Restoring or maintaining a Hanomag Granit 501 E? This category holds more than 120 vintage tractor parts that fit this model, clearly arranged on a single page.
Anyone keeping a Hanomag Granit 501 E running, or restoring one, ends up inside the engine sooner or later. This page holds more than 120 replacement parts for this type from GRANIT and METARO, covering the engine internals, the brakes and the cooling system. Note the naming: GRANIT is the parts brand, Granit 501 E is the name of the tractor.
For a rebuild there are main bearings, connecting rod bearings and thrust bearings in standard size, rocker arms, nuts, O-rings and gaskets, including the upper gasket on the intake manifold. Always measure the crankshaft before ordering bearings. A crank that has been reground before needs undersize shells, and standard bearings will not fit. After assembly, check the bearing clearance with plastic gauge and torque the caps correctly.
For cooling there are water pumps, a water pump bearing and the matching circlip. A pump that drips from the weep hole usually has a worn seal or bearing.
The drum brakes take new brake linings and brake shoes. Always reline both sides of an axle together and look at the drums while they are off, since scoring or an out of round drum causes uneven braking. A spring for the handbrake is also available.
A left fender and protective caps round things off.
After fitting new rocker arms, reset the valve clearance with the engine cold and each cylinder at the correct crankshaft position. Also inspect the contact face where the rocker meets the valve stem: a worn dip makes adjustment inaccurate and causes a ticking noise. Use new nuts where the old ones are damaged and tighten the lock nut properly. An O-ring or gasket that has been disturbed is best not reused. On an old tractor, that small extra effort saves a lot of hunting for oil leaks later.
On a tractor of this age, the old part is often your best guide. Check the type plate to confirm it is a Granit 501 E, look for a stamped number on the part and compare its dimensions with the description on this page. Bearing shells often carry their size on the back, and with a rocker arm, left or right matters.
There is no other type page in the same series for this Hanomag. General parts that fit several types are collected under Hanomag parts.
