Topic tags/keywords: planer question

I have a 2hp Woodtek 15” planer, model no. 855266 and need to know what type and weight of gearbox oil should be used when changing the oil. The owner’s manual does not specify what to use, and the retailer that sold the planer doesn’t readily have that info either. I recently bought the machine and know that the oil has never been changed since it was purchased new in 1998. Any help you guys can provide would be greatly appreciated.

Thanks, Phil

I don’t have that planer but I do put gear oil in the
feedworks of my planer. The stuff I use is rated
for outboard motors. The thing about gear oil is
it is real viscous so it doesn’t drip off.

My planer is on wheels, so I just roll it down to the local Jiffylube and let them figure it out.

I just replaced the gear oil in my 15” Delta planer with the heaviest gear oil I could find at the nearest auto parts store (I recall it being 90 weight). It works just fine.

Most of these planer all have more-or-less the same gearbox. Delta specs a lube with EP7 (extreme pressure) for theirs, and I wound up using a Mobil One product. But given the light service these things see in a home shop, any gear oil from the auto store will work. If you have any seepage (like mine) use a heavier oil, like 140W (actually they may all be multi weight oils by now). If not, use a lighter weight…90 weight would be fine. My point is that with the number of these in service I would bet my SS check that every gear oil made has been used successfully. So don’t sweat it too much and get whatever is handy.

Thanks to all who took the time to answer my question about the gear oil. As it turns out, the retailer’s tech support man returned to work today and told me that I should use 80 weight for best results. He also indicated that was for a cold shop, meaning anything heavier than 80 wt. might not provide the optimal lubrication needed. Thanks again guys, it was nice to hear from you again.
