Clutch/Flywheel Bolt Torque Specs

Quote from Airborne

Dave@DDMWorks and All,

Trying to install a DDM Track Clutch...

Anybody know the torque specs for the Clutch Housing and for the Flywheel?

Flywheel to the engine - 39 ft/lbs, plus 25 degrees

Pressure plate to flywheel - 22 ft/lbs

I think Dave just lifts them out by hand, being the superhero he is...

Just out of curiosity, I did look in the Polaris service manual to see what they said, which isn't much sadly...

But that's only after he has his mega dose of sprinkles for his super powers to kick in.

Any recommended engine lift points, from the PRO?

If not using the lift brackets we have, we lift by the 2 - M8 bolt holes on the exhaust side of the engine above cylinder #1 and #4 exhaust ports on that side of the engine. Then use one of the M8 bolts on the front of the engine towards the driver side just above the alternator, lastly the M8 bolt on the back of the cylinder head where the EVAP purge solenoid is mounted.

Not wanting to step on Dave's toes, but you have a couple of choices. This tool is what you need to make the job easy. You can buy a cheap one at Harbor freight for about $20, or check one of auto parts stores that have a tool loaner program. If you're unable to find either, here's an oldie but trick way to do the job. Find yourself a dowel that is the correct size (or even a couple of mm smaller.) Then try packing the hole in the bushing with grease. Carefully press the dowel inside the hole and hammer it which fores the grease to hydraulically force the old bushing out. Hope this helps until Dave sees your posts and corrects me

Never had one of those fancy gadgets but used that ol'e home remedy many times. It works like a charm, just make sure your neighbor isn't home to see you cutting that perfect size dowel off their prize shrub bush and you'll be fine!

We have stock lift mounts here that we have removed from some of the engine cores that have come in over the years. I will get some pictures on Monday and post them up for you.

Here is what one of the lift brackets looks like that can mount to the front of the cylinder head -

Here is how we typically lift an engine out though -

The cherry picker we use has 4 straps on it, 2 of them go to the M8 bolt holes on the exhaust side of the cylinder head.

One bolt goes through the M8 bolt hole on the front/driver side of the cylinder head -

The lastly we put a M6 bolt through the intake side of the cylinder head We have an oversized washer to make sure the bolt does not slide through.

We have lifted a lot of engines out that way and works like a charm.

Let me know if you have any other questions,

Dave

We have a decent amount of the black brackets like Dave was showing just laying around. If any of you are going to be removing your engine and would like a pair, feel free to shoot me an email at Kyle@zzperformance.com with your shipping address and I can send you a set at no cost while supplies last. Happy to help the community.

Looks like your brackets and hardware are out for delivery today. Let me know if you have any questions on them.

Kyle D , could you send me some of those brackets? Looks like I may be pulling another engine or two this winter. Also I would like to make some more for some people. Maybe I won’t have to keep doing this job.
