TIMING CHAIN Praire 700 4X4 REPLACEMENT

Recommended Posts

Hello, I'm new in this forum and I'm from Catalonia, so I apologize if my English is not so good.

I have a Kawasaki Praire 700 4x4 form 2004 and I wear it to the mechanic one week ago because I had engine start problems. Those problems are resolved now, but the mechanic told me that few weeks ago, a man from my city who had a Bruteforce 750, had very high problems with the engine because one timig chain came out from their chain tensor.

I try to get information about the chain replacement, but here, in Spain, there are very few models of Kawasaki ATV, and nobody knows so much about them. We told that one possibility is to remove the chain tensor and show how much has been stretched, and if it is in the end of his travel it would mean that the chain must be replaced, but the mechanic is afraid about it because he did the same operation with the case which I had explained before and it ended with bad failure. So he told me that if we remove the chain tensor he want to change all the timig chains and tensors from the both cylinder.

We loock for the material price which we need to replace it and it will cost more or less 500€ (525$), and here we have to add the labor cost: 200€ (210$).

Now, the ATV (from 2004) takes 750 hours, and I don't use it very much, only two or three days a month with a 80km trip, and in summer months I don't use it.

So I ask if somebody could help and advise me if I should change all the engine chains, or if I could drive it more hours with no needing to be worried.

Thank you very much, and sorry for my English.

Welcome to QUADCRAZY! If the timing chain is stretched you may hear some noise but it never hurts to to take the cover off and inspect for slack. Not sure how hard it is to do. If you replace a chain, always replace the tensioner. I would look at the manual and see what the recommended replacement interval is.

                        Thank you for your answer Ajmboy.

 

Nowadays I don't hear any noise from the timing chain, but as I have known these case about one boy from my village who has broken the engine, I am a little bit frightened.

The mechanic said me that he doesn't want to remove the tensioner to show it, because if the chain locks god we will not change anything (it is what he did with my neighbor's ATV which has broken the engine) and if after that success the same he will have to assume all the consequences.

If somebody can help me I will be very grateful

This being a twin cylinder engine it's not all that complicated to time up.  Each cylinder has a chain and a cam shaft at the top of each cylinder.  Remove the side cover to get at the lower part of the chain where i runs around

the crankshaft sprocket (gear) and look for the marks.  Then remove the cover on top of each cylinder and check the marks on the cam shaft.  Turn the engine over until the intake valve opens and closes on each cylinder and when

the piston comes top dead center block it so it doesn't move then line up the T mark on the top gear and then do the same for the other cylinder.  Both pistons will then be timed when the pistons come to the top.  Check both tensioners at the same time and make sure there isn't any slack in either of the two chains.  If there is then you may need to invest into buying new parts.  Without knowing anything else in regards to your problem it's hard

to help you out.  A service manual is what you need before doing anything so i attached one for you belonging to a Brute Force 750, the timing procedures are the same as for the 700.

 

good luck

    • what is a good 4wheeler with a manual transmission?

      Hello there, i am wanting to know, what would be a good 4 wheeler with a manual transmission?  Either a real manual with a clutch, or a semi automatic transmission. Either 2 or 4WD will do.  What i do want is one that has a rack at each end and can pull a small trailer.   So what are your suggestions? I am open to most any brand though Linhai is the only one from China i would buy.        So far it looks like Arctic Cat is overwhelmingly what fits what i'm looking for, but like i said, i'm open to almost any make. If there is any rivalry over brands count me out, i like them all.   What i do want is one that will last through farm use, hauling feed sacks and so forth.

    • 1997 Kawasaki Bayou 300 2x4 (klf300b) Runs Bad

      Hey I have a 97 bayou 300 2x4 (klf300b) that i bought for 1000 last June and sunk another 1000 into it already.  When i went to look at it, the seller had warmed it up before hand (he was riding it when I got there).  it ran good so i bought it and took it home that evening... next morning it wouldn't hardly start.  I discovered the carb was clogged, there was chunks of rust in the fuel valve, the choke lever was missing and other things.  I have since cleaned the carb and replaced the fuel valve and gas lines and cleaned out the gas tank and cap.   Enough background on it, the problem is this:  It floods if i push it past half throttle in 4th and 5th gear even going downhill and shifting correctly.  It also has to idle and warm up when you first start it which is really annoying now that its cold...  It also smokes blue smoke for about 15 seconds when started cold-  does not smoke at all once warm but the exhaust still smells like burnt metal.  A friend told me that it didn't have enough compression.  I also found out that the valves are a common cause for low compression on Kawasakis..  I have never adjusted valves before-  the most I've ever got into a engine was a head gasket on a riding mower so I'm new to this.  My goal is to get this bike running and starting cold like a top-  should i tear down and rebuild the top end?  What should i try first?  I tore the carb apart and rebuilt it and fiddled with the air screw and nothing changed.  I also ordered a compression test kit that should be coming in soon. Ive also considered just selling it for like $500 and taking the hit-  Id rather not sink too much more into this machine..  lol

    • 1997 Kawasaki Bayou 300 4x4 - Service Manual

      Hey guy and gals I'm a new-be here an just need a lot of help So please forgive me if I'm doing this wrong! First off My name is Rob and thanks for having me here you'll. I just acquired a 1997 farm hand bayou 300 4x4 that is in need of a lot of TLC I traded the fella even up for and old Yamaha street bike I had about $850 into that ran good and did not leak or burn oil but still needed many minor things like brake worked seat and so on So about the Bayou-it runs starts right up and all but is missing some things like the front and rear racks clutch lever and small plastic cover in front of handle bars My issue is that the fella said he put new piston & rings in it about a week ago and checked out the clutches like I said it runs and I know I should have taken more time to check everything out so when I got it home I found out there was no air breather and I can't see how one would have even fit on there the way the carb is so close to the inner frame rail under the seat on it and it started leaking oil pretty bad from the clutch cover (it was clean oil though light in color) The quad is not bad lookin and I can weld up some racks for it but I really need a service manual for this old work horse!!!!! I have no issue following directions other than sometimes giving my own creative touches LOL ANY HELP WOULD BE SO MUCH APPRECIATED THANK YOU AND HAVE A BLESSED DAY ROB
