mike2wheels Report post Posted September 23, 2022 The manual for my 2006 Holiday Rambler Endeavor says most of the chassis grease fittings get lithium-based grease. Except for the S-cam slack adjusters, where I'm supposed to use a clay-based grease. Why the difference? The lithium is high pressure and water proof; seems like it would work fine. If you're greasing your chassis do you use clay-based grease? I'm trying to avoid having 2 grease guns. Share this post Link to post Share on other sites
jleamont Report post Posted September 24, 2022 Mike, the recommendation is due to the extreme heat potential and the location, the slack adjusters and S-Cams get a constant pounding of water when driving in the rain. I do not use clay grease, as I don’t want two grease guns either. I lube our coach 2x per year to make sure no water penetrated, after 8 years I’ve never had any melt away and no water intrusion, I run this product https://www.pro1industrial.com/ep-1-synthetic-grease Share this post Link to post Share on other sites
rayin Report post Posted September 25, 2022 (edited) IMO grease temperature rating and grade are the most important. Some grease types are not recommended for the automatic slack adjusters, but as far as I know S-cams are not included. #2 grease is soft so it will fill voids, which eliminates the chance of water collecting and causing damage. ref: https://www.bendix.com/media/documents/press_releases/2015/TechTip_S_CamMaint_FINAL0615.pdf NLGI consistency table NLGI number ASTM worked penetration (10–1 mm) Appearance at room temperature 000 445–475 very fluid 00 400–430 fluid 0 355–385 semi-fluid 1 310–340 very soft 2 265–295 soft 3 220–250 medium hard 4 175–205 hard 5 130–160 very hard Edited September 25, 2022 by rayin Share this post Link to post Share on other sites
wildebill308 Report post Posted September 25, 2022 I started using STA-LUBE wheel bearing grease years ago because it realey did stay in the bearings, even after 10-15,000 miles. When you pulled the bearings out they looked like you just packed them. I had a 1967 Chevy 1/2 ton that was tough on bearings and after as little as 5,000 miles there would be no grease in them and metal flakes showing up. I would use their brand (appropriate grease for the application) grease on most everything. After all you have to like a place that says their products are “Intentionally Better Products.” https://www.crcindustries.com/products/grease.html This would be my recommendation.
