Technical Alternator Stuck

[Kalel]

my mechanic aka my friend from down the road has come stuck at removing the alternator. He says the big bolt that holds it on is seized. he now wants to take the engine out which I don't want to do.

Any ideas on getting this bolt to give? He has hammered it with no joy.

Cheers

Hi there... as you probably know, the head of the bolt fits into a hexagonal hole on the alternator. This is the long bolt that goes across the bottom of the alternator. The top bolt is shorter and bolts into a curved slot, for setting the belt tension.

My advice would be once you have the top bolt undone, take the nut off the lower bolt, then spray CRC 5.56, WD40, etc. at the bolt while you pry the alternator in and out as though you were setting the belt tension. Then put the nut back on the long bolt and hammer that, though access is tricky behind the engine and above the driveshaft.

Cheers Alex, I just can't afford to pull out the whole engine to get an alternator off. I'd rather smash it to bits and buy a new alternator

Looking good Kalel. It's a bummer working in tight spaces and when a bolt sheers it can bring a grown man to tears. The thought of a 1 hour job become a couple of days work.....

Thank you. The hardest bit to deal with is that I had to have the engine taken out...then temptation kicked in and I wanted to replace bits that were readily accessible...I managed to hold off with just changing the timing belt, tensioner pulley & fan belt.
