Outstanding Video Series for those who are looking to do this themselves. Nice Job Andy...you've made everything very clear.

not boring at all Andy , very interesting and Sam's a sweetheart cheers both of you .

It's always a pleasure to indulge in new knowledge, and understanding on a diff cperation...... Great Video.....

thank you for the thorough explanation on the subject... also thank Sam for her technical help...Aloha Andy

Using a pull gauge is generally done with bolt on pulley [specified by maker for diameter ] a rope is wound around 2x then u use a spring weight pull gauge . Or u could use a dial type tension wrench showing in/lbs or .1Nm/1Nm

Andy, Why not turn and bore a piece of shafting, or other scrap, to the same dimensions as the shim? Next, part off several shims of varying thickness. You would have the shims you need without having to purchase them. Chevy uses a crush tube that reduces the overall length as the nut is torqued. Cheers from the States. Sincerely, Brían S. Du Bois

Why didnt I see you add the 2nd outer bearing after 32mins Andy? Otherwise a superb learning experience! You are a fantastic teacher!

Watched a guy putting together, I think it was a Toyota diff, first time I had seen this, and wondered why all the manufacturers don't do it, It has a collar on each side that is threaded, so to move the ring gear closer to or a way from the pinion gear, all he had to do was adjust the threaded collars, seems like that would save a lot of time and frustration. Just thought I'd throw that out there, enjoyed the video, first time I ran across your channel.

Are you from Hull? and why do you keep mentioning Flange while you missus is standing next to you

Hi Andy! Thanks for the awesome video. I have a question about how do you transfer the units when you are using fish scale to measure pre load. They are weight units, but pre load is force units like inch lb or foot lb.

@AndyMechanic

2 жыл бұрын

Ah, the method of measuring pre-load depends on the info provided by the Manufacturer in the service manual. Sometimes they give you load readings & provide info on where to connect the fish scale on the pinion flange (distance from centre - usually a bolt hole). Or they will give you a torque value in which case it relates to the amount of torque needed to rotate the pinion shaft using a socket on the pinion center nut. There will be a formula to convert one to another provided you know some measurements of the flange However, I don't have that formula but I'm sure a good maths degree student could advise Hope this is of some help Andy

I’m workin on my diff from my Ford ranger I had no idea about the preloads this video helped me a lot you the man Andy plus I had to watch a few times cause kept getting distracted by Sam damn she is hot I want a British girl I love the accent 👍

Correct. Each manufacturer has their own specs & that's the position Suzuki use for their 'SJ'. Diffs but you need to reference the service manual for the correct procedure otherwise the spec (load) applied is not correct. Cheers Andy

Hi Andy Are the pinion taper bearings usually "sloppy" before fitting or should the race be quite tight like a normal bearing? These are old taper bearings on an MGA diff and the play disappears when preload is app!ied.. New bearings needed? Visually they are fine..

@AndyMechanic

4 жыл бұрын

Hi Ian, thanks for the feedback. The cage does have some movement even on brand new taper Roller bearings - very different to a ball bearing race where the cage is pretty much fixed. However, the more movement on the taper Roller bearing has its an indication as to wear of the taper rollers & the cage itself. If it's very sloppy then I'd replace. Hope this helps. Cheers Andy

@19:31 you say we don't have a torque wrench ???

1.9 what Unit is it in Kg/cm or what? Please

Can someone explain what he meant when he said that tightening the nut on the yoke would not affect the preload because the pinion has a fixed collar? Wouldn't tightening the nut bring the bearings closer regardless of whether or not there are shims?

@rick343

Жыл бұрын

Put the shin or shims between the head of the pinion gear and the bearing,( I get what he is doing, but I would think you would have to be really experienced to do it that way) Just about all the videos I've seen use a crush sleeve that comes with the set, so instead of having to take it all apart, to get preload, you just keep torquing the nut until you get the correct number, it can take up to 300 or even more pounds of torque to get it there, so if you're on your driveway on jack stands be very careful.

This is one area of Diffs that always confounds me. So if you would, please explain why the shims used with a solid spacer may be needed to acquire the correct pre-load, when it seems to just be a matter of tightening the pinion nut until you achieve it!? What else might the shims be doing that I'm not seeing?

@AndyMechanic

6 жыл бұрын

+Anthony Wayne Noooooooo! You must never just tighten the pinion nut to adjust preload unless using a crushable collar. You have to select the correct shim size as no matter how tight you tighten the pinion nut you will not reduce the distance between the two taper Roller bearing races. This is a very common mistake and one that will ultimately be the demise of the diff. Hope this helps! Cheers Andy

Tightening the pinion nut will not affect the preload on the bearings - it's the shims that do that. if once pinion nut is torqued up the preload is insufficient you need to remove a shim & reassemble & re-measure preload. However, depending on how the specs are calculated by the manufacturer (it varies between brands) preload on the pinion is often measured with the crown wheel removed otherwise your reading will include the preload set on the crown wheel bearings also.

@AndyMechanic

4 жыл бұрын

Because by tightening the nut you'd just be trying to crush the steel tube & shims - this is not the answer - the tube & shims are designed to keep a set distance between the two inner bearing races. The diff is designed such that you adjust this distance by adding or removing shims. Attempting to crush the tube would only cause damage - with this design. Other manufacturers like Suzuki use a stepped tube designed to be crushed to set preload however, this tube must be replaced each time the preload is set. Hope this helps Andy

I just did one on an '05 Toyota Tacoma at the shop where I work. Just had chipped pinion bearings. Toyota dealer wanted $3000 to replace the entire differential. We bought the bearings and associated parts from the dealer for $260. Not tooting my horn here however. The point being is that the reality of why techs don't like to set up differentials is because the book flat-rate times are a joke - a sick joke at that. Honest times will induce honest interest on the part of techs to do more differential work. Get rid of the idiot number-crunchers in the auto business and professionalism will easily return.

calbrit54 I agree that book flat rates are a joke. I’m a diesel mechanic and some of the flat rates are ridiculously low. For example, to replace a wheel seal on a big rig the flat rate is a half hour. Now I could do it in that time but always take at least an hour because I like to inspect everything I pull out from the brake shoes/drums to the bearings to the torque nut and cone washers etc. Dealerships/chain shops just want the customers to get in and get out.
