Axle nut - Honda Foreman 400

Recommended Posts

Hey all.  New member here who is attempting to revive a 97 Honda Foreman 400.  This evening's task will be dealing with the rear brakes, but I was hoping that someone could tell me what size socket I'll need to get the axle nut off?  My impact set only goes to 22, and I don't think that's going to do it.  

Thanks in advance, and thanks for the great resource that this forum is.  It's been a huge help so far.  The 4-wheeler is running for the first time in 3 or 4 years, and that's quite an accomplishment for someone who isn't very mechanically-inclined!

@Fishfiles once posted the metric/SAE for large sizes that match.

i used a 3/4 inch breaker and socket set i bought at estate sale.

 

spray it down with deep creep. I would heat the nut slightly with a plumbers torch. Just to get it hot and spray it. Dont ruin the dust seal on the hub

Interesting.  I assumed it'd be metric, since every other bolt & nut on it that I've encountered so far has been.  Thanks for the info guys

One of those situations were the metic nut has an equivalent std size.

 

I have Harbor Freight metric impact sockets, and one of them fits those rear axle nuts.  I can look when I get home from work.  Heading out early today as I had to bring the kids into the office with me.

Hi -- that would be a 30 MM socket


Thank you!  Was hoping to swing by NAPA on the way home and not have to caliper it to find out.

Well I'll be.  I learned something new.

I think the last time I did one, it was 30mm or you can use 1-3/16 inch socket- its the same size either way

1 13/16, I have the wrench, couldn't remember if it was 5/8 or 13/16.

Think you did a typo , it is not  1 13/16 ----  it's 1 3/16 = 30MM    ----   the 300s and 420 straight axles  have nuts on the axle which are 1 5/8 " /41MM  , this 450 rear end doesn't have those nuts as there are tubes over the axles

So mine, a 1997 TRX400, is a 41mm or 1 5/8 socket?

30mm it was. Opened it up and found my problem. Pads were separated. Inside of the drum doesn't look too bad, other than being full of brake dust. What cleaning do yall recommend other than to spray it down with brake cleaner and hit it with a wire brush?

I would take the time to remove the brake cam lever , buff , polish and grease the shaft as they will get sticky and or frozen up

That's about the cleanest rear brake panel I've ever seen LOL.

 

Do what Fish said with the cam pin, and slap some new pads on it.

😄 And here I was thinking it was nasty!  Then again, considering that's the first I've seen, I didn't have much to compare it to.  I'll definitely be removing the shaft to clean it up.  The rotor inside doesn't look bad at all though, so I think I can probably get by with just wiping it down.

Next time I'm in my shop I'll take pics of what I usually see here. 

 

You'll be very grateful that yours is as clean as it is.
