Thanks again.

I'll just add that IF the pin was sheared you possibly wouldn't notice it as all the pieces would be held in place, and if the shaft had a little friction it would appear all was well. I'm just giving posibilities here.
I really hope it is ok!!

WOW your going to part a super to put power steering on a 782?

If I were closer Id take the rolling chassie off your hands. Id like to make a gear drive super. I have some engs and Id run a pump off the crank.

Well, we have good news, and bad news.

First the good.............................................. .................................................. .................................................. .................................................. ...................... Oh wait, there is no good news, ok on to the bad.

I pulled the plugs, and the lines going to the remote filter. Then spun the engine with the starter, trying to prime the pump. I thought I was seeing some oil coming up the pressure sender port, then the spinning stop. The motor froze up. I had some errands to run, so I had to leave it. Got back, pulled the motor, tore it down, one of the rods is spun.

Can you say "start over from scratch?"

I'm hoping to use the dual rear brakes, front hydro ports, and the power steering. Then yes, peddle the rest.

When you put the eng togeather did you use oil as your asembly lube or grease? I use grease. Also did you put a new pump in, or is this the pump that was in the eng?

On another note I was thinking of your heads last night and remember theres a guy on another forum that rebuilds carbs for motor cycles and he uses a soda blaster. So I got to looking at home made ones last night and going to build me one for carbs and Im guessing it would work well on the heads too.

That sucks, hope it's not too bad.

Vince

Don't hold out on us with the soda blaster. Inquiring minds want more info.

Now I have that feeling in the pit of my stomach, Aw Sh**
Sob and other words,-------
ok,
looks like the crank can be cleaned up/saved,
but it will need a rod. but WHY didn't it pump oil, is the question!
did the block have that problem when it was a gen set?
the letdown is a bummer to say the least!
I feel your pain!!
Now I really want to know why no oil, as well as you

I chucked the crank up in the lathe, started with 320 grit, then worked all the way down to croakus cloth. It looks ok. There is one area where it is .0005" small, but it is still in spec.

As far as the oil pump, it is intact and appears to function as it should. The only thing I can think is the the dummy that built the engine didn't use enough assembly lube, and failed to correctly prime it.


Oh wait, I'm the dummy that built it!!!!!!

I belive that the addition of the remote filter, may have played a part. The filter did have some oil in it, but it never filled all the way. This time I will be more generous with the assembly lube, leave the heads off, and prime it on the bench.

[Sam Mac]

Just a thought but you may want to use a small pump or some kind of tank that you can pressurize to prime the system before turning it over. I'd hook it up to the line that feeds the filter.

[MWShaw]

Yes, That's what I'm noodling on. I will fill the filter, and lines prior to ever spinning it over. I have some thoughts on how I will prime it, I'll post more when I sort it all out.
