900 ace have sliders, not rollers, in the p drive.

 

1. yes C&T tools are great

2.ive had rollers seize up from not greasing them, i plan to remove them with C&T tool ( http://c-tpowersports.com/2013website/product/P%20Drive%20Quick%20Change%20Ramp%20&%20Roller%20Tool.html) every 2000 miles for inspection/cleaning/greasing. with the tool in the link you can service the rollers with clutch on sled.

3.i would say the most important tools to hace would be puller, holder, spring compressor (which is easy to make your own) and quick ramp/roller tool. you will also need a 12 point 13/16 socket to remove,install the main primary bolt.

Sliders? So like the eDrive2 they are hexagonal and slide against the flyweights? Clearly I need to get mine on the bench.

Are you able to grease the torque roller and the flyweight roller on the sled, or do you even have to do both?!

Rollers on a 900ace?

 

Rollers on a 900ace?

Let's clarify here. I have performed some parts diagram research to see what's going on; there are two sets of rollers in each pDrive, 3x flyweight rollers and 3x torque rollers.

The 850 Etec pDrive has 3x rollers against the flyweights and 3x torque rollers against the towers.

Diagram:

The 900ACE pDrive also has 3x rollers against the 3x flyweights; these have needle bearings in them and need periodic maintenance like any pDrive, from what I can gather. However, the 900ACE 3x torque rollers are non-existent, and are instead replaced by torque sliders.

Diagram:

I believe this is where the confusion is coming in. Thanks for bringing it up awful knawful, it caused me to learn something today.

I have ordered the C&T "Compress and Hold" tool as well as their grease injection tool so that I can service my 900ACE flyweight rollers right on the sled. I believe I can insert the needle tip between needle bearings on the roller and inject grease from both sides of the roller once the clutch is closed up. I will post pics when I do this.

 

Let us know how it works

 

Further to this, I got under the hood of a 2021 Expy SWT 900ACE Turbo yesterday. The Turbo has the rollers against the towers as well, different from the sliders that are on the regular 900ACE

How did you make out with this? While having suspension work done, the shop discovered one seized roller, one stiff roller and one okay roller on my 2019 Enduro 900 ACE N/A primary. They took the roller needles out, cleaned, lubed and put back together.

As they are a suspension shop, they did this as a favour, they believe I will be okay for this season, but suggest buying a new primary rather than spend the time rebuilding this one.

 

Buy a new primary vs maintaining the rollers? How bad was the seized one. There’s a possibility it could damage the ramps. I’d also check the other rollers the ones that slide on the spider. These are not ball bearing type but more like bushings

 

If these parts need to be greased at an interval similar to an engine oil change, why doesn't BRP recommend this in the owners manual and make tools to do it? Or does this apply mostly to people who use full engine torque routinely?

 

They recommend this in the service manual. Not the owner's manual, and do offer the tools to do it with but the service manual does not state the mileage or service intervals for lubricating. This grease injector is designed to thread onto a grease gun. The problem is that a full tube of isoflex nb52 grease is close to $150.00. Way more than 1 person will ever use. I suspect this was designed for dealers who would use a lot, not the single customer.
We sell our own version of these tools along with a syringe loaded with isoflex that has enough to lube all 3 rollers a couple times for $39.99.
You can buy a small tube of isoflex for $39.00 and a grease injector for $25.00. Our solution is less expensive.

 

I now do mine at 1000km's.
This year when I checked them at 1200km's one was stiff and the other two where not free but not as stiff as the first one, I was now at 2500km's on the snowmobile.

Edit, also I was averaging about 1,5l/100km more gas consumption also top speed was affected about 10-15km/h less.

 

good call mine were shot @ less than 2000km

 

A great reminder to do this at the end of the season and document it. Hopefully I can still find all the tools!

I'll do mine once a year.

 

No need to remove the clutch ,get C&T tools .

 

Great advice. Just ordered up this

 

Found this quote in another pdrive thread in the G4/G5 129” performance section. I too just ordered the C&T tool set along with their axle removal tool.

Wait for the 2023 to come out and install the 23 rollers with no grease. Apparently the 23s have a Vesbel bushing in them like old the TRA. This 23 roller will be the first thing on my preseason tune up for all my 850s.

 

Are you guys putting loctite on the axle screw when re-assembling? Has anyone needed to replace the washers, I recall someone mentioning they are fragile?

 

I put a bit of Blue Loctite on mine when I reassembled. Not sure on the washers though. Mine were good from what I could tell.

 

Thank you 6100

 

WIsh I found this thread last month. 7700km not sure if greasing would have helped. With the CT lube kit do you still have to take the roller or axle out?

wow, never seen that happen! to clean./grease the rollers to remove the torx screw then tap the right end of the pin so it comes out of the left end of the roller.

where the heck did the rest of that roller go??

 

Well, the tools from C&T are great. But as I was warned by the main pdrive thread over in another section of the forums, I thought I was likely in trouble after more than 12, 000 km’s with no service. In my defence, I had never heard of a requirement to grease needle bearings in a clutch before. I found that thread on it after I was already at just over 9,000 km’s. I left it until end of season so I’m at over 12,000 km’s now. Went to grease rollers, first was easy, thought, oh good, my fear was unfounded, maybe I don’t drive as hard as some other guys on the forum. Second fell apart as soon as I removed the axle, plus the axle was grooved. Bad axle on the third as well. I just ordered all new rollers, axles, thrust washers and screws. I will keep up on the maintenance from now on. I just wish I had known about the requirement sooner, I would have done it before it got to this point.

 

And I can still see the video how BRP said no Maintenance on the Pdrive Clutch 🤣🤣🤣 which was like 2017 if my memory serves me right>>>>>I had a 2017 renegade 850 when they first came out as a spring order

 

And yet no one has posted a video of this routine maintenance. Please for the love of God... We aren't all born with silver wrenches in our hands...I can do things but I'd like to see what it looks like first. Who will be the first on the interwebs to post a video of the vaunted pdrive clutch roller greasing?! Cheers!

 

Theres plenty on youtube buddy

 

I've googled and searched youtube and yet to find a video of greasing the bearings

 

ok ok they dont grease the rollers but they show you how to remove them.....i think you can figure the rest out without bein harsh....its pretty str8tforward....

 

Heads up on closely inspecting your needle bearings when you remove the roller and before you inject the grease. Those cages can be slightly cracked and still retain the needles, but failure is imminent. This one has just 2800kms on it and the other two were good but I looked closely and sure enough, junk. Gave it a little jiggle and the cage separated spewing needles.

Going to replace all three pins and rollers for peace of mind.

BTW the C&T tool makes this a one beer job. Thanks Chris !!

 

No compressing needed to remove the rollers. Just an axle removal tool and a T 25 torx.

 

Thanks. Just ordered the tool and grease from you!

 

The axle / pin removal tool is a must. The syringe and adapter make application of the Isoflex into the roller a breeze. I’m doing all the sleds in our group with a PDrive, even the new sleds coming in.

Does everyone recommend greasing a brand new sled? I was planning on ordering and using the C&T tool after the first season.
