Oil leaking from generator

Most likely at the output shaft of the motor. If you are handy, you might be able to replace the crankshaft seal yourself, but this will probably require you to seperate the generator from the motor, and remove the cover holding the seal. If the leak is small, it may be best to just keep adding oil. If you have to take it to be repaired, it may be more expensive than the unit is worth.

I don't think there is any way to tighten or repair leak other then by replacing grommet. sorry I'm not much help but coleman powermate is no longer in business and I have had no sucess in finding a source for parts for you.Thank you and good luck.

As with most briggs engines if you are operating in an area where the temp is below 20 degrees...use 5w-20 or 30. Between 0 to 100 use 10w-30. above that 10w-40 can be used but be sure to check the oil and temp often.

Check spark, is plug wet? use sae 30 oil for summer use

is there an oilprotection on the gen. disconnect the cable and try again

Even though Powermate generators are discontinued they still have a website with owners manuals at www.powermate.com.

If it comes with a Briggs & Stratton 3.5 HP series 93400 engine, then the oil capacity is 20 fl oz (0.59 L). Hope this helps!

google it! use the specific search terms, Coleman power pulse 1850 - it worked for me!

I bought a replacement recoil starter for my 1850 at Pats small engine parts. The part number for a 3.5 B & S is 499706. If you look on the heat shield on the side of the motor there is the engine model and s/n. Hope this helps.
