My pedal assembly is tired and worn. What modifications can be done to improve the operation of these units?
I don't want any cable or hydraulic systems just the Rat trap version.
Firstly where the pull rod bracket runs on this pin, it has worn a groove. (how to fix?) Can you get new pins or weld and file?

Then the main shaft is worn where the clutch pedal runs. Can you get new shafts or weld and file, or grind off end weld, remove shaft, weld worn section then finish in lathe? Is that end weld factory? (doesn't look it) The holes through the clutch pedal are enlarged so there is slop on the shaft.

Now those are just repairs, my modification is to fit a tube through the clutch pedal like the main bracket has a tube therefore spreading the load on the plastic bushs. Anyone see an issue with this?

I haven't checked the Rat trap yet but know they get sloppy too, so if you have some mods or fixes please let me know.

Also if there any other threads with other ideas please link them.

Cheers

If you need any spare parts for your rat trap marty i got a box of them not all parts but some left overs

If it were me I'd just attack it with the welder and tighten everything up

Almost finished my mod and very happy with results so far.

Machined up a bit of tube and drilled the hole in the clutch pedal larger.

Won't know if this will work until two years time but i'm feeling confident.

I presume these holes should be round?
Right hand one looks made that way but other has wear.
Anyone know for sure?  ImageUploadedByTapatalk1367307877.085657.jpg   89.31K   9 downloads

Yes they do wear and No they are not round.

They all seem oval so I'll make them look like the least worn one.  ImageUploadedByTapatalk1367313184.217470.jpg   90.14K   9 downloads
Thanks

What are my options for these two bits?
Do they sell the rivet thingy or clutch adjusting nut?
Or do I have to make, sort of part that is neon impossible to find second hand without wear.

The rivet thing was never sold separately. They only came as part of the relay lever assy.

I modified a bolt to replace the rivet thing then zapped it with a bit of weld to hold it in.

 

The clutch pushrod nut could either be built up with weld and machined or have a complete new part made.
