1390 Oil Pipe

Post by Russ » Thu Jun 14, 2018 6:25 pm

Hi,

I've been doing the brakes on my 1390. I found this oil pipe sat in front of the diff lock inside the axle, but cant see where it should fit. I had a look on google and it looks like it is part# k915339. Which is on page K1/1 in the parts manual, but still cant figure out where it goes.

Also got 2 new oil seals for behind the brake shoes, Should the seals both be fitted facing the same way or as a pair the both springs in the centre??

Cheers
Russ

Shown in the pictures is the first pipe taking oil from an open by-pass valve to the transmission lubrication system when the hydraulic system is not lifting (90 or more per cent of the time), The transmission lubrication will be disturbed without this pipe. The conical part in the brass part of the pipe is hold in place in a conical drilling in the right hand side of the valve chest, with a bolt from the outside of the rear axle housing. Pleased see the following page off the pars catalogue. https://partstore.caseih.com/us/parts-s ... 8ar1302823 The part is ref 25 and the bolt is ref 29. The pipe is pushed into the next lube pipe, ref 31. The drawing shows these ref numbers to be one and the same part, but the pipe pictured is a separate part,

The seals both face the same way— springs faceing the diff. Fill the space between the seals with grease.
I hope you secured the diff lock pedal down before removing the right hand reduction unit.

ollek, Where are these pipes in the back end and how do I access them? Through the end of axle?

db2d,

I didn't secure the diff :( , But managed after several tries to get back in place.
