I am looking for instructions on setting up a 360 Differential and this is what is found in the factory WSM, Image Unavailable, Please Login Any other idea?
As a Jeep owner, I hear about owners replacing diff gearing/etc constantly. I can safely say that if you have never set backlash/pinion depth on a diff before, take it to a pro. This likely isn't the one you want to cut your teeth on (no pun intended). That said, I don't know what your skill level is, just a fair warning if you've never done this before.
@GogglesPisano , here is my present project ... a valve job on a 328. Image Unavailable, Please Login And this was a couple of months ago. Image Unavailable, Please Login
Fun times ahead! This is my present project. I still won't touch a diff Image Unavailable, Please Login
I also found a quick way to check the contact impression of the ring-pinion. I think this is what I need to see where I am... Image Unavailable, Please Login Image Unavailable, Please Login
You likely will not find that red lead paint anymore, but here's what is typically used for marking compound: https://www.amazon.com/ACDelco-10-5055-Gear-Marking-Compound/dp/B007Q10TES/ref=sr_1_1?dib=eyJ2IjoiMSJ9.DcY4XZhzjPXunwVXECfPuxHDrTfP6EkpUsG4XckCIaUcHAiS2jdIgvU7RibcdobRmv2upah6oGYejIrwAd4ZsymziRk69i4DQCDvNtN_EMGyPmluUShR9j4tpacQB_Jeq-l949InbxseM2QaHhRKFg5obIDJEMN5-TEdTZA3InB230huWaFOgyg_KoBdS2jh4C9d8nqfy1lprlqpWuStG36tjoJSXhDDcxehfzlN5wNSLB_xPc3TEopoeA2biULgqSvNRN9aDAnnvobvgzdZRjhnZFZnr08Sehy7-y0MpEhmZ3PGI0YrVkaz1X69DZrIJd673DyIp7buYDORkZ9yzcfAvYMelvKfexJyKZCfQZqRiRyJ656xFV5WtWVcGD-LYSsewNlPWhPU1_T9KZ6aIgmqLuf4Vk7KSpwjG-t8SQXrm-GDkdpeD1DnNPMldu41.kiraOf4GQ7XFZ1uOUeHQz8GLA4M6y3qpxe6pt0YireM&dib_tag=se&keywords=gear+marking+compound&qid=1736555233&sr=8-1
Thank you. I will order that stuff. I think what I will find is the backlash is too loose and I will need a thicker shim. I am not sure what to do about that yet if that is the case.
If you are going to get a new oil pump make sure you verify that the oil plunger moves freely in its channel before you install it. I had to go through three before I found a good one on my amc 360.
I was worried about that as well. I can’t remember what brand I went with but it was something run of the mill like crown or Dorman. Seemed good on inspection. I’ll keep an extra eye out though. Thanks for the tip!
Took my Torsen Dana 35 (2000 Ford) to a local off-road shop. They knew how to check. Image Unavailable, Please Login
I am a little confused. I spoke on the phone with a rebuilder of 360 gearboxes and his statement was the back-lash is adjusted only via the position of the pinion (in and out). The CS WSM has a picture of the pinion / ring below. It clearly shows a spacer at position 7. Would the thicker spacer here pushes the ring closer to the pinion and therefore adjust the backlash as well? Image Unavailable, Please Login
Mich Do you have the 512 TR manual ..it describes the process of how to do it using both sides spacers ..the process should be very similar
I think I can drive out the spacers and maybe ... find new ones. I am just surprised he said there is only one axis of adjustment.
Dom, I looked at the TR WSM and it does have a description of adjustment. Although the Italian-English translation is cryptic. The diagram at the end shows this. Image Unavailable, Please Login It shows two axis of shimming adjustment. I am just not sure if the two arrows mean you MUST perform both adjustments or can you do just one ?
Read the few paragraphs before where it says to start with one side and then put the shim on the other side I think that will give you an idea how to do it
On reviewing the gearbox assembly drawings, I found six different shim thickness for adjusting the ring gear backlash which tells me that there is that axis of adjustment. That means the gearbox expert I was talking to was not correct in stating there was only one adjustment (being the pinion depth adjustment). So, I am going to proceed to do a paint pattern inspection and see if I can adjust that out by the backlash shimming. I really do not have any experience in adjusting the shims for the 360 pinion, which requires total disassembly of the gear stack.
It is the ring gear that moves I believe ..by the shims on both sides of the diff ...first you adjust the pattern with one side shims and then you adjust backlash with the other side Call me if you have questions
By changing 185027 and 185047. Its not possible to correctly adjust hypoid backlash only addressing the pinion depth. Every depth change effects contact placement. Contact placement is all important.
Mitch I have a 360 gearbox manual ...call me or text me your email so you can look at the exact instructions instead of comparing with the 512tr which Brian felt was a bad idea and plain wrong .. I read the 360 manual and it wasn't exactly clear but I will send it you if you want
