Here are a few pics from this past saturday. First off is jeffs AMAZING powder coating capabilities. While jeff was putting the differential back togeather, i started tearing out the engine.
Not to bad. No scratches in the cylinder and jeff said the cam looks good.

Hey FOX thanks for the great idea on the removal tool, I followed your design but I put a pipe cap on the end of it and welded it up. Now I can use a 1 1/8 socket and a torque wrench to torque it back up when I do the re-assembly. I also made a puller for the pinion gear basically the same premise but I didn't weld them together. I take off the pinion nut remove the splined adapter put on a pipe reducer that the I.D. is just a bit larger than the O.D. of the pinion nut, thread on the pinion nut, thread on the bell reducer which takes it to 3/4 pipe thread, thread my slideonto the 3/4" reducer and alittle slap-slap and the pinion pops right out. Oh yeah hold the diff case in a vise. Thanks again for the inspiration for the tool. Only had to grind a small amount off the hex for the internal nut. The guy a the Home Depot looked at me like I had 5 heads when I told him I was building a tool. He's probably never see anyone measuring anything with a pair of vernier calipers before.
My old man loves when I make a shadetree tool, it's always good for a pat on the back. I did throw the credit your way though!

Lord of the trike
Great to hear that it worked out for you. When we got back from the hardware store I realized that I forgot about having to torque the nut back on but didn't want to go back to the store, that cap is a great addition to the tool. I was at the hardware store figuring out what I needed so I just brought the differential in and tried fitting parts to it.

Excellent work Racer!!!
As for Jim's differential. It is done. I will try and get some pictures up this weekend. I have alot going on lately with work. This weekend is snocross here in NY with the PRO's. Plus a ton of parts showed up for my Tri-z.
Next up, Jim's motor goes away for some work. Hopefully get the frame down and out to powder. Then slowly reassemble. I have a ton of small parts to powdercoat for him. Just gotta get him to buy some powder.
After all, I am doing this work for FREE

this thread has me terrified to look inside the rear end of my sx, Do they pretty much all look like that inside after 20+ years, or just ones that were beat?

Always open to trade the Sx for an X, I know, not likely, but I figured I'd put it out there.

I was terrified to look as well, when I pulled the cap off it looked as if the diff was taking a S***, literally, when I pulled out the "TURD" it was ICE! Amazingly everything is pretty nice, my leak was only from the boot and stayed contained to the diff--didn't get into the axle. The main ring gear bearings were still clean. But while I'm in there to replace the pinion seal and pinion bearings, I'm gonna do the main diff bearings and seals as well. Once again I was amazed at how clean everything was. That water has probably been there for atleast 15+ years. I just dug mine out of the barn after all that time and I haven't crossed a creek yet so I know for sure the water has been there that long, Hondas rule! And the gear lube keeps everything coated nicely. So go ahead crack her open, I dare ya, or don't.

The Pinion bearings take the serious beating. Once the boot is ripped it allows water to build up in the drive line. It passes the large pinion shaft seal and begins to destroy the bearings there. As the case with Jim's. His main bearings were in great shape. 25+ yrs old, so why not replace them.
I had the worst fears before opening this up. But hell it wasnt that bad. Its brand new now. MINTY FRESH.

Just finished up the Differential before heading to the Snocross races. Looks good. Just need to get a new diff. fluid cap from service honda.

What you're not gonna crank one out on the CNC????
It looks real sweet though, I've been BS'n with my Old Man about the PC, I think he might take the plunge for me on the gun from Eastwood, I saw a sweet double oven @ the Habitit for Humanity store by my house. The top is a convection oven and the bottom is a regular conventional oven, I could bake twice that parts with that unit! Yeah just gotta get him to spring for that as well. I wish I never had Sears take my old stove away last summer when we got our new range

True....Stainless 17-4 caps...hmmmm

Catch me if you can
Those diff caps are super thin, Honda trying to lighten stuff up!! I've broke one or two tightening them. I think I used a 200X (85) center flywheel access plug on a diff in a pinch... Seemed to be beefier too
