Help on Avenger hd bearing upgrade parts

[pinz]

Ok so I have watched RD's upgrade vid on the conquest and looked at what parts I need to upgrade my Avenger to HDi bearings but slight confussion on the parts needed . I am based in the Uk and have not seen a kit offered in the Uk so parts I think I need are

606-88 Flange housing
101-95 bearing
606-89 bearing carrier
606-90 Gasket

but do I need an inner flange ? and if so can the old one be reused , cannot see one on the parts manual or on RD's vid , but looking at the picture of the upgrade kit from buyargo this has two inner flange plates .
I think I will also need longer bolts but apart from that do I need anything else.

I would call or e-mail the guys at Adair Argo to get some good pricing and the best advice. they give super customer service and can answer all your questions. Here is a link Tim Schafer

The inner bearings and flanges have not changed so you can reuse your existing ones.

Edit: Tim corrected me. The inner flanges have been updated and are thicker. Both the older style Avenger inner flanges and the newer HDI inner flanges will work.

Hi Pinz. Have your dealer print a copy of parts bulletin # 161. This contains all the part numbers you will need along with the installation instructions. You will also need part # 658-58 routing jig for opening up the lower body at the mid axle locations so the 606-89 inner carrier fits properly. This is explained in the bulletin. Argo has a kit available, part # 101-97. It contains the following parts for 1 axle:

1 606-88 FLANGE ASY, OUTER BEARING
1 606-89 CARRIER,AXLE BEARING
1 101-95 BEARING, BALL -1.25 x 72mm
1 606-90 GASKET, FLANGE -72mm BRG
4 103-68 HHCS 3/8-16x2.0 GR5 ZINC
4 117-29 LOCKNUT, NYLON 3/8-16 ZINC
4 108-06 LOCKWASHER, 3/8 SPLIT-RING ZINC
4 108-15 WASHER .42x.81x.05 ZINC

If you're replacing the front & rear bearings as well you will have to replace the bearing extensions as well. The old bearing extensions prior to model year 2010 will have threaded studs that are not long enough for the heavy duty bearing flanges. New 810-112 bearing extensions with nut inserts instead of studs will be required along with (1) 606-25 bearing extension gasket and (2) more 606-90 flange gaskets (3 total 1 comes with 101-97 kit).

You may also want to consider upgrading to the current production HD axles. These are the same as your original axles except the wheel mounting flanges are made of solid 1/4" steel plate. Part #'s are 810-92 for the front/rear and 810-113 for the mid axles.
Cheers.

You do not have to replace the bearing extensions on your Conquest to convert to the HD bearings. Depending on the yr, if your machine is an older Conquest, your extensions will have the inner bearing carrier built in. This can be machined out, OR you can get the adapter kit from Adair. If you have a newer Conquest, the HD components will fit right in. Either way, you will need slightly longer Carage Bolts, about 1/2" longer.

You're correct RD. Sorry for the confusion, for some reason I thought he was upgrading an Avenger. The bearing extensions only need to be replaced if you have a vehicle with the 810-91 extensions (Avenger/Frontier).

Hi Howie
It's all good

the adapter kit you are referring to comes complete with everything including the longer carrage bolts...this kit is a direct bolt on and requires no custom machining or the optional jig to modify your body

You may also want to consider upgrading to the current production HD axles. These are the same as your original axles except the wheel mounting flanges are made of solid 1/4" steel plate. Part #'s are 810-92 for the front/rear and 810-113 for the mid axles.

Just to clarify the details...the new style axles actually have a 1/2" thick solid steel plate as opposed to the older style that had two thin stamped steel plates that had a tendency to pull the studs through or break the welds

You're correct RD. Sorry for the confusion, for some reason I thought he was upgrading an Avenger. The bearing extensions only need to be replaced if you have a vehicle with the 810-91 extensions (Avenger/Frontier).

just a note...i think in the first post he states that he does have an avenger and is looking to update it to the new style heavy duty bearings...in his case, if he uses the simple adapter kit that RD is refering to but for the frontier or avenger then he does not have to attempt to replace all of the outer bearing extentions as the conversion kit comes with replacement studs that are longer than stock and will save the customer a lot of time and several hundred dollars in parts...what typically happens on a two or three year old machine when you try to remove the bolts that hold the stock extention to the frame, often several of the bolts are rusted into the frame tube... when one of them breaks off it can open a real can of worms...best to leave them in place and just install the new bearings with the simple adapter kit

Thanks all for your input . It is an Avenger that I am upgrading . We use it for work along with 2 750 hdi's they all do the same work and the 750's have had no axles break but we have bust 2 axles in the last 6 months on the avenger and this week we have just bust the 3rd axle ( all mid axles) so the plan is to replace the bust axle with new HD axle and do the bearing upgrade . If all goes well then we will replace all mid bearings to the hd kit.
So I have ordered bearing, bearing housing, flange , gasket and 4 bolts so looks like I will be fitting them Tuesday.
But if I later decide to upgrade the 4 corners whats the simple adaptor kit Obsessed talks about the only kits I have seen for the corners comes with new extensions .

On the conquest axles is it just the flange that keeps breaking off, or is the axle itself breaking. The reason I am asking is because I just was ten miles out in no mans land { back in the mountains] And the front flange broke off the axle. We were in ten feet of snow and the group was taking turns breaking trail. four quads on tracks and one argo. Thank god they were there. they pulled me up the hills after the axle broke. And I was able to limp home.
So now a axle up grade is in order. My axle have the lighter two peice flanges. Now is it just the flanges that brake off the axles ?????

I just did the same bearing upgrade on my 04' Avenger. I got the kit from Tim at Adair Argo. That is the way to go. The simple adaptor kit that Obsessed mentions above makes it much easier thas replacing the old bearing extensions. Im not sure why ODG did not do this in the first place. Its actually pretty simple.

hi OT...when the older machines run wider or heavier style tracks we often see one of two things, either the weld that holds the hub to the axle breaks, or the studs actually pull right through the lightweight stamped steel hub. The newer style HD axles that became common in 2010 seem to have eliminated these two failures. It is possible to break just about anything and we do occasionally see axles snapped off at the outer bearing and last winter actually had one break right between the two sprockets. These failures are almost always on 2004-2009 8x8 middle axles as they are unsupported by an additional bearing extension, have most of the weight of the machine on them (newer style 8x8's have the center axles dropped 1"), and this is where most of the damaging chain windup stress is created when running heavy rubber or steel type tracks.

Hope this helps a little
