rear wheel bolt size?

kempryan28 · Oct 31, 2019

Hello everyone... I'm the proud new owner of a Yanmar YM276D. I can't wait to tinker with it and make it mine.

For starters it has a flat tire on the rear, when I tried to put air in it the valve stem broke off due to dry rot. The other side looks just the same. So I plan on taking the rear wheels off and bringing them to a tire shop to get fixed up.

My biggest question is what size is the wheel bolt on the rear wheel? I want to be sure I head up to the property with the right tools so I don't end up stalled before I even get started. Also are these inner-tube tires? Calcium filled? Any thoughts, tips or tricks would be great!

Thanks,
Ryan

I have researched it a bit and found various results... mostly anywhere between 22mm and 26mm. thoughts?

If your valve stem broke off you probably would have had some indication right there had the tires been liquid filled. I can't help you with a socket size for wheel removal but get a twelve inch extension to access the bolts more easily. Be sure the tractor is jacked and blocked securely before attempting to remove the tires. You do NOT want it to shift when off the ground. Even without liquid filling the tires and rims will be heavy. Be prepared. When I replaced my tires I had the tractor jacked to the point the tires were JUST off the ground. I could then roll them over to my trailer and tip them on, minimizing lifting. You may be lucky and need only to replace the tubes.

I also have a 276D. I use a 6 point SAE 3/4" socket set to remove the wheels. No idea on the proper size, but can say that there is no need to use 3/4" metric sockets if you don't own them.

I block the tractor up securely. Remove the tire, place it in the bucket, raise the bucket, back the pickup underneath, and deposit the wheel in the pickup bed.

If the tires were fluid filled - you should have got some kind of indication when the valve stem broke off. Repeat what Roadworthy said. Block it well and be prepared for a HEAVY tire.

Tubed most likely. My YM2000 are and Hoyes Rear tires are for the 276. I started to dry rot and crack and had trouble with Tubes. If you have slices or cuts like my Org. Rears you can go this route which worked great for me. They have gone up in price but I noticed why. They've made it steel belted now.

A 19mm and a 3/4” socket are the same size.
Sorry, I have no ideal on the bolt head size on a YM276. In my YM2002D on the rear are 22mm.
Someone suggested a 12” extension, if you need to use an extension, use as short as possible a as it will require more torque.
Also my tires front and rear are tubed. If you have fluid filled rears, you will know as you rotate the valve stem toward the bottom of the range. Tires are filled to around 80% capacity. So you should know by the time the valve stem opening is near 10 or 2 o’clock

I do have a upgrade on my YM2000 2wd. front axle which is easy to notice. The Bearing cap has 4 screws which attaches it when most Axle Bearing covers press in. @21mm Wheel mounting Bolts. The Impact set I had available real quick has a 27mm / 1-1/16Stn. It would work but If I recall I used a 26mm for a better fit when I removed the Rear wheels. Also On my Rear cracks this is how bad they was getting. Done this Quite a few Yrs. ago and as you can see the Lugs are still HUGE!!! I came to realize I''ll never wear them out most likely.

Thanks everyone! Great help. It will be secured well and I plan on using an air impact set for removal so should have plenty of room to work and torque. I hope to do just tubes as I too have tons of lug left. I値l cross my fingers and give it a go.
