<div dir="auto">Hey Bob,<div dir="auto"><br></div><div dir="auto">And happy Thanksgiving. When I was running Fletcher's old car I ran a diff cooler to help with failures. At the time it was set up with a belt on the right side stub axle and mechanical pump. If I did it today I would use an electric pump.</div><div dir="auto">I also burned through a couple rears before I properly matched my revs...too much pressure on the diff...using it to slow the car instead of my brakes.</div><div dir="auto">I think I turned some of my fastest times 1:25 at Summit Point but sacrificed a diff going down the shoot with poor rev matching. I may still have that pinion with no teeth left around somewhere to remind me.</div><div dir="auto">I really think a cooler would help longevity if you don't currently run one...and yes any form of LSD, especially a torsen/quafe creates a ton more heat to try to dissipate...even more fluid capacity is good.</div><div dir="auto"><br></div><div dir="auto">Cheers</div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Nov 21, 2018, 10:19 AM Jack Wheeler via Fot <<a href="mailto:fot@autox.team.net">fot@autox.team.net</a> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="m_-1364502047064798880ydpc7dbbde5yahoo-style-wrap" style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><div></div>

Looks like a couple of bolts backed out and when the shit hit the fan, the 4 or 5 that were still holding on sheared off. In any case, lots of metal bits in there. Some of the big pieces bounced around in the diff and there's some gouges in the Tran-X center section. The question to the group is - assuming that I find no cracks in the center section, it it accepted practice to clean off the dings to prevent stress risers and re-use it or is this a "tosser".</div><div class="m_-1364502047064798880ydpb94af08dyiv8313936560ydp243c3563yahoo-style-wrap" style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><br></div><div class="m_-1364502047064798880ydpb94af08dyiv8313936560ydp243c3563yahoo-style-wrap" style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px">Speaking of Tran-X, does anyone sell those now or are we limited to Quaife and GKN? I see that Rimmer lists both of those units. To be honest, I'm not a fan of Quaife because I have to run the rear a lot softer to prevent wheel spin in the tight stuff - that kills my times at places like Thompson and Palmer (like 1.5 to 2 seconds a lap.) Speaking of GKN, I know nothing about them other than "clutch type differential". Feel free to chime in if you have experience with those units.<br></div><div class="m_-1364502047064798880ydpb94af08dyiv8313936560ydp243c3563yahoo-style-wrap" style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><br></div><div class="m_-1364502047064798880ydpb94af08dyiv8313936560ydp243c3563yahoo-style-wrap" style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px">Also, I am nearly 100% certain that I was using new lock washers and Red Loctite high strength thread compound, so the bolts backing out was a total surprise when I cracked the case open. I was assuming that the pinion head had sheared off based on how the car felt when the diff broke. It was BANG and done - box full of neutrals.</div><div class="m_-1364502047064798880ydpb94af08dyiv8313936560ydp243c3563yahoo-style-wrap" style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><br></div><div class="m_-1364502047064798880ydpb94af08dyiv8313936560ydp243c3563yahoo-style-wrap" style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px">Off topic - looks like I'm not driving at ButtonWillow, I got a reply from Joe Siam that he has nothing available for that date.
