Fan clutch tool help:

[E34 530]

Hey guys, I started my new job a few days ago as an assembler for industrial size pumps and decided to make my own fan clutch removal tool at my neighbor's shops. I just need to know what size the 4 bolts are on the water pump pulley. I would look myself, but my car is at my friends house because we've gone surfing for the last 3 days. Thanks again, Andrew

I drilled holes with a 5/16ths drill bit and then had to ream them out a fair bit with my die grinder. That's just the biggest bit I had handy. I think the holes need to be a little over 3/8ths of an inch, since it's a 10mm head on the bolt.

I used a pair of channel locks...worked perfect

Copy cat... hehehe. Actually, all you need is one hole and the other side brace against the bolt.

Fits everything from water pumps to harmonic balancers

i took out 2 of the 10mm bolts then used 2 pairs of waterpump pliers against each other , or if you have one , a 32mm spanner for the viscous fan

Hmmh,

no evolution of fan clutch tools?

I am sorry to revive an old thread, but can anyone tell me the OD of shaft that the tool has the clear that is in the middle of the pulley in between the two 10 mm bolts and the spacings in between the 2 bolts and the shaft.
I am going to fab one up before i goto holidays
