Re: Rebuild time

Hi, I think you should first find out what is causing that condition. Sure you can polish it and back together but you may be doing this again and again. Also what about the other rod bearings? How are they looking? Looks like you have a misalignment, oil starvation or lugging condition. I would po...

Re: Fresh Engine Rebuild - No Power

Awesome information guys!! I’ll have a look-see at all of this. I never thought about the other marks on the crank pulley. Paul, will you rebuild a pump for me? Well, yes. The shop where I sometimes work will be glad to rebuild your pump. And, I might well be the guy to do it. You can see our rebui...

Re: Fresh Engine Rebuild - No Power

Yes, I have no illustration with the pointer at TDC.

But, here is a shot that I just took showing the crankshaft pulley mounting flange and the timing mark on the seal plate. This, for use if the pulley is not mounted as it might not be when installing a belt.

Re: Fresh Engine Rebuild - No Power

GP - - All good suggestions so far, and should be checked out. The only other thing I can think of is that the crankshaft must be on top dead center when you have the cam and injection pump triangles looking at each other. If you have the front crankshaft pulley/vibration damper installed then this ...

Re: 92 Charge relay wiring for blower motor

super - - In the P'up the charge relay is used to allow the heater blower to run only when the engine is running. This done by driving the charge relay coil from the 'L' lead on the alternator. One terminal of the relay coil is grounded via a black wire and the other terminal is connected to the 'L'...

Re: Glove box lock operation

Huh? I have owned my truck for 30 years and have never tried to lock the glove box. :roll: So, I went out and tried it. Without being locked I turned the knob CW (from vertical) and the latch pin on top pulls down and allows the door to open. To lock the box, I inserted the ignition key and found th...

Re: 82 pup on propane for added mileage

Greg - - I have not done this but have considered it for some time. I did run some propane into my intake via an adjustable flow gauge one time and liked what happened. Engine got quieter and seemed to be smoother. I did not do this for long enough to evaluate power or mileage. Would still like to m...

I tried to order a GT 1548 about 6 mo ago and found that this one is discontinued :( :(

Don't know if there is another that will directly bolt in or not.

Re: 81 chevy luv wont crank

Assuming you meant "won't fire"-- Even if it's all fixed now, you have some air in the fuel system (you replaced the cutoff solenoid). There's a purge screw on the pump. I'd open it and use the hand primer (with the ignition "ON") until you can see fuel coming out the purge fitt...

Re: Runaway

Hey guys... we finally had a rainy day. Pulled the top off the pump off and the little ball socket on my governor control arm is broke and the fuel control collar that it moves is stuck. Pual nailed it. Time to pull the pump. Thanks for the help Too bad. That ball hardly ever fails and it is usuall...

Re: Engine plate?

That looks like one of the two crankshaft thrust bearings. Don't know how it might have come adrift.

Re: Another,"whatsit"?

Indeed. It is a circuit breaker and it is in the headlight circuit. Just why the Isuzu guys decided to hide this under the dash is a mystery to me. I have had one fail and it was a bugger to find. The failure was corrosion at one of the riveted terminals which I repaired by soldering. Been OK for a ...

Double wow!! I would not have guessed this either. Made all that smoke and power loss?

How did you figure this out? Glad you did.
