Vic's bet re. 3 pt hitch problem

[PeterA]

This is a follow-up to my thread of 13 January 2011 re. my 3 pt hitch which is slow to go up. Service Dept. Vic bet Mr. K. that the problem is dirty hydraulic oil strainers, suggesting that they have been infrequently if ever cleaned. At stake is "a round of extra large double-doubles at Timmies and a box of apple fritters for the shop crew."

I pulled the oil strainers out this afternoon, so here are the results. The appended photos show both the left (fat) and right (skinny) strainers, either by themselves or along side a new strainer (which the local Kubota dealership gave me gratis). I've also included a pic of a measuring cup filled with kerosene that I used to clean the strainers (with a toothbrush).

The left strainer had tiny metal shavings on the screen. I cannot really see through it when I hold it up to a light, whereas the screen on the new strainer is somewhat transparent. I have the left strainer soaking in diesel fuel over night.

Do these photos give you enough evidence to support the conclusion that the strainers are "dirty" and therefore provide a determination as to who wins the Timmies bet?

Should I be worried about the tiny metal shavings on the strainer screens?

Okay, that's all for now. Thanks again for your help with this problem. Back to you Vic and Mr. K.

Here's a couple more photos to go with the last thread (max. 5 photos allowed per post).

Further to the last posting, I will either install the old left strainer or the new one depending on what the former looks like tomorrow after having spent the night soaking in diesel fuel.

I'll give the 3 pt hitch the ultimate test shortly thereafter once I get the hydraulic oil back into her, namely, a start up. Low of -12 deg. C forecast for tomorrow, high probably around -4 deg. Shouldn't be a problem starting her up.

You guys are great! I figured SDV would be right - you be the man ! Hope the fritters are good.


Hey - SDV - how about creating a video about doing this? Sounds like this is something everyone could benefit from.

Vic. I put the hydraulic oil back in this morning (at -14 deg. C) and started her up. The 3 pt hitch now works like a charm. Beautiful!

The only weird thing is that after a couple of minutes of operation, and with just the engine running (no use of FEL or 3 pt hitch), some creamy white fluid started pouring out of the top of the transmission under the seat. See appended photos. About 1/2 litre came out and then it stopped. Is there some kind of a pressure relief value on top of the transmission?

I put exactly 13.5 l of hydraulic oil back into the tractor as per the service manual.

Thanks again for your help with this. Peter

I figured some one else would have replied. But here is what I came up with when I did the same thing. The amount of fluid listed is the amount when everything is dry. Draining the fluid doesn't get everything so adding the full amount overfilled it and it spilled out the vent.

Your bigger problem is water in your hydraulic fluid. I will be doing my second change tomorrow hoping to get mine flushed out. Mine is a b7100 and I can't find a way to do the hose into a bucket of hydraulic fluid to flush it out quick.

Apple fritters is it? Jeesh... second time this week.... I'll be back in 20....

PS. Good post! Like the pics.

Speaking of those hydraulic screens where are they in a BX24? My system seams to be a bit under powered lately.

Thanks again Vic. It's probably not good for the waistline to be winning too many bets with Mr. K, so I hope you ration the bets out a bit.

I decided to install the new strainer (left side, fat one) seeing as it was free, but most importantly because even after a night of soaking in diesel fuel and blowing with compressed air, the old one still didn't look that clean. I don't think there's any easy way to get years of muck out of the inside of these things.

Do these strainers/screens have a limited lifespan, even if they're not punctured or torn? It seems prudent to replace them on older machines if they haven't been subject to regular cleaning and inspection shows them to be very filthy.

The right side strainer wasn't very dirty, as proven by holding it up to the light. You can see a kind of metal coil running through it beneath the filter screen. It was pretty transparent.
