Welcome, Sean. You didn't mention diesel or turbo, so I'm gonna just speculate that you have a 2.3 gas truck.

I wish they'd had a SpaceCab in '83, when I bought mine.

It's all back together, finally. If you've ever replaced a vacuum pump, you know that the hub slips around inside the casing, and its center hole does not stay aligned with the hole in the case, unless you hold it there somehow. And if you put it on while disassembled (backplate, then hub, then cove...

Seems the biggest issue is where the old shafts went through. I cut a DIN sized hole right through those. Then a plastic spacer plate mounted behind the new radio faceplate made it presentable.

Yep, she needs her own account!

Not lookin' so great for Gonzaga at the moment. Hope it improves.

I replaced with a champion 240z aluminum radiator ,cut a small corner off battery tray, and I stay 1/3 up the gauge. I am in st pete fl., large city stop and go traffic, hot , ac on and run cool, finally Somehow I missed that you're in St. Pete. My wife and I were in Dunedin just after Thanksgiving...

Welcome.

Welcome to the site. Yes, LUVTruck.com will be essential for your project. Traffic has slowed down there over the years, but they'll be happy to see a new member starting a restoration.

Brook, I'm not able to give you a detailed answer -- responding via iPhone just wears me out. :( And I'm really not familiar with how things work with an automatic transmission. But you said you don't have a schematic, and it sounds like you'd know what to do with one. There's one for an '83 model h...

I have a hunch about where this trouble began. Several years ago, my oil line (from the block to the vacuum pump) cracked. Although the engine never ran out of oil, I suspect the vacuum pump got starved pretty badly. So I imagine that's when the pump got really hard to turn, and damaged the shaft an...

I've pulled several from P'ups and Troopers at the salvage yards. Sometimes I'd struggle with one for 15 minutes, take quick rest, and then lift it off so easily I almost smash my face with it. I concluded that you have to sneak up on them! :lol: But seriously, I think some jarring (like with a rubb...

Ok, I can confirm, the alternator did NOT come with a vacuum pump http://www.isuzupup.com/viewtopic.php?f=34&t=19116&start=45#p124438 So this one was probably my original. If I recall correctly, the original alternator had stripped its shaft splines almost smooth, so the hub would have also ...

1,500 miles is a very short time for it to strip out like that in the absence of something being stuck or horrifically out of balance. Does the shaft have any wobble to it or possibly some lateral thrust that was causing it to saw in and out of the splines? You're losing me here. I had the engine o...

You must have had the belt pretty tight for it to strip the splines instead of having the belt just slip and burn. Were all the paddles inside the pump intact and how are the bearings on the alternator? I don't think the belt was unusually tight. I haven't touched it since I got the rebuild done by...

Good afternoon, We have a 1986 Isuzu Pub with space cab available. It belong to an Uncle who recently passed away. It is in Miami, Fl. Would like for an enthusiast to have it, rather than the junk yard. It has a fuel injection issue, but for the most part is in ok condition. Moon roof will need wor...
