Sorry, guess I can't attach more than 5 files. I have plenty more pics and video. Just let me know and I'll send them

Well, the time has come to let go of my beloved 80. I have short/long term plans and need some $ to get started. 80 is a 1993 rhd with 1hdt that has been flawless except for alternator and starter, both of which are still oem, just rebuilt. I wouldn't hesitate to take her cross country and...

Interested in some info for the 1hdt

Can anyone give any insight as to correct adjustment of the tps? I'm in a hotel right now over a thousand miles from home with my wife and kids because my 93 1hdt with a442f is shifting all over the place. Replaced all solenoids about 7 months ago

Reviving this thread as I'm over a thousand miles from home with the family on vacation and mine is doing this bad. We are in a hotel room as I type because I didn't want to continue. Was it the TPS?

So, this is what lowered my boost readings ya think?

So I've recently fiddled with the fueling on my 1hdt. Power is better, little puff of black smoke on startup and under load. Egt's are still good. Followed LCOOL mod by turning star wheel in injection pump three clicks, top screw half turn in, and main fuel screw in approx a quarter turn...

Correct. That's what I'm worried about. Solenoid #3 (1 and 2 are the same) is also a one bolt bracket. They all are. 3 and 4 share the same bolt but only one, not two bolts

So the isuzu timing solenoid is a 2 hole bracket but not the oem one. It's just a1 hole. Does it fit okay?

I figured it out. On the 1hdt the ac pulley on the crankcase is the #2 pulley and is a single groove. The main crankcase pulley that runs the 2 belts for the alt and water pump is the 13408-17010 part number. The one I need is the 13407-17010 part number. Got it ordered last night! Thanks guys

So I'm going to need to do this asap. Was wondering if the correct AC crankshaft pulley has two grooves for two belts or just the one for AC.That part number (13408-17010) pulls up a pulley with 2 grooves on Ebay but it appears the one Tweeek used in pics is a 6 bolt single grooved pulley. Or...
