- International 1066 Full sized JCB Loader/Backhoe and a John Deere 430 to mow with
Had a most pleasing Sunday afternoon. Machine is a JCB 1550B, full sized industrial backhoe/loader.
Long story short...about 5 years ago, was clearing some brush from yard on side of house (pushing tree line back & making new lawn)
I ran over a branch which angled up and speared my transmission filter AND it seems, behind my filter, I have some kind of high pressure transmission port (for testing purposes??)
The filter was speared through the heart and the pressure port was also buggered up so I replaced both items.
Ever since then I have had a slow drip in my trans fluid. Just a spot the size of a 50 cent piece if sitting idle and if machine is running, it might grow to size of an orange.
Friday I needed to get some stuff done so hopped aboard and noticed it was now dripping almost continueously. To the point that as I drove down the road I left a drip line.
Getting concerned that I had physically damaged the filters housing or perhaps damaged the high pressure port thing.... yesterday I decided to be relentless on digging into this and finding out what the deal was.
To be honest... I was already realizing in my head that I was not going to spend the cash needed to fix this transmission issue...so now what? scrap the machine? part it out and keep the engine so I could mate it with a generator?? what to do....
Well... I crawled under there, changed the fluids and filters, presuming I had a bad seat on the filter. Nope... machine on...transmission fluid was just dripping out. Not really under any pressure per se' but otherwise flowing MUCH more free than it had for the past 5 years. Clearly my problem has grown so I should easily be able to detect it,....right?
Nope.
Once I detected the dripping again, I looked closer. The oil was coming from ABOVE the filter... hmmmm.... shut down, removed the filter and looked further.
Dont you know...this high pressure port is placed horizontal with the ground. It has two parts to it. Seems I replaced only one part. The OTHER part is the base.
This base connects to the machine via a 1/4" type port (think of your water supply tubes under your sink)
Seems when the filter got impaled years ago, it must have wrenched the housing of the pressure port counter clockwise and loosened it just enough to allow a dripping of fluid.
Over the years, vibrations have loosened it further.
This stupid thing was finger loose...and I had a lightbulb moment!!
Got out my wrenches & tightened it down and viola, no more leak!!!
I've been living with this stupid leak for 5 years or more and all I needed to do was tighten a stupid nut on some threads.
I was SO tickled that it was that easy. When I've been under there before I was merely dealing with fluid changes. This time I actually went under there with a flashlight determined to not stop until I answered my questions.
Just had to get that off my chest.
