Thread: 300TDI A/C Compressor Guard Help needed

My guard does not look that professional. It appears to an eyebrow fabricated from a piece of 1" wide flat that has been curved up and over the top of the pulley and welded to two bolts that fit into the vacant bolt holes at either end of the top of the compressor. I'd imagine it would take less than 30 minutes to fabricate.

I haven't that the air con compressor pully/belt is rubbing on the under bonnet insulation.

I looked in the manual and noticed that there is normally a guard that sits on the compressor to shield the belt/pulley.

I got hold of a guard, but have no idea how it attaches to the compressor. The predrilled holes on the guard do not match the holes on top of the compressor.

Can anyone help me here? Are there brackets missing?

Below are some pics of the guard, compressor and rubbing marks on the insulation.

Cheers

That looks like the guard that's fitted to Disco 300Tdi.
I don't think the Defenders had them, my 95 doesn't, it doesn't have bonnet insulation ether.
IIRC the Disco compressor is mounted differently to the defender one.

Yep, that's the stock Defender guard.

I've had to re-weld mine once, it fatigue cracked around a mounting stud.

If i remember I'll take a piccy in the morning.

Iam not sure if LR used different compressors on 300Tdi's but mine looks different to yours 86mud.

The pully is much more narrow on mine and dosent allow for another belt like yours.

Will take a pic in the morning.

Same compressor, (Sanden SD7H15) different clutch

That one looks like it's all set up to mount another as an air compressor.

Heres the pic of my compressor

I believe the issue at hand is thus...

Discos came from factory with a factory Sanden compressor, co-incidently with a guard that is the same as 86MUD posted first.

Defenders were imported sans A/C and local sourced A/C components were installed, still using Sanden compressors but generally with different lug patterns on the unit.

On a disco the compressor mounts on 3 long studs up from the front casing with that guard on top and then all bolted down with 13mm bolts. Deefers are bolted to the front engine casing from the bottom/ side. Numerous types of Sanden compressor will bolt to a 300tdi front casing. (well three that I have seen?)

I guess the simple answer for 86MUD is that gurad is for a different compressor, so either modify or fabricate from new!!!!

That'd be the one, although note that my clutch is different.
