MrLiken Posted September 20, 2015 Share Posted September 20, 2015 My fan hub suffered a catastrophic failure yesterday on the way back home. Does anyone have thoughts of what happened? I contacted Brassworks here in CA and told there is a 10 week turnaround. So much for the rest of the touring/show season.. I will take it to a local rad repair shop to see if they can solder/seal the core to get me through October. Link to comment Share on other sites More sharing options...
nearchoclatetown Posted September 20, 2015 Share Posted September 20, 2015 John, that sucks. Sorry to see that happen. What type of belt did you have on? It SHOULD be leather, but rubber can be used. The belt should be loose enough that the fan can just be turned when engine is not running. It may have been too tight at some point and cracked the hub. If you look at the break is there part of it that is rusted? doug Link to comment Share on other sites More sharing options...
MrLiken Posted September 21, 2015 Author Share Posted September 21, 2015 Doug,I have used leather in the past, but just recently changed to rubber. I may have had it a tad too tight. There was no rust on the break. So, you mean loose enough so that the fan will "slip" when the engine is off? Link to comment Share on other sites More sharing options...
cahartley Posted September 21, 2015 Share Posted September 21, 2015 (edited) To answer your question, yes.You should be able to turn the fan blade with one finger without a lot of effort.Any tighter is not necessary.And now that you posted this that reminds me I need to re-bush the fan hub on my '25.......

Guest DodgeKCL Posted September 21, 2015 Share Posted September 21, 2015 The core has pretty well had it so I don't think you can do any more harm if you take a set of very long nosed needle nose pliers and pinch off the damaged tubes from the back and front. Then put in some BARR's LEAKS or the equivalent. It may weep a bit but it should keep you on the road for the season. We used to do this and live with it when we had no money so it does work.

JayG Posted September 21, 2015 Share Posted September 21, 2015 That hub looks like it has been welded at some time in its' life. Link to comment Share on other sites More sharing options...
Taylormade Posted September 21, 2015 Share Posted September 21, 2015 I agree, I think the weld let go. Link to comment Share on other sites More sharing options...
Ian_Greenlaw Posted September 21, 2015 Share Posted September 21, 2015 Works now.......thanks Link to comment Share on other sites More sharing options...
nearchoclatetown Posted September 21, 2015 Share Posted September 21, 2015 I couldn't expand the pictures either. I see now that someone tig welded the casting in the past like others have said. Costly mistake. Link to comment Share on other sites More sharing options...
MikeC5 Posted September 23, 2015 Share Posted September 23, 2015 Ouch that hurts! It does appear to have been welded.... Someone trying to fix a crack perhaps. Poor judgement since getting a good replacement would not have been that hard to find. If the damage is confined to the aft row of tubes maybe it can be repaired.

MrLiken Posted September 23, 2015 Author Share Posted September 23, 2015 Thanks all. It was a weld with old and new damage. Apparently, I tightened the new rubber belt too tight. I had it so that it would not slip. I have the radiator at a shop now and he is going to blank off about 8 tubes on the rear. He doesn't think it will effect the cooling at all. I just need it to make it through the season with shows almost every weekend now, then will do a proper re-core.My next question has to do with the fan. The hub is getting repaired having new bushings inserted because it was pretty sloppy. As most here know, the cars' output is approx 35 hp. How critical is it to have the fan/blades true and who does that work if in fact it is critical? My radiator shop seems to think it would be, but has no idea who to do the work. I am searching for a replacement fan, but I'm sure there are no NOS fans out there, so anything I get will most likely need to be balanced. As always, your thoughts are greatly appreciated.

MikeC5 Posted September 23, 2015 Share Posted September 23, 2015 If it were me, I would not attempt to have that fan repaired. Have you tried contacting Myers or Romar to see if they have a good used fan and support rod? Link to comment Share on other sites More sharing options...
