A little aid I have discovered for installing stator covers or any cover really (engine cases)is using a couple pieces of 6mm threaded rod about 6-8 inches long and threading them into a couple of bolt holes by hand , this eliminates any alignment or gasket issues as you slide them on. Long bolts with the heads cut off work even better because of their smooth shank , you can make some with various lengths to suite any job .

@@FourwheelerDoctor I just bought a 2020 brute with a motor was told is good started but only went up to about 15MPH. After watching your videos I saw that the heads and cams are bad, with that said what year cams can i use is it 2015 and up? it gets better,.. Flywheel chewed up my stator and there are pieces of magnets all in the motor.,, What do you think would be the cause of that and what should I look for? on top of that it also has a spun bearing. I ordered new rods and the yellow snap in bearing like you use in this video. Im just about to split the case. So far I have ordered new rings, Stator, flywheel, new heads used 2015s,... Do I need sent these to a shop to be worked?, 3 chains, complete engine gaskets and seals kit and inner rotor pump it was split. with Said,.. What should I look for from here? Thanks for your time and the most educational videos on the tube!!!!

When I pulled the transmission shafts out everything came out pretty easy. The bearing on the secondary clutch shaft came out of the case with the shaft. Now that I'm reassembling it, the bearing and shaft will not go back into the case. Any clue why it's so much more difficult to install than to pull out? I've tried to hammer the shaft back in, but it barely goes, and it doesn't want to stay square with the case, and it also feels more difficult to spin the shaft in the bearing. I'm thinking I need to pull the bearing off the shaft first and install it in the case, then drive the shaft into the bearing to prevent damaging the bearing, but was wondering if you had any better ideas first.

I have a 09 650 sra im needing to know what hose hooks to the front intake? the back one is the vaccum for the fuel pump. Thanks for any help.

Thank you for making your videos. I am in the reassembly phase of my 2012 Kawasaki Teryx 750 FI and completely opened up the engine case, replaced the crank(spun bearing) with a new Kawasaki crank, rods, bearings, totally washed/cleaned the cases, I put the new crank in using the freeze heat method, installed the trans, same method. When I put the cases back together it took quite a but of effort to get the left side case onto the crank. Once torqued down the crank will not move. I once again split them but am unsure what to do......HELP! I feel as though the left crank bushing(original) still looked good but the tolerance between that and the new crand are way too tight. Thoughts and thank you.

More than likely your crank is not pressed all the way into the right crank bearing. Not sure if you can put it back into the press at this point or I have taken a handle of the sledgehammer and hit the end of the crank with the handle to move it ever so slightly and make it spin freely.
