Re: Shock Dyno

Brian, I don't think the larger piston would do much good for our needs - this is what the manufacturer offered when I inquired. I was just curious to see if they might have some improvements... The larger piston would provide more force for a given pressure and that might be useful for stiffer shoc...

Re: Shock Dyno

Jim, I apologize for taking this a bit off-track, but perhaps you can offer a bit of expertise regarding the shock test unit. While at the PRI show, I asked the folks that had one of these units on display about taking readings at 1 IPS or lower shock speeds. They told me that I needed to talk to th...

Re: Shock Dyno

Jim,

Can you post some charts/graphs showing the results and maybe a pic or two of the unit itself? I have one of the units that uses a stopwatch and requires manual data entry into a spreadsheet; works OK but doesn't show what is happening at the nose of the shock curve.

Re: oil pressure relief valve

A word of caution using teh chisel method on the screw. Depending on how tight it is, you may end up with a dimple on the sealing washer surface. It will not seal well when that happens, so be aware. I'd recommend machining or replacement if that happens, AND as Brian suggests, weld or braze a 13 mm...

Re: FV Meeting at Runoffs

I would like to thank the committee once again for the time and effort they put in on our behalf.

It is unfortunate that it is far easier to condemn ...

FV Meeting at Runoffs

Wasn't there supposed to be a meeting at the runoffs for the FV group? Just curious if there was a meeting, and if so, what happened. Discussion of rule changes, etc.; I haven't seen any mention of it on this forum.

Thanks.

Re: Needle Bearing Front Beam Spacers

Ed is correct in that you can't just add the bearing and washers to an existing spacer. That ones that SR is selling have a counterbore for the bearing and spacers so the installed dimensions are just about identical to the version without the bearing. These also have the OD of the spacer extend bey...

Re: Link pin shims with angled bushings

Steve, I think EVERYTHING is bending! If you look at the ratio of wheel centerline to the ground (say 11" for a 22" tire) and the spacing between the two link pins (~5.25" then divide by two [2.625] to get the ratio) you are looking at a multiplying factor of 4.19 to 1! So 100 pounds ...

Re: Needle Bearing Front Beam Spacers

Both the needle bearing spacer and the solid spacer will allow you to tighten up your A/R bar to minimize end play. Too much torque with either style spacer will cause drag in the bar as it rotates. The point with the needle bearing version is that you have hardened washers that the bearings are wor...

Re: Link pin shims with angled bushings

One point I don't think has been raised yet about the entire front suspension is that all the pieces need to be assembled so there is no free play - as that will allow movement that will contribute to camber change; the link pins are only one aspect of achieving and maintaining the desired camber.

Re: Minimum Weight Survey

Re: Cable Droop Limiter

It hasn't been mentioned yet, so I'll point it out. One of your challenges is going to be keeping the cable nestled in the pulley grooves as the chassis moves up and down. Many possibilities. It would be worth your time to research how this was done so you can learn from the trial and error process ...

Bob, Since you mentioned it, I'll comment about the idea of turning the truck into a bunkhouse. Years ago, a friend had an aluminum sided cargo truck and in cold weather that thing would just suck the heat out of you. This probably doesn't have the aluminum siding, but probably will not retain heat ...

Detached Carb Float

Just curious about why we remove the carb float from the inlet needle actuation arm. This has been done for over 25 years that I am aware of, and now I'm curious as to why. It would seem that the plastic float would be more stable if it was attached. I know that the REALLY OLD brass floats weren't a...

The rebuild kit for a 28 PCI will NOT work on a 28 PICT. The accelerator pump diaphragms are different sizes as are the gaskets for the top cover. Jim is correct about the venturi diameter. If you wanted to go to the trouble, you couldn't bore out a 28 PICT to be as large as the 28 PCI due to the si...
