Jc5 129 circlip issues

[rs200feen]

Has anybody had issues with there circlip in 129 boxes mines gone but my friend is telling me that it will just keep happening and i should run a 130 box and have no speedo car is a track car anyway so speedo isn't the end of the world!
But do I put the 129 back in and hope it's okay or just put the 130 in and have no speedo but no circlip issues either

Put a bolted diff from a 130 into the 129.

You can also purchase a Renfort plate on ebay which you drill and tap to provide a bolted plate to secure the shaft.

Is this a common fault like its not if it will come out but when ?

 

[MarkAllsop]

Yeah pretty common on PH1's get a Renfort plate off eBay, About £50ish I think

 

[bashracing]

Perfect excuse for a quaife diff

mine popped on my mk1, replaced it twice, second time welding it. They lasted one drive each so would say just replace the box. Friend of mine has recently had his box rebuilt and a bolt in installed for around £300

That's cheap for a rebuild

that's because you can't rebuild one for £300 :wink:

I know, mine is currently being done and it's more than that haha

Parts alone on PMS are £320... And decent gearbox builders are few and far between!

You popped one that was welded in?

The guy I picked up my 172 from said the gearbox on the car had also spat one out after it was welded.

 

[Jamie86]

Must of been some crap welding then. Which not surprised by as a pain to do being high carbon.

 

[RichValver]

yup, no wasn't the best welding tbf

That's not everything either.

Renfort plate is easiest solution. Had no issues with mine once fitted

It's me who's had my williams box rebuilt, I paid £350. Agency transmissions rebuilt it, which I've heard great things about their work.

What did they replace out of interest?

 

[Chowny]

the gearbox had a leak, so the casing was changed, I bought the bolt in diff clio off Ebay, that's £50, so he fitted that, then replaces all seals and o rings, stripping the box down to check for any damage. It's with a 12 month warranty so hope everything is good, fitting it next week.

absolute minimum :wink:

Ahh right, so no synchros, gears or selector forks then. You would have been into twice that price if so.

absolute minimum :wink:

Yep.

 

[Chowny]

It was only a leak they needed to sort out, then changed wear and tear items within the box.

Love how negative people are ai!

 

[JamesBryan]

Not negative as such, it's just with the post saying 'rebuild' and '£300' the two don't go together when it come to these boxes.

ok maybe my wording was incorrect, but for the purpose of this thread where the chap has a popped circlip, fitting of a bolt in diff and reconditioning of his box would be around £350 if that is the route he wanted to take. Does that keep everyone happy?

Yeah that would be/is right.

 

[bloke]

cheapest/easiest option is stick a renfort plate on the diff.

once you open a box up 99% of the time it's never just new bearings and seals etc. add a couple of gears and a selector fork to a rebuild kit and you're over £400 for parts alone.

Ive had circlip issues with my gearbox and ended up putting a bolted in diff into my speedo drive casing so have the best of both worlds, didn't cost anywhere near £350, was £150 but didn't have anything renewed other than a diff swop

If anyone is selling a box where the circlip keeps coming out id be willing to purchase it off them to put another bolted in diff into it, must be cheap though
