Hello, my name is Tony and I work for Mini Mania and today we're going to film the video on installing the crankshaft and checking the inside. Okay. This is an A plus block. So you here by the webbing here on this side, it has the extra webbing and here is a non A plus block showing you no webbings on the sides as well on that side. Okay. That's way to identify A plus from a non eight plus motor. This specific a plus block is a 1275 engine. Okay.
Today we're going to install our main bearings installed two lower ones. Third one, my hand, this is red line assembly lube is what we use to lube the bearings. I just use a little bit of this. These are my thrust washers. These are standard thrust washers. And I'm going to grease the backside of the thrust washer. One half of them install it here like that. The other half right here. Okay. Okay. My crankshaft been re grounded a machine shop which is recommended. I dropped my crankshaft in there. It's okay. Take my center main cap, all my bearing that all my thrust washers, little grease on each side brush washer here and as well there next, I'm going to stall my two bolts which have been wire wheeled to clean the threads up. Okay. I'm going to put some fashion or lubrication from ARP. So we get the proper torque a little bit of this on the thread running down. Okay. So much smoothly.
Next, before I put my other two caps on, I'm going to put my dial indicator on here. Checked how much in play we have here. You're here with 0-0. Shut my dial indicator to zero. We see here. I saw my screwdriver here behind the cap and obviously we need oversized bearings, thrust washers here. Okay. So what I want to do 20 and we have 8000, we need to go to the next thrust washer size 3000 larger brush washers to reduce are in play in our Crankshaft, which we just checked was 8000 and hopefully we get it down to 2000s. Okay. Really? Let's put a on it trickle. Right. Sure. Over there we'll give her a little bit of prying here. Zero 2000. Perfect. Okay. You see that exactly where it should be 2000. Exactly. Okay. That's perfect. Get a little bit of lubricant on the threads. You get the proper torque check and make sure we drill, turn freely. Very nice, very nicely. I'm going to get the torque wrench and we're going to start talking down with the reground crankshaft in new bearings as you assemble it like I have it right here to check for a line board problem. You would start by torquing the center cap. 20 pounds. Let me shut my indicator 1 2nd here. 20 pounds. Okay. Torture center cap 20 pounds. Turn the crank shops, go to the next cap 20 pounds. Turn the crankshaft, everything's fine.
So far, all good. So far if there was a line board problem as I tighten each one of these caps, this will get harder and harder to turn. The crankshaft would get harder and harder to turn if I have a problem with the line board. Okay. So I want to go to my next step and talk to £40 center. It's really strong. It's really still. He's all good so far. Turns nice and free you go up and doing three steps in the last step. Going to 65 pounds in the middle again. Nice and free. Next one, next one, nice and free. Send your block is perfectly good and does not need to be line board because everything is nice and free. Okay. We're done with this section.
