run the gear with a thin shim under it, the shim will not last. I just looked at Moss and they have that distributor bushing listed for $75 plus or minus.</div>

<div>If you have slop with that distributor drive, you will never get the ignition timing to be rock solid.</div>

<div class="yiv7706464624MsoNormal">On page 1.130 and 1.131 of the Workshop Manual it describes the procedure for obtaining the correct clearance or float for the distributor gear driven by the camshaft. It gives two scenarios: one where there is interference of the gear and the bushing; and a second where there is not enough clearance or float. What it doesn’t consider is if there is too much clearance between the gear and the bushing. That is the case on my TR4 engine. I had 0.016 clearance and added a 0.010 shim under the gear to get the desired 0.006 clearance. Has anybody else had this experience? And what did you do about it.</div>
