Thread: TD5 crankshaft seal... stop leaking, you carn't!

That's my theory anyway good luck with it.

I have a feeling you might be right. Thanks for the input and advice, I appreciate it.

Maybe I will but the bullet, measure crank and take pulley to get machined

Quite possibly the bolt wasn't sufficiently torqued. The recommended tension is 340 ft/ib (460 n/m), that's tighter than FT and well beyond the scope of a normal light vehicle tension wrench.

Yes, it’s possible. The wrench I used was slipping teeth and so I may not have been able to get it tight enough. I did have a 1M length of water pipe on it though

I do not have access to a torque wrench that big so am guessing using Nm (1M @ 46kg = 460ish Nm - I think that’s correct?)

As a side note to this though, Rick from Ricks 4wd Nerang suggested 900Nm...

Did you put Loctite on the damper bolt ? Loctite would help stop it from coming loose.
I recall making two very long tools to hold and tighten the balancer bolt. I think i had 4-5 foot of flat bar or similar with holes where needed.

I've had one on the 350 for years with no probs after doing this.

cheers, DL

As I recall, Speedisleeve recommend this filling of any worn surfaces on every application.

I always used Loctite, can't remember what number, anymore.

Yeah mate, I did actually use loctite. I forgot to mention that. Rick actually advised be not to, and said do it up to 900Nm.

I used a 600(ish)mm brace with holes and a 1m bit of water pipe. I stood on the 600mm bit and gave the 1m extension a fair can of beans/a whoper of an ugga dugga

Hello. The beginning of the end perchance?
