Hello all,
I am making slow progress on the 1.8L 1975 Engine Rebuild. So far I have ordered new 96MM pistons and cylinders, valve springs, lifters, push rod tubes, engine seal kit and new front and rear seals. While taking off the fan hub, I noticed a slight bend in the front part of the groove for the woodruff key and not sure if this is cause for concern? Should I consider replacing this fan hub assembly or is that not enough cause for concern? I used some gear pullers so not sure if that was my doing or not. (IMG:style_emoticons/default/dry.gif)   Also, a picture of the condition of the crankshaft end with a slight ding circled in red and the wodruff key, I am planning on replacing the key of course but not sure if someone used a tool to seat it in place? No cause for concern on the crankshaft correct?   Now dealing with measuring the crank main journals to determine what bearing size to get! slowly but surely... |

Spend a little time - read the thread link, especially post #14
The condition of the hub nose is very important on these engines and yours isn’t looking great. This is a commonly neglected area of rebuilds and can have ugly consequences if the fit isn’t right. http://www.914world.com/bbs2/index.php?sho...363970&st=0 Spend the time to do it right while it’s still easy to do. |
