U5030 Engine turning socket

[TimboTractor]

Anyone know what size this socket is?
Part number is : 58309-73100
The best price I've found is $185 for the socket.

Wanted to check valve clearance and need something to turn the motor with....not sure how accurate I can get with starter .

Is that an LS part number?

That is a ridiculous price for a single socket!

It is not that bad doing it using the starter. You need a remote start push button set up that you can make with some wire and a momentary push button. That way you can observe the valve train as you bump the engine.

I see your tractor is a 4 cylinder. All you need to do is figure out the paired cylinders. Probably 1/3 and 2/4. What this means is, for example, when #1 is on compression stroke, #3 is on exhaust. All you need to to to check valves on #1 is bump the engine so cylinder #3 valve rockers roll together, meaning as the exhaust valve is closing, the intake is opening (overlap). Stop there and check # 1 valves. Repeat for other cylinders. You should be able to check all cylinders in 4 rotations of the engine.:thumbsup:

That part number is from the service manual but I think it is a Mitsubishi number.
I like the starter idea but don't you worry about the engine starting?
Do you think I can re-use the gasket?

I have no idea the size socket you need, but go to Harbor Freight and buy a set of the large 3/4" drive sockets. They start at 3/4" and go to 2", so there is surely a size there that you need. I got mine several years ago at a sale price of $49 each for SAE and Metric. With large equipment, you shouldn't be without a large socket set. These sockets are not Snap-on quality, but definitely plenty good for the average JOE who needs them occasionally. For the farm, I don't need any socket to be Snap-On quality. I have used mine with 650 ft pound impact gun with no damage.

Gary thanks for the good advice. Do you think it's metric or SAE? I'm thinking it's metric on a Mitsubishi engine.

Metric ----

 

[Gary Fowler]

Definitely metric.

Do you think I can re-use the gasket ?? If I'm careful ? I'm guessing it rubber/silicone....not paper or cork.

 

[jaydee325]

Rubber gasket: good chance it can be reused.
Cork: maybe if it is not hard or breaks.
Paper: slim to no chance.

I'd still buy one and have it on hand, otherwise if it does not turn out, you're stuck waiting for a new one.

Gasket was rubber, had to remove hood, used alternator instead of 46mm hub, 0 on hub is either tdc or bdc (use stick to remove factory paint on inside edge, timing mark very visible, 0degrees to 40 degrees are visible) ie, valve 1 or 4 u can start on, ( the only ones that rock should be adjusted, then rotate to 0 again, do the ones not done previously) , should only have to go to 0 twice, then turn over couple times and check, found a couple loose, couple real tight, need 12mm with nuckle for cover, 12mm box shorty and regular for valve adjustment and stubby flat screw driver. Got rid of a lot of clacking noise on start up. Tightened cover to10ft/lbs, not leaking right now. Wipe everything down ie muffler, cover before you start.

THANK YOU SO MUCH!!! That is really good information. I was worried I'd tear it all apart and not have everything I needed to get it back together. How many hours on your tractor when you did the valve adjustment? Got about 400 hours on mine now and I think it's clacking a little bit. A regular 3/4" 46mm socket is too big to fit in between the crank hub and the radiator. I'll try the alternator trick.

Turn alternator clockwise if you were looking at nut (never came off so I assume it's fine), just turn it slow, doesn't take much effort. Hardest part is tightening 12mm nut while holding the stubby screwdriver with the muffler so close when setting valve, will take some time to get adjustments right. so far so good only ran it for half hour though after finish.
