Why would you start in the middle of the assembly?

Yes! Thank you for this information. Helped me out.

Where did you find bearing to rebuild with? Thanks

Just trying to finish left one on our Boomer 50. It was pretty well destroyed. I found what was left of the shims, I would say there were only 2 washers, and I got a pretty good guess at matching the thickness. I left it on the bench last night and was reading the service manual. It said to put the 4 different shims in. Do you remember how many were in yours. I have a gear stop and an indicator to check the backlash, I just don't want to put it in and out any more than necessary. Good informative video. Thanks

Where did you get your service manual?

My LS xr4150H developed a leak underside of left, front wheel hub. Will only turn to left. Will not turn right or just barely at very low speed. Loosing fluid, steady squirt gun. Anyone with good news? Bad news ok. Thanks

Very nice. Thank you! If you have all the part numbers including seals it is helpful. I am doing this right now and found you can take the top nut off below the grease zerk and the whole shaft including the blade will drop right out leaving the bearings in the deck to be removed separately. I have my deck up about 3 feet on homemade horses so I can access both sides of the deck to get the parts out and replace them. It wouldn’t be a whole lot more work to remove the last three nuts and remove the spindle housing from the deck, but the deck holds the housing so I can pound off the races and seals.

Did you pulled that seal apart ? Or left it together with the blue clear tape it’s come with?

Where did you get the pdf repair manual? I have a XR4145 that needs new bearings. Need to get the torque requirements? Thanks

buenas tardes líder dónde puedo conseguir el reemplazo de mi amortiguador desde República Dominicana gracias

did you hear a clicking noise before it went

Do you have part #s?

The factory manual suggests to add grease after 15 minutes of mowing. I found the preload on these to be pretty tight and the spindles got pretty hot right at first. I would mow, then add grease, continue to mow and add. I did this several times to ensure there was sufficient lube as they broke in. Once broken in, I found this mower to be an unstoppable beast in taller grass compared to my mulching deck.

What are the bearing and seal part numbers that you used?

Any idea on the cost for the new hub as well as the hub housing? Mine just grenaded as well but galled the heck out of the spindle and housing. I'm doubtful the seals will seat correctly with the damage.

Much quicker and safer way is to put something in between the lever and the grip and then to use an offset spanner to bend the lever back. Super simple and super quick.

just dropped my klx im freaking out but i’m i bit more calm now seeing this thankyou!

So people don't curl those on purpose??

Why not show something about shat seal, is there a lip the seal seats against in the bore?

Good

What was it reading before you that??

Glad you kept the heat away from the grip so it didn't get wrecked. :-)

I have the same pump and the inside bearing came off with much difficulty too. I placed some wood under the pulley for supporting the recessed ribs, and pressed it off. I took a piece out of the inner holes with a puller before pressing it off. Thanks for the video as it helped me save the cost of a pump. I found the repair kit on E-Bay. The shaft seals are also available too, on Etsy if the bearings are still good. Available from Bulgaria for $10

What tool do you use to remove the lock click off when there only a little gap?

Use a gear puller and pull the pulley off then remove the snap ring don’t listen to this guy the gear pulled will not break you pulley

Should the pulley come off with simply using an impact hammer? Or is there something else that needs to be done to get the pulley off? I am bracing the pulley on two wood blocks and trying to drive the shaft (and body) down with an impact hammer.

was hoping for part 2 but no more! why!? Thanks for posting this!

How did u fix? Having same issue but my plates wont compress either

Hi pal iv got same bike had topend done still wouldn't kick did this work I'm sick of bumping the thing

wht is the measurement eye too eye 15"? anyone herd you can use an 85 shock on an 83???

Just look it up in the service manuel, this seems to be the way to do it. i'm definitly trying this on my (hard to start rmz-450) COMPRESSION PRESSURE CHECK << RMZ-450 value, check your service manual The compression pressure reading of a cylinder is a good indicator of its internal condition. The decision to replace the cylinder is often based on the results of a compression test. COMPRESSION PRESSURE SPECIFICATION **(Automatic decomp. actuated)** Standard 430 - 720 kPa(4.3 - 7.2 kgf/cm Low compression pressure can indicate any of the following conditions: * Excessively worn cylinder walls * Worn piston or piston rings * Piston rings stuck in grooves * Poor valve seating * Ruptured or otherwise defective cylinder head gasket * Decomp. trouble * Valve clearance out of adjustment. COMPRESSION TEST PROCEDURENOTE: * Before testing the engine for compression pressure, makesure that the cylinder head nuts are tightened to the specifiedtorque values and the valves are properly adjusted. * Warm up the engine before testing. Remove the related parts and test the compression pressure inthe following manner: • Remove the seat. (!5-2) • Remove the fuel tank. (!5-2) • Remove the spark plug. (!2-7) • Install the compression gauge and adaptor in the spark plughole. Make sure that the connection is tight. • Keep the throttle grip in the fully opened position. • Kick energetically the kick starter lever about 5 times to turnthe engine. • Record the maximum gauge reading as the cylinder compres-sion." 09915-64512: Compression gauge set 09913-10750: Adaptor

try kicking a yz 250 2 stroke with 265 psi

lucky u got your pulley off - mine shattered, had to drill it out.. VERY odd design, the pulley is actually cast around a 1" hex nut made from same soft material.. I think getting the c clip off as u described then putting a bearing holder under the pully right against the centers with torch heat works best.. fyi bearing numbers are skf 6202-1rs

that isnt xr200r shock.. they dont include nitro bottle

What is the torque spec for the nut that holds the Piston assembly?

Men you should assembly the gaz tank with the shock and put gaz tank upper. Full the shock and the tank completely with suspension fluid and move the shock slowly until all bubble go out. Let rest the shock some hours and insert the nitrogen chamber in the tank pushing all the excessive oil by the nitrogen chamber out just enough to put the clips inside. Then full the nitrogen...

How did the 3wt oil work for you?Thankyou

Does every bike have decompression cause my 2005 Honda crf250r I don’t hunk has it but I’m going to do the valves and see if it helps

Did you have any issues getting the damper rod out? I cant seem to get it to come out. Both circlips are out, but it feels/sounds like its getting stuck on something.

FYI, they usually have an o-ring in that valley on the shaft between the bearing housing and the impeller housing.

S Trum, did you make a video of how to reassemble the pump. It would have been nice if you would have posted the video of the work you did on it. I want to rebuild mine, but I thing I will be way over my head.

Great video, thanks for the info. Say, you'd make a great dental tech !!!!

Awesome man!!! Thanks a lot! Now I can sleep through the night. What weight shock oil did you use??

Thanks for the vid brother, this is exactly what I was looking for! I'm getting a bunch of oil spew out of my crankcase breather hose and I suspect it is blowby from the piston rings after I just installed a big bore kit. Apparently some of the kits come with too fine of a finish on the nikasil so the rings don't seal correctly but I'm gonna hopefully test the before and after once I deglaze the cylinder then put new rings and attempt to break in once more. It happens to be the same bike as here by chance except an 04. What would be a terrible PSI, below like 150? Thanks again

Stock compression is 12.6:1 or around 185 psi. 170 is still ok.

What is considered a good number when your doing a compression test like this? I got the same bike as you and im suspecting a leak somewhere, rings or gaskets.
