Hydraulics

We Do so much more than crimp and change hydrauliclines.

Hydraulic Cylinder Rebuilding — Single Day Service

Most of the times we can yank your cylin­der, pull it apart at the job site, slam the gland nut apart, replace the seals, and using a torque mul­ti­pli­er, torch­es, and air, resem­ble the beast, rein­stall and usu­al­ly you are leak free and ready to go by the next morning.

Hydraulic Kid­ney Loop Tank Filtering

Large 50-to-500-gal­lon hydraulic tanks hold thou­sands of dol­lars’ worth of flu­id. It’s sim­ply too expen­sive to replace when nor­mal con­t­a­m­i­na­tion of water and met­al debris cycles in.  Kid­ney loop fil­ter­ing or pol­ish­ing is the answer.  With­in 24–48 hours, your flu­id is clear, clean, and water free!!!

Leak­ing Hydraulic Lines in Tele­scop­ic Han­dler, Tele­han­dler, Long Reach Fork­lift, Gradall

In the field, we change out long run hydraulic lines for tele­scop­ing fork­lifts. 1 day replace­ment ser­vice for three boom, 2–3 day ser­vice for 4–5 boom. Noth­ing worse than lift­ing a stack of 2x4’s to the fourth floor of a build and have your equip­ment drip all over the job and even on your head. 

Hydraulic Pow­er Loss and Hydraulic Speed Loss

Lack­ing hydraulic pow­er and speed?  We diag­nose for worn pres­sure relief cir­cuits, bro­ken relief springs, bro­ken swash plates, spool valve leaks, restrict­ed hydraulic flu­id flow, faulty pilot sig­nals, bypass­ing cylin­ders and pumps, faulty pres­sure and tem­per­a­ture sen­sors, unbal­anced cir­cuits etc.. Leak­ing hydraulic pumps ad hydraulic motors

Hydraulic Line Replace­ment for split, cracked, cut, worn hydraulic lines

Our bread-and-but­ter work.  No hydraulic line is too dif­fi­cult to replace.  We are able to snake lines through the tough­est of spots. We work with all the pop­u­lar hose fit­tings JIC, NPT, SAE, ORF, ORB, DIN Met­ric, BSPP, UNF, SAE Straight, Met­ric Straight, Code 61 Flange Head, Code 62 Flange Head… 

Weld­ing, Fab­ri­cat­ing and Set­ting Up of Hydraulic Sys­tems from Sin­gle Line to Whole Pieces of Equip­ment to Fac­to­ry Floors

We can clean up your rats nest of dan­gling hydraulic lines,  as well we pro­vide weld­ing and fab­ri­ca­tion ser­vices used to sett up new path­ways of line rout­ing and insu­la­tor points. Pump Rooms, Recy­cling Pro­cess­ing Facil­i­ties, Car Car­ri­ers, Drill Rigs, Min­ing Rigs, and basi­cal­ly any­thing hydraulic!!        

Seized & Rust­ed Hydraulic Cylin­der Pin Removal

Are you strug­gling with a seized cylin­der pin?  We have devel­oped a very effi­cient process of blow­ing out the seized, knarled, rust­ed cylin­der pin with­out destroy­ing the cylin­der, yoke, or equip­ment.  Lots of water, fire, air used togeth­er to get that thing out.  For those who have strug­gled know!!

If all you need is a hydraulic line crimped and installed we are into it. We have done many small jobs on Skid Steers, HWH Lev­el­ing Jacks & Slide Outs, Steer­ing / Hydra­boost Brak­ing Sys­tems all the way up to 40 foot runs through inter­nal boxed frames on car-car­ri­ers, 50 to 70 foot runs on dou­ble knuck­led fiber­glass booms for Buck­et Trucks and even weaved lines through a labyrinth cur­tain wall of hydraulic hoses for cave bur­row­ing /drill rigs.  We’re into it.  But there is a lot more to hydraulics and we offer the full line of services.

Three of our ser­vice trucks are equipped with iden­ti­cal $5000 hydraulic test kits.  The team at Mobile Diesel Medic will diag­nose leak­ing spool valves, sticky pres­sure relief valves, defec­tive mag­net­ic coil packs, worn hydraulic pumps, prob­lem­at­ic PTO engage­ments, slip­ping Mico brakes, bro­ken pow­er unit shaft cou­plers, pulse width mod­u­lat­ed con­stant flow Japan­ese hydraulic boom lift sys­tems etc, etc…

We have the capability to dial in pilot signals for all hydraulic controls, pressure relief points for multistage hydraulic systems.

If you have a con­t­a­m­i­nat­ed hydraulic sys­tem on a large capac­i­ty appli­ca­tion, instead of wast­ing thou­sands of dol­lars replac­ing the flu­id, let Mobile Diesel Medic Kid­ney Loop your sys­tem.  We will set up a 2 micron fil­tra­tion loop and get all met­al, dirt, water out of all com­po­nents all the way to the extrem­i­ties of the lines and cylin­ders.  At the end of the day the flu­id will be pol­ished and ready to get back to work.

 

IN THE FIELD we have rebuilt cylin­ders on yard goats, scis­sor lifts, fork­lifts, end dumps, boom lifts, pro­duc­tion hydraulic press­es, assem­bly line equip­ment, etc… and got the equip­ment up and run­ning by the end of the day.

IN THE FIELD  we have dis­as­sem­bled mul­ti-stack spool valve con­trol blocks, resealed the leaky units and got the equip­ment run­ning the same day.

IN THE FIELD we have pulled PTO’s, dead man brake com­po­nents, hydraulic motors, resealed and rebuilt them and got them rein­stalled in the equip­ment by the evening. 

 

We at Mobile Diesel Medic only do mobile and there­fore take very very seri­ous in per­form­ing real repairs in the field and not the “band-aid” mobile repair.  This means we stock a ridicu­lous amount of con­sum­ables and seals in all our ser­vice trucks and make every effort to get your equip­ment up and run­ning when­ev­er pos­si­ble on the same day.  Please give our ser­vice a try. 

There is no risk to your wal­let using our team of tech­ni­cians.  We proud­ly hon­or our no risk 20 year pol­i­cy of not charg­ing the cus­tomer if we can’t diag­nose your hydraulic prob­lems.  But in the end we always are able to diag­nose, repair, and get-er-done.
