600 Triple(with the seperate jugs) into my 93 XLT? - Snowmobile Forum: Your #1 Snowmobile Forum

AMC · 12-21-2012, 03:33 PM

My 93 XLT is down to 94 PSI and will not start....so I want to swap this into my XLT:
rebuilt polaris motor
How reliable are these older tripples?
How easy is it to swap into my 93 XLT? Is it a drop in deal? Motor mounts? Can I use the clutch right off of my current motor? Carb Mounts?

Im putting an xlt harness on my triblock ( indy 600 aka seperate jugs) and ive ran into a couple issues. But had nothing to do with the motor. The motor is very reliable. Some people like the uniblocks in the xlts, others prefer the triblock. They are both very good engines and will last a long time left stock. It will bolt right in, carbs and exaust will fit, so will clutch. My 600 has an xlt exaust on it and it fits fine. You might have t splice a wire or 2, but other than that, bolt down/plug in. Good luck on your project! If your crankcase is good, and in not positive on this someone x2 this... But you might be able to just replace the top end from the triblock on the uni. Not sure.

I just realized thats not the motor i have. That one is a newer motor. Idk much about those. Sorry. Motor is good deal though! But for more ease you could likely find an xlt motor for a similar price... I see the motor will bolt in, and the carbs will prob. Fit. It has triple pipe exaust mounts on it but if your xlt has a 3to1 y-pipe with single exaust your y-pipe may or may not fit. Wiring i would be iffy about too. If your looking for a project i would buy it and it may be easier than expected. But if i were you i would buy a new xlt top end (jug/pistons and rings) i would guess that would cost less than 250.

I think I will go get it today, I hope it lines up in my snowmobile.
Is it a PWC motor?

That's an aggressive style motor. Have fun making stuff fit around it, steering post, motor mounts. And it's case Reed so carbs will be lower and may cause issues. Will have to make pipes for it as aggressive pipes won't fit and ultra pipes will be too big for motor and xcr 600 wedge pipes will not have enough volume.

I have been looking for one. They do not grow on trees. I want one I can pick up and not ship.

Though they do not grow on trees there are alot of parts for then on ebay. There is an abundance of them! Just get a piston kit, jug, and maybe a new head. You would be better off doing this than buying a whole new motor with worn pistons. It shouldnt be TOO much for shipping. Crankcase is alot of the weight.

I can ship a whole triple for about 65 on a greyhound bus depending on distance

Going to be a bit of work to get it to fit right in a wedge chassis. Looks like a 600 out of an Agressive chassis XCR. Best bet would be to find a wedge Ultra and get the motor mounts and carbs and wiring too. As far as I know, the 600 XCR and 680 Ultra engines are quite similar. Exhaust is another issue all together. The Ultra wedge pipe(single) may work.

Why not rebuild the engine in your sled now?

I think he should rebuild it. Would be cheaper and better. A used motor will likely not have been rebuilt anytime recently.

Well, the ad for the used engine says it is rebuilt already, and in one pic it looks like it has new pistons in it(well, the one I can see anyway).

Still going to be some messing around getting it to fit and work properly in there.

You will have a thousand dollars getting it all straightened out. Between pipes. Motor mounts, and maybe moving steering post. IMO you are wasting money and time. Just rebuild your motor. You can rebuild it for the price your going to buy that one for.

Exactly what im trying to say! x2. Yes thats a good motor but gonna be a pain in the a** to fit. Definatly go for a rebuild. Buy the rts on ebay and while setting up shipping tell the sender to use flat rate boxes because the parts are heavy and will cost a fortune to ship by weight.

Out of curiosity... Why do you want to to do a motor swap instead of replacing the top-end on your motor? If the only issue is low compression, you could re-do the top end on yours for the same or only slightly more than the cost of that rebuilt motor and you won't have to fight with any modifications to make it fit.

How much would a piston kit/jug/head cost on ebay? This is good info for him.

Polaris650freak · 12-22-2012, 11:23 PM

Who said he needs a jug and head? Maybe he can hone it and just toss new pistons and rings in. And I thought xlt are steel sleeve? so he could just bore those
