i'm putting together a 350 to put in my cj7. i picked up this rebuilt tbi motor from a guy who bought it from a local engine shop but never used it. it came like this... (i've got the tbi stuff also)

http://i32.photobucket.com/albums/d22/dt5150/DCP_0545.jpg

as i understand it, there are 2 different belt/accessory setups that i can do, right? one being a serpentine and the other a v-belt setup? is that correct?

is it currently setup for a serp? (minus the accessories of course) that fan and lower pulley stick out pretty far.

which one would provide a self adjusting belt, the v-belt configuration? i'd also prefer to have the alternator on the pass. side. and i think i need a short water pump too.. and would that be reverse flow?

i think it's got a fan clutch on it, does it look like it? if not, should i put one on?

this is the first time i've dealt with a chevy motor so i'm as green as one can be, but i'm trying to learn. any help? thanks...

anyone?

looks to be the v-belt power steering -ac. setup. uses a serp style belt for the alternator. v-belt under the alternator for the smog pump. the short style pumps were for the above setup and v belt drives.

thanks odee. fortunately for me, i don't need to pass a smog test so i just need the essentials so to speak. power steering, alternator... i just don't know what i need for bracketry.

88 and up *(I think, dont quote me) used an aluminum bracket that bolted on the front of the motor for the accessories. power steering on left lower *(driver side) alternator on upper right, reverse flow water pump, with a couple of idlers, (one to remove the smog pump, the other to take up where the A/C was) would work.

or, 84-86 trucks used a standard rotation water pump, serp type pulley for the fan/alt/crank, and a separate v-belt for crank/fan/power steering.

Vans are all different than this... boy what a mess they were... van brackets could be fun to work with... just mounts too much too high, though.

thanks grumpy. by the looks of it, i think mine is set up for the standard rotation water pump, serp pulley, and v-belt config. i was told to run a short, reverse flow water pump, with the rest of the stuff to eliminate the smog and a/c. the first config you described. can or does that run a mechanical fan? would i have room to run one? i've been looking at summit racing for the parts but there are so many i honestly don't know what's what. some part #s would really help a lot if you happen to know any. i wonder if the guys at napa could tell me what parts i'm looking for...or even a picture i could bring with me would help.

Here is the best picture I can find of my 90 with the alum bracket. Its Serp setup with a clutch fan.

thanks. does yours have a/c and the smog pump?

doesn't one of these setups use and "auto-adjust" or "auto-tension" type belt?

found these pics.. is this what you're referring to?

You need the alum brackets that grumpy was talking about if you want the serpentine belt(self adjusting with tensioner). They are two piece, one on d side with alt and ps pump and the p side holds the ac and smog. My jeep uses this style and I have a delete bracket for the ac and an idler pulley for the smog since mine was a tx motor.

Some of the earlier tbi 87-91 on the square body trucks used a serpentine/ v belt pulley system together also.

You can buy the alum brackets from pace perf, or summit but they are way $$$$.

Look on CL for them or a complete motor with them, I find them all the time for $100-150 on there.

If you don't want the mech fan, take it off and just use an elec. fan, that's what I did.

If you want part numbers look on advanced auto parts web site and its pretty good about letting you search for parts for different vehicles and usually has decent pics of the parts. If not let me know what part you are looking for and I can probably find it in my reciepts file from oreilly's for ya.

Sorry for the long winded post, but I hope it helped some.

yes very helpful, thanks mud.

from your description, the pics above are not of the self-adjusting with tensioner setup correct?

i don't need a/c or smog either so it sounds like yours is set up the way i want mine to be, right? or would i need my alt. on the upper right? you wouldn't have a pic by chance would ya?

Yeah I was actually at the jy earlier and took some pics on my phone just in case you asked.

You can see where the ac pump goes here and right next to it is where the tensioner pulley goes, on bottom would be where the smog pump goes if you have one.

Here's another pass side bracket but a non smog with a spot for a pulley where the smog pump would go. You can see the tensioner on this one.

You can see that they use a mech fan with a clutch but they can be removed without problem and you will have room for an electric fan if you choose to use one. Also depends on motor placement in the jeep.

Hope this helps and clears up some of the confusion, All of the brackets in the pictures use a single self tensioning serpentine belt.

Here is what mud is talking about. I would check CL like he said. Go under auto parts an search parting out.

that's fantastic guys, many thanks. that clears things up a ton.

so the driver's side is always the same, ps pump and alt., right?

but there are 2 different pass. side brackets, one with a spot for smog and one without? (is it hard to find one w/out the smog, and could i run either one?)

and if you're not running the smog or ac you put pulleys in their place, correct?

sorry for all the ?'s...

Yeah im pretty sure all the d side bracket are the same. Some differences in van, truck, etc, etc, but pretty much the same.

None of these brackets are hard to find, like I said I went to the jy this morning and saw more than I could carry out if I wanted to.

They sell eliminator brackets for the ac and Im pretty sure for the smog pump, but it is just as easy to find a non smog bracket and use that if thats the way you want to go.

If you can't find any where you are, let me know I can get some from the jy, not sure how much they would charge for them though. But I bet you can find them at your local jy as the tbi motors are very plentiful.

great, thanks mud. i've got a couple u-pull it yards around so i should be able to locate some. thanks again for all your help. much appreciated..

are the non smog on any specific years or models?

I don't know which years for certain. I have a 93 chevy that's non smog and the 89 sub motor that is in my cj7 has the smog pump provision but it's not used.

I would just look around at the pick and pull and you'll find what you want. Unless you are in Cali and then they are probably all smog motors.

Yeah I would look for a years of 88-95 5.7,5.0 and 4.3 Some of the s10 with the 4.3 non vortec had the same brackets also. The smog pump location isnt a big deal to work around. Just get a different belt of a truck that doesnt have it.

great, thanks guys. so i'll need a short, reverse flow water pump too right? any special alt. recommended? High output or something? i plan on adding a winch later on as well. i can re-use my cj stock ps pump i believe...

for the bracketry, i'll head to the jy as soon as we get a day that isn't raining!

Im not sure if it's a reverse flow water pump or not, I just ask the guy at the parts store for a water pump for a 88-95 chevy water pump.

Looking at the serp belt above, yeah I guess it is a reverse flow pump.

ok, thanks. i've got some shoppin to do.

can you tell from the pic of my motor if i need to change out that bottom pulley to another one to work with the serp. setup?

ok, thanks. i've got some shoppin to do.

It may work but im not sure. Got any other pictures?

i can take some more if it'll help..

but looking at it from this view, if i got a short water pump, the crank pulley wouldn't line up with the short pump.

i'll try to get a better one.


how do you get those pulleys off? do you need a special puller?

here's how how far the crank pulley stick out. too far for a short water pump setup?
