Bought a Yamaha Terrapro

[The kid]

I dug up a picture of a Pro-Hauler and now that I think about it. The odd rear rim and brake drum I believe is from one. I have mismatched rear rims i'm going to replace and the rim sure looks like the one in the picture.

Dave, I've seen pictures of the ProHauler but never seen one for sale anywhere.

I have never seen one either. Never a TerraPro, either. Rare birds.

The ProHauler was a 2WD machine with a locking differential. Rear diffs on ATVs are almost as rare as
PTOs. The YFU1W ProHauler was one of only 3 models I have found that had one.

Here's some pictures of my second while I have it stripped down.

The Pro-Hauler probably had an identical differential.

The YFU1W ProHauler was one of only 3 models I have found that had one.

I meant to say 4 models had a diff, including the current Polaris 550 X2 Turf and the 86-04 Kawasaki Bayou KLF300A.

The TerraPro seems to have only one rear brake, as does the ProHauler. That means rear brakes won't do
much in unlocked mode. Hmmm.

It has four wheel drum brakes. The two front are cabled off the handlebar brake. The rear are both hydraulic and mechanical hand emergency brake. I'm looking for a rear drum and rear rim now to replace a mismatch someone put on.

Interesting. The parts list shows only one, as with the ProHauler. Maybe the PH also has 2,
but they are the same, so the diagram shows only one. Since the parts are not
available from any dealer, the online parts list does not even show the quantities needed.

Here's another rarity for the TerraPro: it has a manual tranny with hand clutch. Can you think
of any other utility quad with manual tranny?

Hello guys! I just came into possession of a Terrapro and have been looking for people who know something about them. Looks like I found the place. I just got it home yesterday and started tearing into it today. I drained the fuel (looked like red wine), cleaned the air box (packed full of rat nesting), and pressure washed the mess out of it. It has been sitting for about a year or two. Put new fuel in and after about 5 minutes of tweaking it fired up! It only runs mainly while I have the choke on and sometimes when I turn the choke off. Figure I will run a good bit of carb cleaner through it and blow it out. If that doesn't work I will see about having the carb pulled and cleaned unless anyone has other suggestions. Oh, I forgot to mention it was given to me because the owner didn't want to mess with it. I started pressure washing the years of grime off of it and it is somewhat blue again but I will need decals. Kid, where did you order yours from?

Your pilot jet is clogged. It is very hard to remove from the hole it is down in. You need a long slender flat blade screw driver to get it out. It must fit perfectly or you'll strip the head. I had to buy one off of a snap on truck to get the right one. Being long, you can put a bit of torque on it and it's hard to explain but the torsion of the long 12" skinny shaft helps remove the pilot jet. Next, get yourself a small wire bristle brush and pluck 1 wire with needle nose. Use this to poke thru the pilot jet's hole. You need to put on safety glasses and spray carb cleaner with the straw tube into the small hole where the pilot came out. One of the holes supplies gas thru some microscopic holes that are in the intake hole just where the butterfly flap seals when closed. These are your idle circuit holes. Today's gas with ethanol is horrible. Put some marine stabil in your gas and do not let it stay for long in the carb for extended periods. Also get yourself a small inline fuel filter and install it. Good luck.

Kyle, do you think running some Seafoam through it first might help or do you think I just need to go straight for the jet? Where exactly should I look for the pilot jet? I am a bit mechanically inclined but not real good with smaller engines.

Does anyone have an electronic copy of an owners manual or repair manual they could share for the Terrapro?

 

[Kyle_in_Tex]

No snake oil will work. You have to physically poke something thru the tiny hole.
Buy a new needle and seat assembly while your at it.

Hey Kid, do you have a link to the photos you are posting? For some reason the attachments aren't pulling up on my end. Also, do you know where I can find an owners manual and a repair manual for the Terrapro?

Tried to view the attached pics but can't open them. Says that it's an invalid attachment. I'm using Windows vista and Firefox. Anyone else have this problem?

Kid, I have a Yamaha terrapro with the bush hog, rc42 and the belt just broke, do you have the measurements for a Kevlar belt?, (
The decals. I cut myself and may make another set. There is three layers of colored vinyl to create them. kelvar belt and take precise measurements of it. Belt pitch, width and exact outer length. There is a margin of error on the length probably an inch or less.) Also I no longer have the schematic for the belt installation, do you have a picture you can send?, john


The paint is nothing more than Rustoleum enamel that I custom mixed. I bought a quart of the closest color and added white till I got the shade desired. I also added a enamel hardener from TSC to speed paint drying time. Enamel takes forever to dry. If you add some hardener it changes dry to the touch in about three hours. It also adds a higher luster to the paint. You are right on the ocean blue. My next project is the RC42 then move to the TC38.

I'm currently got my second Terrapro stripped down. Found a bad rear emergency brake line and a mismatched brake drum. One wheel has the wrong rim. Speedometer cable was broke. This is the nastiest bike I've ever worked on. I took the PTO off and polished the housing. Waiting on parts right now. Guess I'll start refinishing the plastic till those parts come in.[/QUOTE]

If I get a chance I will photocopy a couple pages of of the owners manual that described the exact procedure on installing the belt in a RC42. I don't have the measurements of a belt but tension and proper installation is key to longevity of the belt. Kelvar type preferred but cheaper ones will last quite some time. The belt If I remember correctly is a bit tricky to install. Over tightening the belt is easy to do.
