I purchased this kit and had a heck of a time mounting it because the directions were terrible and the bolts won't fit through the slide channels where they say it should. Does this look right to anyone. The top bracket is opposite mounted of what directions show and the bracket that uses the mount from the old generator makes the nut barely fit the bolt after leaving the lock washer off. This kit came from this site. Any thoughts?

his kit came from tbis

As long as the pulleys are in line & the alternator can pivot to tighten the belt, then you should be OK.

PS
There is no need for a flat washer on the adjustment strap at the alternator end, the spring washer will bite into the strap itself & without the superfluous washer the bolt will be long enough to engage fully with the alternator threads.

You have to have an open mind and get creative when doing a changeover. The kits are a universal type, not a tried and true fit. In other words you can make it do what you need with minor changes.

From what I see the bottom bolt looks fine. Can't tell about the belt alignment from the pic. If the belt is true you are correct on the bottom. You need to take the top strap off. Pull back on the inside bracket to straighten it out. Then put the top strap back on the backside of the alternator boss so it will be straight. Won't hurt a thing to bolt from the rear.

If the belt alignment isn't true you need to shift the bottom to make it so. Then mount the top, inside or outside so it will be straight. If worse comes to worse you can put the top strap in the vice and make an offset in it so it will mount straight.

On the top of altenator does it still need the lock washer where it threads into mount ?

I question the alt pulley they sent ya I would confirm its correct for 5/8" belt if not down the road once the belt wares it will undercharge the battery. BTW that is a nice mount for the application I see no need for a flat washer unless its used where the slots are.

The alignment looks good, the belt could stand to be a little tighter, but not so tight it over stresses the water pump bearings.

The top bracket, the vertical one coming up from the water pump bolt... Kinda schety with only one bolt and the open ended slot. If it will lean on back against the pump housing, maybe it will be OK. I would just keep an eye on it, if it breaks then try a redesign, maybe eliminate it in place of a one piece adjustment arm with a curve, lower the alternator as far as possible by turning the lower bracket downward.

The bottom pivot bolt appears to be loose. It, and all other bolts must be tight, otherwise they will vibrate loose. The bottom pivot of the alternator needs to be tightly trapped tn the bracket, not just the bolt tight on the bracket. If you can get a thin washer in between the bracket and the pivot to tighten down on without stressing the tab on the bracket, all the better. Running it loose will eventually wallow the pivot hole and cause miss alignment.

Steve its a nice sturdy set up I have used it numerous times my hats off to the designer.. Its solid I guarantee....

Tighten up the belt tight confirm the pulley is correct for the belt life will be good...

I would add flip the upper strap end for end so the slot is at the alternator. Keep the thicker flat washer there to bridge the slot and us a longer bolt if needed to get full thread engagement in the aluminum. Put an insulating cap on the output lug. Looks fine otherwise.

Steve@Advance · Oct 21, 2019

Hobo, I see the top vertical bracket goes all the way down to the bottom bracket.

One picture looked like it was cut off below the bolt, but I see now where it goes.

Looks a lot better in your link.

As Steve said you need to work a flat washer into the lower bracket (paying attention to belt alignment) so you can tighten lower bolt down. Then I think top bracket that goes down to water pump needs to be hooked to water pump at top bolt (this bolt may be broken off in your pics) then slotted end hooked to alt either front or back side of tab. The short slotted piece will not be used. The way it is both alt mounts are close to each other, alt will do a lot of bouncing, hard to keep belt tight.

He's mounted to the water pump correct...
