Step 7: How to Install Polaris 350 400L Xplorer Crankshaft Gear and Counterbalance Shaft Timing

[@osbornebay944]

Super. Steady and clear instructions, it is a pleasure to watch your detailed video vs those shaky and poorly lighted ones.....

[@donutdan1508]

Doing research for our next project. Thanks for sharing your knowledge. Appreciate it! ✌️ 🍩

[@BrapStuff]

If you have a press, it helps tremendously. I do these engines much more easily and quickly with a press.

[@Dukk1078]

One of the best if not the best video I've seen on this. Thanks man.

[@BrapStuff]

No problem! Let me know if you have any questions. Ride safe!

[@osbornebay944]

Thank you, l see all the balance gear/shaft line up marks off your video.

[@tankabbot22]

Awesome videos! I'm getting ready to rebuild my 99 Scrambler 400. You know you stuff!!!!

[@BrapStuff]

Thank you man! If you have questions don't wait to ask. Brap on!

Getting ready to do the same thing to my 99 scrambler 400 also

What’s torque spec on slotted nut

[@chrisb5345]

How difficult is it to get the collars out during tear down?

[@omarsalinas5629]

I finally got my jug back from the machine shop and started rebuilding motor. Are both collars the same? On the meg side the collar I used went in kind smooth all the way in. Didn't have to tap it much.

[@steveb5434]

I have an incredibly loud whining noise when running now that I rebuilt it. It also is hard to turn over by hand with the spark plug out. Maybe over-torqued my slotted nut?

[@osbornebay944]

What to look for when install balancer gear to balance shaft? thanks.

[@BrapStuff]

Align the timing marks (indent)

[@osbornebay944]

@@BrapStuff Thanks, got it.

[@kimandmatt9900]

Love the videos. Hope you can help me. I pulled the gear off my 1993 350l 2x4 water pump. And didn't mark location of punch. Now have no idea were it goes. Engine completely apart and am trying to figure out the position of crank rotation compared to water pump. Any help would be greatly appreciated

[@BrapStuff]

There are timing marks on the gears.

[@kimandmatt9900]

Yes my problem is I removed the gear to work on the shaft and did not mark the location of punch mark of gear to shaft. Now have no idea were to press gear back on to have counterbalance in proper location.

[@BrapStuff]

The counterbalance and mating gear have timing marks as well.

[@407pelon]

how much oil do these gears take and where's the drain for it please help

[@arthurcaldwell1234]

Great videos thanks you do a great job

[@BrapStuff]

I am thrilled you found it useful! Brap on!!

[@johnoyler6028]

What is the tork specs

[@ediwaldosanchez7268]

What's the torque spec on the slotted nut?

[@osbornebay944]

29-45

[@doctorfeinstone6524]

How do you prevent bending the water pump shaft? I keep hearing they're very easy to bend

[@BrapStuff]

See my other video. Pull the shaft out by pulling on the gear....you don't need to touch the shaft at all.

[@derekharms7996]

Thanks, this helps a lot

[@BrapStuff]

Awesome, glad it helps!

[@omarsalinas5629]

Do you use any gasket maker on the big gasket? Like how you did on the water pump gasket? I am still waiting on machine shop for crankshaft and my jug. I went with a 84.5mm wiseco piston. Hopefully I'll get it back this week.

[@BrapStuff]

That one is not so critical, but you can put a little on both sides if you want! Let me know how it goes!!

[@omarsalinas5629]

Thanks. I'll let you know. I am gonna call the machine shop tomorrow and check on the progress. Maybe they will push it out by the end of this week! Thanks again!

[@Patrolsjefen]

Great video :) im going to split my 93 trail boss 350 engine soon,do i need that special tool you made from pipe on my engine? where can i buy that tool ?

[@BrapStuff]

The tool for the slotted nut? If so, you can buy one, make one, or use a hammer and a pipe. Remember it's reverse thread.

[@Patrolsjefen]

@@BrapStuff thanks for fast response,i did find it on ebay :)

[@osbornebay944]

@@BrapStuff ll make one quickly using grinder, to achieve the correct torques. There is no direct visual access to crank drain nut, l ll make a hole on frame plate for sockets access.

Exellent movie. Thanks

[@liadgezz]

Exellente.thank you

[@ramonbonilla9970]

buenisimo moltobueno video grace

[@neo24ny]

Do I need the counter balance shaft if I'm not using the water pump?

[@BrapStuff]

The splines on the counterbalance shaft also run the oil pump. Fixing it back to OEM specs is always the way to go.

[@osbornebay944]

Haha, it is a crank case drain but off, that all the steam blown off from....
