Hey all! New to the site. I have read over posts many times in my past ownership of LR's and RR's.
Recently purchased a '98 Discovery 1 with 198,000 showing on the clock. I don't believe it is correct. After the initial cleaning, bulb changing and look over things to do on a new purchase, it was definitely someone's donor. That's cool. It's very clean, perfect body, near perfect interior and mechanically very sound.
I was driving home one night and the water pump disintegrated. Stopped and had it towed home the next morning. No signs of head gasket / block issues. Replaced timing chain / gears, oil drive gears looked good, very slight scoring on timing cover, cleaned oil pan (not too nasty inside), have a new fan and clutch to put on.
Here is the issue. I installed new front seal and the harmonic balancer (got it very tight and was not loose), and cranked her up. Slight upper end ticking (that went away), but the crank pulley has a very bad wobble. Took it off and my neighbor helped me check the Crankshaft (used a fancy micrometer set up), and it check out fine. Now doing some research on buying a used harmonic balancer, I'm finding various weights for them. The one that I have is a 15 gram and don;t know if it's the original. Were each of these balanced to fit at the factory? I feel foolish, before the water pump went, I never looked at the pulley to see if it had a wobble. So, I don't know if it caused the water pump failure or vice versa. What weight do I need and how can I tell? Anyone have one for sale? Thanks!!!
