Added some more weight to it today.

Question:  how hard do the rear wheel pull off those splines?  I've heard horror stories about how stuck they can be.  On the 9 series and 6 series as well.

One side came off extremely easy due to the axle seal failing and greasing the splines over the years.  The other one was a different story. Block of wood and sledgehammer with some tension with a puller. Got it to start moving and then just took our time moving it back and forth with some WD-40 and patience.  It had some rust built up but nothing terrible. Didn't pit the splines hardly any.

I see you're handling 8 bolt hubs.  Missed that detail.  I was more thinking splined castings like earlier W series.  I've read stories of people digging a hole in the ground to lay the wheel flat with the axle down and pounding it free of the casting.

I see.  I've never dealt with those before.  I can imagine they could be tough.  This tractor was pretty rusty, but everything came apart fairly easy I'd say.  Only broke one bolt I believe and it was on a fender bracket.

A little mock up. 23.1x26 tires are massive.

Looks bad*ss!

We've been super busy trying to get our crops in here after a very wet May.  I have the rims ready finally and need to get them primered so I can mount the tires. I'm going to top coat them after they are mounted. Not sure if that's the right thing to do but that's where I'm headed.  

Have my local propane supplier getting me some valves.  I'd love to stay with original but made the decision to upgrade to new valves and pop-off safety valves and be on the safe side since im going to use the stock tank.

The Ohio Chapter 6 state show is the last weekend in July/first Aug and I'm going to try and have it there. I may just take it without the sheetmetal done if that's where I am with it. Goal is to put it through its paces first to see if there are any items that I missed that need addressed. 

[IH Blood 1206]

Service valves rebuilt, new pop-off to replace the original, and fill valves installed. Paint next.

Doing some old school farm work today instead of working on the 650.  First time ever cultivating corn. Rode on the fender as a kid but never did it myself. Ground got pounded after we planted so we are helping it out.  674 Diesel with IH 6 row.

Haha yeah for some reason it feels right over here. We have an 84 Hydro that has pretty much the same setup, with the forward and reverse lever on the left. Feels awkward sometimes now that we are all used to foot controls for forward and reverse. 

The 650 has been fun. Hope to have it ready for a show in August. Going to be tight. Im not going to rush it to get it there. It might go with unfinished sheetmetal. 

[IH Blood 1206]

My son started the cleanup on the fenders. We had the originals and another set we picked up in Indiana when we went on the trip to Nebraska to get the hood. We are going to use the two best ones. Had to do just a bit of straightening to one and have some holes to weld shut on the other where some fender extensions were added at some point.

Finished off my gallon of primer today. Hard to believe I've went through an entire gallon. Guess that's what happens when you take it down to bare metal! 

Second time for the rims.  Did the fab on the one and then added the body filler on the other. Turned out nice.

The tank is a pain to paint. Was able to lay it on its side and paint the bottom and then roll it over for the rest. The finish coat will be a little trickier. Prob just hang with chain from the engine crane. We will see if a better idea pops up between now and then.  

 

Also, was searching some pictures of other 650s online and came across one that had some hand painted letters on the side of the engine block.  Same as mine.  Kinda cool.

Also while searching pictures, I came across a 650 that sold on auction last year i believe. Serial number 4295 I think. The gas engine serial number was 1072 or close to it.  Mine is 1033.  My serial for chassis is 3141.  So they made roughly 1150 tractors after mine and were only about 40 gas engines further. Goes to show you how much the diesels outnumbered the gas/LP, assuming they stayed in somewhat of an order on the blocks.

I have a block with yellow hand painted letters also.  I think it’s on my W-9 block.

Have had a few rainy days here. Had to change the unloading elbow on our 6088 combine. The new elbow was being stubborn but we eventually got it in. The old one had worn a hole in it and started to buckle running corn last year. 

The Ohio state IH show is near us this year and they are featuring the '06 series.  Our 1206 last ran about 4-5 years ago. I know, a crime. We try to run it more often but the last few years its been sitting. 

Put new batteries in it last night and it fired right off. My son drove it to our main farm today. He heard it run for the first time ever yesterday.  4th generation to drive it.  Pretty cool. Time to get it all cleaned up and ready for the show in a few weeks.

Primered a few more parts for the 650 tonight. Hopefully a topcoat on them tomorrow or Saturday. 

[IH Blood 1206]

We couldn't help it. Had to have them face off.

[Illini986]

Couple sharp machines right there. Can't wait to see your 650 when it's all said and done. 

[IH Blood 1206]

Slow progress. Have been busy and spent some time on vacation.  

I think i have the grille finally ready for some filler in a couple spots and then paint. Had a lot of tedious work to do to it. Three cracks to weld and numerous bars to straighten.  Wasn't the best grille to start with but it is what I have. 

Got the gauges in the cluster. Need to hook everything up once I get the tank back on.  For the correct police, yes I know its the wrong tach. It's just a NOS one I had here. I would love to find a 1500 rpm that is correct for it but I haven't been able to find one yet. 

See what this week holds. Prob start running wheat this week sometime.

[IH Blood 1206]

I just can't get over how massive this thing is going to look.

Picked up tubes for the rear tires today. $135 apiece. That's plenty if you ask me. At least they are Firestone and not some off brand.

Been really humid/rainy and hot here so no painting. Maybe later this week.

Looking good!   We finally rounded up enough engine parts and got the machine work done but have been too busy to put the engine together on dad’s 650 LP though.   The flange on your start button goes on the back side,  do you have a light for the gauge pod??

The flange holds the button down.  Not sure how it could go on the back side. The one on the tractor when we got it was like this. Yes I have the light, it isn't ready to put on yet.

[snoshoe]

Yeah the flange goes on the back side. So does the switch. Just the button sticks through the hole.

I stand corrected.  Thanks guys. Hadn't had a chance to look in the book yet. 

[IH Blood 1206]

Found another 650 LP in the wild today.  Mostly complete but is stuck and doesn't look good. Might think about it for a parts tractor.
