Front Right Tire Camber Adjustment


Recommended Posts

If you pay any attention to your UT400, you have probably noticed that the right front wheel tips in at the top a LOT.  The left fronts seem to be about right from what I've seen.  I look at them all when I'm at different stores just to see if they're all that way, and yes, they all seem to be that way.

There "should" be adjustments on either the ball joints or the inner pivot points, but these are solid, not way to adjust them.

I have the UT400 up on my 2-post lift and the right spindle seems to be around 3-deg tipped in at the top and the left spindle is about straight or maybe half a degree tipped in.  This is at full suspension drop, not ride height.  I took the shocks off and rotated the spindles from bottom travel to full max up travel, way more than the shocks will allow.  The higher the spindle lift, the more tip in there is on both spindles.  This is true because of the unequal upper and lower A-arms.  It's just the nature of of the dual A-arms and them being unequal in length.

I took the inner pivot 8mm bolts out and inserted a lot smaller 1/4" bolts and pushed the lower A-arm inward and the angle on the spindle decreased.  I then took the top inner bolts out and did the same thing, but pulled out instead.  This got the spindle equal to angle of camber on the left side.  I used the offset in the holes to see how much I need to go on the lower alone.  I was also concerned about bottoming out the axle assembly because the spindle centerline will not be a bit closer to the front diff.  But as it all turned out, it was not close to bottoming out.

I cut about 1/4" out of the two 1" A-arm tubes as they were welded to the lower ball joint mount casting.  I tack welded them back together and trial fit it all together.  That seemed to be about right.  I took it all back apart and welded it up solid.  Now it all looks to match the left side quite well.

Also want to use this in our yard and the stock tires are NOT turf friendly, especially with the solid "spool" rear differential.  I found these on Amazon, 25x12-12" and 25x8-12" hard pack race tires as they're called.  They're 6-ply and tubeless.  The initial probably I had was that the size rating was not even close to the actual size.  They said, install and then recheck the diameters and I did.  They did get larger, but the rears are more than 1" smaller in diameter than the side wall stamping.  Instead of 25", they're 23.75" tall.  What I DON'T WANT are shorter tires.  I had already purchased the used wheels at 12" to match the original factory diameter, but in hindsight I would now opt for 14" wheels with 4x110mm bolt pattern and would have been able to find a tire in the 27" diameter range a lot easier and cheaper.  Live and learn they say.

Here are some pictures of before and after.

Wow, that looks good, Dan. You did a great job. I noticed today that my tires squat out on the bottom too. and are toe out. I don't have the skills to take care of the camber as you did, but hopefully I can adjust the toe, so I can have some sanity to this.

I also, for the first time, noticed my steering wheel is way out. Looks like I'm constantly turning right. I need to find information on straightening that out also. Now that I've noticed it, it's driving me crazy 😂

This is the steering wheel when I'm going straight. I never noticed this before and this is the kind of thing I notice first.

Don't worry too much about the steering wheel alignment, for now that is. 

Do your toe in adjustment and while the outer tie rod end jam nuts are loose, you can take the six steering wheel cover off with a 4mm Allen wrench. Loosen the nut holding the steering wheel on and unthread it so it's flush with the end of the steering shaft. Use your knees or have someone lift up hard on the steering wheel while you hammer the nut/shaft to break it loose. I use two hammers. One ball peen hammer on the end of the nut /shaft and use the second one to hit the first one. A couple good whacks and the steering wheel will come loose. Then unthread the nut and pull off the steering wheel and realign the shaft splines and the steering wheel to make it straight again. 

You may have to readjust your tie rods a bit to get true center on the steering wheel. I adjusted my toe IN to about 3/16" on each side. 

Also, you'll have to release the two inner tie rod boot cover outer clamps so the tie rods can turn without winding up the rubber boots. Don't forget to reclamp the boots. 

I said a lot of words, but it's really quite simple. 

Good luck, Dan

Haven't been around and able to read this, but thank you for taking the time to explain what to do. I will look this over and approach the problem as per your recommendations.

      I've seen a number of requests for the location of all the grease points on these machines, and there is no definitive list in the manual. This covers the UT400, but other Coleman/Hisun models should be similar.
      Tools:
      First to grease your machine you need a grease gun and some NLGI#2 grease. You will find it helpful to buy a needle attachment as pictured here, due to poor clearance on some of the U-joints. The rest of the zerks use the standard attachment.
       
      Technique:
      Wipe any dirt/grease off the zerk before greasing to prevent pushing gunk inside and causing excess wear.
      Push the grease gun on the zerk at a straight angle and give it a few pumps. You will hear an oozing noise or sea grease coming out from the outside of the greased area when you've put enough grease in, a few pumps should be plenty.
      If it's just oozing around the zerk you either don't have a good seat with the gun, or the zerk may be rusted and the check ball frozen. Try seating it again and regrease.
      Wipe up any excess grease when youre done to prevent making a mess.
      Greasepoints:



      Rear A-Arms are greasable with the wheels on from the rear, I took the picture with the wheel off for easier visibility

       
      That's it. All other Hisuns should be substantially similar.

      Spent today at a Honda dealership looking at their 520 side by side, then on the way home past our Lowes noticed they had several new UTVs on site, so we U-turned and ducked in there. We were impressed that all that came for $9,999 metal whole length skid plate, nice sized bed, roof, windshield, side mirrors, winch, upgrade looking tires… all of which would have added thousands of dollars to an already expensive Honda 520. Now Honda does have a great reputation from my trusted UTV experienced buddy, so it has that going for it.

      Hello to anyone who reads this. I am Jon and I own J&M Outdoor Power, a very small, small engine repair shop. I was approached by Coleman about 6 months ago to become one of their Warranty Centers.
      I recently received 3 different UT400's and a UT500 all with similar issues. These units range from 2 months to 2 years old. Customers state that the unit(s) was/were running fine, then heard a pop and a loss of power, two would no longer start. The two that would run would not achieve normal operating speed (around 20mph I would say) without redlining the RPMs. I quickly found that the Valve lash on each unit had become too large on some(both intake and exhaust) and too tight on one(just intake). 
      After setting the gaps to .005(I found multiple different people suggesting bigger and smaller gaps, but no definitive Coleman Spec number yet) every unit starts, runs, and achieves top speed without issue.
      I don't know how many others have come across these issues, and I wanted to get something out on the web for others in the same predicament. 
      Please let me know if you have had similar issues.
      Edit: I realize that this will not be a fix all solution for this issue, as the oil level and condition should be verified before moving to the valves. Many times improper oil conditions will cause valve lash to change. These units all have good oil and proper oil changes.

      Since I've seen some questions on this I took some pictures and will provide instructions on a valve adjustment for the UT400. This should be the same for the 550's and other various Coleman/Hisun single cylinder models with the cylinder slanted aft.
      I have seen several people ask of it is really necessary, and read several reports of valves being out of adjustment from the factory. My valves were .004" intake, and .010" exhaust with about 5 hrs on the machine.  I've seen different numbers thrown around for factory spec, but I decided to go with 0.005".
      This is called valve lash. What is is is a gap between the rocker arm and the valve then the camshaft isnt opening the valve. Why does it matter? If it's too large the valve doesn't open all the way, if it's too small the valve dosent close. This can cause valve damage (overheating) as well as loss of engine power (burned fuel is going out exhaust rather than pushing the piston dow).
      Tools required : 5MM Allen wrench, 10MM box wrench, needle nose pliers, flat feeler gauge set, rags
      First you need to remove the fan cover on the passenger side. There is a cooling vent hose on the back side, remove the hose clamp and slide it off. From there there are 4x 10mm bolts holding the cover. The forward ones can be accessed from under the seat.
      Next remove the spark plug from the drivers side. Carefully wiggle the spark plug wire off. Grip it as low as possible and give it a little twisting motion as you pull it off to help free it. Its a tight fit for a socket, but there is a sheet metal wrench in the toolkit that fits it. Unscrew the plug and set it aside. This allows you to spin the motor over freely with no compression to fight. When you reassemble this is a good opportunity to switch to an NGK iridium plug for better performance/less fouling DR8EIX)
      Next you need to remove the intake and exhaust valve covers. The intake us the forward one. There are 3x 5MM Allen screws to remove. The Exhaust is the rear with 2x 5MM Allen bolts. Both covers have O-Rings instead of gaskets and are reusable. When you remove the rear be careful and use your rags as there will be oil that drips out.
      Next up we need to spin the motor over to top dead center. Grab each rocker arm and give em a little wiggle up and down. Spin the engine over by grabbing the fan with your other hand. Spin the engine over until both rockers have some wiggle and are loose.

      Once both rockers are loose slide the feeler gauge in like shown above. Try different feelers as needed to determine your starting spec. You should feel some drag but still be able to move the feeler without too much force.
      If you need to adjust, use the 10MM wrench to slightly loosen the locknut, then with the correct feeler gauge in place, tighten the top square nut while wiggling the feeler in and out. Once you have it right you need to tighten the 10mm lock nut without moving the square head bolt. Once the lock nut is tight recheck the clearance.
      That's it, button everything back up and make sure you have it all reassembled before running it again.
      If you find this helpful give me a thumbs up or comment. If you have any questions or need more help let me know. If there's interest maybe I'll do some more of these
