Well I'm almost finally done installing my new alt. USPS/Canada Post decided to make me wait months after it was dropped and broken in shipping. Long story short international insurance FTL, Mechmans FTW. Last week I received a non broken alt and went to install it. It didn't quite just bolt in like I thought it might. Understanding that the new alt is physically larger and might take some mods I had to make it work. (strapped saz1500ds @ 1 each, 100.2, couple 1/0 runs, 2 red top 34's)
Stock alt charging voltage at idle with no real load.
Played a test tone and voltage at idle dropped down.
Old alt vs. new alt. CS130 old, CS144 mechman.
This little area on the new alt was hitting the old rear support bracket. I didn't really want to cut the old bracket off in case I ever need to go back to stock alt. Removing the bracket can't be done without removing the PS pump. What I did was grind it off instead. Not recommended and would be better removed before the alt is assembled.
Now that it sorta fits I was only able to get 1 bolt in out of the 2. As you can see below the holes don't quite line up. Mechman said that normally that there is enough wiggle room to get the bolt in. I tried but it just wasn't gonna happen. So I opened up the hole a little so the bolt would fit.
Grinded open just enough via dremel and 2 minutes of time.
The ear on the new alt is longer so you need a new bolt. I also made a brass sleeve to take out any extra slop/slack between the case and bolt. Used an M8x70mm bolt, washers and nut. The old bolt threaded into the old alt case.
Now it's in and bolted in nice and tight. Here you can see the rear bracket which I chose to leave and just bent it back slightly. Obviously not enough as it still touches the case. I'm just leaving it for now. Had I not grinded the case there is no way it would fit here. You would definitely need to remove the old bracket.
