OK, all testing before was done in 4-wheel drive because I leave it there all the time and never thought to take it out. I lifted all wheels off the ground and the rear spin fine by hand, the left foot locker pedal works fine, the front spins freely too but when the 4-wheel drive system is...

Well now it's making a popping and gear crunching noise every few feet that bogs down the pump while its crunching!!! Doesn't matter what gear your in. Does it in Forward and Reverse.

1st off the fluid level is fine, I was out grading my driveway with the B21 and after about 10 min. I was backing up using the bucket to level some gravel and I heard it make a weird popping noise and then the tractor quit moving, pressing the forward or backward foot pedal just made the...

Thanks, I've rebuilt lots of contraptions and been a machinist for 37 years, I think I might try it, where would I find a part # for the factory o-rings?

Care to elaborate on that? Is it better to remove the whole pump and do it on the bench?

I just found this topic that describes how to fix... You CAN repair a leaky fuel injector pump! PICS and a question.

Thanks all, I have line wrenches I can use on them, if that doesn't fix it can I remove the barrel flange and replace the o-rings without removing the pump?

It's started leaking a LOT more now, I didn't have any powder so I tossed some baking soda on it and saw this. I checked the fittings with a wrench and they are tight.

Thanks, I' give that a try.

I've cleaned and watched it start leaking twice, and I see no fuel above the injector body. So I just assume it's leaking at the shim gasket area. Guess I need to check how tight the screws are first.

It's leaking fuel, about 1 drop every 5-10 sec. I'm still using the tractor, I just want to know how to fix it when I get time. So the shims serve as gaskets too?

I have a slow drip and it looks like a leak where the Green arrow is pointing, best fix for this is? Thanks in advance.

Thanks, I was hoping that was the case.

Kubota B21 with BT751 backhoe, a pressure relief valve has rusted to where it's leaking badly on my main control valve, it looks like it may just unscrew and come out, or do I have to disassemble it further to replace it??? And it's strange that one valve rusted badly and the others just have...

For awhile now on my B21 I would sometimes have to cycle the ignition switch ON/Off and back to the glow plug position several times to get the glow plug light to come ON, now it won't come ON at all leading to long starting times, do you think the key switch has gone bad???
