Thread: Cable driven wipers

Cool

I've been chasing a 2 speed motor for mine, just because it would be nice to have... they seem to run to about $100 on fleabay, thats for a new one.

Cheers,

Adam

Problems with Holden motor.

1. Gearing does not suit most Holden engines. Really need either overdrive or high ratio transfer case if used on the road at all.

2. Carburetter does not like steep slopes - major problem for offroad operation.

3. Engine lubrication does not like steep slopes. Loss of oil pressure and consequent engine damage is likely on steep slopes, particularly if engine oil is low.

Apart from this the major concerns are how well the conversion was done. There have been reports that some gearbox adapters were not all that accurately made, and have led to gearbox and clutch problems. The standard Holden aircleaner is a bit inadequate for dusty conditions, and on the earlier engines so is the crankcase breather system.

You might try wiper motors from other english marques such as Morris 1100's, 1500's, etc. They look similar and might fit. I used to have heaps but I think I've tossed them all out now.

Agree re the below, but on the positive side:
1. They're very reliable, economical and don't leak oil.
2. Easy to work on and parts available anywhere.
2. Carburettor can be modified to cope with steeps.
3. Steeps no problem with the crankcase oil at full + ,
4. Very strong performance on low-range.

I might be biased 'cos my Shorty has a 186S in it. I reckon it all comes down to how well the conversion was done. It shouldn't shorten driveline lifespan as there's not a huge amount of torque increase over the original motor. Overdrive sure helps on the highway though.

Summary of Holden engines.

There are truths in both of the above opinions.

A lot of problems that people experience/d with Holden engines is because of poor maintenance or because they fitted a Holden engine that was worn out BEFORE being put into a Land Rover. The camshafts on Holden engines frequently were ground to mate with an automatic transmission and were not suited to Land Rovers.

Holden engines have relatively small oil volumes, this can lead to oil starvation on either steep inclines (front bulge sump) or steep decents (rear bulge sump) and it mostly depends upon which model sump is fitted to the engine. The best model sump was that fitted to the HT Holden as the bulge is in the centre.

The Holden (Stromberg) carby needs to have its float level lowered to prevent flooding on steep inclines. An adjustable main jet is an advantage.

Some adapter kits, particularly Dello, had significant alignment problems (3 planes), causing wear on primary pinion constant gears.

The clutch arrangement was a problem with some adapters. For the pre-diaphragm pressure plates, the best conversion was to use Vauxhaul Velox/Ferguson TE20 B&B clutch housing with LR springs/internals on the Holden flywheel. Some conversions used a specially machined heavy flywheel which gave better low-down low torque than the standard flywheel.

Overheating was sometimes a problem. This was often caused by lack of air flow through the radiator, the low eficiency of the Holden fan, the removal of the radiator fan cowl in some conversions and compounded by the low oil volume. Adding an efficient fan, correct fitting radiator cowling, addition of an electric thermatic fan and the addition of an external oil cooler usually solved the cooling problems.

I have a SIII 109/Holden 202 with standard gearing and it is reliable, have not had it overheat, it will tavel all day st 90KPH uphill and down dale but can travel at 110KPH if I choose to and it outperforms the original Rover 6 in every area except for low speed touque, although the additional 700cc capacity of the Holden mostly compensates the low speed torque.

So with adjusted carby and full oil there isnt really an issue with off road driving?

I fitted a 2-speed wiper motor to my IIA, just because I had one. The cable is attached to the motor, so you usually change the cable with the motor (or I did anyway).

The wiper drive spindles/gears and their housings need to be changed as well, as the 2-speed motor has a different stroke. If you use the single speed gears the wipers will wipe right off the edge of the screen.

So you will need:
(1) Motor
(2) Spindles and housing
(3) switch
(4) Wiring (I recall it is just 1 or two extra wires to run)

Holden powered Land Rovers have driven all over Australia for decades.

As with any engine conversion, it has to be done in a professional manner, correctly modifying/tuning all of the aspects of the conversion. If it's not done and maintained in a professional manner it will probably give trouble and be unreliable as will any vehicle modified or not.
