Here's what I'm looking for....facts and part numbers for the XR, Scorpio and Cossies. I don't want "Well I heard this, or that"... or any other hearsay. Actual facts only please.
Let's make this a useful post for posterity and end any confusion
Let's hear it
Bearing: Timken - set24
Seal: Timken - 3743 (triple lip)
Bearing: Timken - set24
Seal: Timken - 2 x 3743 (triple lip)
Bearing: Timken - ?
Seal: Timken - ?
Bearing: Timken - set24 (Admin Edit: this information has been determined to be incorrect)
Seal: Timken - 536810XX (single lip?)
My understanding is that the Scorpio and Cossie use the same (larger than XR) bearings, but I don't have any first-hand knowledge here to verify this as fact. These bearings seem to be relatively "rare" and 2 to 3X more expensive than the much more common "set 24" bearings, so I've kinda talked myself out of machining XR knuckles for these larger bearings.
I'm hoping he'll check in here.....Freejack wrote:Chuck,
Check with Anglin, I sent him a set of Scorp front hubs some months back that he was planning to use on his XR. I assuming he took them apart, hopefully he noted the bearings while he was in there...
Not to drift too far off-topic, but using the Scorp knuckle on the XR is not really viable as I had once thought. The ANGLE of the strut receiver is different between the XR and Scorpio, so it just won't line up right. If you want to discuss further, best to start a new thread - let's not pollute this one.Freejack wrote:Check with Anglin, I sent him a set of Scorp front hubs some months back that he was planning to use on his XR.

86 XR4Ti - Megasquirt n EDIS, Big IC, full 3" exhuast, Toyota 8" LSD, Spax adj. susp., RX-7 front hubs, RX-7 Brakes.
87 XR4Ti - Stock auto daily driver

I've just been doing some asking around for Scorpio bearing information myself. I'm trying to do the 5-lug conversion the way that Brad wants to avoid - by machining the XR spindles to accept the Scorpio bearings and unmachined hubs.
Terry Watson has done some PN digging into the wheel bearings for the Scorpio application and was kind enough to share the info with me. The PNs are for SKF bearings. Theoretically, the should be as readily accessible as Timken bearings. We'll see if this pans out the way I'm hoping. Here are the PNs for a variety of wheel bearings, along with dimensions and seal PNs and so forth (not all PNs are SKF PNs):
Merkur Wheel Bearing Sizes, From Russ at Rapido:
XR4Ti Front & Rear:
Cossie Front bearing measurements, measured by me:
ID: 1.489" measured
OD: 2.480" measured
Outer Race: 0.531" high
Inner Race: 0.747" high
Part # (as pulled from car): SKF F K-JL 69310-2B-VQ060
Seal # (as pulled from car): 85GB â€“1190 â€“ AA
Per SKF: Bearing replaced by: LB T1B 332821- CVQ060, available from Rapido, same as Scorpio front bearings.
Part # (as supplied by Rapido):
SKF BT1B 332821 C/Q Germany 00283T
SKF BT1B 332821 C/Q Germany 00272U
SKF BT1B 332821 B A/Q Germany L W41T
SKF BT1B 332821 B A/Q Germany L W39U
So, that's where we are at right now. Of course, I don't want to convert to Cosworth/Scorpio front bearings if it means I'm going to have to cough up $90 per side to BAT. That's painful when XR wheel bearings are 1/3 that cost through us (mcÂ²racing).
BTW....what are those last 4 SKF part numbers for? Bearings?, Races? Sets? Fronts? Rears?
