D7H Transmission Filter Dilemma

Have just taken delivery of a D7H, 5BF 06261, zero hrs since trans. filter and oil change
Worked for two hrs. and trans. filter bypass warning activates.
Pulled filter, 132 8876, only examined externally but looks clean.
SIS is a bit confusing, at least for me, as it lists both this filter and 1R 0741.
First filter is ulta high efficiency and probably not suitable for transmission use.
Hoping someone can point me in the right direction.

I wonder if the zero hours on oil and filters tells a story.You say you just bought it or took delivery.
I think those UHE filters are for clean up only and need to changed when light comes on until clean.
That’s assuming it’s not currently making metal.
I hope it’s ok for you

G..G..G..Granville.........!! Fetch your cloth.
Cut the old filter open and squeeze a section of it in a vice and have a look would be my first suggestion. I like running UHE filters in power trains, it helps keep them clean and prolongs component life. It may be nothing more than the new oil was not as clean as it should have been and the filter is cleaning it up. Wouldn't be the first time.

SIS shows me 139-1534 for the power train filter for your S/N which services to 132-8876. No mention of 1R-0741.

The 164-7577 filter bypass switch are notorious for failing, or at least getting tired inside. I'd have a look at that switch and while you're in there take a close look at the 9M-1986 Spring in the bypass valve. The free length should be 47.2mm.

When you've done all that the attached Service Mag might be of some interest.

According to the service mag I could try 343-4465, so now we have three filter choices.
When searching on sis, this is the other option that leads to the 1R-0741 number.

We had Cat do a TA2 inspection on the machine but that would/should have happened before the oil and filter change, no issues found there.
Have had the switch, spool and spring out just to check operation, continuity etc.
Didn’t have spring spec. then, so we can check that now.
After start up it takes a couple of minutes of mid speed idle to activate the warning, will go out on low idle.

I found the 139-1534 number by going directly to the filter rather than via the PT oil lines. That's also where I found the Service Mag SEPD1230 regarding the optional elements. I think on the one you looked at the filter P/N had not been updated from 1R0741.

343-4465 is the latest iteration of powertrain filter if a customer does not use UHE elements in that system.

I’ll talk to the dealer later this morning, confirm the oil and hit him up for a new switch and spring.
Try that first with the UHE filter and go from there.

Yes, it does have a SAE50 TO4 in it.
I’ve always used a 30 here but he sells a lot of tractors into the north (tropics) and puts 50 into everything apparently.

Can't help you fix it Queenslander, but am surprised you are able to work that heavy jigger at the moment, being so wet.
I got the truck bogged the other day trying to back into the ramp at the yards.

We couldn’t even get the float right in to our place for fear of bogging it on an unsealed river bank that was under water just last week.
Unloaded the tractor, walked it to where we hope to pull some fairly high ridge country and hooked up the chain when the alarm sounded.
Maybe it’s trying to tell us something.
More showers forecast later this week.

Have only done a couple more hours but a filter change to 343-4465, a advanced efficiency filter, seems to have solved the problem so far.
Not sure I have enough TDTO 30 on hand to change oil straight up so will run for a couple of days and change oil and filter again.

I was once a big believer in SAE50 until I got involved in some research into transmission clutch engagement times and saw the difference in time to reach full clutch pressure between 30 & 50 in the same transmission. This led to extended clutch slippage during engagement and was causing lower transmission life.

Now I’d only use 50 if there was a very specific reason for using it and not just because the O&M recommended it for the ambient temperature at the job site.

The 0 to 35c spec for 30 is a better fit for us than the 10 to 50c for 50.
Anyway, thanks for your help once again Nige, I would never have known about the filter upgrade without reading the service bulletin that you posted.

Quite unusual to see it like that in August. Good to see though for a change. Are they planning on stickraking what they are pulling? Otherwise looking at the recently tordoned timber makes you wonder why pull it. I have been taking out the crappy iron barks up here. Ordinarily we would leave them, but it turns out the ones we left end up dying anyway. The Moreton Bay Ash trees here have turned into a real pest. They are worse then wattle in places. We suspect after cyclone Marcia came through it germinated billions of seedlings, mostly along the creeks. I am lucky I have not got much of a problem with them, but some of the neighbours have some work to do before Queen Anna loses popularity and decides to take it out on farmers once again.

RC, this is on our place, and it was chopped about four years ago.
The plan is to get the dead timber on the ground and get a decent fire through it.
The grass growth, from a combination of response from the chopping and the terrific season, has been unreal.
Just need some hot dry weather, but we may not see any for a while if the forecasters are right.
Certainly pulling well, but we’ve decided to knock off until it dries out a bit…too hard on the nerves.

Ahh OK. A good fire if you can get one this year should burn a good bit of it up plus rejuvenate the spear grass.

I would bet some seca and siran stylo would grow on the ridges there if it is not already there. :)
