Title: Retro Fitting Clark Ranger 664C
Post by: chase.minnaar on March 20, 2020, 05:05:11 AM
Hello All

Okay, not the typical question, but please bare with me.

I have a Clarke 664C. I have recently overhauled the torque converter and transmission with new parts 
from Allied. Ranger is fitted with the DD 353

We have stopped our lumber milling operations and I looking to convert the Ranger to another purpose- I also enjoy these type of projects..

Due to the rangers heavy duty design, weight and weight distribution for pulling, I am milling the idea to adapt the Ranger to a heavy duty Agricultural tractor for the pulling of Feed trailers, Ripping and pulling of a big disk. If I do this, I will need to change the engine and replace with a 120-140kw diesel motor.

My question- can the Torque converter, transmission and drive train handle this type of increase in power? Final drive seem robustly built, so does the trainy. But I cannot find any info online

Cheers and Thanks

In the 1970's  I operated a 666 Clark skidder with a 4-53 Detroit and I worked it hard in 20" to 40" logs . the 453 had more power than the planetary cover  bolts would take, broke quite a few on the rear. Also had a clutch pac let go, the mechanic thought the snap ring holding the clutches in the cover let go.
I would not repower a 664 with more than a 4-53 or similar hp/torque engine.
