Viscous fan package?

famous bob said
I didnt use studs this time , I used a hair longer grade 8 bolt w/ a flat washer .
I cut the lip off of the back of my clutch ,about .100 , wish I`d have gone another .20 or .030, that lip doesnt do anything , and is just extra mat`rl.
I still had to install one bolt ,"leave ''unscrewed'' a bunch, to set the clutch groove in , to help get the fan in position, and rotated it around ,starting all the bolts w/ it way loose , and had to use needle nose pliers to get it in position ,( I WAS DOING IT W/ BURNED FINGERS ON MY RIGHT HAND). If u tighten one to far, u cant **** the thing out enough to get all of them started. w/o cutting the lip off , I doubt I could have done this ,then it would be back to using the studs , u can cut carburator studs to the exact length < trial and error .
Cutting the back of the clutch can be done easy in a lathe , my lathe took quite a bit of imagination because it wasnt big enought to swing the clutch over the cross slide , I would recommend having it cut by a machinist , would be ''no big deal.''
HANG IN THERE , ITS STILL A ***** !----LOL

Bob, I got it in, what an ordeal. I cut off some bolts like u suggested and used red locktite to hold them in the waterpump. I took the bolts out of the fan so it would tilt out of the way a little & give me a little more room. That made it a lot easier. I couldn’t get a lock washer on it, so I hope it it will stay tight. Looks like the slots in the clutch might dig in to the nuts and help.

I have a 7 blade fan. Looks like it would be easier with a 5 blade fan since they are asymmetrical and there are bigger spaces between some of the blades.

Having a bag of nuts helped cut down on the swear words, since I didn’t have to get under the car every time to look for a nut. I bet I dropped 30 or 40 of them.

I made a shroud out of a Ford Explorer shroud, and it is two piece, so I can install it last. That was very helpful as well. Don’t need anything else in the way to make it harder.

Machining of that ridge is a great idea, but out of my skill range. I wonder if Hayden ever actually installed one of these?

Thanks again for the help!
