Beware of the BDX oil pump delete.

[BD-Xtreme]

It looks like I need to step in and shed some light on this question. The problem that the first post was not because of the oil delete kit. There is a ball bearing that supports the water pump side. We support the oil pump side with a bronze oil bushing and if there were an oil lubrication problem it would go out well before the ball bearing would ever go out. When the 2003 SnoPro came out without the oil pump they had issues with the waterpump shaft seizing to the aluminum support housing because the trust washer would not permit any premix oil to get into the aluminum housing People tried putting gease zerks on the cover plate but it required daily maintainance. We developed an oil impregnated shaft support bushing which eliminated the maintainance issue. We have had them in 1,000's of sleds since 2004 and have tested them in sleds ranging from 440's to the 1200 turbo's which some have now over 6,000 miles and no issues at all. The only recommendation that we give our customers is a 40:1 premix instead of the factory 50:1. There have been people leaving the thust washer out ( which we give instuctions and pictures to show that it must be installed) causing the shaft to gaul the housing, thereby causing failure. Doing air pressure checks between the two crank chambers while running shows adaquate mist oil lubriction to the worm dive gear and the waterpump ball bearing through the crank bearing seals. We have tested and evaluated this product for 6 years and have run these on every sled we have ridden and have never and I restate, never, had a single issue with it when following the instuctions. Now there can always be an exception to every products use due to us all being human. If we could get the failed shaft and bearing and delete housing back to us we can evaluate the disstructive analysis and come back with a finite analysis of the cause of failure.

9lbs in weight savings

i filled up my oil resevoir with water and weighed it, 8 pounds not including the linkages. oil would probably weigh even more.

i have also heard the stories of the pump boss arm falling off.

i took a syringe and squirted some oil up in the hole before i capped it, 400 miles and no problems.

overall a pretty good weight savings for the money. i have stripped 40 pounds my '09 m1000 and scream like a little girl on powder days-(powder days, remember those...ugh) when i can steer it with my feet. most "flickable" sled i have ever owned. reminds me of the old stand up jet skis and how you could just dominate them on the water.

Larry, doesn't oil float on water??? (so it should be lighter right?)

hmm...

not sure...

sounds like a good science experiment for the krug twins next year...

tried out a new secondary spring up at jp yesterday. i didnt see you flying through the air but it sounds like you were rounding up parts.

 

[m8magicandmystery]

piece of mind

i just finished reinstalling the banjo in bottom of crankcase and put the 1/8 hose into a longer 1/4 hose..you can use plug or vent on top to adapt to the 1/4 hose .....took between 2 to 3 ounces of oil to fill cavity/hose and give me static reading part way up hose ...

 

[montanasledder]

i ordered the kit but now im not sure which way i want to go. I beleive BDX knows what there doing but hate to risk losing brand new engine in sled. Darn. anyone else run there kit? I guess when all the stuff gets here ill study the instructions and see how i feel after that.

 

[scaldedcat]

Mike, I just read your post and I think we have some confusion in what appears to have happened. Remember my sled in an 2008 M 1000 EFI, I see you say in your post that there is a bearing that supports the water pump side of the oil pump shaft.This is not what I saw when I tore the motor down. What is shown on the Arctic Cat site Part # 3007-253 a water pump "bushing" seized to the oil pump shaft part # 3007-295. I don't recall seeing a "bearing" when I rebuilt the motor.And I can't seem to find the water pump "bearing" that you were talking about on the Arctic Cat micro fish. The shaft seized to the "bushing" and caused it to bend and shear the brass gear on the crank.
I'm glad that you have never had any problems with the elimination kit
but I can tell you that this appears to be oil related. I was running 40 to 1 as instructed.I will see if I still have the parts as they were at my friends garage and I will get them to you if I can.
I THINK I HAVE FOUND THE PROBLEM I HAVE NO "BALL BEARING" ON MY WATER PUMP!

I just lost my pto rod bearing. I still have the stock oiler.
My sled uses so much oil, I'm surprised that the bearing failed.

Any good crank rebuilders out there?

x2 wheres my ball bearing. must have fell out the tell tale hole. i to was running 38to1 premix, would like to know the real reason for the failer? is it possible some of the cases have slightly different clearances and not getting enough oil misted in?

 

[1100Cat]

Well though bdx had a good reassuring reply about the shaft being supported by bearings on other end in the block. Well just as the others above stated the cat microfiche and a cat technician says there is no bearings in there only a bushing(3007-253). Would like a response from BDX to clear up there above post about the motor having bearings on waterpump shaft when in fact it is only a bushing.

 

[scaldedcat]

Mike from BDX I got the shaft with the bushing seized to it.I also have the
oil pump elimination kit. If you want it to inspect it and maybe you can figure out why it went. I will send it to you just send me an address. It sounds like you are in Jackson Hole this weekend so just let me know when you get back.
Thanks Scaldedcat

WOW sorry Mr. BDX, but it sounds like someone needs to hire a new R&D dept. or a new designer or something. First the bumper problem and now this. Once again forcing people to Jerry Rig something together to make some high priced parts work.

 

[SnowBound]

Well I have the BDX oil delete in my 07 m1000. I've had it for 600+miles, I havn't had any problems. But now with all these post I guess I might as well pull it before there is a problem just to check and see if there is wear or no wear. Ill post what I find.

 

[SoGrand]

I replied in the other thread and i will do so here. As long as you mix the fuel and oil right and the right amount of octane that your sled needs due to the mods you have you will not have a problem with the delete. Ask all the racers out there with mod sleds and stock race sleds that know how to mix there own fuel that have ever burnt down there sled because of mixture problems. The problem we have had is due to leaning out the sled to get the out most performance out of it not the oil delete. Cat has not used a oil injection system in a race sled since 03. I have a 05 800 mod race sled that i have extended for out west that has way more miles on it than your 08 and 09's and have never had a problem. SnowBound the reason you and so many others have not had a problem is you are mixing your fuel right. As long as you do that you will be ok.

800 miles so far and zero problems. Could not be happier!!

i just finished reinstalling the banjo in bottom of crankcase and put the 1/8 hose into a longer 1/4 hose..you can use plug or vent on top to adapt to the 1/4 hose .....took between 2 to 3 ounces of oil to fill cavity/hose and give me static reading part way up hose ...

my static level drops overnight...does that cavity just fill up so much then bleeds slowly excess into crankcase..???.....the cavity can't be sealed tight otherwise a pressure build up right..??...so i am assuming that when i put oil in tube that a portion always stays in bottom of cavity to lube water pump bushing and shaft /crank gear..??

my shaft went at out at around 850 miles. i have premixed every sled i have owned for the last 10 years .there is an issue. what is it ,i dont know.

 

[lynxer292b]

Sounds like BDX is gunna have to find some cranks for these poor guys

I guess that the people with a left hand throttle should have a class action law suit due to the accidental new front door in their trailer I keep hearing about. If you are smart enough you can FUBAR anything.

 

[m8magicandmystery]

this ain;t my gear...but is from months ago...this issue is not just popping up...this one looks like it was just getting ready to fail on teeth and seize on bushing
