APT Rear Diff Guard Install Query

[jc109]

For those of you with a Puma 110 who've installed an APT rear diff guard, how did you go about fitting it?

I can't for the life of me see where the front mounting bolts are supposed to fit into.

I'm one of the few that had to drill these holes.
Hopefully you won't need to.


PS, PM sent.

Here is a picture of where the 2 bolt holes should be(from Defender2.net).
I had to drill and tap the holes to fit mine.
I went shallow in the hole, spacing the bolts with washers.
I did mine in the vehicle and did know what clearances I had inside the housing.

Another hint is use a thread locker so the bolts don't rattle loose.

Thanks Kyle. And sorry I missed you yesterday. This is a little daunting, as I don't want to drop everything out of the car, and nor am I confident in my ability to drill straight enough for this using my cordless drill. I suspect I might not have bothered getting this if I knew what was required.

Those holes look bigger than what I would be attempting with a cordless

What are they? M8? M10 at a stretch?
A decent cordless drill at ~90nM torque should be good for 12mm in steel.

Don't know.....they look bigger than M10 hence the question.

Each to there own I guess.....

Not sure what the good of two shallow M8 bolts is going to do.......

I had an issue installing mine, but it was to do with the hole being clogged with crap... so not an error / omission of the APT product, just a problem with my vehicle (which appear to be the same issue that is being experienced here). We should collectively curse land rover build consistency.

JC, don't let a few holes get in your way! A decent drill (corded or otherwise) and a once over with a tap will make easy work of it. Best case a fellow aulrolian might be able to get it done, or at worst a local workshop for a bit of the folding stuff. If space is an issue you'd be able to use a right angle chuck on your drill of choice, but controlling the angle will be a bit more difficult.

From memory they are 10mm bolts but I stand to be corrected.
As the housing is cast it's fairly easy to drill, particularly going up in drill sizes gradually.


From the research I did at the time I was fitting mine there seems to be a very narrow window of diff centres without the blind holes.
When I was talking to Ben at APT about it he had not heard of it before.
This is what happens when we use P38 hand me downs:wasntme:
