Hayden 2765 clutch, fan won't bolt up? #1491119 08/26/13 11:40 AM 08/26/13 11:40 AM

It seems to bolt up fine to the WP but the bolt pattern is not the same where the actual fan bolts to the mounting pads on the clutch. Which fan do I need to get? The bolts on the original 5 blade are 3" and the 2765 is 3.25". I don't think elongating the holes would be a good idea due to balance issues. Sorry, no part # on the original fan that I can see. Thanks for the input. Pics below for reference. - Greg Fan '71 Duster '17 Ram 1500

The only discernible numbers on it are actually letters - H EOME D on the outside of the blade and what looks like 35 0E (maybe?) by where the blade is riveted to the center. It looks like the MP viscous fan but I'm not sure. Can anyone verify what the fan clutch bolt pattern is of a 5 blade fan? '71 Duster '17 Ram 1500

I did not install it myself, it came with the car. Regardless, can anyone tell me what fan blade I need to get to make this work? Or at least verify how far apart their blade-to-clutch bolts are so I can look for what I need? I can take it to a machine shop and have it accurately drilled but the $60-$100 that's going to cost seems like a waste if I can get the right blade. I did not think this was going to turn into a hassle. Silly me. '71 Duster '17 Ram 1500

Neither of these are easy to find by themselves and I'd rather not buy the MP viscous fan package just to get the blade. Thanks. '71 Duster '17 Ram 1500

Took them one day to get it in. FYI: The Hayden part number for an 18" clockwise rotation viscous fan is 3618. The 19" fan is 3619.

Just sayin' The Hayden 3618 is the one I asked Napa to get! Guess there's not much call for one of these fans anymore. Summit actually has it for $35. The Derale fan mentioned above is pretty similar but is smaller (17") and $10 more. I'm still checking around with some more local sources but no one seems to have it and if they can find it, its two weeks to get it. None of the salvage yards/recyclers around here seem to have anything much older than 10 years. I'll probably just order it from Summit and be done with it. What a PITA. '71 Duster '17 Ram 1500

It was an OE part from a small block Mirada. 5 blade, approx. 20" across. It bolts up to the Hayden 2765/Jag clutch no problem. I have 5/8" clearance between the face of the clutch and the rad. core. Next issue is figuring out how a 22" shroud is going to work with this fan but I'll figure something out. Thanks for the replies. Pics below. '71 Duster '17 Ram 1500

I purchased the same hayden fan clutch and there was no bushing and its very sloppy/loose on the water pump shaft. Common sense, the least common of all the senses. Mom.
