Knocking after 200 hr service

peacefulone · Mar 15, 2009

Wondering if anyone can give me some advice here. I'm a new Kubota owner. Got an L3130 with 200 hrs on it and the guy hadn't performed the 200 service. I had a little fun with it and put on a couple hrs then got all the parts for the service. Everything was working great. Sounds good, ran good. Hydaulics all work good.

Due to all the confusion surrounding the issues noted here of changing only the filters at 200 and fluid at 400, I talked to the local service guy and he confirmed that you can just get the new ones ready, take the old ones off and then spin the new ones on as fast as you could. Then just replace only the lost portion of fluid.

I only lost about a gallon of fluid. I know this because I poured what had dropped in the tray I had under the tractort into an empty gallon milk jug. I then poured a gallon of brand new UDT oil back in the fill tube, measured just to be sure, then started up the tractor.

This is where I'm wondering if I did something wrong. I needed to get it out of the garage, so didn't let the tractor fully warm up before I moved it out into the driveway. After it set there for awhile, I drove it around a bit just wanting to make sure I didn't see leaks. When I got back in the driveway, the thing was knocking in the rear below the tranny fill tube really loud. It hadn't done that before. I checked the manual and see where the 400 hr service (when you completely drain the fluid) says "do not operate the tractor immediately after changing the transmission fluid" and then says you should run the engine a middle speed for a few minutes to prevent damage to the transmission.

Now I'm sweating bullets and really fearful that I messed up. Since I'm new to this, I didn't think I was changing the whole fluid, I was just repacing a little bit. When I did operate it, it was just to pull it out 30 feet into the driveway. Also had to raise the bucket a little to do this. Any thoughts out there? Did I mess up? If so, is it really bad? Any experience with a similar problem that you could share and if you resolved it?

I can't wait to see the replys to this,,I have a 7610 and had the same thing not to long ago,, The service guy came to me and did the service in my garage, I'm not sure if he ran it for long after the change,, The next day it snowed so I started it up and went out,,,there was some knocking sounds like you discribed,, It went away after the first use,,,or did I just get used to it???

Guys mine had that sound sinse day one. When I did my 50 hour service I did it right by the manual and I can still hear it. It don't bother me becuase they all do it. Everyone I've heard does it and it's normal. When the oil is warmer it will be a lesser noise. Remember. There are moving objects inside that case and not just a place to hold fluids. You never heard it before because you had no reason to try and hear it before. Now your looking for trouble thinking you did something wrong.

I'm in the repair business and I see this type of thing happen all the time. I bet your machines still works great. Do you know why? Because it is working as it should and there's now problem. Now enjoy your tractors

Nutt'en to it. Watch my video below and at the 2 minute mark you'll start to hear the same sound. Unless yours is way different than what I'm thinking your talking about. Mine might sounds a little different due to the chain on the PTO snow blower drive shaft guard rattling. If you put you hand on the PTO shaft while the tractor is running (Not the PTO

) you'll even feel it. NORMAL

Fella's, I apologize for two reasons. One........after reading other posts about knocking, I knew this was going to start a thread of debate, but I was worried sick. Two........I found the rattle and feel like a fool. I thought I checked everything in the back that could be loose and would make a rattle. It sounded so low under the tranny. Today, I started it up again and thought I'd give it another try. After a bit, the knocking started again. Again I tried grabbing all kinds of chains and parts to see if they were loose. Nothing would make that sound from down low go away. This time a got under and after a bit of close listening, I grabbed the draw bar hard and worked it out towards the rear of the tractor. Lo and behold, the rattle stopped and all I heard was the purr of the engine. Parts of it had rusted and kept it hanging up in the frame area. So I slid the bar back where it had been and let loose. It worked its way back into the rattle sound just like before. God, was I relieved.

Again........I'm sorry to waste your time and start a frenzy, but I'm feeling incredibly relieved right now. Big sigh. Thanks for those of you that tried to help here. Take care and good luck with your machines.
