In the context of rebuilding my NV4500 I noticed a few areas of concern on my 208 as follows and am looking for some feedback as to whether it's time to rebuild it as well... 1) The front ouput flange has palpable radial free play/runout. I assume that means the output bearing and seal need replacement? 2) The mainshaft has significant fore/aft end play when decoupled from the NV4500, on the order of 1/8 to 1/4". I assume that means there is a wasted bearing or snap ring on the mainshaft? 3) Recommendations on a source for complete rebuild kits in the NW? 4) Special tools I'll need for rebuild? e.g. press, snap ring pliers, gear pullers, etc?
