Part time kit

[Vanny]

I picked up my part time 4wd kit for my 80 from Point Roberts yesterday. On the 14th a friend (J**p guy) will be helping me install it. I am interested in seeing the fuel consumption difference.

Don't expect to much in the way of fuel savings they just aren't there, weren't for me anyways.

I don't think anything would save you much fuel with 37's. I am only running 285's so I am hoping for some improvement. I drive 80% city so I am thinking that's where I may get some savings with less work for stop and go.

what hubs are you running? mini's?

Purchased a kit from Slee. The hubs are from Brazil, AVM. There may be other options as I see Man-A-Fre also carries a kit. No price though.

so you lock the cdl and install the hubs....what keeps the front driveshaft from being powered...not to mention all the birfs etc? I think the transfer case needs to be disconnected from fulltime to really get mpg savings.

I'm not too mechanical, but there is this big ass chunk of metal that is inserted in the transfer case. Don't know what it does but it looks heavy duty. Here is a detail of the job. https://forum.ih8mud.com/80-series-tech/220747-just-finished-my-part-time-kit.html

My help couldn't help me today so we are hoping for early July.

doesn't eh cdl switch do the same as the spool?

I repeat.

One day I will visit family in Smithers. I will then meet the famous Brown Bear and he will see I love driving. But I am far better at putting wood items together than metal ones.

I have been told that with out the CDL switch you can not use 4 high with locking hubs. 4 low will work with out the CDL. Don't how that works mechanically.

If my work shift allow this year I will try to get to Cruiser days. Famous....I dunno.... net addict I think so..


The cdl on my truck only engages when I push in the button, regardless of hi 4 or low 4. But mine is a 91. I think the later ones got a viscous coupler instead of just a differential in the middle.... I bet Semlin knows for sure the needs.

There is a thing called a CDL mod in the 80 section.... maybe that is all you need to do. A spool makes you a 50/50 4wd when your in 4wd all the time. I like the option of an open centre diff when driving on slippery mountain highways. It balances torque very nicely.
