hi everyone, recently i traded a good runner srv for a 94 formula 583 blown motor, what i need is help, i have the ski-doo manual. but it is missing wiring diagrams. as well i would like a picture of a formula with the shroud open so i can put it back together. i know i am missing alot of parts and the salvage yard is my best friend. i have the motor apart and the crank at a machine shop, it is costing me $670 for a rebuild crank, all seals and gaskets, '20 over pistons with rings and new rods and bearings< i think i am getting a great deal>, any one know if i can put a starter motor on it?, does anyone have a wiring diagram? thanks in advance for your replies

I have a diagram, what do you need to know?

well i got this machine with the 583 out of it and a fan cooled 500 in it, the guy who i got it from had the harness out of it, and the gauges all have been snipped, i need to do some rewiring but i didn't take it apart to know how to put it bake together. kinda in the dark, been looking all over the internet and cant find one. a schematic would be really helpful. i guess i should really buy a shop manual.

also, when i go to rebuild the motor, i will need to get the rotary valve timed, there are two scribe marks, but i will need a dial indicator, is this to make sure i have top dead center?

another question, i never got the air box with this mess, can i use 2 air filters on the carbs? k&n perhaps. is there any sensors in the air box, or is it just to clean the air?, will have adjusting problems, back pressure?

Find an airbox on eBay if you can, that way there will be no problems with carb icing, etc. Get a Clymer's manual for it too. That's the manual I have, it has wiring diagrams in the back. There is a method for timing the rotary valve, I can post it if you want, but that Clymer manual is your bible for that sled.

well this is what i am into, just got all my parts back from the machine shop, costs a little more than i was quoted, well now the snow is almost gone, cant wait for next year. anyone with helpful tips would be helpful. thanks snowmobile forum

well, i have the engine back together, timed and primed. the problem i am having now is the recoil wont recoil with the flywheel on it, i took it off and it works fine, is this ok?

**smallengineguy** · 04-02-2008, 06:07 PM

Something is binding. Is the spring that wraps around the hub bent?

danno583 · 04-02-2008, 06:12 PM

the recoil is rubbing on the lips of the hub i will post a pic in a few minutes, thankh seg

danno583 · 04-02-2008, 09:41 PM

i was looking at it and the starter pully is rubbing up against the pawl on the recoil. the only way for it not to rub is a spacer between block and the recoil. i dont have a spacer do you think i can use washers. i guess the flywheel is important. thanks again for your help. i am also using the ski doo shop manual 1994.

danno583 · 04-12-2008, 03:13 AM

i have gotten all the wiring figured out and the motor installed. wondering why there is two fuel shut off valves? and there is two pulse lines off the motor? and aswell i have a seal left over, but there wasn't any room on crank. thanks for the reply s. has anyone used spx pistons?

danno583 · 04-12-2008, 03:24 AM

my friend gave me and my daughter that 2up seat, nice guy. thanks

**smallengineguy** · 04-12-2008, 07:52 AM

All the sleds of those years had 2 fuel pumps, 2 shutoffs, etc.

When you get done, you will have to really wash the motor and engine bay down

Jim Jessup · 04-12-2008, 04:48 PM

SPX pistons are fine.

everytime i go to the hardware store i forget to get a can of engine degreaser

danno583 · 04-14-2008, 10:51 PM

well i got it started today, recoil issue was the start pully, it was the wrong part. the new issue is does anyone know about mikuni carb jetting. i have 440 in both, i live in southern ontario. i was told that they would be too rich. thanks for all your replys

**smallengineguy** · 04-15-2008, 07:06 AM

OnlineMicrofiche Index Look up your year, model, etc. Then click on carbs. That will tell you what the jetting is for the mains/pilots.
