Farmall Super M Engine Knock Ep.16: Sr. Answers Viewer Comments & New Cam Bearing Tools Finished

[@bobuk5722]

Hi Senior. My late Dad once told me that the man who never made a mistake never made anything. I've always remembered those words of kindness and wisdom. Hopefully replacement bearings were not too expensive. I'd assumed that the tool had bounced to and fro on the bearing, but now I'm sure you're right, leaving out that load spreading washer resulted in a bell mouth effect. It's sometimes fairly easy if you have the instructions - but not always - and us engineers are famous for ignoring them at any rate. It's always obvious what went wrong afterwards, not so easy at the time. Oh and I know my Dad would have agreed with you - pulling is kinder. Thanks for sharing. BobUK.

[@ron827]

It was GREAT to see you acknowledge the suggestions and admitting errors is a sign of a true gentleman.

[@bobpaterson1845]

Top man that can admit his mistakes 💪 we are never too old to learn and you are teaching us something with every video thank you 👍👍

[@paszkors]

I like this approach better. Thank you Senior for recapping the issue and coming up with plan b. I’m sure it will go smooth. You’re a fine teacher.

[@ambiguoussoul1246]

I like your idea. 15 years ago at Cummins we were still using the bar and hammer method. We now use a foot controlled hydraulic ram that pushes the bushings using dies and a long bar that has step graduations. Similar to what you are doing but on a manufacturing scale. I really enjoy you and Squatch253's videos.

[@marpip01]

I did almost the identical thing for the bearing drivers with .020" clearance but i made a driver pretty well the same as the otc or snap on one that you have and had no problem putting the bushings in other that aligning the oil holes . They drove in quite nicely - was wishing that i had the driver set you had .But if you got a lathe you can make these quite easily .

[@dougkubash8673]

I worked in a automotive machine shop in the late 70s and we had the machined bushings for the bearings and for alignment. Ours used a slide hammer but I like your idea better pulling them in with the threaded rod. If you were patient and didn't get hammering too hard our set up worked good. Some engines it seemed like the bearings just installed easier. You guys definitely do some quality work

[@duanequam7709]

Looks good. Loved your story about Sachs snowmobile engines. I worked for Scorpion for 12 years and we used a lot of them in the early days. Good video.

[@tpniefer]

Great video Senior. We all learn from our mistakes; not our successes. As one of the other guys commented, a man that never made a mistake is a man that never did anything. Much respect to you, Sir. Stay warm in that below zero weather. You guys have been taking a pounding this winter if the weather reports are accurate. Cheers.

[@stevewesley8187]

The theory behind the larger hammer relates to the increased mass moving the bearing shell more easily , where repeated blows with a smaller hammer tends to swedge the edge of the bearing in contact with the driver . Really enjoy your videos and the range of subjects covered .

[@chucktodd7329]

Additionally there is a frictional difference. Static Friction is higher than Dynamic Friction. So once you get the bearing moving, it moves easier. Repeated strikes have to overcome the Static Friction each blow. One large strike only applies One Static Friction impulse. The pressing action Senior is now using will always need to apply the Static Friction impulse. as long as the Static Fiction force is less than the Plastic Deformation force of the bearing will survive.

[@KennyKizzleRustyNutzRanch]

I use the same method when installing bushings in the front pedestal. Threaded rod, washers, nuts... Works just fine! Nice job, Sr.

[@jerrytalley337]

Great video. My only caution to you would be to make sure that the shouldered bearing install plug has enough clearence on the o d so that when you pull the bearing in it does not crush down and lock onto the install tool. Your cam bearings have probably a three to four thousands press into the block which will result in the i d of the bearing reducing that much when installed. The tool you bought at the swap meet is a good tool and works very well but yes there is a little bit of learining curve.

[@volvoguy76]

Thanks for these great videos. I enjoy the time and explanations you give. Most of the words out of your mouth are good and educational! :)

[@alanharney5278]

A simple but elegant solution, Senior. Those are usually the best ones. Thanks for the video.

[@mikeembrey9176]

You did a good job on making puller pulling is always better than driving bushings, have a great week

[@jenniferwhitewolf3784]

Awsome look at how the tool actually works. My dad was a complete tool junkie and an engineer. He was a great teacher.. would take the time to study, and then show, just like this. Old school ways, learn, learn from mistakes, and teach/share. Squatch family mechanical methods are right on !

[@evankibbe590]

😊😊😊😊👍👍👍👍👍 Sr I do a lot of dismantling of aluminum castings with seized beings and your right if you heat the castings the bearings will fall out. It's much easier than a hammer.

[@seniorelectrician6831]

A true leader! Always out front not afraid to admit a misstep and correcting that mistep as well

[@stanpatterson5033]

Interesting that you should mention the old Rotax snowmobile engines. My first "sled" was a '74 Olympic 400 with the old 399 twin. No decompression on those puppies. Made for a real workout at 40 below, when the Tillotson carbs didn't want to co-operate. The first few pulls of that stone-cold engine were a real test to both your arms, and the pull-cord, too. That old thing held together well. Well, the engine itself did... one night when it was about -35, I was out on the "speedway" (the local river that was frozen over) when the drive sprocket at the front of the track came all apart. I can't remember if the axle had broken or just the axle retainer on one side, but whatever it was, the ride came to a rather abrupt stop in the middle of the river. The motor was still working, but couldn't drive the assembly. So, I sat there in the dark and the cold until my buddy came back looking for me. It's quite the experience sitting with the engine off, listening to the ambient sounds at 10 or 11 pm. You can hear other snowmobiles in the distance, the wind, and the eerie sounds of the ice below you cracking and groaning as the cold penetrates down into it and it bears your weight. You hear the sounds radiate along the ice, it's both scary and neat at the same time. Ended up towing that old machine home on a toboggan, and sold it cheap to a guy who had some welding skills. He welded the damage back together, and got another season or two out of that thing before he wrapped it around a tree at pretty much top speed and that was the end of her. My subsequent snow machines all had Mikuni carbs, I would never again fight with a Tillotson carb, thank you very much.

[@ericcorse]

I had a question about alignment but you were several steps ahead of me. I'm with you hammering on those bearings doesn't seem like a good plan.

[@harrypotter4309]

We made a tool very similar to that which you made, for installing cam' bearings into a Ford 400 V8. It worked really well, just got to make different mandrels now for Ford 302 and 460.

[@MrBuck295]

Keep in mind when you freeze or just cool your bearing you will reduce the inside diameter as well as the outside diameter , so your adapter might not fit in the bearing and trying to freeze it with the adapter already installed will cause problems as well

[@bcbloc02]

The comments can be a valuable resource. I love reading the ones on my channel. :-)

[@roygunter3244]

I worked at a plant where we would replace bearings on the electric motors used around the plant from a few horsepower up to 500 HP. We had several specialty bearing heaters, one of the fellows needed to put a bearing in a small electric motor at home and needed to heat a sealed ball bearing to do it. He took a metal funnel and turned it up over a small flame and placed the bearing on the funnel, being tapered it stopped on what became the stack of the heater. It worked well expanding the bearing without baking out the oil and since he had the metal funnel and the heat source it didn't cost him any thing. We occasionally would drive a bearing on with a pipe against the inner race without heating it on small electric motors but like you I don't like hitting a bearing, large, small or otherwise.

[@regsparkes6507]

Well now, it seems that we, ( and I include myself in this of course ) are never to old to learn something. This is a good video, inasmuch as you've shown what was done incorrectly,..you now have shown what is correct to do. Next video, we'll see this put in action. Thank you Senior, this is much appreciated.

[@kevinoscarson2941]

Look for a hollow ram enerpac cylinder. You could slide that rod through it, and pump up the cylinder it would pull thoose bearing right in.

[@aserta]

Whilst the tool is indeed a good one, and it does as advertised when used to their instructions. Yeah, beating bearings is not in my wheel house. Something wrong about that, and whenever circumstance forces me to do it, i'm always hesitant. Bearing materials do well in wear situations, it's their purpose, but sudden shocks can have/lead to adverse effects. There's deformation imperceptible to the human eye, i've heard that in some types of bearings of the more brassy nature, you can get micro-fractures in the material and that instantly fails the bearing, yet you'll never see them, so on and so forth. Either way, good thing people were on the go and knew the right way to use it, and that they put it forth. Sharing, is after all, caring. :)

[@ShainAndrews]

Good review. I seldom see a straight stick of all thread. Granted I order 5' 3/4" sticks so it is easy to see. Doubt a slight bow would cause an issue in your application, but good for a guy to keep in mind.

[@shitindawoodsbear5956]

Sunnen press lube my friend. If you use it once youll never install a bearing/bushing dry ever again. I have an old OTC cam bearing installer similar to that . I use a tiny bit of blue loctite between the threaded rod and extensions as well as the male "expander" piece on the end. The reason i do that is so the "nut" on the end loosens when the rod is turned and the expander doesnt get stuck in the bearing. Also the nut that expands the 4 piece collar , i barely tighten just till its snug in the bearing. To prevent the tin layer on the bearing from getting all marred up, i coat the expansion collar with thick grease. I may have used improper nomenclature in this rant, but if youve ever put bearings in , you know what Im trying to convey. Im curious too....is this the block thats getting dry liners pressed in? If so why are you putting cam bearings in first? If this isnt that engine forget i mentioned it. Thank you for the video.

[@joefalmo5528]

Try changing your O-rings to a smaller cross-section diameter the one that my dad had that I inherited many years ago had much smaller diameter O-rings and it seem to work OK even though I never did care for most of the stuff I do are larger engines so they have to be pulled in I’ve never screwed up a bearing that I’ve pulled in like you most of the time I just make a custom set one for a guide one for a mandrel are use a piece of acme screw thread that’s hardened and it works great

[@chrisskelhorn5727]

I'm not a fan of clouting things, especially when we're talking about bearings! :-O Another good video Senior! :-)

[@darrenblattner2508]

Now your cookin with dry wood, I'm not into hammers for engine assembly either, disassembly is different.

[@garyfeltus9801]

That's a very informative video. Thanks for sharing.

[@willpost5675]

Can’t wait to see this thing breathe fire again. Tell us where you got the parts from Senior?

[@joelmollenkopf3767]

Excellent

[@pwaletzko]

Do enjoy some quality hammering.

[@ambiguoussoul1246]

I said hydraulic but meant pneumatic. We use shop air.

[@bertjetolberg103]

Hammer them in is probably good but your way is definitely better

[@Mudmowerdiesel]

Fantastic video

[@robertmailhos8159]

Well you live & learn hope you get all.that done in do.time sir👍😄😀😃😊😁

[@bulwinkle]

The old fashioned swing press is never a good idea when installing bearings.

[@michaelspinello3607]

Maybe you could put the Cam bushings in the freezer before installing?

[@hank5655]

you should of taken it down to a machinist and had it lined honed
