Clutch and lower gears

[patrolone]

Hi, I know similar threads have already been posted in the forum, but I can't find out what specific need. I usually use my 2.8 y60 with 34" for crawling. In about ten times I used it the cluth failed. I talked with my friends and I've been suggested first to use a stronger clutch like the exedy safari tuff, but even to change the ratio of the lower gears because it can help reducing the stress of the clutch itself. I don't know if it make necessary to change also the flying wheel. What do you think about this? Thanks!

Weird , I think tyres too big for the motor M2Cw,

Never heard of a clutch letting go unless you ride the clutch not adjusted properly or water in the box or clutch and towing. Get a heavy duty one machine the flywheel no need to change ratios unless doing serious crawling then just do transfer case gears

Yeah sounds like the clutch may have been close to giving up anyway. Get the heavy duty clutch and if your still keen on lowering the gears then go with what macca has suggested and get some low range reduction gears. There are plenty of 2.8's that run 35's daily so I dont think the tyres are to big.

Patrolone,

The lower ratio gears are in the transfer case, and have nothing to do with the clutch, flywheel or gearbox.

Put a new heavy duty clutch in, and putting crawler gears in the transfer case for your low range rock hopping will do wonders for driveability and service life.

Happygtu,
for lower ratio gears I meant ring and pinion in the diffs.

Do you think could be usefull to help the clucth working safer on hard obstacles?

[macca86]

No not at all. Driving style maintiance will help the clutch. Diff gears will make traveling slower on obstacles easier but will make highway driving hard work. Transfer case gears better option doesn't change on road habits only low range 4wd. The rd28 has the highest factory diff ratios anyway

For Macca, happy and Newby have you seen where this dude takes his patrol, He really needs a set of reduction gears.
full on terrain he has posted pics somewhere

[macca86]

That's what we have suggested as it sounds like he's riding the clutch too much crawling without stalling. Probably needs the 85% reduction set from marks

Patrolone,

You should definitely look at the transfer case reduction gears.... http://www.marks4wd.com/mfk1515-2-86l.html
