Yes.
2.6 also has bigger valves unless the 2.3 is the Impulse version.

Re: Engine decoding question

2.6 engine designator is 4ZE1, 4ZD1 is a 2.3
'91 Troopers only came with the 2.6 4cyl or 2.8 GM 6cyl engines, both fuel injected. If the engine in question is the stock engine it's a 2.6, if it has "4ZD1" cast into the block it's a 2.3 & not stock to a '91 Trooper.

Re: Distributor question

I see from your intro post your truck has a 2.3 engine. The simplest way to transplant a 2.6 is to use the 2.3 intake & carb, distributor and flywheel. You'll also need a 2.6 water pump pulley so the drive belts will align properly- 2.3 & 2.6 pulleys have a different offset because the water...

Re: Distributor question

Only if you are using a carb. Or if the '89 is a 2.3/carb truck. The 2.6 distributor is computer controlled & synched to the EFI system & won't work with a carburetor. If the '89 truck is a 2.3/carb truck it doesn't have the computer or wiring to use the EFI distributor.

Re: Differential Identification

That's the correct part number for the pinion seal. You do know the caution about overtightening the pinion nut when changing the seal, right? Isuzu didn't start pickup assembly in the US until about 1991, rear end parts after that date are usually divided by Isuzu/GM or Japan/US-built. No real reas...

Re: Differential Identification

If your truck is Japan-built you have the Isuzu corporate 10-bolt differential. The "10-bolt" designation refers to the number of ring gear attaching bolts, not the number attaching the drop out third member to the axle housing. Ring gear diameter should be 194mm or 7.64", which is no...

Re: Raspy Scratching Noise Periodically on Acceleration

From what I remember(it's been a while) the drain & fill plugs have copper washers that are reusable, I've never had to replace one. The drain plugs are magnetic so don't swap positions, but I think the washers can be swapped if one is in better shape than another. The drain plug is more likely ...

Re: Raspy Scratching Noise Periodically on Acceleration

I just hope the diff even has oil in it! :shock: :mrgreen: It took about a pint, but wasn't too low to begin with! :D Transmission didn't need any motor oil added. A pint low is more than normal since capacity is slightly more than 3 pints. I think the change interval is 30,000 miles. With the rear...

Re: Raspy Scratching Noise Periodically on Acceleration

Quote: "Since I didn't have the torque specifications, I didn't mention tightening the nut to him and left it alone." There are no torque specs for tightening the pinion nut on a fully assembled unit. Any torque specs you can find are for initially installing only the pinion into a bare ho...

Re: Engine cranks, no spark.

Yes, the distributor is brand new, Cardone re manufactured. As well as cap, rotor, coil, plugs and plug wires. By mechanic buddy has been giving me advice, just like you. He lives in Tennessee though.I checked the two wires coming from the distributor with a test light. Both times that my daughter ...

Re: If it ain't one thing it's another.

Pull the rubber splash shield from the passenger inner fender liner to access the fuel pump through the fender opening. You can at least partially see what you are doing rather than doing it by feel from under the hood. You will need two gaskets, most fuel pumps only come with one. There is a spacer...

Re: Transmission job.

The only source I could find says 3.2 pints capacity, best way to be sure of the required amount is to remove the fill plug on the tranny side (15/16" wrench I think), add oil until it starts to run out the fill hole, whether you pour it in the top or into the fill hole.

Re: Transmission installation

Adjust it at the firewall. FSM says to leave a certain gap, shade tree way is to adjust until you have about 1" of free play when pressing the pedal with your fingers before you feel resistance. As the clutch wears the free play will get less, check again after the new clutch has a chance to be...

Re: Transmission job.

There are very few if any places within the US with an ambient temperature of 90 degrees F, maybe for a time during summer, but not year-round. Georgia ain't one of them.
That said 40W won't hurt anything.
