How to stop oil leak on gear box

This is so much easier with actual voice than writing lol.

Yeah, not so easy typing and explaining stuff. I didnā€™t realize you were only talking about seals that had to be installed when installing on a pump. That seal installed from the factory shouldnā€™t be leaking yet. He hasnā€™t had it that long. I guess itā€™s possible. I donā€™t think the engine is that old either but I believe itā€™s a Predator if I remember right. I would think that crank seal would go before the gear box seal.

Hey @Clean_Blue. Touch the oil with your finger and see if itā€™s engine oil. If so, take the engine back for an exchange.

The engine oil level hasnā€™t changed but I just added gear oil yesterday. It looks like the gear oil too. In the pic you can see it dripping. Also I am definitely exchanging it but not till the season is over.

To me it looks like itā€™s coming from underneath the back cover of the predator engine, these engines at the assembly line only need to fire up and run for a few seconds to be a PASS at the manufacturing plant. Also that drain plug you have if itā€™s a stainless washer you need to replace it with a copper washer stainless (what it looks like) has no crushing properties against aluminium. Clean up the engine oil and put a bit of painters tape on the rear housing of the engine youā€™ll know exactly if itā€™s leaking from there with drip marks.

Never mind I just saw the drip mark hanging.

If he has to keep adding gear oil it almost has to be that factory seal on the gear box, doesnā€™t it?

That gear box isnā€™t that old @Clean_Blue. Iā€™d call Envirospec and see what they say. You would think it would have at least a one year warranty.

Absolutely will be that seal if oil needs to be topped up, these are sealed units oil should only be replaced never topped up.

Itā€™s been leaking for a while. I just figured out where it was coming from. It took a while for gear box oil to show it was low. I will call envirospec Monday. I figured it itā€™s from engine to gear box itā€™s a gasket missing or not tight enough. I tightened it as much as I can and still leaking.

No gasket is needed between the gear box flange and engine. If oil is leaking there itā€™s either the engine crankshaft seal or the gear box crank seal. The engine crank seal is easy to replace. You just pull the pump/gearbox off. Pry the seal off of the base of the crankshaft, and slide the new one over the crankshaft and tap into place. A little lube helps. I think on the gear box crank seal youā€™d have to pull the gear box apart and disassemble to replace seal. Not sure what tools are needed but you might need a press and some pullers.

Sounds like a possible ā€œbadā€ gear box then.

I have a Predator to gear box to Udor pump. Same problem. I believe engine has this flaw. My mounting plate is always wet. I hate it but I havenā€™t done anything about it. Great engine and pump makes good money and durable but very annoying and messy. I always have oil on the truck.

I hope your wrong but you described my machine. Iā€™m gonna exchange the motor this fall and hopefully Envirospec has some advice for the gearbox.

You get it figured out @Clean_Blue ?
Sorry for your troubles man.

I purchased a Predator for a rear tine tiller I had. I think it was the tiller. Anyways, I when I was at the store I was kind of up in the air about buying it or a Duromax and casually mentioned that when I was chatting with the store manager. The store manager told me that with a Predator you can buy the extended warranty, replace it a day before it expires, purchase another extended warranty, and repeat the process. You can also mod the engine and it doesnā€™t void the warranty. You can add mods to get 32 hp out of the 22 hp engine. Thereā€™s really no need to mod it for pressure washing but sure would be fun.

I can see having a belt drive for hot just because a lot of fuel pumps are ran by belts. There really isnā€™t a need for a belt drive for cold water. Gear drives are great for truck builds due to the smaller footprint. If you haul a trailer footprint isnā€™t as big of an issue. Pros and cons to each I guess. I have a gear drive but Iā€™d be okay with a belt drive too.

This is a common issue on gear drives, they leak and the shaft sealā€¦ its not a bad repair though, I just re sealed my udor and it cost me like $40 with seal and fluidā€¦

If its an oring, its gonna get some black rtv a little tho. It works with adequate prep. On mine, since its a tiny bit a an angle, comes out the vent a bit. I may have a leak by the pump, but havent checked the bolts yet to be certain if thats it.
