When I installed the rebuilt engine (with a flex fan for the first time) in my Tiger, it made contact (slight) steering rack under the fan. My fix was easy: I inserted 1/8" thick washers above both of my engine mounts (one at each mounting bolt). That raised the engine enough to miss the steering rack tube.</span></div><div id="yui_3_16_0_ym19_1_1508619583489_5887"><span><br></span></div><div id="yui_3_16_0_ym19_1_1508619583489_5887"><span>Bill </span></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1508619583489_5898"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1508619583489_6049" style="display: block;"> <div style="font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px;" id="yui_3_16_0_ym19_1_1508619583489_6048"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1508619583489_6047"> <div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6046"> <font size="2" face="Arial" id="yui_3_16_0_ym19_1_1508619583489_6050"> <hr size="1" id="yui_3_16_0_ym19_1_1508619583489_6152"> <b id="yui_3_16_0_ym19_1_1508619583489_6902"><span style="font-weight:bold;" id="yui_3_16_0_ym19_1_1508619583489_6901">From:</span></b> "tigers-request@autox.team.net" <tigers-request@autox.team.net><br> <b id="yui_3_16_0_ym19_1_1508619583489_6904"><span style="font-weight: bold;" id="yui_3_16_0_ym19_1_1508619583489_6903">To:</span></b> tigers@autox.team.net <br> <b><span style="font-weight: bold;">Sent:</span></b> Saturday, October 21, 2017 4:39 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Tigers Digest, Vol 9, Issue 281<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1508619583489_6054"><br><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6151">Send Tigers mailing list submissions to<br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6150"> <a ymailto="mailto:tigers@autox.team.net" href="mailto:tigers@autox.team.net" id="yui_3_16_0_ym19_1_1508619583489_8001">tigers@autox.team.net</a><br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6148"><br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6371">To subscribe or unsubscribe via the World Wide Web, visit<br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6053"> <a href="http://autox.team.net/mailman/listinfo/tigers" target="_blank" id="yui_3_16_0_ym19_1_1508619583489_8000">http://autox.team.net/mailman/listinfo/tigers</a><br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6370">or, via email, send a message with subject or body 'help' to<br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6055"> <a ymailto="mailto:tigers-request@autox.team.net" href="mailto:tigers-request@autox.team.net" id="yui_3_16_0_ym19_1_1508619583489_8003">tigers-request@autox.team.net</a><br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_8004"><br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_8005">You can reach the person managing the list at<br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6056"> <a ymailto="mailto:tigers-owner@autox.team.net" href="mailto:tigers-owner@autox.team.net" id="yui_3_16_0_ym19_1_1508619583489_8006">tigers-owner@autox.team.net</a><br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_8007"><br></div><div dir="ltr">When replying, please edit your Subject line so it is more specific<br></div><div dir="ltr" id="yui_3_16_0_ym19_1_1508619583489_6057">than "Re: Contents of Tigers digest..."<br></div>Today's Topics:<br><br> 1.

Another local tiger guy came by to put another set of eyes and ears on the problem. Sure enough, with the fan running, he detected some wobble/vibration in one of the blades. We removed the fan for a closer inspection. Sure enough one of the blades had a longitudinal crack in the aluminum blade running right along where it is riveted to the hub. The crack ran 3/4 of the way from the base of the blade to the end...probably getting close to total failure.</div><div id="yui_3_16_0_ym19_1_1508619583489_6126"><br></div><div>So now time for a new fan.

<br>
Thanks for all the input. This morning I removed the fan belt...and voila...the noise disappeared. Video with sound is below. I had a before video also but it made the email too large.<br>
<br>
<br>
<br><br>
<br>
<br>
I made a checklist of yesterday’s input and here are the results:<br>
<br>
Pulley hubs: All secure, no wobble<br>
Spin fan & gen: No odd sounds...no contact with anything.<br>
Dipstick: Straight<br>
Fan & individual blades: Secure<br>
<br>
Water level: Perfect<br>
Gas: Shell 93 octane...always.<br>
<br>
So what do you think. The fan is not hitting anywhere. With the fanbelt off the timing chain would continue to run...but no noise. I think those results rule our fan contact and stretched timing chain.<br>
<br>
That leaves me with failing water pump. Although I am still a bit concerned that I did not hear any noisy bearings when I spun the fan or listened at the pump cover with the stethoscope.<br>
<br>
Your thoughts/ideas please.<br>
<br>
Thanks<br>
<br>
Jim<br>
