Alternative 24V DC Charging System Installation

1800,

You want to keep the unit as original as possible.

Let me suggest a different approach, if you have a tap set. I noted in your pictures of trying to pull the fan that you have a puller identical to the one I used to use on the fan. NAPA sells a straight bar heavy unit for about $25 that works much better for me.

My recommendation would be go back to the fan, get a better puller and try again with 5/16" bolts. If you pull the threads out, drill and tap for 3/8" or 7/16" bolts. I've had to do that twice and use a hammer on the fan base, to boot. If I recall correctly, I had to use the 7/16 drill to relieve the puller a bit to allow free movement, or perhaps I used 1/2 to relieve it's slot.

The puller you are using tends to pull at an angle IMO and I don't use it anymore. Given that it is a keyed shaft, any angle off true makes it impossible to pull the fan.

Good idea on the puller...I was thinking about going after a stronger tool. Will check out the NAPA unit. I noticed when I was pulling I really had to watch the orientation of the 5/16" bolts as they would start "leaning" to either side or up/down and the puller rod wouldn't be level.

I assume yours looks like a steering wheel puller, just heavier/thicker? Also thinking instead of letting one of the 5/16" bolts break during the next attempt, why not go ahead & drill out the holes for a 3/8" tap? That way I know the holes are at the same center...also I have a few sets of GR8 3/8" bolts too...

The Napa puller is a rectangular bar about 5-6" long and about 3/4" x 1". Real simple and strong. No provision for a third pulling point, like the one you are using.

BTW: Use hardened bolts. My SS ones would bend like butter.

Already got that covered. Paid a visit to my local bolt wholesaler the other day & picked up an assortment of GR8 bolts from 1/4" to 3/8"...good-to-go there...
