Guys - what is the effect of removing the harmonic balancer?

Could you trim the diff guard to fit with the harmonic balancer installed?

Alright rofl har har. What are the consequences, short and long term of removing the harmonic balancer from the diff to fit a QT guard?? I understand that removing some parts off the car is beneficial eg.egr. What benefits are there in removing the harmonic balancer?

the harmonics wont be balanced!

Well what happens to a non harmonious diff. Does it go to a spa for the weekend to recouperate if its not feeling well, or does it see its mistress for a good lashing to smarten itself up

cant say i have noticed any effects of having it removed to be honest only that I have vibs at 110 on certain road surfaces whether that has naything to do with it I dont know..

I looked at this thread prior to fitting my front and rear QT diff guards today. After reading the post I was feeling quite positive. . . . .and then I started.

Mine is a Defender 110, Puma 2013 model.

First mistake. . . . . Doing it on my own with very limited experience of tinkering with cars. Last time I was under a vehicle with a set of spanners was on an old Vauxhall Chevette in the UK . . . . Long time ago.

Anyway this is to help future fitting by Deefer owners.

1) go to your local fishmongers and see if they have any octopus in stock. You will need all the hands you can muster.

2) if you're doing it alone get a bottle jack or something to take the load of the guards while you are postioning them

3) the front one isn't too bad but I'm actually not convinced that these fit the new Puma perfectly. On both the front and rear, the top bracket needs serious fiddling to get it to sit to the point that you put the bolt in.

4) on the rear guard you have to undo 3 of the diff housing nuts at the bottom, which end up clamping against the guard. The 2 outside ones are easy. . . . But they utilise the lowest centre nut which is easy to undo but really awkard to retighten, as when the guard is in place the nut sits directly behind the guard. It becomes one of those spanner moments where you can move the nut about 1/8 of a turn for each spanner movement.

5) when fitting the rear guard, it worked best for me to fit the top bracket as stated but also to get the bolt started which connects to the main guard at the top at rear. The alignment of the holes in the diff guard and bracket are not easily aligned. If you leave the top rear bolt until the latter stages of fitment you will end up undoing the diff housing nuts again to get slack in the diff guard to get the nut in.

6) for me the bottle jack came in handy not just to hold the guards in place while I was struggling with the nuts and bolts but came in particularly handy when fitting the rear guard . The rear guard was quite a tight fit and I used the bottle jack to gently move the guard into position around the diff housing and up to the side mounting holes.

However after all the hassle, when they are on . . . They look the muts nuts and with 5mm steel look like they will be the saviour of the diff on impact.

$300 for the pair seems like a good investment.

Where's the best place to get these from, look great!!
