I have a 2WD B7100 and I want to add some weight to the new rear turf tires I'm putting on it. I've used a weight box in the past but I have limited space in my garage so I don't have room for the 3 point and weight box. I'm trying to add rear weight to offset my snow plow up front. How much...

I know, I know, easier said than done. After many years I've got my B7100 running like a top and restored to original condition-thanks to wolfman and hokie. Would love to add a loader. Willing to buy a "beater" tractor to get the loader. I'm also happy to follow any leads you may have. If you...

...and thanks for the advice 85 Hokie and D2Cat!

Success! I put in three new o-rings and copper washers and no more leak. I also soaked the decomp linkage on the block with PB Blaster and it loosened right up. I also ordered the linkage from my dealer. The o-rings looked fine but they were very hard. I have two recommendations for anyone...

85Hokie, thanks for the info. I think only one of my injector lines are leaking but I'm going to change the o-ring and crush washer on all three. The injector line to the back of the tractor is the one leaking and it will be easier to get to if I remove the other two anyways. I should get the...

85Hokie, I'm getting ready to order the parts. I want to order #6 and #8 both from the attached pic-correct? #8 is called "O-ring"-I'm assuming it's a rubber o-ring. #6 is called a "gasket"-I'm assuming it's a copper crush gasket?

85 Hokie-thanks for the info and the references. I'll dig into the machine tonight.

Please excuse me if I use the wrong terminology-still learning about diesel engines! I noticed a fuel leak when I was bringing in my B7100 the other day. I dried off the area and I did not find any additional moisture. This morning I noticed a decent amount of fuel and I'm pretty sure I know...

Jeff-Yes-cleaned the wire mesh but there was zero carbon or dirt in it to begin with. I just put it back in place before the pic.

I pulled the valve cover and pulled #001 and #003. They were completely clean-not a spec of dirt or carbon. I ran the engine at idle and high speed with the valve cover removed. The only oil flowing was through the lifter arm journals. No oil was being blown up from the valve rods. One idea...

Wolfman, Is the part that needs to be cleaned #003 in the attached pic? Although a prior poster said this oil is normal, especially since this is an older tractor, I don't think it is for two reasons. 1) this tube was always bone dry over the last 150 hours even under a load 2) at the...

Wolfman, I just got home from work and started up the tractor. Yes, I've been using this same oil and oil filter setup for about the last 200 hours. I change both every 35 hours and check oil level every time I run it. I ran the tractor at both idle and full throttle and there is very, very...

The last oil change was 17 hours ago. Oil: Rotella 10W-30 synthetic Oil Filter: Fram PH3593A

My tractor has the 4-bolt front rims. The serial number is B7100-B10565

My 1500-hour 2WD HST B7100 has sprung a leak recently! This machine starts easily and runs like a top. Only normal smoke on startup and under load. No strange sounds and has never used any oil. Two weeks ago I was pushing some light brush around with my snow plow. I was definitely putting a...

Went down to my local Kubota dealer, Messick's, and talked to them. Confirmed that I hooked up the pressure and drain side correctly. The pressure regulator needs to be on the pressure side or you over-pressure the unit. We spent 45 minutes looking for the parts I needed but we could not find...

I definitely had the supply and return line backwards then. I had the pressure line on #1 and the return on #4. I guess that is the root-cause to my problem. Is there some type of pressure limiter in this valve? I'm trying to understand why it's directional.

Thanks for all the info everyone-I feel like we are making progress. Just got back from work and I looked at the valves to see if I hooked up the pressure and return lines wrong. Unfortunately I can't see markings that indicate the pressure and return side on the valve. I took a pic of the...

Thanks for the info. The unit is powered by the block on the right side of the tractor. I've included a pic (I removed it when the valve blew but it was connected at the time). Is there a direction to mount hoses on a block like that? I'm definitely going to replace all of the hoses-I was just...

I'm very new to hydrualics-first tractor with hydraulics. Finally got my new-to-me snow plow hooked up and within two minutes had oil all over the garage. Had the tractor at half throttle and was checking the 4-way plow for movement (luckily nothing binded). When I picked the blade all the...
