E-Brake Adjustment, MSU 800 2021

Recommended Posts

Everytime I go to tractor Supply or home Depot, both Massimo Dealers, and I see anyone looking at the Massimo UTVs in front of the stores, I take the time to tell them of my "wonderful" experience with Massimo and their products and service.... They usually change their minds about buying one. BTW, all of these are  mostly assembled at the Massimo Assembly Plant in Dallas Texas.. and Cliffs right, its built from cloned and aftermarket parts from the cheapest sources they can find ....the final assembly is at the Dealer, seats, wheels/tires  ,roll bars windshield..   And yes, I am an old fart too.. I bought my first THREE WHEELED HONDA  ATC90  when I was a teenager ..when dinosaurs roamed the Earth..

The infamous Honda three wheeler. I had many a friend that got injured on one of those. Usually a shoulder injury if you're lucky. You know it's bad when the government steps in and bans them. Like the lawn darts (remember? I had some!), the original MB200 minibike (people got killed from faulty forks) beanbags, pop rocks, clackers (acrylic balls on sting) original easy bake oven with a 60 watt bulb. Yea, I'm as old as dirt. I remember getting that cymbal clapping chimp for Christmas, it had these really creepy bulging eyes. Main problem was we only had general purpose batteries back then (no alkaline) they only lasted about 30 minuets and were kinda expensive. I digress...

The old 3 wheelers were easily rolled over while turning but if you kept it going straight you were OK .. with ballooon tires they practically floated ...and thats all we had then 

I remember the dinosaurs too...

I had a chain drive pedal driven tricycle when I was a kid, that would flip easily in a turn too. Re; "floating", that's what my HS400 does on the beach., we have designated driving areas between the dunes and the beach proper that get significantly rutted up from the heavier, wider track vehicles--my little 1100 lb. UTV get two wheels in a rut and two wheels floating on the mound between the ruts; and cannot make up it's mind which way to go. 2WD is better than 4WD if I don't need the extra traction. 4WD with the front diff locked is horrible, grabbing and turning every which way, tossing the back end around.

you cant steer in 4wd.. with all wheels pulling , it just wants to go straight  not turn .. mine will actually push the turned front wheels straight forward 

My 400 will steer OK in 4WD on more firm surfaces, even a sandy road,  but on the beach in the deep, fine, soft sand we have due to beach "replenishment"¹ it wants to squirm all over the place.  Not a real problem but disconcerting and annoying when suddenly the vehicle rotates 5° to 10° by itself--it doesn't really turn, just rotates and ends up pointing in a different direction.

-------------------------------------------------
¹- Replenishment = pumping  very fine sand from the ocean floor 1/2 to 1 mile out onto the beach. It is NOT normal beach sand, more like a powder; it blows all over the place, we now have 20-30+ foot high dunes where 25 years ago there were none.  A typical Government "good intention" not thought through all the way and gone wrong in the end.

Dang man. Now that is a backstory. That is important information to me. I'm a small business owner, same company now for 34 years. I was actually considering applying to be a dealer for Massimo. My nearest authorized dealer is in Kentucky! I thought I could set the woods on fire with sales in the Metro Davidson/Nashville Area. There's 2 million people out here and no Hisun dealer.  With your added valuable info, I think I would rather maintain my reputation and especially my sanity. At any rate, I got a real laugh out loud to your: "getting tired of screwing". That's funny... I should be so lucky.

I think it wise to avoid a relationship with Massimo, they seem to care most about their interests. I don't know if Hisun is seeking vendors, but you might want to consider that. My HS400, which I bought as a Coleman UT400, seems to be quite well made; and looking at the model's history there appears to be a record of constant improvement. The engine in mine is both water and oil cooled, it also uses forced air cooling of the magneto.

I found through the EPA data that the chassis, bodywork and suspension were made by the Vietnamese  company--into which they installed the Hisun produced engine and drive train. The welds, obviously machined generated, are textbook perfect, alignment and all is spot on.

You know, I grew up in the South. I love the South. I grew up on Chevrolet/GMC, Ford and Chrysler. Pretty much in that order.  In 2010 I bought a Kia Sportage (Korean) mainly because Consumer Report gave it top ratings and it came with a 10 Year - 100,000 mile warranty. Well, fast forward to 2021. I swear, all I've put into it is 1 battery, 1 set of tires and a brake job. So...yeah

When I see that weird name, I just look at it. I've never even tried to pronounce it. I didn't see any benefit from it.

Getting back on track, how are you doing with that parking brake?

If you can post photos of what you can see, I'd love to have a look at 'em...

Yea, I kinda stalled out over here. It's been raining and turned a little too cool outside.

Here is a adjustment point. The tiny red X is the nut I will be tightening. It's too cramped in my garage right now to do it. It was a challenge to get the picture. What do ya'll think?

It looks like there's maybe 1/2" and a bit of adjustment--wonder what is supposed to keep that barrel nut on there?  Ii you get some exposed thread when you tighten it see if you can get a lock nut on the rod--looks like an M5 or M6 thread. If you can find it, the other end of the cable with the longer threaded rod would offer more adjustment--it has to be at the operating lever end...

On the new cable it looks as though the end of the threaded extension mat be upset a bit:

      I have a DesertCross 800 that doesn't want to stay in low, it pops out when I let off the gas. No problem with the other gears. What do I need to do?  Thanks.

      Going down a 20 deg hill engine is holding UTV back. Then something releases like going into Neutral and makes a loud clacking noise. Have to use brake to slow UTV down. Then once level it shifts back into gear. Have done shift extension does not pop out of gear.

      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

      I bought a tracker 88sx crew in 2023. It has a whishing noise coming from the front end. Starts out low and gets louder as speed increases. Took it back to the dealer and they said it was normal on this model. Any suggestions as to what may be causing this.
