door check arm rubber

[ggdad1951]

I fab'd up my new rubber stops last night, but made them slightly thicker and larger OD so the door won't open quite as far and hit the fender like the truck did originally....any thoughts on that?

And yes, I know the originals didn't if the parts were fit properly, but I'm more worried about someone or something pushing on the door harder than expected and messing up the paint.

I think you did well. Could be the rubber gave on a hard impact like the wind catching the door or possibly the rubber got weak/shrunk as the truck aged.

does the fatter door check rubber allow engagement of the latch to keep the door open? if not then welding the hole, shortening the arm a tad and drilling a new hole will fix both problems at the same time..

latch to keep the door open? I honestly have no idea what latch you are talking about! When I took the orignal I had left (one rotted to almost nothing, other in suprisingly good shape but hard) and stuck them thru the holes there was no "latch". They just slid in and out.

I wondered about that. The cars have a latch on the door check arm to keep the door open. I knew my truck didn't have that system.

was not aware the PH truck did not hold the door "latched" when opened fully like cars of the era does....so just assume wrongly it appears that this feature was across the board..

I have had to repair a good number of these latch features as they do get pulled out of the inner panel with stretched metal and metal fatigue the issue..rarely does the rivet fail..

The trucks were very utilitarian. They didn't have this stuff. The 46-48 plymouths have a starter button and in second series 49 went to key start. The pilot house trucks still have a floor activated starter. Elec wipers were standard in 51 for cars not for trucks. Stuff like that. Heck my 46 doesnt even have a sun visor on the drivers side.

My 1950 B2B has the door latches to hold the doors open. One side was good, and I had to repair the other side as it had been destroyed when the door was forced open at some point.

The little bumps on the end of the check arm are part of it. Should have noticed a bit of resistance when first installing them through the door slot.

yah, pretty much nothing there, so most likely worn away. It'll be what it'll be I guess. thanks guys

The door check with new rubber should keep the door from opening beyond 90 degrees. If you are using the rubber as a stop for the door, it sounds like there is something missing from the door itself. With a new rubber cushion installed to the check arm, the check arm is installed from inside the door through a clamping bracket that is riveted to the inside of the door. On my '48, this bracket is missing from the driver door so that when the door is opened beyond 90 degrees, it bounces around but does not hold the door open. The passenger door check is shown, and when the door reaches about 85 degrees, there is resistance to open it further as the clamping bracket engages the door check arm clamp. It takes a bit more effort to make the door open a full 90 degrees as the clamp springs are forced open while passing over the clamping bracket.

yep, mine are mostly gone (75%) only the passenger door has anything and olnly the top one. A little late now, since I've never known these were EVER there. Maybe a good idea to oversize the bumpers.

I remember discussing these door check arms in this post... http://www430.pair.com/p15d24/mopar_forum/showthread.php?t=25939&highlight=DOOR+CHECK . Ours here in Oz appear different to yours in the States. I like the door latch feature that your check arms offer over there. I have seen numerous trucks over here that have the tell-tale crease down the door indicating that the door has opened too far against the back edge of the guard.
