Default air pump eliminator dimensions

I am going to try and fabricate my own air pump eliminator and would like to know what the measurements of each straight bar piece is on this design bracket.

So if anyone has this style bracket can you please tell me the lengths of each straight bar so I can start with a good basis. Thanks!

I don't have that bar style, but you may find the measurements from mine will help with some of those dimensions.

The bottom larger plate is 7.5 X 1.5 X .500 thick.
Starting at the bottom there is a .380 hole centerline and .625 from the end. next is another .380 hole 2.00 from the first hole. On the other end is another .380 hole centered and .500 from the end. From that same end is the pulley hole, it is .510 centered and 1.625 from the end.

The thin bar is 9.700 X .750 X .375 X thick.
The end that attaches to the plate near the pulley has a .380 hole centered and .375 from the end. that end hof the bar has a full radius on it. The other end has a .380 hole .500 from the end but not centered. It is .125 from center and closer to edge closest to the alt. On the bottom side there is a relief for the alt. It starts at .900 from the end, arcs in about .187 deep and arcs back out at 3.625 from the end.

Where the two bolt together and pivot, there is a .375 thick spacer.

Hope that helps.


Jeff

who's got the best deal on these things if you're too spastic to make one yourself?

IBVETN2 here's your answere to where the pulley hole is. as for the spacers I'll bet it's safe to say they are the same size as the spacers in AGENT86'S template plans. Even though it's a different style bracket i believe they are spaced the same as long as the thickness of the brackets are both the same, if not you can calculate it from the differnece in the thickness...http://members.shaw.ca/dankai/Air%20...Delete%20Info/

IBVETN2

the thickness of the plate in agents plans is 3/8" in this one were're dealing with 1/2" unless you decide to make it 3/8" too. If not, the spacers should be 1/8" shorter than the ones in agents plans.

It is a .510 hole centered @ 1.625 from the pivot end.

I'll have to dig through some old notes out in the garage to get the spacer lengths.

Would this bracket be strong enough if made entirely of aluminum? How about made of aluminum and 3/8 in. thick instead of 1/2 in.?

Also, does this setup allow the use of the stock serp belt? And what size roller is being used?

Agent's plan is all one piece, the other one is two pieces with a .375 spacer between them. The piece going to the alternator (which is .375 in. thick) is going to be in the same plane regardless, so the two spacers holding the bottom piece to the head will need to be .375 in. (3/8 in.) plus 3/8 in. longer, or 3/4 in., and use a roller that sticks out 3/4 in. less, or 7/8 in. less if using 1/2 in. thickness stock. If I am missing simething here, please let me know, I was barely able to keep this all straight in my head, may have made a mistake.

Is yours the Agent 86 design or the other one?
