165 brake issues

renegag · Jul 10, 2018

Hi, i did replace the brake discs in the old 165 last fall, only on the left side and figured I would do the right side this summer. the plates were almost welded to the shaft with rust, but other than that the actuator itself didn't seem to be worn out too much so I cleaned it and reassembled it... now the problem I have since i did the brake job is that I have to nearly stand on the brake pedal to get it to brake, sometimes more than others, and nearly impossible to lock the wheel, would just like to know if it is possible to mount the actuator backwards or something? would like to have this tractor to brake as it should because this is the tractor that I use for loading logs on the sawmill, and bushhogging and I find it pretty dangerous. Thanks guys!!

Actuator will go in either way, it's not directional. Did you replace the two discs, or clean and re-use the old ones? Also, the actuator might need replaced, or at least clean all ten ramps, and five balls. The three retaining springs MUST not be stretched either, or the brakes won't release right. Also make sure the brake rod pin is clean, and the half moon swivel is not sticking in the arm. All moving parts must work freely for the brake to apply and release correctly. Make sure too that the discs slid freely on the axle splines, rusty splines won't let the discs "float" as they should.

I put some new discs in, wire brushed all the contact surfaces and took apart the actuators, sanded the ramps, balls, and the springs were or seemed good, all the linkage were free and showed no major wear. the old disc were welded on the axles with rust, but I cleaned everything up with a wire brush and a grinder... maybe I should buy 2 new actuators. Are these tractors supposed to brake with little pedal effort or you really to apply a lot of pressure on them to get them to brake? mine never worked correctly anyways, Thanks!

Hi, I have found that just cleaning the ramps and balls is not good enough. On worn actuator discs you will find that the balls have worn a 'pocket' at the bottom of the ramps. This is likely to be minimal but it will upset the braking. Emery tape can be used to flatten the ramp a little. Dieseltech has summed up the situation but in addition I have found the following very successful; clean the ledges in the axle housing with a sanding disc so that they are flat and shiny. Do likewise with the actuator lugs. Smear a thin layer of copper grease on these faces before fitting. Do not put any grease on the ramps. When adjusting, allow a little more pedal travel than normal.

Thanks guys, I will recheck everything and maybe put new actuators in as well
