Going to try to measure the rotor clearences on the oil pump. manual says:

(Use feeler gauge)

 Standard: Less than 0.14 MM

 Service Limit: 0.3 MM

and i cant find a  0.14 mm feeler gauge.

 ?????

i think, if my math is correct it comes out to .005?  5 thou?

What machine are you working on.  I'm wondering if my low oil pressure at idle has excessive oil pump clearances.  (Joyner Renegade 1100cc)

.14mm is 0.005512"

I have a 2014 Joyner Renegade with the Chery 1100cc engine.  It appears that the oil pump is driven directly from the crankshaft.  I'm going to try a heavier weight oil (40 or 50) to see if that improves my idle oil pressure (it's at 10 psi, bare minimum).

      2018 Massimo 700 MSU. The machine started burning oil all of a sudden. One day fine-- next morning burning oil. Looking for advice. Do I pull the engine to inspect the top end or can it be done with the engine in place? Pro? Cons?
      Any and all assistance is greatly appreciated in advance.

      Decided to do an oil change on the Massimo ...drained oil, screen was very clean even tho oil wasn't.  Then went to remove old filter.. holy crap ..I tried every tool I have, could not budge it..Went to store and got one of the end cap type..fit nice and tight, put a 1/2 in drive ratchet on it..nope..not moving.  Put a 18 on breaker bar o. It. The inside of the removal tool broke off!!  Had to weld it back together. Put a pipe on the bar for more leverage.  Finally broke it loose..
      I have never seen a filter in my 55 yrs of working on engines so tight..And i was the one who put it on 2 yrs ago.  JUST HAND TIGHT!

      Just bought a brand new 760 about a month ago. I'm at 20 hours which the book says is when you need to change the break in oil. 
       
      I must be crazy, but I can't find the oil filter. I've googled a million videos...everything seems to be 2019 or lower...and/or a 550.  They all show the filter easily seen by looking in past the rear passenger tire on the engine. There is absolutely nothing there on mine. 
       
      1.there seems to be very little info if you Google a 760, or anything Massimo newer than like 2019. 
       
      2. Does anyone have a current model year 760 that can answer my riddle for me?
