Not a real Gung ho day today.
Got the other axle tube cleaned up.
Both drop boxes are all spiffy now too.
Ordered the gaskets from Snowcat Pat....
His lovely wife got things all handled....
THANKS FOLKS....
Spent more time on ebay snooping out more 6014 bearings for the drop boxes.
Two coming out of Macedonia.....great price too..
One coming from California
One from New York
Enough so far for one box.....
But the prices are averaging about $20 each.....
When ya gotta have bunches...ya got to shop around.
I am not excited about the Chinese bearings...but several of the big name U S companies are getting their stuff made over seas.
I have found so far
MGM Radak
SKF
PEER
BL
A Chinese made one called "Premium" with just the number on it.
NSK
Link belt
Should have more at the post office tomorrow.
Even the local wholesale bearing houses are pretty spendy on the bearings.
The two pinion bearings cost $80 for the pair...The big roller bearing just behind the pinion is more expensive than the other bearings....and tougher to find
The two main carrier bearings $50 for the two
The 8 bearings for the drop boxes are all over the map.
$19...$15...$27 each (Two out of Europe were $54 for pair)
Still watching a couple sellers.
I want to see what the stuff I bought looks like.
If good..will buy more...
Ratty old boxes is fine as long as the goodies are in good shape...
I will be real happy to have the big gear box back together and in the cat...
(1) 6309...Pinion at drive yoke
(1) 1310...Pinion at bevel gear
(2) 6311...Carrier
(8) 6014...Drop boxes
(2) 5210...Axle shaft outer end by sprockets
A metric buttload of bearings...
A note to anyone snooping about to find bearings.
Avoid bearings marked "C3" these are a looser fit bearing (Internal clearance)
The 1310 roller bearing behind the pinion gear is an odd duck.
This bearing needs to be a caged roller bearing and NOT "Full compliment"
The Full compliment is rated at 3000 RPM MAXIMUM (Drive shaft RPM)
The 1310 is available in many prefixes and suffixes.
The one I got is an MS1310EX...This bearing has a inner race with a flange on one side and a side plate on the other side.
This bearing will work in this application as the side plate will be captured by the center tube on the pinion shaft and this keeps the bearing solidly located.
This bearing is good for 5600 RPM....
The 6014 can be had as
"OPEN" no seals or shields
"ZZ" suffix ...both sides shielded with metal shield
"2RS" both sides sealed with rubber type seals
The shields and or seals can be easily pried out/off and tossed to give an open bearing.
The 6309 is about the same deal
The 6311 is also the same game
The prices on ebay are very good...
Just avoid the C3 designation and you can remove the unwanted seals or shields and toss them.
The Japanese and European bearings are top notch as are the US made stuff.
The Chinese bearings are in many cases made to ISO9001 standards
I have not had much experience with bearings from that side of the pond.
I did put a front wheel bearing cartridge in our 2007 Avalanche 4x4
It was a CCCPP brand.
Been in the rig 2 years now and no issues.
Fit and finish looked great....
Guess I am just a tad cautious on the bearings for the cat.
I think the larger bearings in the sizes needed for the OC12 are just fine from the folks in China.
I will not start a debate on the merits of any particular brands.....
The only bearing that is finicky is the 1310 pinion bearing due to the many configurations that it comes in.....
You can get great deals online...just be sure and pay attention to this bad boy...
Hope all the bearing stuff help someone...
I beat my head on the wall for many hours sorting out all the prefixes and suffixes stuff...
Most of it is not a big deal...but some can be....
A pix of the one pinion bearing to stay away from.
These are called "FULL COMPLIMENT" type and will carry a bigger load...but the RPM rating is less due to MORE INTERNAL FRICTION
Just an FYI
I ordered the full compliment bearing by the number only...then got to looking at the bearing when it got here...then asked What is the difference and why.
Reading bearing specs books will make you crazy.....and make ya want to chew the tracks off your cat...
All for now....
Tomorrow gotta wash out the main diffy case and go get a 9/16" hex tool to get the drop box oil plugs out.
The small 1/8" pipe drain plugs were stuck tighter than a bulls azz in fly time.
The hex striped out..
Drilled them and used an easy out.
Re tapped the threads to clean them up..
Will install new hex head plugs there...
The carnage never ends with this cat....
