Old guy that lives down the road is having a problem with his box side by side. It'll start and run for about five to ten minutes then bogs down and dies. It will not start up till it cools down and then it will start fine and do it again. Gauge shows not overheating and the oil and antifreeze is topped off. Any suggestions on what it can be? Just trying to help him out.

Sound like a fuel starvation issue.  The next time is dies, immediately open the fuel tank cap and see it the engine restarts.  If it does, you might have a plugged or kinked fuel tank vent line.  That vent line allows filtered air into the tank to replace the fuel that was burned. If that doesn't do it, then someone smarter than I will have to help.  A friend had that problem with his small outboard motor.

      As with any forum you join, there is a requirement for an obligatory introduction... and that seems fair. How else do you get that first post in there without jumping in with some stupid question right out of nowhere?

      Hi. I'm Space Ghost. Well, not really, but that was my call sign on my last deployment before an IED made me non-deployable, and I an now retired/disabled, and living on my wonderful VA disability. I did almost 28 years in total between the Army, Army Reserve, and National Guard. 1 deployment with the Reserve (Desert Storm) and 3 with the Guard (1 pre, and 2 post 9/11)

      Married (going on 30 years) one of each. (both out of the nest)
       
      Just picked up my first side by side a couple days ago. A 2020 Can-Am Defender HD10 DPS 6x6. 

       
      It's in pretty good shape, but as you can probably tell, it's sitting a bit high. Former owner put a lifting collar on the shocks. 

       
      The good = almost 17" of ground clearance. (30" tires) 
      The bad = incredibly steep driveline angles, and a pretty stiff ride. 
       
      They will be coming off. 
       
      Other than that... clean as a pin and appears very well maintained. 
       
      Looking forward to seeing what this forum can bring, and hoping I can bring something in return.

      I'm working on a 2005 Cub Cadet side by side and I'm trying to remove the front two axles.  I have a slide hammer puller on the inner joint and with all my strength they will not budge.   Anyone have the same issues and is there something I'm missing or a trick of some sort to pull these out?   Any suggestions please and thank you.

      I'm working with a 2015 MSU-500.  Basic symptoms are it cranks well, but will not fire.  It has spark, and it has fuel spraying out of the injector (and spraying starting fluid into the throttle body and plug hole makes no difference).  It has compression.  I bought it not running, and no other information was available.  It has 775 miles on it and 127 hours.  It looks to be in very good shape.   Previous owner replaced fuel pump, ECU, coil, plug, and the fuse/relay box that mounts on the firewall, then gave up.
      My questions relate to cam/valve timing, considering the symptoms and diagnostics so far.  My thinking was the woodruff key sheared off and the crank spun, making it out of time.  My question is, by the pictures attached does anyone have an opinion as to the cam/valve timing being correct?  In the crankshaft picture you can see a timing mark visible.  In the camshaft picture I have arrows directed towards what I think are timing marks (which appear to be exactly 180 degrees from one another).  However, the long arrow in what appears to be bolt configuration in line with the piston/rod line.  Here is a puzzling note... in the position you see in the pictures... I have valve lash on both the intake and exhaust.  I think it's at TDC, given the visible crank timing mark and valve lash on both valves. 
      Any thoughts ?  Does this appear to be in proper valve time ?  Have I missed anything simple ?  Thanks in advance for your input.

      Bit of background. First the machine would take for ever to start. So I adjusted the valve shims into spec and made sure the timing is correct. Starts perfectly now. 
       
      now it fluctuates on idle. Bogs down, Revs up, repeat. I noticed the fuel pressure drops from 60psi to 20psi while that happens. It also bogs down at the lower end of each gear, higher rpm seems to be fine. Seems to struggle under load. In neutral it revs up perfectly. 
       
      brand new fuel pump, fuel filter, gas. I noticed on the fuel pressure regulator there’s that vacuum nipple, it’s not attached to anything and I’m not sure where it would go. Possibly the problem? 
       
      Another issue is the tip off the end of the exhaust is broken off, sensor is still attached and connected. Could that cause these issues? 
       
      my next plan was to look into the pressure regulator and voltage to fuel pump while driving. Is there anything I’m missing or any ideas you guys have? 
       
      thanks!
