Cat 992C Cold Start.  I love watching these from my comfy house verses being out there coaxing frozen diesel engines back to life. 3 am show ups to get the fleet running by 6. When I was driving long haul in the 1970s, the semi used had a detent lever that would not allow for cylinder compression until released. Excellent for cold starts by letting crank get up to speed, oil flowing. On releasing, the diesel started,  began running quite well.   That machine looks tight for its age I love the old controls in those machines it's what I learned on I always feel right at home in those cabs great piece of equipment there awesome cold start to.  This is a case where a bit of starting fluid would make a huge difference. All that grey exhaust smoke means that unburned fuel is soaking piston tops and especially exhaust valve stems. Many of these engines have been damaged by exhaust valves sticking in their guides after the unburned fuel on valve stems turned into varnish, when the engine warmed up. Use block and oil pan heaters, when starting in cold conditions, use enough starting fluid to make sure all cylinders are firing.  It's a big motor people. Relax, it's called routine cold starting. Sometimes I have to crank my truck with a 3406 CAT a couple times before it wants to come to life. She has almost a million miles on her here in PA and our winters get pretty nasty. No problems if you're an experienced operator. Nice videos man.  this is a one of the best wheel loader CAT made it for really heavy working!! I remember on year 1991 I operate a model like that and the engine working around 3 month's NO STOP day and night 24/7!! just 3times per day making a break for put fuel grease check levels and full throttle I can prove this equipment is a KING no one can resist like this!! we talked about on year 1991!! I don't know today.  Cranking on a starter like that is perfectly fine, done it many of times, cold weather and diesels don't mix my truck has 178 thousand miles and I crank on the starter like this to get it started sometimes, haven't replaced the starter yet
