Question would it be safe to trim my alternator pulley blades down? fiesta rst!

hi guys, just fitted a new radiator to my fiesta rs turbo! just been thinking my alternator in the past has cut through my bottom radiator hose. the reason why the alternator sits this close is becuase i have my oil return welded into the sump for the T2 turbo.

would be ok just to trim my blades down around 1cm so it doesnt destroy my hose??

if you do anything like that you may cause cooling issues of the alternator. can't you fix the hose in a better position?

i was thinking about the cooling issues but there will still be some of the blade left to aid with the cooling. just thinking im sure some mondeos and my focus does not have these blades!

ive got a spare few pulleys i think so will give it a trial!

all done, fitted back onto the car and it still cools the alternator fine, plenty of cold air coming from the blades still

Your other alternators will have some sort of cooling fan but it might be inside the casing. Big manufacturers aren't in the habit of making things bigger than they need to unless it makes the manufacturing process cheaper - if they can save half a penny on materials on each alternator they will. You also need to consider that the assembly will be balanced (OK quite roughly compared to things like engine internals). Can you balance it again after chopping lumps off?

Personally I'd look at making a shield of some sort to protect the hose. Lump of metal, a bit of tin bashing and a bolt should see you right.

I wouldn't have thought the balancing issue would be too much of a problem as the belt pulls very tight on the pulley.

I would have gone for making up a shield option though!

mine was very close on my escort after moving the rad back, I put a few wide jubille clips around the hose where it would strike if something gave, this way if it does happen to come in contact for whatever reason, first of all you'll hear it and 2nd you can sort it out and if need be put some new jubilees around. Clips are a lot cheaper than hoses.

I trimmed mine down years ago, no issues at all. Also have a piece of steel wrapped round my hose.

The fins are like that for a reason...

Can you not move it or re route the hose slightly?
