Thanks guys. I do (with some contorting!) have access from above as the panel is positioned over the engine block with the fan itself being "tucked under". The problem that I have encountered is that the fan blades are very closely spaced and getting my hand in between them to reach the hub is a challenge! But, I CAN get my left hand in there (barely!), along with a box end wrench, but I only have enough space to use the fingers on my left hand to pull the wrench, and I just can't develop enough torque to free the bolts! Of course all of this is done by feel, not by sight! Suggestions? If I should eventually get it apart, what other parts are necessary to switch over to the greaseable bearing? I have maintained modern farm equipment my entire life so am not a novice at removal and repair at any level. Also humble enough to know that asking others for ideas is a smart thing to do - so input gladly accepted! :-) Thanks! John

I have a 2004 National RV 37' Tropi-Cal with the 3126E CAT engine and 56,000 miles. I have read that the non-greaseable engine fan bearing is prone to failure anytime now and I would like to preemptively replace it. I've been looking and scratching my head as to how best to tackle this project. I am hoping to avoid removing the radiator and intercooler. I have read that owners of other makes of coaches have cut access panels into the fan shroud and perhaps coach floor. Do any Tropi-Cal owners have some advise? Thanks! John
