No problem. While you have everything apart also check and replace the drive shaft ball coupling that is in front of the transmission case. When I checked mine it was shot. Worth putting alignment marks on shaft and coupling before separating.

Ah yes I did this job last year. You separate and roll back the rear end about a foot and this is enough to allow you to pull the shaft out of the tunnel ,fit the seal and replace the shaft. It's a little awkward getting that seal in straight but persist.

This is what threw me a bit. The nut which is called "nut left" in the parts manual (it's on the right hand side as you face the tractor) loosens, on my tractor, turning anti clockwise i.e. RH thread. I am going to have to use some force to shift the other rounded lock nut so want to be clear...

I'll take it off and get it to the machine shop. I would like to confirm that the lock nut on the left side as you face the tractor is a left hand thread ie will turning it clockwise loosen the locknut from the tie rod? The lock nut has been badly rounded by a previous owner which raises my...

Noticed just today that my front wheels were way out of alignment. When I attempted to adjust the tie rod I could not get one of the locking nuts to shift. I then realised that the tie rod had been bent rearwards at some time in the tractor's long life. Can the tie rod be effectively...

I've driven my B7100 on steep country for 15 years. Set the wheels to the widest setting and 90% fill the tyres. I use my 4 ft rota cutter on the rear end and have a big concrete block for counter balance strapped on the front end. Anything more I would regard as excessive for this size...

That oil may likely to be coming from a leaking front axle pivot pin seal. The pivot pin on the B7100 passes through a cavity in the front diff and is lubricated by diff oil. I had a similar leak on my B7100 for many years and finally got around to replacing the pivot pin and seals. Put a...

Very informative thread; thanks to all posters. My B7100 is up to about 4000 hrs . Still starts and runs fine but I have saved all this useful information for when the time comes. The way it keeps going ,that might be when I'm in the ground.

There have been a few posts from members uncertain about those plugs. Your dealer is right. However some members incuding myself have found oil from a leaking front diff seal, and other gunge , sitting in that "can". It is worthwhile and straightforward to undo the 3 bolts attaching that...

Just realised I had a sizeable hole in my B7100's lower muffler. Is this likely to cause back pressure and explain blow by from the rocker cover ventilation pipe? The tractor has done maybe 3000hrs but still starts first time and is not going through any oil.Just a lot of blow by......

I have 4 different manuals for my B7100 , one of which is the "Kubota Technical Manual B5100 ,B6100 , B7100 ". Does anyone else also have this manual ? In the Glowplug section it states (in very broken english) that if one glow plug fails then the other plugs and the indicator will continue to...

Thanks Don......and my last posts were my best work yet :D

I submitted a number of posts last week that have disapeared. I just noticed there seems to be no posts at all recorded on this forum between the above dates.

A B7100 that never glowed, that I can see , in over 15 years. I usually have to pre heat for about 20 to 30 seconds (in a mild climate ). Does that sound about right ?

There are seals in the throwout bearing carrier and they were,for me, a pain to remove . Probably also worth replacing the bellhousing shaft seal which is awkward to get at. I used a pilot bearing puller to get my one out. As birdog suggested , check that universal coupler ; mine was shot and...

Split my 1980 B7100 last year and did the same job. After putting it back together I had clutch shudder. Turned out that CV joint at the end of the drive shaft in front of the transmission case was worn and sloppy. This old girl has been worked hard for 15 years, often neglected...

You're right on the money Drescruis. Found all of the above problems. Seal behind brake drum is seeping just a little oil so I've ordered a new one. Also, when I fitted my aftermarket brake shoes the brake drum wouldn't fit over them Had to grind the metal on the ends of the new brake shoes...

As there seems to be no manufacturer's spec I have used the torque chart for 12mm and 14 mm standard type bolts and tightened them to 50ft/lb front and 85 ft/ lb rear for the moment and will check them now more regularly. addit: the design of the new hubs is terrific.

Exactly . Nothing in any of those 3 manuals and nothing also in the Technical Manual.

Does someone have the front and rear wheel nut torque specs for the B7100
