I have a rough guess for the dimensions on this tool. I want to make my own. I'm trying to get the front bearing on my '99 Si
replaced. First I want to make the driver attachments for removing and inserting the bearings, part # 07746-0010500 (62x68mm-for pressing out) and 07747-63402010 (58x72mm-for pressing in). How thick should I make these?
Has anyone ever measured Hub Dis/assembly pilot and shaft (Part# 07JAF-SH20110, 07JAF-SH20120 respectively) For total
length and length for the two steps? Steps as in from the sections that are 25.4 mm and 22.4 mm diameter? Also any idea what length and thread pitch the tips would be?

 

I dont have the dimensions. Dont want them, dont need them. Save yourself the hassle Take the spindle to a shop that has a press and have them replace the bearing, Maybe $30 each for them to do the job. Yes you can bang the bearing out with a socket and sledge hammer. BUT when you mangle the bearing banging it into the spindle you will be replacing the bearing again in a short while. Ask me how I know. Yes you could build a tool to replace the bearings, but how often do you plan to use it? Once a year thats $5 a month to have the shop do it correctly

 

Replacing the front bearing on your '99 Si can be a bit tricky, but it sounds like you're on the right track with making your own driver attachments. In terms of thickness, I would recommend making them at least 1/4 inch thick for added durability.

As for the hub dis/assembly pilot and shaft, I unfortunately don't have the exact measurements for you, but you may be able to find them in the repair manual for your car. Additionally, you could try reaching out to a local Honda dealership or mechanic for more information.

As for the length and thread pitch of the tips, again, the repair manual or a Honda specialist may be your best bet. You could also try measuring the existing tips if you have them, and use those dimensions as a starting point.

 

I was able to do this on my other front bearing almost 3 years ago, without having long term issues. However the process was a PITA. That's why I'm looking to make things easier this time. On the left image is the hub disassembly base. What would the inner and outer diameter be to fit the spindle face? Also does anyone have the inner and outer diameters for the support base? I'm going to take my wheel off and take some measurements this weekend.

 

I'm using the shop service manual for reference, but all the dimensions aren't there so I'm reaching out on here to see if anyone's got them.

 

In terms of the inner and outer diameter for the hub disassembly base, you may need to measure your spindle face to get an accurate fit. As for the support base, taking measurements directly from your wheel should give you the most accurate dimensions.

Keep in mind that the dimensions may vary slightly depending on the specific make and model of your car, so it's always a good idea to double-check your measurements before cutting or drilling any materials.

If you're having trouble getting the exact measurements, you could also try reaching out to a local Honda specialist or dealership for more information. They may be able to provide you with more specific measurements or even point you towards pre-made tools that could make the process easier.

Good luck with the replacement, and don't hesitate to reach out if you have any further questions or concerns!

 

I think the last time I did this I found pieces of steel pipe that that were the correct diameters. Might have had a threaded coupler in there as well. Steel pipe is SUPER cheap and has more than enough wall thickness to support the loads from pressing bearings in and out. Good hardware stores will have a large selection of steel pipe and fittings and they will probably cut you off a few inches of each.

 

I’ve always just used the loaner bearing press tools from AutoZone on my own press. Well, no my buddy’s press because I gave it away to him and retained usage rights lol. Does the job and lots less crap I have to keep around for myself.

 

I've got everything apart from this one part now, The hub dissasembly base. Here's an image. Does aone have one of these kicking around to get a couple of quick measurements from?

 

Well, I have a bearing driver set and a 30ton shop press...so i've never had the no need to custom fabricate anything.

Honestly...you can just use larger impact sockets to drive these in an out. Amazon/Harbor Freight kits will get the job done no problem.

PRO TIP: Save the old bearing...you can use the old bearing to press in your new bearing. You're welcome.
