Disappointing not to have it drop right into place like it did last time, I know, but still you've done a yeoman job for one day, Rob. It'll probably slip right into place tomorrow when you're fresh and rested.
Ever wonder why they couldn't make those locating dowels about a foot long so they would guide the thing together? Sure would help, huh? I've fought more than one transmission/engine mating in my days and only once had it fall into place effortlessly. One time I must have spent three days trying different approaches to get it and it finally went in without my knowing what I did differently. Go figure. Just one of those cases that illustrates the eternal sonofabitchedness of the inanimate object, I guess. Or maybe I was just young and inexperienced...(grin)
Tomorrow's another day and success will happen.

Rob engage the pto lever and turn the pto shaft from the rear of the tractor ,sounds like the spline on the PTO disc are not quite inline yet,you have to go thru the main disc ,the PTO disc,then the pilot bearing.That last inch is normaly the pilot bearing.We have some that just slide together,and have worked on others for 4-5 hours to get that last inch.Most of the time we take a break come back and it will go together,sometimes we didn't change anything.

Well good morning. Very interesting project you have been doing. Great job & pictures. I was wondering if you manually turned or cranked your engine over after the rebuild by hand with the injectors in. Just looking for some input to compare with what I am doing.

Yes, I did turn the engine over with injectors in by hand. I did it quite a lot in fact as you can see below. You guys who gave advice to turn the splines are right on the money. Instead of turning the PTO, the other day, I was turning the crankshaft with a large socket on it. I had the decompression active so it was easy to turn. I rotated back and forth, but that was not the problem. The problem was that I didn't have the 2 halves square and parallel to each other. That's when I quit. But I went out the next day and started over again with Loretta helping. We split the 2 halves apart to get measurements of when engagement occurs. I also loosened the clutch pack and reset the clutch(es) with my home made "clutch alignment tool", but it was set correctly the first time already. Then I measured both halves and determined the following. This was so that we would now what the hold up was. My calcs told me that the PTO clutch splines touch first when the bell housing flanges are apart approx 1.650". The main clutch splines touch at approx 1.300", and finally, the pilot bearing touches at approx 1/2". Seems to me that should be the first to engage, but it's the last. Anyway, after we got the 2 halves line up again, we tried pushing them together. Guess what? With a little rotating of the crank while pushing together, the darn thing went together! Hurrah!! ;D I used the bolts to suck in the last .300", so I knew the pilot had seated already, and everything was already lined up. Anyway, here are some photos of the tractor back together again. It looks pretty sweet all cleaned up and painted.     |

It took some time to fill all the fluids back up. The radiator, the front power steering hydraulic reservoir, the rear hydraulic reservoir, the middle box and trans (my oil seal comes out when I remove the front drive shaft), the oil filter and engine oil, and finally the fuel filter and fuel tank. Once I finished doing that, I pumped the fuel injector hand pump to prime the system. Then, using the decompression, I cranked it over until I saw oil pressure. I let the decompression knob go and the Kama fired right up.I suppose you want to know the outcome, right? Well, here it is. You can read the oil pressure in each photo. After letting it warm up a little, I took the first photo at about 1200rpm. The second one is at 2100rpm. The third one is backing down to 1600rpm, and the last one, after about 1/2+ hour of running, was at idle 800rpm. The oil pressure at idle after a good warm up was still at 55psi or so, where before it would start to drop close to 20psi.     This just goes to show you that if you try hard enough you will succeed. Man, I'm soooo glad I had the courage to take it all apart again and do the bottom end rebuild to make it right. Loretta and I are very, very happy. All our hard work paid off. I want to take this opportunity to thank all of you who took the time to post encouragement and advice. Many, many thanks to all.

Great news, Rob! Congratulations on another job done well.
If my tractor ever needs that sort of major surgery I'm not even going to screw around. I'll just send you a plane ticket. (grin)

Rob and Loretta, Great news and great pressure (pun intentional) , I think you are both incredibly brave to have it apart a second time , I'd have thrown something at it (heavy) and sulked for a week !!

Rob and Loretta, Great news and great pressure (pun intentional) , I think you are both incredibly brave to have it apart a second time , I'd have thrown something at it (heavy) and sulked for a week !! Dick Thanks Dick, Don't think I wasn't thinking the same thing. I was soooo close to saying "screw it, I'm selling it". But I got to thinking about all the stuff I've done with that tractor ... all the improvements and modifications I've done to it over the years. I just couldn't get rid of it. Most of the stuff I broke (other than this) was due to operator malfunction. Which I could've broken on any other brand tractor ... regardless. Crashing into a boulder and snapping off a tie rod end for example, or churning the gears forward and backwards at high speed with 2,500lbs in the bucket in 4wd stressed and eventually broke my front drive gears. All those things would have screwed up any other tractor too because they warn against doing so. The little annoyances of owning a Chinese tractor like things not being machined exactly right are easy to fix (but annoying nevertheless). The electrical problems, which I know nothing about are a pain too, but now, one phone call and "POOF" Larry is here to fix it in 9 minutes. So I can live with it. I figure I've saved at least $100,000 (no shit) in dirt work, backhoe work, road work, plowing, mowing etc. Quite an outstanding return for a tractor that I paid $10,800 bucks for. Throw in the Koyker loader with 72" bucket, an 8' Nardi Backhoe, a Howse 6' Rotary Cutter, my famous 7' Howse Boxblade and Leinbach Post hole digger, the package went all the way up to $18,500 for all of it. I had to pay $2,000 for shipping to my property, so if you count that the total was just over 20 grand delivered to my doorstep (campsite back then). Not bad for all that I saved. How many guys can say (truthfully) that their tractor has paid for itself 5 times over in 4-½ years? Great news, Rob! Congratulations on another job done well. If my tractor ever needs that sort of major surgery I'm not even going to screw around. I'll just send you a plane ticket. (grin) Rich I'll gladly take the ticket Rich, but not to work on your tractor ... lol. The Virgin Islands had always been a dream of mine, to visit, vacation and play some golf. You are one lucky dude!  It's been pouring here as I see it is over much of our state and others. Even so, I think, later, I'll take Huge Kama out and hook up the FEL and maybe the backhoe. I am still in a semi-unconscious state of shock that it runs so well and smooth, with a lot of oil pressure. I was also gonna go pig hunting earlier today because I saw rooting ALL OVER Murder Meadow right in front of South Camp where Larry and Ken stayed when they visited. But I couldn't wait to check out the forum first. Rob- |

Very nice -- I think you should go kill something to celebrate ;D ;D
Some smoked wild pig sounds pretty good!

Thanks guys,
I did go out there very early, but no sign of the pigs.
It was drizzling and cold, but I figured a perfect atmosphere for those pigs to come up from the river. This is the first time in 5 years I've seen them come onto our property. Usually, they stay right by it unless it's raining and overcast.
It was cold and rainy (again) today.
Nevertheless, I put my rain gear on and ran the Kama for several hours. I put the loader and backhoe on yesterday, and was planning on trenching the areas in front of the culverts. I got 2 of them pretty well cleared and flowing very good. Sorry, no photos. It was hard enough to try to smoke a cigarette without crumbling it in the rain. Hot coffee was good though.
The Kama ran excellent for the couple 2 or 3 hours I put on it today.
Oil pressure stayed at 60psi around 1650rpm. And when I brought it down to idle, it went down to 50psi. So I think that little test let all the new components settle in to each other. I also dug a little bit in the pond area, but it was so muddy, I only spent a half hour in there. After that, I actually hosed it off to clean it up a little?
Rob-

Congrats Rob & Loretta!
Beautiful Job, the paint makes your tractor look very custom. I was very impressed with your fortitude for the first go around and all I can say is WOW, for the second go round. It seems now that it was worth the extra effort. I'm very happy for both of you that you got your deserving result.
Again, awesome work, thanks for sharing it.

Man - I can't wait to see what you do for the third act!!! Doh! Hopefully it's an upgrade rather than a repair.  If I had a vote, I would vote for a loader quick-attach. ;D Congratulations Rob and Loretta! You make a great team. Brad |
