The local machine shops only have the line hone machine that goes through all of the main bearing caps. They require that the centerline is both aligned and the same size. The machine they have would delete the rear main seal. I do wonder if it can be done with a lapping bar much like you would...

Well, I cracked open another block and it turns out that nobody's crazy. I just have an anomaly block. The bore with mains torqued on the 2nd block came out at 3.142" and a Std. set of main bearings will work perfectly. I understand the "select fit" but that was to mix and match Std, .013, and...

I will look into that. Thank you. I ordered from summit and haven't looked it up from the nsn

You're not wrong to ask. They are for a 6.2. With a variance of .0035 between bores getting. 0018 tolerance across the board (1-4) just isn't happening. Crazy because the stamp in the oil pan face says #2 across the board but they are all different sizes. The gm manual says they were select fit...

Thanks for the help. The problem is that the bores in the block are too small, not too large. #4 is negative and will not even allow the crank to turn if torqued. I have seen std, and undersize bearings but those refer to cranks that have been ground and are actually thicker bearings to make up...

I could use some help from someone that has rebuilt a 6.2. I'm trying to rebuild the engine from my M1008 and the main bearing diameter are all different sizes. I put the main caps on without the bearings installed and the hole the bearing goes in ranges from 3.1389 (#5) to 3.1424 (#1). The GM...

I bought a M1028 last week and the generator /welder was gutted from the back. I could use some guidance from those wise on these things. Would it be better to use the space for a newer stand alone engine driven generator/welder? If so, which one? (NP208, no PTO) Should I replace the original...

Thanks, I figured it would steer something but I wasn't sure. Especially since the fit was pretty sloppy.

Can anybody tell me what this was used for? It was slid over the end of the steering knuckle and the tie rod end went through the hole in the middle. It added the forward hole that would have moved with the steering but I can't fathom what for. It came off of a 1990 K20 Suburban 6.2l diesel that...

I'm with you on the Ford parts but $20 each for my steel 1ton junk yard rims off of a Ford cargo van couldn't be beat. As for the thermostat, the one in my cooling system is 190. I would get an electric fan thermostat at 195. That way youre not running the fan until the truck needs it. If you...

Electric fan install Ok, sorry for the delay but my phone wouldn't let me reply properly while I was out. Here is the install thread for a Ford Windstar fan into a CUCV. http://ck5.com/forums/threads/dual-circuit-windstar-fan-final-shroud-update-05-11-11.267400/ There is enough room once the...

Any auto parts store. Tell them you want a thermostat wiring harness for an electric fan.

Look up ford windstar electric fans. Igot mine from a junk yard for $14, + $35 for a thermostat control wiring harness. There are some great writeups on it.

After, following every wire, it turned out to be the battery to frame ground. It felt solid but was only slightly corroded under the cover. I put on a new end and problem solved. pm me a good number and I'll talk you through the trouble shooting if you still need help.

Tested about two weeks ago

Just to update you guys, I took the alternator in question to a real alternator/starter shop and they replace the voltage regulator. This presents another problem. You said up front to look at the ground and I think I may be back to that. I removed the ground wires and from pole to pole I get...

Ok guys, First, thanks for your help this far and sorry for the delay. My day job still gets in the way of play with the truck time. I checked the ground on alt 1, the cable seems solid, did a resistance test with the ohmmeter and it looked good. I ran a jumper wire from the ground post to the...

not across the alternator posts, only from the battery post to an engine ground. I'll check it tomorrow and see what we find

Yes barely. When i turned everything on to load test the alternators the voltage dropped to 22 ish.
