Yanmar 2310d won't move

[kfin]

LOL, Winston I had forgotten about the lightning video. Think it was time to get off the water???

I had a vision last night about some c-clamps and an impact. I just was not sure if that was actually a bolt or not before I started messing with it. My manual is as close as you can get to a 2310 but references a screw, anything that I found on the web does the same. There isn't a screw...now that it sounds like it is in fact a bolt I will attack with a bit more vigor this morning and we will see what happens.

Is your axle housing built like the one shown on figure 57 in the 276 parts manual? Reference #2?

Yes Winston, that looks like mine.

I put a couple of vice grips on the drum and the impact wrench took it right off. Did not take nearly as much effort/time as I thought it would to get the actual drum off. But now that that is done, you are totally correct....I can see nothing other than the last 4 inches (what sticks through) of the final spindle are not broken.

Since this thing has gone so long....I want to recap what is wrong, what I have tried and done. As it appears to me the next steps are going to be more interesting.

Tractor was running last fall. This spring it will not move unless the diff is pressed. This is true for any gear and any range. I jacked up the tractor, put it in gear, blocked the diff down and tried spinning the wheels by hand. The right tire would not spin, the left one spun freely. So I am assuming something is broken in the left side somewhere. I was advised to take off brake cover plate and drum to see if the final spindle was broken. It does not appear to be but I can only see 4" of it.

Don't know if this matters or not, but when I turn the spindle, or before I took it off the brake drum, the axle turns. Seems to me that if I can turn either the spindle or the axle and it turns the other one...isn't that what is supposed to happen? Does that mean it is something else wrong?

The left brake rod was not even connected. I didn't know that but rarely even use the brakes, just slow down as the only thing I use it for is tilling anymore on level ground. The "lever" that comes out the bottom of the brake shoe housing was corroded in place. I don't suppose that plays into this? I'm sure it doesn't or that tire still would not have spun would it?

Thanks for the patience guys....I'll await advice here before proceeding as it looks like the next move is to get to the final drive which will require removing the seat, ROPS, and bunch of other stuff I'd just as soon not mess with if not necessary.

Hoye will love the part order when I figure it out as I'm going to fix all the little things that have been ignored over the last 8 years.

Update and another question

Tractor is jacked up on stands. Both wheels are off. Left side has brake off including drum. I started engine and put in gear without the diff and both wheels are turning in all ranges and gears.

Could this mean that it was the frozen brake lever on the left side? Or are they turning because there is no load at all on them?

It took a LONG time, but I got the left brake cleaned up. Took a lot of juice and a wire wheel on my grinder but it actually looked pretty decent when I put it back on. I don't think I will need to replace anything but I will need to order another gasket for both sides. Anyway I tried my hopeful theory about the brake was locked up and causing it....wrong. Worth a shot and got me semi hopeful for a short time.

When I turn it on and put it in gear, both wheels turn but I can grab the left axle with a gloved hand and stop it. So it is only turning because it is not under any load. While it was running I also went to the right side and slowly pushed down on the diff lever while holding the axle from turning. You can feel the diff engage and at that point you cannot hold the right side.

I have taken the right brake off now and got it all cleaned up. Tomorrow morning I will put it back together and back in, shouldn't take but 30 minutes and then back to find the problem.

It looks to me like I have to take off the seat/bracket and the ROPS. Once those are off I can take the cover to the final gear and see down in there. At this point I am assuming that is where the problem is. I still believe it is something on the left side but when the drum was off (on both sides) the 4" end of the final spindle coming through where the brake drum was turns if I turn the wheel axle on that side.

Any suggestions that I am not thinking of? I'm not frustrated yet and have not taken anything apart that concerns me yet. The brakes were filthy. After cleaning, there is very little pitting anywhere and it isn't bad. The shoes are almost new thickness.

Thanks again guys

Just a guess on my part- but it sounds as if you may have broken the left side -side spider gear in the differential 3rd member, or possibly stripped the gears internal teeth or the axle splines that mate with the gear.
If the drive works when the diff lock is activated it may be sending power through the remaining splines on the left axle when the locking collar slides over the axle splines.
It should become more apparent when you get to a point that you can see inside the 3rd member It is also possible to have broken some of the smaller (pinion) gears that are in mesh with the side gears. The good thing is that you have stopped driving it and are on the way to repairing the drive,

Bad things can happen if the tractor is not repaired asap- such as a damaged main ring and pinion when they pick up a piece of broken metal and try to mesh it then things get expensive quickly.
looks like you caught it early, and hopefully it isn't to pricey of a fix.

If you are wanting to inspect further I believe removing the pto assembly would give you the best view. Just an opinion. Comes out as an assembly looking similiar to this. http://www.tractorbynet.com/forums/files/yanmar/179862d1285382386-pto-shaft-snapped-off-part2-jpg

Taking the PTO assembly off now. We will know shortly.
It took a lot of working around and trying different positions but the PTO assembly is now out. Time to check the gears....

I have the pto cover off. Big ring gear on left and right off of axles. Main ring gear in center. If I turn the right axle it engages the spider gears and turns the big ring gear in center. If I turn left axle, the ring gear from it turns and but the main gear in center does not turn at all. Is this normal?

When turning the right gear...sometimes it gets really hard and almost impossible to turn and you have to change direction. Sometimes it "slips" not it is not catching for a short time and then engages.

Where I have "inside space" labeled, where the spider gears are located. The inside part of the spindle going to the axles can be seen here if everything is in just the right place. The right side, when I turn the end coming out of the brake I can see the inside of that spindle turning. On the left side it never turns when turning the spindle that comes out of the left brake but the left ring gear and axle still turn. When doing this on the left side, I can see the spot marked "here" turning, but not the end of the spindle in the "inside space".

Make any sense? Or shed any more light on it?

Just for clarity I will call the large gears on the axle shafts "final gears". The large differential gear is called a ring gear and is driven by a pinion gear. Any chance of pictures up in amoungst them? Wondering if the bolts are sheared that hold the ring gear on the differential housing? Should be about six of them.

I will change the names on the pictures so we all know what we are referring to tonight, on my way to deliver meals for church but will work on this this evening...thanks for the corrections! That is why I labeled them as I knew that was not right. lol

Is it the pinion gear the one that comes out the brake housing?

Where are these six bolts you refer to? Are they the ones behind the brake drum?

What pictures are you wanting? I will definitely go back down and take them tonight if it will help.
