Changing the trans-diff fluid in my 135 and the multipower filter looks like it's covered with dirt. Is is possible or even feasible to remove the filter from the pump through the PTO cover or does the lift cover need to be removed? The filter is the bolted version. The bottom bolt is behind the pickup tube and seems like it would not be an easy job. Has it been done by anyone? I am considering using a tank type garden sprayer and using diesel in it to wash it down while in the case. There is some sludge in the bottom of the case that would benefit from the diesel also and I hope I can spray off the filter enough to avoid removing the top cover. Thanks for any advice in advance.
