I like the way you work D-Ray. Love them 300 fourtrax video's. Keep em coming...

Nice work sir, I watched the whole series and I am impressed with your work and the well done video

Totally blown away at how you show every detailed part of the job!!! Man this has really helped me get mine put together!!

Thanks DRay!!!! We found an old 300 in trade of my sons 125 dirt bike, I didn’t realize what a great trade we got! You can’t kill 300s! But my teenager sure killed the rear end! Waiting on rebuild parts to get in then will be doing this to ours. I don’t have a hearing press but I have a hydraulic jack so was thinking of welding a frame around it for a make shift press??? Thanks for these videos dude! Saved my life! And 200 bucks lol

This guys is awesome and knows what he's doing. Great video!

Love these videos. all of these videos are good references when I'm doing a rebuild

Nice job D-Ray. You do things properly.

Grea job man! love how nice and clean you do your work

First class you number one GI

Great video series! You have a great way of taking a complicated job and making it doable.

I needed to see this. Thanks

Thanks D-Ray this helps me a lot rebuilding mine

grammatical precision is evident

Nice clean job thanks for the insight!!

Made it look easy D-Ray. I bet that press comes in handy. Yeah I would of either lost a few parts or forgot how to put that dang thing back together....lol. Nice Job.

we need more D-Ray videos where they at

a 3/4 in sockets set work great for pressing stuff in or out with graduated sizes to fit almost any seal or bearing over the 7/8 socket size

Great Job.

You make it look so easy ;)

Just as good as new :-D

nice work

Just like a factory tutorial. Probably better.

As you were pouring that gear oil I could actually smell it.. Strange!!!!

Ever thought about just using grease on the pinon bearing or would the grease not be good for the gear oil?

Remember the bearing on the end of the opinion could be so bad that it changes the size of the end of the opinion or we get what I’m saying I just ran into this the end of the pinion that goes on the bearing with the circlet has about a quarter of an inch enough in it so I had to buy a new pinion and rain gear

hey ? for you, how do you know what size specialty tool is needed for removal of the pinion nut? I have a 2001 trx250ex some say 60mm and others say64mm

Have you ever packed those bearings before you think that would help with keep water out of these things or do they have a updated bearing kit?

When did you install the seal from the driveshaft into rear diff? Just wondering if it needed to be pressed?

Hey D-Ray Smith, I have a final drive with all the teeth chewed off (PO, this is my first drive powered atv, did not check, because it drove fine, but when i drive it for a bit at home i noticed a grinding noise, opened it up, had like tar and metal shaving in it.) I got replacement shims and stuff. Currently I am trying to get the shimming correct on the pinion and drive gear/disk but having massive problems. I can not get the shimming within what the repair manual says. I did get it correct one time, but then the free play between the teeth was not in tolerance. How important is it to get the shimming correct on these things? Can i just say F*** it and put the best fit in and use it without worrying about damaging anything? (because you just like throw a shim on it and call it a day) Also, how important is that circlip @ 1:11 that goes on that pinion bearing ? My differential did not have it (i assume this dif was taken apart before. I can not find a replacement online. the bearing still stays in there regardless, but i am just curious if its gonna cause problems later. I know that was a lot, sorry but your expertise can save me ALOT of work, money and frustration. Cheers!

I have a Polaris Sportsman 450.. Wondering if it has a similar setup ? Actually quite a bit of work going on there.. I wonder what the dealer would charge for a lengthy job like this?

What seal or bearing do I need to get to stop oil leaking into break shoes on a Honda trx 250 tm 2010 is it the seal in the gear box that needs replaced and if so do you know the part number? Thanks

Help PLEASE!!! I ordered the kit. Got it apart and ended up needing a new gear set. While awaiting gears the work bench was cleaned by someone else and the spacer shims for ring gear were thrown in trash apparently. There are 20 different options for thickness. Where do you think I should start? In your experience is there a regular OE combination I should order first to start with?

Whats the trick to getting that internal C clip in on the needle bearing for the pinion apart from your way.I tried your way :) could not get the clip in the thick part on the cable tie was the problem

Do the 2 shims together equal a certain spec like 3mm or 3.25mm or 3.50mm?

If you could I need info on 02 Honda 450 foreman trax lok on front diff tear down and seal kit thanks.

Just checking no adding any grease from inside?

great series hope one day ull do some videos on polaris sportsmans :)

How did you get the needle bearing out that the pinion goes into? I saw you installing the new bearing with the pull strap wrapped around it, but I never saw how the old one was removed...

since when did Mcdonald's start cooking up atv parts rofl

How do you know what size washer to put between pinion and large bearing that goes on the pinion gear?

Be nice you were to talk about how tight the maxel bowl tap to be the big nuts that are jammed together

Put your bearings in the freezer they will drop right in

So this not really a diff is it? It is just a pinion and a ring gear.. Where are the differential gears? This diff doesnt make sense to me.
