Why hello all.....

I have recently felt resistance in my RL550B..... after tearing it down, the pin that connects the crank to the bottom of the ram was the culprit.... It has galded the aluminum. I had to scrape the aluminum off of the pin and then polish it, as well as hone a new finish in the aluminum. It's working for now, but the tolerances are a bit loose. Hopefully it's all covered under warranty, but my main concern is why did this happen? Dust? lack of service? The machine has been in my bedroom since new, and has been pulled well over 10,000 times! The ram is showing some wear, and one of the link arms moves alot stiffer than the other. Should I do a complete tear down and grease it up? or is grease a bad idea? what kind of grease? silicone? wd40? white lithium? any thoughts?

thanks!

Use grease only on pivot pins. NO WD-40 EVER! We use synthetic wheel bearing grease, but anything thicker than vaseline is fine. Use 30 wt motor oil on the shaft.

It is caused by dissimular metals. Call dillon and they will send the parts you neet. You can lube the new parts
