Description
GMB GUA-13 universal joint for agricultural driveline and PTO shafts. Made in Japan by GMB Corporation. New old stock, never fitted. The box shows storage age. The part is new and unused.
Five in stock.
What it is. The GUA series is GMB's range for European style farm machinery. GUA-13 has 30.2mm caps and measures about 106.3mm cap end to cap end. It is sold on size, not on a tractor model.
Cross references. The MCB catalogue lists GUA-13 against Spicer K5-A536, Precision 330 and GKN HS179. It also appears as EG70. Precision 330 and GKN HS179 are the same numbers MCB gives for the common 30.2 x 106mm joint. If your old joint carries one of those numbers, it points to this size.
Sizes vary a little between catalogues. We have seen 106.3, 106.35, 106.5 and 106.7mm quoted for this joint. The cap diameter is the number to match.

Fitment
Put a vernier across a cap of the old cross. You want 30.2mm, and about 106mm overall. Tell us the make and model of your machine and we will check it for you.
Fitting
- Mark both yokes before you strip the shaft so the phasing goes back right.
- Clean the yoke bores and check them for wear before you press new caps in.
- Seat every circlip fully.
- Grease the joint before the machine goes back to work.
Best fitted by a qualified mechanic.
