Project LQ4 - V8 S10 - Sold.

Re: Project LQ4 - V8 S10 - Rear end stuff...

I tack welded the Explorer brake cable bracket to the frame. Should be just enough to hold permanently, or remove easily if needed.

Splash a little paint to make it look professional

This may or may not work, but for the 15 minutes it took to burn the bracket on to the frame, I'm willing to give it a shot. It's a zero dollar solution if it does work.

Coming back to the party pretty late. Couldn't you swap the gears from the new rear into the old and save the cutting/welding?

For sure. Certainly an option. Like I've seen you say many times before, anything is possible. I chose to modify a completely different rear end for a couple reasons;

To buy just the ring and pinion gear (even a used set) would be nearly half the cost of a complete junkyard rear
Installing a gear set requires tools I don't currently own (dial type inch lb torque wrench for the pinion pre-load), dial indicator with mag base...
I would also need an instal kit (crush sleeve and assorted shims to locate the carrier) There's about another $100. Give or take.
Probably the biggest reason is, I didn't want the hassle of setting up a new ring and pinion set. Backlash, tooth pattern, pre-load... Forget all that noise. Cut the tube twice, clamp on some angle iron and burn it in. It's a gamble, but it's a pretty safe gamble. Like hitting on 11.

Plus, I was able to sell (at full disclosure of it's condition) the 4:10 rear for $170. That's close to what I paid for the "new" 3:73 rear. I call that a wash.

Re: Project LQ4 - V8 S10 - Rear end stuff...

Well I did end up moving the bracket back a couple inches. Looks like bracket placement is what determines/balances the timing between the right and left brake. I tried to get it as close as possible, but the spring should compensate for any error. Clamped a vise grip to the cable and gave it a tug. Stopped both wheels from spinning while in the air. So far, so good...

Just need to figure out what to do with the extra length.

My options:
1.) Try to find a pre-made 26" intermediate parking brake cable
2.) Try to find someone locally to swage (?) a new end on the existing cable
3.) Put a loop in the existing cable and secure with a cable clamp to "use up" the slack

I'm leaning toward #3 just for proof of concept. If the cable gets damaged, I can get another section at the yard.

Re: Project LQ4 - V8 S10 - Rear end stuff...

id be all over #3 too, cut the cable in a clear area and use two cable clamps.

 

[BrandonHall10]

Re: Project LQ4 - V8 S10 - Rear end stuff...

Yup. That's what I did. Too much effort to cut the cable though. Just make a loop and call it.

The concept proves good. The brakes hold........mostly. Enough to keep it from moving while idling in gear, but nothing more than that. I'm betting once I adjust the pads, the hold will be greatly improved. I'll do that next time I have the wheels off.

Re: Project LQ4 - V8 S10 - Rear end stuff...

Up next will probably be the power steering pump rebuild. I'm like 99% sure my leak is from the seal between the pump and reservoir. Not sure you can get just that seal, but a complete rebuild kit is only $15. If you're going to take the time to pull the pump, might as well do a full rebuild.

And the part number

Seems to fit a ton of different GM vehicles. They put that Saginaw pump in a BUNCH of different vehicles. FWIW, Autozone had the best price I could find. (Top number)

Re: Project LQ4 - V8 S10 - Power steering pump woes

Bought a new tool. No more borrowing the clapped out loaner from the parts store. I had to find one with a pretty decent reach. The pulley that I use has to be pressed on way beyond the end of the shaft to get the belt to line up. Best $25 I've ever spent. Ebay is great for lightly used specialty tools.

Power steering pump is rebuilt.

Set it up for a bench test to insure it worked. Full disclosure... I had to do it twice. First time I didn't get the snap ring fully seated in it's groove and the back cover popped off as soon as I started bleeding the system. Hence the bench test. I don't want to do it a 3rd time. Anyhow, a hand drill proves it works. I'll let it sit overnight to make sure there's no drips from the case.

Not in a hurry to get it done. Won't be able to (easily) pull it out of the garage for a couple days anyway. Waiting on a part...

Re: Project LQ4 - V8 S10 - Power steering pump woes

work trailer has the same spring set up on the door, we had to replace the whole damn bar and both springs, but changing just one is not all that hard, only tricky part is the pre load on the spring.

 

[cheatah faheatah]

Re: Project LQ4 - V8 S10 - Power steering pump woes

Based on the dust, you know the preload is around 8 turns. The door guys that come to my work paint a stripe down the spring before preload.

 

[Scottydoggs]

Re: Project LQ4 - V8 S10 - Power steering pump woes

yup, 7-8 seems to be the magic number, this set we just installed had a painted line down both springs, made life easy.

Re: Project LQ4 - V8 S10 - Power steering pump woes

Something like 30-32 1/4 turns for a 7' door. I'll cross that bridge when I get there...

So the truck is back together. Pump seems to be working. No apparent leaks. Nothing major yet at least. Now that that is done, I can start on the next piece of low hanging fruit. Trans temps. After about 30 minutes of steady cruising, it'll get up to 220°. I'd prefer it to stay under 200° at all times. Considering I live in the desert and my driving style, that's going to be a tall order. However, I think I have a plan...

A tru-cool H7B 11"x11" 29,200 btu stacked plate oil cooler with a 1600 cfm fan.

Remember that hole I cut in the bed to access the fuel pump...? I'm thinking I can make that functional. There should be some airflow through when cruising, then when the fan kicks on, it will draw through from underneath.

All controlled with a 190° Derale fan switch relay kit.

Originally, I had planned on putting it entirely under the bed at an angle, but there's just not enough room for an 11" square cooler down there. This one's going to take some time. Got fab work, plumbing and wiring. Plus I gotta make it look good.

Re: Project LQ4 - V8 S10 - Overkill trans cooler build

^^^ Thanks guys. It's been a while. Small update;

Garage door is back together and working. Power steering pump is back on, and it appears the leak is fixed. Still poking away at the trans cooler. All the fabrication is done. Working on the wiring now.

And I had some fun the other day.

 

[BrandonHall10]

Re: Project LQ4 - V8 S10 - Side project...

Picked up my next project today.

It runs, but the wiring needs help. My bride wanted something to tool around on while the boys rode their quads. I need to find a small utility trailer.

Re: Project LQ4 - V8 S10 - Overkill trans cooler build

Just build a second story roof rack on the S-10, ala London bus or car carrier...lol. Looks like a fun machine. You'll have it pulling wheelies in no time.

Re: Project LQ4 - V8 S10 - Tuning for MOAR POWER!

So now that all the major mechanical kinks are ironed out, it was time to do come tuning. Finally... I'd been fighting driver issues with my other laptop for a long time. Eventually just said forget it and got a cheap 11" Inspiron from the Dell outlet. It has the bare minimum required to run HPT, but it works without any issues. Plus the battery lasts forever.

Started with the VE table. She was off just a little.

Got everything within 5%.

Probably drive it once, maybe two more times to get it even closer. Should be in the 70's tomorrow and I'm off work, so why not?

Pretty sure that would be more than that truck would want to haul. I pulled one leaf and the overload to get the rear down a little. Long term plan is to register and insure it so we can take it on the road.

Cool. :th_winking:

Thanks! My wife likes it, so I got that going for me.
