Need engine for 2008 Prowler 650

My oil pump apparently bit it, and took out both the top and bottom end on mine. i don't really have $2800 for a new engine. Any help would be appreciated...Thanks!

Welcome to the forum, sorry about your motor! Do you have the skills needed to rebuild yours? It would require a new crank and rod, camshaft and rocker arms, cylinder honed, and possibly a new piston. Looking at 1,000.00 dollars in parts. If not, you may find a good used one at www.powersportsnation.com, good people to deal with, and I've never heard any bad things about them. Used Prowler motors are rare!

Would it be a good investment for us with older prowlers just to replace our oil pump with a new one? A new one isnt that expensive. If so, then a couple of folllow up questions:
- is it a big job to change it? Any special tools needed?
- if you change it, is it anything else you should change at the same time?

A replacement oil pump gear for sure on the older Prowlers (pre 2008), and you are right on also installing a new oil pump. I did mine when I first heard about the gear issue, and I also replaced the hardened pin that drives the gear. They are also pretty cheap!

That is correct on the parts. # 3 is such a small part, I've never heard of one breaking, but for the little it cost, why not? Snap ring that secures the pump is very small, make sure it is seated when reinstalling! I use heavy weight oil on mine, and that is one drawback on using heavy oils, puts more strain on the drive gears! I've seen 80+ psi oil pressure on start up! Good maintenance on Prowlers makes them last, and is by far cheaper than paying later! LOL

The link would not open for me. So I can't see what it is pointing to. The common failure on these Prowlers was the oil pump "DRIVEN" gear. Maybe your '08 has the modern one, but I'm not sure. But the part# you want for the driven gear is (Gear, Driven 0812-083). The old style gear teeth were known to sheer off and destroy engines.

Replacing the pump and driven gear is easy, however, having an impact wrench makes the job a lot easier with pulling off your clutches and wet clutch. I would recommend replacing your inner case gasket when you do the job. The outer clutch cover gasket can be re-used if you are careful with it. But wouldn't hurt to replace it as well.

#1 is the pump it self and #3 is just a small pin.

I thought it was the other way around, that the pump went bad, and then the teeth on the driven went bad becouse of that?

Think The replacement will be easy, was in the same place couple of month ago when I had to replace a seal on my primery after a oil leak in the clutch house. Got a good impact wrench.

Oil pump is pretty durable, but Gyrotor design makes it impossible to check the clearance on the rotor. I changed mine, and kept the one I removed as a spare. The gear change was also cheap insurance, mine showed little wear, but I changed it anyway! I hate oil starved motors!

Speaking from experience it's the teeth on the gear that fails, here's what mine looked like on my '07 650.
