300 TDI front cover

[dero]

I have just replaced the fan bearing in the front cover of my 300TDI [ spare cover ]
If anyone has one laying around , could you please measure the distance from the cover gasket face to the pulley flange face .
I had mine on a steel work bench & measured from the bench [ face of the cover where the gasket goes ] to the flange face [ where the pulley bolts on ] . steel rule across the flange face & measured down to the bench , mine measured 93mm .
Also from reading other posts , there seems to be a couple of different seals that go in this cover , are the covers all the same ? Do both types of seal fit any cover ?
My spare cover has a metal / rubber combination seal , the only seal I have on hand is all rubber , looks thinner .
Obviously can't see the seal in the cover on the motor [ still in place ]
I have seen measurements posted of the distance from the nose of the cover to the flange face , aprox 12mm , which matches mine , but this is not as easy to measure with the falcon flange on .
All advice would be greatly appreciated before I fit the replacement cover .

I just replaced mine(D1) a couple of day ago too.
Bearing had a half a mil of lateral clacking, zero fore/aft movement(and noise) tho).
As I had to redo my harmonic balancer, I thought it was time to finally rid myself of the bearing slack having noticed it a bit over 4 years ago!
Every service I did keep a check on it, and never got any worse than the first time I noted it tho.

Anyhow, measured my old cover for 'ya, I got 92mm from flange face(front of) to surface of gasket on the cover.
I don't have a calibrated measure stick to give you 100% certainty, but ruler(set square) indicated a smidge over 92mm.

I would say your 93mm measure may be right on tho, as my flange face has a few scores/indentations that could be 0.5mm or so.

When I did my timing belt(which is when I botched the HB re-install), in the kit came a metal/rubber front cover seal, in a corteco bag.
The timing case I bought, not original LR tho .. some aftermarket maker .. the dust seal is the all rubber type. Doesn't say corteco on it that I noted.
nearly 5 years ago when I did first do my timing belt, that seal supplied to me was corteco again, but was the all rubber type.

I found the metal-rubber type was a bit easier to fit.

That's exactly what I did , except with a flange from EB falcon water pump & the tool made from an old fan coupling as per AULRO posts .
Even with the tool , I still broke the L/R flange , cracked the threaded part from the flange part .
Anyone considering doing this , don't hesitate , it is quite easy to do & the John Deer bearing is readily available & plenty of old falcons laying around .
As stated in the video , the JD shaft is hardened , I cut mine with an angle grinder , as recommended in previous AULRO post & tidied it up on a linishing belt , much easier than on the lathe & quite neat .

Glad you got something from the vid. Mike is a superstar for these things.
