Clutch Thrust/Release/Throwout Bearing Part Numbers
Posted: Sun Jul 26, 2020 4:40 am
Hi All,
Thought I would start a new topic to bring all of the clutch release bearing, part numbers together with an easily searched heading.
I will start by refering to Rohan's list:
"The number 408504 hand written on the box is I believe the SKF bearing equivalent number to the RHP and FKC 6W - 1 3/8 number thats printed on the box. I have a NOS FKC one in a box exactly the same. The list below is the numbers I have tracked down. These all had plastic inner sleeves of various colours except the FAG and I believe the SKF ones which were brass like the cheap new no name ones. My no name bearings dont have that 405804 number etched on the face
Original Manufacturer Number
Ford 105E7580
Ford 105E7580B
RHP 6W 1 3/8
FAG 508458
Timken 1375
FKC 6W 1 3/8
SKF 408504
cheers
Rohan."

One number that Rohan mentions above; 405804 is also mentioned by TeeJay back in 2007:
"Hi. Anyone got any comments re the fit of a new Clutch Thrust Bearing?
I have a new bearing and when I came to fit it to the carrier, it was a loose fit.
The Workshop Manual states that it has an interference fit.
Should I fit this, or try to locate a correct interference one, if I can locate one?
It was purchased from CN, but I understand that PM also has a batch of loose bearings.
I assume that they have come from the same Manufacturer.
My guess is that the interference fit on the shoulder is to ensure that the bearing race rotates only, so am I right to think that being loose, the whole bearing could rotate on the carrier, which would damage the carrier?"
Thanks for any replies.

So, it would appear that bearing 405804 is similar in looks, but, where the correct bearing is an interference fit on the bearing carrier, this bearing is 0.002" too big and will not do the job. As Miked quoted a couple of days ago: "All the right numbers but not necessarily in the right order as Eric Morcambe would say."

I have recently bought a couple of SKF 408504 from 123Bearing:

Not cheap, but a quality bearing.
I will add, that my original bearing was made by a company called Pollard, England, 6/W 1 3/8.
