Actually that is all the good news-- the bad news is that they confirmed that the 7299 bearing was a special application that is no longer available and could only suggest one of their "600 series". The closest one in that series uses a 1/4" balls (while it appears the 7299 bearing used an 1/8" (or maybe a 1/16") ball set). Thus the closest one (# 610 1/4 V) has a slightly larger OD (1-3/4" vs 1-9/16") and a larger thickness (5/8" vs 5/16"). Both of these would cause problems with the miter gears meshing and doesn't appear to be a good way to modify the original gears to make these available thrust bearings work :(. So for now the only option is to continue with the greased bearing washers and re-grease frequently. I have pondered replacing the miter gears with slightly larger ones to accommodate the larger bearing size but appears not to be an easy fix. Any one with more "miter gear knowledge" out there with suggestions??312Views0likes0CommentsRe: Avion truck campers - Hundreds of photos

I really think that you need that bearing in order to reduce friction. I would have suggested calling Cayo, but they claim that these jacks never came on our campers. My next guess is to take a bearing down to one of the large bearing companies and see if they can match it. I'll bet that they are still available, you just need a make and number. I didn't see any numbers on mine. I looked for numbers just in case I needed new ones. Let us know what you find out. I was able to read the bearing make & model off the original and did try to have both NAPA and a major bearing supplier cross the numbers but no good. (I don't remember what the make/ numbers were right now and on-the-road so can't refer to my notes) Anyway, yes the drag gets pretty large when my stacked thrust washer assembly gets dry so agree that having good roller thrust bearing is important-- now just need to find where to obtain-- anyone out there have some ideas?? OK back home and dug up the numbers on the original thrust bearings-- NICE 7299 USA (assume they were from a domestic manufacturer-- NICE?; that the "USA" isn't part of part number also as it is on opposite diameter from other part number). The bearing appears to be a sealed roller thrust type with ID measured at 1.013" (1" nominal), OD measured at 1.570" (1 9/16" nominal), and thickness measured at 0.300" (5/16" nominal). Appears from examination that all of these dimensions are critical-- ID to fit over threaded shaft without excessive clearance; OD to allow crank handle spur gear clearance-- any larger OD and side gear won't slide onto the side shaft enough to mate with other spur gear on the threaded main lift shaft; thickness critical to allow proper engagement of two mating spur gears. Anyone have any ideas; searched the suggested VXB.com without success.316Views0likes0CommentsRe: Avion truck campers - Hundreds of photos

I finally rebuilt my La Jaqa jacks that came with my Avion C-11. They turned out real nice but they weren't that bad considering that they were setting outside for close to 45 years. They just took some cleaning and sanding, then some paint to make them look new. The rebuild looks really good and I need to do mine also but ran into a slight problem. wondering if anyone else has solution-- The LaJac uses a small, thin thrust bearing between the stand shaft housing and the bottom of the pinion gear (that the handle's gear mates against). Two of the three in my set are failed and I can't find a replacement. I have resorted to stacking some flat bearing washers, greased liberally to serve as lubrication for now but requires frequant re-lub. Any better ideas? I can find thrust bearings eith 1"id but not the small enough od and/or not correct thickness to have two pinion gears mate correctly. The od is critical to allow clearance of side on crank's pinion gear.281Views0likes0CommentsRe: Avion truck campers - Hundreds of photos

(seems heavy) Something else? Anyway, for those that have done it would you do recommend a different method and those that haven't any good thoughts? Ken Well Ken, I have not begun active work on my rebuild but have similar repair areas as you described and also debated what to use. My approach will be to replace the 3/8"ply/3/4"foam/3/8"ply with an aluminum honeycomb panel--1 1/2"thick w/ .032 aluminum face panels and aluminum honeycomb core bonded to the face panels; face panels are powdercoated a white color and were originally intended for pre-fab clean room walls. A google search for "aluminum honeycomb panel" should bring up several and I was able to obtain mine from a company called WebbCore which was good as they are relatively close to my location but there are others. Some of the exterior aluminum panels are corroded enough that i can see small holes thru the sheet-- underside of the bunk specifically but underside of wings also will need some areas repaired-- and will use the aluminum face panel as the exterior covering too. While I haven't actually done it, I am confident I have all the aspects puzzled thru and don't see any problems but as to that, time will tell. Won't get to actual work 'til later this spring/ early summer.309Views0likes0CommentsRe: Avion truck campers - Hundreds of photos
Hi garryK6, Mine is S/N S-100172 model 1153CC10G. Pretty much original and complete Delux Gaucho model with curb side sofa and extension table. Some repairs needed-- wood on top of side wings, rebuild bunk floor (intending to use aluminum honeycomb panel there), replace several lapstrake panels of front, refinish cabinets, repaint inner surfaces after removal to inspect inner wall spaces, update wiring, add wiring and attach brackets for solar panels, etc and have enough corrosion on various exterior skins that looking to treat, prime and paint exterior. Pictures to be added later. Intention is to do planning and prep this winter and dive into actual project late this spring.142Views0likes0CommentsRe: Avion truck campers - Hundreds of photos
Avion C-11-- I have been sitting on the sidelines just being a Fly-on-the-Wall but want to get more active so here goes. Perhaps you know this or not but wish to begin by saying how beneficial your efforts to document your work and the photos have been to my understanding and planning for my project. I have known about Avion TCs for many years as my Father-in-Law has one back in RI but we are on the Oregon Coast. Well happened to pick up a '66 vintage C-10 last summer locally for a good price but, as should be excepected, "requiring some work". Well having access vicariously to your project has both motivated me pursue renovation of mine and given invaluable information on what goes into such a project-- many thanks for both. OK- now for the specific reason for this post: have you considered what you will use to re-foam the interior? I see in past posts that most are using "rattle-can" spray foam (either minimal-expanding or expansive type depending on area) to patch dug out areas. I came across a source which looks to be a good kit to replace large areas-- "www.sprayfoamdirect.com/products/spray-foam-kits"; they have several but the "Green Spray Foam" appears most applicable-- the kits are not cheap but neither are individual small cans and appears the control and final results would be much better with this material. One potential aspect of the spray-can type foam I have seen is that some (all?) are not "closed cell" which means that over time I would be concerned that the area would absorb moisture from various potential sources-- condensation on interior surface, leak (hopefully not but potential), etc. What are you planning to use and/or have you seen the product in the above link and your thoughts. Anyone else using something similar? Thank.142Views0likes0Comments
