A-RANGE of bearing wedges has been introduced by the Martindale Electric Co., Ltd., Westmorland Road,. London, N.W.9, to overcome the problem of removing bearings, sprockets and gears which are flush against a surface and where there is insufficient space for the insertion of standard puller arms. The !quipment complements the company's range of pullers, The wedges are available in three sizes .tp to 51 in. The back of the bearing wedge is flat whilst the inside is concave sod has a finely tapered edge. This mables the halves of the wedge easily to Je inserted between 'the back plate, or )ther surface, and the object to be .emoved. The puller is then attached so hat the arms grip the bearing wedge irmly. Tightening of the wedge bolts 'orces both halves closer together until 'ull contact is obtained against the piece )eing removed.

fly electrically started.
For both D4 and D6 tractors operating rith front-mounted hydraulic equipment 1 atmospheric temperatures over 100° F., high-ambient-temperature radiator is vailable. It is recommended for use only overheating problems occur because f a combination of both the above ictors. The extra cooling capacity is not ceded on normal D4 and D6 tractors as le standard radiators are capable of iccessful cooling in ambient tempera
tures of 115° F. under continuous fullload operation. Reduced air flow through the radiator core of a tractor equipped with front-mounted apparatus restricts the efficiency of a standard radiator.
