Jet planer leaking oil

[Dennis McDonaugh]

I was doing my post-weekend cleaning last night and noticed my jet planer is leaking oil--looks like the gear box gasket is leaking. I've only had the planer a year, but it spent 5-6 years in a cabinet shop and received heavy use. I took a quick look at it and it looks like I'll have to take the feed roller and cutter sprockets off to split the gear box case. Has anyone ever done that? I'm hoping I can simply remove the sprockets and screws holding the two halves of the gear box together and split the case. Don't want to get into removing gears and such.

Which model planer? You may be able to find a manual for it here (http://www.wmhtoolgroup.com/JETGeneral/Manuals.html).

If you have the 15" planer, you may not be able to find the manual online. (I didn't see it...) However, you should be able to split the gearbox by removing the chain, a single sprocket, the knob and 5 hex screws. You should not need to remove any gears. You'll probably need to replace an oil seal (JWP15H-333) when you replace the gasket (JWP15H-336). I would recommend you call them for assistance and a manual at 800-538-8665.

Thanks for the information Kevin, sounds like I can handle it with no problem. I have a manual, but it just covers adjustments and parts diagram--no disassembly

Dennis, have you tried just tightening the bolts that hold the case halves together. I had a leak on my Griz. and tightening fixed it-2 yrs ago, and still tight. :)

My 15" Griz did the same thing about a year ago, 6 months after I got it. Not a spot, after tightening the bolts.

Good Luck.

I'll give that a try first, I didn't even take the cover off last night, just loosened it up and took a quick peek underneath. I couldn't lift it very far because of the depth adjust wheel.

Like the others above, my 15" Delta was leaking......a quick tightening of the bolts and not a drop has escaped in over a year. Guess they just don't torque 'em real good from the factory.

....and it was still under warranty....even had a tech guy come out and fix it.......all on Deltas dime ! She's A-ok now.

What I recall him doing was replacing the *O* rings and adding more oil to the chamber.

Now that I read this, I wonder if all he had to do was tighten some nuts?

I have the Jet 15" planner (JWP-15CS) and it's been leaking oil almost since day one. I figured after 15+ years it's time to fix the leak. I have the gearbox removed and it appears there is no shift knob oil ring/seal (JWP15H-333). I realize this is an old post but I am hoping that you/someone can offer their suggestion on how to insert the oil seal into the grooved cut-out in the knob shaft casing.

Thanks in advance for any help.

It appears this is the same as a Grizzly 1021Z planer. If so they show the o-ring and part number for it. It also lists the o-ring size and type so you might be able to source it locally.

Remove the cover and catch as much oil as possible. Apply liquid gasket as needed. Replace cover. Fill with gear oil.

My 20" powermatic has done this from day one. The dealer basically said, "deal with it". Oddly enough, this is the only power tool ive purchased new. The leak is so slight that I never see it drip, but like you, the evidence is at the base of the machine on the right side. Let me know if you end up replacing the gasket and if its a quick process, or total PITA. You might inspire me to take mine apart.
