Application is SM465/NP205 backed behind an 88 350TBI motor. I'm debating on whether to go push slave or pull slave for my hydralic clutch setup. The bellhousing I have is from a 74, which did not come factory with a hydraulic clutch. The TBI motor also doesn't have many threaded holes in ideal places to mount a pusher (plus I have the oil pressure switch down there in the way). I'm kinda leaning towards a puller type, mounted directly to the SM465. Anyone have an plus's/minus's to add to either application? Does one style benefit more than the other? Can anyone share pictures of their application, specifically a pull type mounted directly to the SM465? I've got a couple pics of the push type already.

Thanks,
Chris

Here you go. I want to redo the mount, but it seems to be holding up so far:

I'm using a push type on my SM420 and Buick 231 bellhousing and it works fine. I think a lot has to do with where you can mount the slave cylinder. I built a bracket on to the side cover on the transmission to hold the slave.

Your OP switch is down there? It should be on the top of the motor next to the distributor. :confused: I guess it doesn't matter...

Bryan

yea, i'll take a pic of it tonight to show u.

Ok here are two pics I took tonight, one of what I thought was the oil pressure switch, which is above the oil filter, and the other which was right next to the distributor.

Which is the oil pressure switch and what is the other one?

Here's (http://mail.nicorenergy.com/ctatar/images/P8270202.jpg) the one above the oil filter.

Here's (http://mail.nicorenergy.com/ctatar/images/P8270203.jpg) the one next to the oil filter.

use the one next to the distributor, plug the lower one. The lower one was a low oil pressure sender used in late model GM's, when the o/p dropped it shut down the fuel pump. may be able to use if your gonna use electric pump..otherwise ditch it..use the other one with a mechanical guage.
As far as slave, I had fabbed my own that bolted to the two lower holes and used a pusher type that was a GM factory unit.
If your interested I just happen to have a factory bell housing with slave mounted to factory location...e-mail if interested

They both look like OP switches, but thats a TBI, so I bet that one is the OP cutout switch, and the other the OP sender.

What I did, was removed the factory brass fitting and made a small manifold (using stock brass fittings from the HW store) that the factory cutout switch went into, AND the line for my mechanical OP guage. This was all up near the distributor.

If you can determine that the unit near the filter is a sender for an electrical gauge, I'd rip it right out and plug it... then use a mechanical off the top near the distributor. Then you could go push or pull.

Make sure to consider manifold or header clearance before deciding to push....

I have the wiring harness and schematics, but haven't had a chance to start wiring up this pig. I am hoping OXJockey has some information and will wait to see what he has to say. Otherwise I'll just have to wait until I start wiring it up. As far as clearances, I plan on running the stock exhaust manifolds, so using a pusher may be out of the question. I like the puller setup shown in the picture above, and may end up going that route.

I did what Jim did, my OP switch is up top near the FW, and Teed off of that for the mech sender. My stock 1988 TBI motor did not have a sender near the filter like that at all.

I'm using stock manifolds, and the pusher fits fine, but I know you're bent on using a puller. :D If I get it back together this weekend, I'll try and snap some pics.

I found this in 4Wheel & Off-Road on one of their projects:

I may do something like this, it looks easy and cheap. I got the Parts Mike bracket, but the thing is all screwed up, the slave surface is not straight, I had to modify the hole to accept the bolt, grind my bell housing, etc.

I may call AA and pony up for theirs, but at this point the tranny is out again, so I have more room to work. I can use the PM bracket as a template for the slave mounting holes, at least. :mad:

Edit: Is anyone besides Jaffer using a return spring?

Bryan

Well, let me know what you end up doing, and pics always help matters. I've decided to put my clutch efforts off for a bit. Gonna concentrate on some other things and then electrical issues (graft two harnesses together, etc).

How do you know Jaffer is using a return spring? Seen a pic of his setup?

Dude, that's way too clean of a setup!! I like it, but way too pretty for me. You could eat off dat firewall!

Chris

The lower oil switch is for a gauge.The upper is for the computer,or if it is 3wire it is for both.The AA clutch brachet and cyl. did not give enough travel to disengage the clutch,on my 58 cj5 with a sm465 trans. I went with a86 chevy truck bellhousing and cyl. ,push type.

Thanks for the pic rkcrawl, I'm in the middle of the same thing and that looks pretty simple compared to some of the stuff I was thinking about :)

No problem. It works, but I want to redo it sometime over the winter. It flexs a little because there isn't a 3rd attachment point, aside from that I am pretty happy with it. My BH was actually setup for a push type, but I don't have the clearance for it with the shorty headers I am running. If you do it this way there is a location pin for the tranny cover that you have to drive out so you can get 2 bolts in there. Another way to do it is build the mount to bolt to the PTO access...

Yeah, I've seen it both ways, I did a search (good newbie :-), and saw the PTO cover mount on an SM420 which is what I have, but your bracket looks a little easier to do. I ordered the slave today from a local stockcar shop.

You don't have or need a return spring with this setup?

Hi Dave, welcome to PirateBB. :flipoff2: (I remember you from Jeep-L)

Anyway, I'm trying to muster information on this myself, stock applicatons have a small spring in the bellhousing, but after market has one externally? Learned today that AA sells their spring (AA PN716335) for $3.42, and it's hooked on one end, bend it yourself on the other so you can adjust the length appropriately. Jaffer gives his 1/16" clearance, with 'slight rattle'. I think I'm going to try the AA bracket (AA PN716287) with the TLC slave (AA PN716119) and see what happens.

I don't have a return spring slave seems to push out to max when I let off the clutch fine. I will check this out after this weekends ERoCC comp. Its not a daily driver, so I haven't put lots of miles on it since making this mount. A return spring wouldn't hurt a thing though :D

Hi Dave, welcome to PirateBB. (I remember you from Jeep-L)

Thanks Bryan! Yeah, I've been around a bit, this board's a little different then the L :)

On my past setup I ended up using various screen door springs to get the tension right for the return (YJ master, S-10 slave and bellhousing bits). Actually took quite a while, and a couple of throwout bearings, as an experianced mechanic told me with the hydraulic system the throwout bearing would always ride against the clutch. Yeah right! :flipoff2: I wondered why I went through them so quickly.
